-.TH SMB.CONF 5 "26 Oct 1997" "smb.conf 1.9.18alpha5"
-.SH NAME
-smb.conf \- configuration file for smbd
-.SH SYNOPSIS
-.B smb.conf
-.SH DESCRIPTION
-The
-.B smb.conf
-file is a configuration file for the Samba suite.
-
-.B smb.conf
-contains runtime configuration information for the
-.B smbd
-program. The
-.B smbd
-program provides LanManager-like services to clients
-using the SMB protocol.
-.SH FILE FORMAT
-The file consists of sections and parameters. A section begins with the
-name of the section in square brackets and continues until the next
-section begins. Sections contain parameters of the form 'name = value'.
-
-The file is line-based - that is, each newline-terminated line represents
-either a comment, a section name or a parameter.
-
-Section and parameter names are not case sensitive.
-
-Only the first equals sign in a parameter is significant. Whitespace before
-or after the first equals sign is discarded. Leading, trailing and internal
-whitespace in section and parameter names is irrelevant. Leading and
-trailing whitespace in a parameter value is discarded. Internal whitespace
-within a parameter value is retained verbatim.
-
-Any line beginning with a semicolon is ignored, as are lines containing
-only whitespace.
-
-Any line ending in a \e is "continued" on the next line in the
-customary UNIX fashion.
-
-The values following the equals sign in parameters are all either a string
-(no quotes needed) or a boolean, which may be given as yes/no, 0/1 or
-true/false. Case is not significant in boolean values, but is preserved
-in string values. Some items such as create modes are numeric.
-.SH SERVICE DESCRIPTIONS
-Each section in the configuration file describes a service. The section name
-is the service name and the parameters within the section define the service's
-attributes.
-
-There are three special sections, [global], [homes] and [printers], which are
-described under 'special sections'. The following notes apply to ordinary
-service descriptions.
-
-A service consists of a directory to which access is being given plus a
-description of the access rights which are granted to the user of the
-service. Some housekeeping options are also specifiable.
-
-Services are either filespace services (used by the client as an extension of
-their native file systems) or printable services (used by the client to access
-print services on the host running the server).
-
-Services may be guest services, in which case no password is required to
-access them. A specified guest account is used to define access privileges
-in this case.
-
-Services other than guest services will require a password to access
-them. The client provides the username. As many clients only provide

+.PP
+.SH "SECTION DESCRIPTIONS"
+.PP
+Each section in the configuration file (except for the
+\fB[global]\fP section) describes a shared resource (known
+as a \fI"share"\fP)\&. The section name is the name of the shared resource
+and the parameters within the section define the shares attributes\&.
+.PP
+There are three special sections, \fB[global]\fP,
+\fB[homes]\fP and \fB[printers]\fP, which are
+described under \fB\'special sections\'\fP\&. The
+following notes apply to ordinary section descriptions\&.
+.PP
+A share consists of a directory to which access is being given plus
+a description of the access rights which are granted to the user of
+the service\&. Some housekeeping options are also specifiable\&.
+.PP
+Sections are either filespace services (used by the client as an
+extension of their native file systems) or printable services (used by
+the client to access print services on the host running the server)\&.
+.PP
+Sections may be designated \fBguest\fP services, in which
+case no password is required to access them\&. A specified UNIX
+\fBguest account\fP is used to define access
+privileges in this case\&.
+.PP
+Sections other than guest services will require a password to access
+them\&. The client provides the username\&. As older clients only provide
passwords and not usernames, you may specify a list of usernames to
-check against the password using the "user=" option in the service
-definition.
-
-Note that the access rights granted by the server are masked by the access
-rights granted to the specified or guest user by the host system. The
-server does not grant more access than the host system grants.
+check against the password using the \fB"user="\fP option in
+the share definition\&. For modern clients such as Windows 95/98 and
+Windows NT, this should not be necessary\&.
+.PP
+Note that the access rights granted by the server are masked by the
+access rights granted to the specified or guest UNIX user by the host
+system\&. The server does not grant more access than the host system
+grants\&.
+.PP
+The following sample section defines a file space share\&. The user has
+write access to the path \f(CW/home/bar\fP\&. The share is accessed via
+the share name "foo":

+
+
+.fi
+

+.PP
+The following sample section defines a printable share\&. The share
+is readonly, but printable\&. That is, the only write access permitted
+is via calls to open, write to and close a spool file\&. The
+\fB\'guest ok\'\fP parameter means access will be permitted
+as the default guest user (specified elsewhere):

-.SH SPECIAL SECTIONS
-
-.SS The [global] section
-.RS 3
-Parameters in this section apply to the server as a whole, or are defaults
-for services which do not specifically define certain items. See the notes
-under 'Parameters' for more information.
-.RE
-
-.SS The [homes] section
-.RS 3
-If a section called 'homes' is included in the configuration file, services
-connecting clients to their home directories can be created on the fly by the
-server.
-
-When the connection request is made, the existing services are scanned. If a
-match is found, it is used. If no match is found, the requested service name is
-treated as a user name and looked up in the local passwords file. If the
-name exists and the correct password has been given, a service is created
-by cloning the [homes] section.
-
-Some modifications are then made to the newly created section:
-
-.RS 3
-The service name is changed from 'homes' to the located username
-
-If no path was given, the path is set to the user's home directory.
-.RE
-
-If you decide to use a path= line in your [homes] section then you may
-find it useful to use the %S macro. For example path=/data/pchome/%S
-would be useful if you have different home directories for your PCs
-than for UNIX access.
+ guest ok = true
-This is a fast and simple way to give a large number of clients access to
-their home directories with a minimum of fuss.
-
-A similar process occurs if the requested service name is "homes", except that
-the service name is not changed to that of the requesting user. This method
-of using the [homes] section works well if different users share a client PC.
+.fi

-The [homes] section can specify all the parameters a normal service section
-can specify, though some make more sense than others. The following is a
-typical and suitable [homes] section:

+.PP
+\fB"mangle case = yes/no"\fP controls if names that have characters that
+aren\'t of the "default" case are mangled\&. For example, if this is yes
+then a name like \f(CW"Mail"\fP would be mangled\&. Default \fIno\fP\&.
+.PP
+\fB"case sensitive = yes/no"\fP controls whether filenames are case
+sensitive\&. If they aren\'t then Samba must do a filename search and
+match on passed names\&. Default \fIno\fP\&.
+.PP
+\fB"default case = upper/lower"\fP controls what the default case is for new
+filenames\&. Default \fIlower\fP\&.
+.PP
+\fB"preserve case = yes/no"\fP controls if new files are created with the
+case that the client passes, or if they are forced to be the \f(CW"default"\fP
+case\&. Default \fIYes\fP\&.
+.PP
+.PP
+\fB"short preserve case = yes/no"\fP controls if new files which conform
+to 8\&.3 syntax, that is all in upper case and of suitable length, are
+created upper case, or if they are forced to be the \f(CW"default"\fP
+case\&. This option can be use with \fB"preserve case =
+yes"\fP to permit long filenames to retain their
+case, while short names are lowered\&. Default \fIYes\fP\&.
+.PP
+By default, Samba 2\&.0 has the same semantics as a Windows NT
+server, in that it is case insensitive but case preserving\&.
+.PP
+.SH "NOTE ABOUT USERNAME/PASSWORD VALIDATION"
+.PP
+There are a number of ways in which a user can connect to a
+service\&. The server follows the following steps in determining if it
+will allow a connection to a specified service\&. If all the steps fail
+then the connection request is rejected\&. If one of the steps pass then
+the following steps are not checked\&.
+.PP
+If the service is marked \fB"guest only = yes"\fP then
+steps 1 to 5 are skipped\&.
+.PP
+.IP
+.IP 1\&.
+Step 1: If the client has passed a username/password pair and
+that username/password pair is validated by the UNIX system\'s password
+programs then the connection is made as that username\&. Note that this
+includes the \f(CW\e\eserver\eservice%username\fP method of passing a
+username\&.
+.IP
+.IP 2\&.
+Step 2: If the client has previously registered a username with
+the system and now supplies a correct password for that username then
+the connection is allowed\&.
+.IP
+.IP 3\&.
+Step 3: The client\'s netbios name and any previously used user
+names are checked against the supplied password, if they match then
+the connection is allowed as the corresponding user\&.
+.IP
+.IP 4\&.
+Step 4: If the client has previously validated a
+username/password pair with the server and the client has passed the
+validation token then that username is used\&.
+.IP
+.IP 5\&.
+Step 5: If a \fB"user = "\fP field is given in the
+smb\&.conf file for the service and the client has supplied a password,
+and that password matches (according to the UNIX system\'s password
+checking) with one of the usernames from the \fBuser=\fP
+field then the connection is made as the username in the
+\fB"user="\fP line\&. If one of the username in the
+\fBuser=\fP list begins with a \f(CW\'@\'\fP then that name
+expands to a list of names in the group of the same name\&.
+.IP
+.IP 6\&.
+Step 6: If the service is a guest service then a connection is
+made as the username given in the \fB"guest account
+="\fP for the service, irrespective of the supplied
+password\&.

+.IP "\fBadd user script (G)\fP"
+.IP
+This is the full pathname to a script that will be run \fIAS ROOT\fP by
+\fBsmbd (8)\fP under special circumstances decribed
+below\&.
+.IP
+Normally, a Samba server requires that UNIX users are created for all
+users accessing files on this server\&. For sites that use Windows NT
+account databases as their primary user database creating these users
+and keeping the user list in sync with the Windows NT PDC is an
+onerous task\&. This option allows \fBsmbd\fP to create
+the required UNIX users \fION DEMAND\fP when a user accesses the Samba
+server\&.
+.IP
+In order to use this option, \fBsmbd\fP must be set to
+\fBsecurity=server\fP or
+\fBsecurity=domain\fP and \fB"add user script"\fP
+must be set to a full pathname for a script that will create a UNIX user
+given one argument of \fB%u\fP, which expands into the UNIX user name to
+create\&.
+.IP
+When the Windows user attempts to access the Samba server, at
+\fI"login"\fP(session setup in the SMB protocol) time,
+\fBsmbd\fP contacts the \fBpassword
+server\fP and attempts to authenticate the given user
+with the given password\&. If the authentication succeeds then
+\fBsmbd\fP attempts to find a UNIX user in the UNIX
+password database to map the Windows user into\&. If this lookup fails,
+and \fB"add user script"\fP is set then \fBsmbd\fP will
+call the specified script \fIAS ROOT\fP, expanding any \fB%u\fP argument
+to be the user name to create\&.
+.IP
+If this script successfully creates the user then
+\fBsmbd\fP will continue on as though the UNIX user
+already existed\&. In this way, UNIX users are dynamically created to
+match existing Windows NT accounts\&.
+.IP
+See also \fBsecurity=server\fP,
+\fBsecurity=domain\fP, \fBpassword

-
-.SS allow hosts (S)
-A synonym for this parameter is 'hosts allow'.
-
-This parameter is a comma delimited set of hosts which are permitted to access
-a service.
-
-If specified in the [global] section then it will apply to all
-services, regardless of whether the individual service has a different
-setting.
-
-You can specify the hosts by name or IP number. For example, you could
-restrict access to only the hosts on a Class C subnet with something like
-"allow hosts = 150.203.5.". The full syntax of the list is described in
-the man page
-.BR hosts_access (5).
-
-You can also specify hosts by network/netmask pairs and by netgroup
-names if your system supports netgroups. The EXCEPT keyword can also
-be used to limit a wildcard list. The following examples may provide
-some help:
-
-Example 1: allow all IPs in 150.203.*.* except one
-
- hosts allow = 150.203. EXCEPT 150.203.6.66
-
-Example 2: allow hosts that match the given network/netmask
-
- hosts allow = 150.203.15.0/255.255.255.0
-
-Example 3: allow a couple of hosts
-
- hosts allow = lapland, arvidsjaur
-
-Example 4: allow only hosts in netgroup "foonet" or localhost, but
-deny access from one particular host
-
- hosts allow = @foonet, localhost
- hosts deny = pirate
-
-Note that access still requires suitable user-level passwords.
-
-See
-.BR testparm (1)
-for a way of testing your host access to see if it
-does what you expect.
-
-.B Default:
- none (i.e., all hosts permitted access)
-
-.B Example:
- allow hosts = 150.203.5. myhost.mynet.edu.au
-
-.SS alternate permissions (S)
-
-This option affects the way the "read only" DOS attribute is produced
-for UNIX files. If this is false then the read only bit is set for
-files on writeable shares which the user cannot write to.
-
-If this is true then it is set for files whos user write bit is not set.
-
-The latter behaviour is useful for when users copy files from each
-others directories, and use a file manager that preserves
-permissions. Without this option they may get annoyed as all copied
-files will have the "read only" bit set.
-
-.B Default:
- alternate permissions = no
-
-.B Example:
- alternate permissions = yes

-
-.SS bind interfaces only (G)
-This global parameter (new for 1.9.18) allows the Samba admin to limit
-what interfaces on a machine will serve smb requests. If affects file service
-(smbd) and name service (nmbd) in slightly different ways.
-
-For name service it causes nmbd to bind to ports 137 and 138 on
-the interfaces listed in the 'interfaces' parameter. nmbd also binds
-to the 'all addresses' interface (0.0.0.0) on ports 137 and 138
-for the purposes of reading broadcast messages. If this option is
-not set then nmbd will service name requests on all of these
-sockets. If "bind interfaces only" is set then nmbd will check
-the source address of any packets coming in on the broadcast
-sockets and discard any that don't match the broadcast addresses
-of the interfaces in the 'interfaces' parameter list. As unicast
-packets are received on the other sockets it allows nmbd to
-refuse to serve names to machines that send packets that arrive
-through any interfaces not listed in the 'interfaces' list.
-IP Source address spoofing does defeat this simple check, however
-so it must not be used seriously as a security feature for nmbd.
-
-For file service it causes smbd to bind only to the interface
-list given in the 'interfaces' parameter. This restricts the
-networks that smbd will serve to packets coming in those interfaces.
-Note that you should not use this parameter for machines that
-are serving ppp or other intermittant or non-broadcast network
-interfaces as it will not cope with non-permanent interfaces.

-
-This is useful to stop a server's resources being exhausted by a large
-number of inactive connections.
-
-Most clients have an auto-reconnect feature when a connection is broken so
-in most cases this parameter should be transparent to users.

The value of the parameter (an integer) allows the debug level
-(logging level) to be specified in the
-.B smb.conf
-file. This is to give
-greater flexibility in the configuration of the system.
-
-The default will be the debug level specified on the command line.
-
-.B Example:
- debug level = 3
-.SS default (G)
-See
-.B default service.
-.SS default case (S)
-
-See the section on "NAME MANGLING" Also note the addition of "short
-preserve case"
-
-.SS default service (G)
-A synonym for this parameter is 'default'.
-
-This parameter specifies the name of a service which will be connected to
-if the service actually requested cannot be found. Note that the square
-brackets are NOT given in the parameter value (see example below).
-
-There is no default value for this parameter. If this parameter is not given,
-attempting to connect to a nonexistent service results in an error.
-
-Typically the default service would be a public, read-only service.
-
-Also note that as of 1.9.14 the apparent service name will be changed to
-equal that of the requested service, this is very useful as it allows
-you to use macros like %S to make a wildcard service.
-
-Note also that any _ characters in the name of the service used in the
-default service will get mapped to a /. This allows for interesting
-things.
-
-
-.B Example:
- default service = pub
-
- [pub]
- path = /%S
-
-
-.SS delete readonly (S)
-This parameter allows readonly files to be deleted. This is not normal DOS
-semantics, but is allowed by UNIX.
-
-This option may be useful for running applications such as rcs, where UNIX
-file ownership prevents changing file permissions, and DOS semantics prevent
-deletion of a read only file.
-
-.B Default:
- delete readonly = No
-
-.B Example:
- delete readonly = Yes
-.SS deny hosts (S)
-A synonym for this parameter is 'hosts deny'.
-
-The opposite of 'allow hosts' - hosts listed here are NOT permitted
-access to services unless the specific services have their own lists to
-override this one. Where the lists conflict, the 'allow' list takes precedence.
-
-.B Default:
- none (i.e., no hosts specifically excluded)
-
-.B Example:
- deny hosts = 150.203.4. badhost.mynet.edu.au
-
-.SS delete veto files (S)
-
-This option is used when Samba is attempting to delete a directory
-that contains one or more vetoed directories (see the 'veto files' option).
-If this option is set to False (the default) then if a vetoed directory
-contains any non-vetoed files or directories then the directory delete
-will fail. This is usually what you want.
-
-If this option is set to True, then Samba will attempt
-to recursively delete any files and directories within the vetoed
-directory. This can be useful for integration with file serving
-systems such as Netatalk, which create meta-files within directories
-you might normally veto DOS/Windows users from seeing (eg. .AppleDouble)
-
-Setting 'delete veto files = True' allows these directories to be
-transparently deleted when the parent directory is deleted (so long
-as the user has permissions to do so).
-
-.B Default:
- delete veto files = False
-
-.B Example:
- delete veto files = True
-
-See
-.B veto files
-
-.SS dfree command (G)
-The dfree command setting should only be used on systems where a
-problem occurs with the internal disk space calculations. This has
-been known to happen with Ultrix, but may occur with other operating
-systems. The symptom that was seen was an error of "Abort Retry
-Ignore" at the end of each directory listing.
-
-This setting allows the replacement of the internal routines to
-calculate the total disk space and amount available with an external
-routine. The example below gives a possible script that might fulfill
-this function.
-
-The external program will be passed a single parameter indicating a
-directory in the filesystem being queried. This will typically consist
-of the string "./". The script should return two integers in ascii. The
-first should be the total disk space in blocks, and the second should
-be the number of available blocks. An optional third return value
-can give the block size in bytes. The default blocksize is 1024 bytes.
-
-Note: Your script should NOT be setuid or setgid and should be owned by
-(and writable only by) root!
-
-.B Default:
- By default internal routines for determining the disk capacity
-and remaining space will be used.
-
-.B Example:
- dfree command = /usr/local/samba/bin/dfree
-
- Where the script dfree (which must be made executable) could be
-
-.nf
- #!/bin/sh
- df $1 | tail -1 | awk '{print $2" "$4}'
-.fi
-
- or perhaps (on Sys V)
-
-.nf
- #!/bin/sh
- /usr/bin/df -k $1 | tail -1 | awk '{print $3" "$5}'
-.fi
-
- Note that you may have to replace the command names with full
-path names on some systems.
-.SS directory (S)
-See
-.B path.
-
-.SS directory mask (S)
-A synonym for this parameter is 'directory mode'.
-
-This parameter is the octal modes which are used when converting DOS modes
-to UNIX modes when creating UNIX directories.
-
-When a directory is created, the neccessary permissions are calculated
-according to the mapping from DOS modes to UNIX permissions, and
-the resulting UNIX mode is then bit-wise 'AND'ed with this parameter.
-This parameter may be thought of as a bit-wise MASK for the UNIX
-modes of a directory. Any bit *not* set here will be removed from the
-modes set on a directory when it is created.
-
-The default value of this parameter removes the 'group' and 'other'
-write bits from the UNIX mode, allowing only the user who owns the
-directory to modify it.
-
-Following this Samba will bit-wise 'OR' the UNIX mode created from
-this parameter with the value of the "force directory mode" parameter.
-This parameter is set to 000 by default (ie. no extra mode bits are added).
-
-See the "force directory mode" parameter to cause particular mode
-bits to always be set on created directories.
-
-See also the "create mode" parameter for masking mode bits on created
-files.
-
-.B Default:
- directory mask = 0755
-
-.B Example:
- directory mask = 0775
-
-.SS directory mode (S)
-See
-.B directory mask.
-
-.SS dns proxy (G)
-
-Specifies that nmbd should (as a WINS server), on finding that a NetBIOS
-name has not been registered, treat the NetBIOS name word-for-word as
-a DNS name.
-
-Note that the maximum length for a NetBIOS name is 15
-characters, so the DNS name (or DNS alias) can likewise only be 15
-characters, maximum.
-
-Note also that nmbd will block completely until the DNS name is resolved.
-This will result in temporary loss of browsing and WINS services.
-Enable this option only if you are certain that DNS resolution is fast,
-or you can live with the consequences of periodic pauses in nmbd service.
-
-.B Default:
- dns proxy = yes
-
-.SS domain controller (G)
-
-Specifies the DNS name or IP address of the machine to refer domain
-logons from Win95 machines to. You should never need to set this parameter.
-
-.B Default:
- domain controller = no
-
-.SS domain groups (G)
-
-Specifies the NT Domain groups that the user belongs to, and the attributes
-associated with that group. This parameter is a white-space separated list
-of group ids (in decimal), followed by an option attribute (in decimal) which
-defaults to a value of 7 if not specified. A group id and the user attributes
-associated with it are separated by "/".
-
-.B
-It is known that attributes are ignored by NT 4.0 Workstation, but not by
-NT 3.51 Workstation. Furthermore, no information on the exact meaning of
-NT Domain groups is presently known.
-
-.B Default:
- domain groups = 776/7
-
-.B Example:
- domain groups = 776 1024/7 777
-
-.SS domain sid (G)
-
-Specifies the SID when using Samba as a Logon Server for NT Workstations.
-The format of SIDs supported by samba at present is S-1-N-nnn-nnn-nnn-nnn-nnn.
-The number N indicates the number of sub-authorities (nnn).
-
-.B Default:
- domain sid = none
-
-.B Example:
- domain sid = S-1-5-21-123-456-789-123
-
-.SS domain logons (G)
-
-If set to true, the Samba server will serve Windows 95 domain logons
-for the workgroup it is in. For more details on setting up this feature
-see the file DOMAINS.txt in the Samba source documentation directory.
-
-.B Default:
- domain logons = no
-
-.SS domain master (G)
-
-Enable WAN-wide browse list collation. Local master browsers on
-broadcast-isolated subnets will give samba their local browse lists, and
-ask for a complete copy of the browse list for the whole wide area network.
-Browser clients will then contact their local master browser, and will
-receive the domain-wide browse list, instead of just the list for their
-broadcast-isolated subnet.
-
-.B Default:
- domain master = no
-
-.SS dont descend (S)
-There are certain directories on some systems (eg., the /proc tree under
-Linux) that are either not of interest to clients or are infinitely deep
-(recursive). This parameter allows you to specify a comma-delimited list
-of directories that the server should always show as empty.
-
-Note that Samba can be very fussy about the exact format of the "dont
-descend" entries. For example you may need "./proc" instead of just
-"/proc". Experimentation is the best policy :-)
-
-.B Default:
- none (i.e., all directories are OK to descend)
-
-.B Example:
- dont descend = /proc,/dev
-
-.SS dos filetimes (S)
-Under DOS and Windows, if a user can write to a file they can change
-the timestamp on it. Under POSIX semantics, only the owner of the file
-or root may change the timestamp. By default, Samba runs with POSIX
-semantics and refuses to change the timestamp on a file if the user
-smbd is acting on behalf of is not the file owner. Setting this option
-to True allows DOS semantics and smbd will change the file timstamp as
-DOS requires. This is a correct implementation of a previous compile-time
-options (UTIME_WORKAROUND) which was broken and is now removed.
-
-.B Default:
- dos filetimes = False
-
-.B Example:
- dos filetimes = True
-
-.SS encrypt passwords (G)
-
-This boolean controls whether encrypted passwords will be negotiated
-with the client. Note that this option has no effect if you haven't
-compiled in the necessary des libraries and encryption code. It
-defaults to no.
-
-.SS exec (S)
-
-This is an alias for preexec
-
-.SS fake oplocks (S)
-
-Oplocks are the way that SMB clients get permission from a server to
-locally cache file operations. If a server grants an oplock
-(opportunistic lock) then the client is free to assume that it is the
-only one accessing the file and it will aggressively cache file
-data. With some oplock types the client may even cache file open/close
-operations. This can give enormous performance benefits.
-
-When you set "fake oplocks = yes" Samba will always grant oplock
-requests no matter how many clients are using the file.
-
-By enabling this option on all read-only shares or shares that you know
-will only be accessed from one client at a time you will see a big
-performance improvement on many operations. If you enable this option
-on shares where multiple clients may be accessing the files read-write
-at the same time you can get data corruption. Use this option
-carefully!
-
-It is generally much better to use the real oplock support except for
-physically read-only media such as CDROMs.
-
-This option is disabled by default.
-
-.SS follow symlinks (S)
-
-This parameter allows the Samba administrator to stop smbd from
-following symbolic links in a particular share. Setting this
-parameter to "No" prevents any file or directory that is a
-symbolic link from being followed (the user will get an error).
-This option is very useful to stop users from adding a symbolic
-link to /etc/pasword in their home directory for instance.
-However it will slow filename lookups down slightly.
-
-This option is enabled (ie. smbd will follow symbolic links)
-by default.
-
-.SS force create mode (S)
-This parameter specifies a set of UNIX mode bit permissions that
-will *always* be set on a file created by Samba. This is done
-by bitwise 'OR'ing these bits onto the mode bits of a file that
-is being created. The default for this parameter is (in octel)
-000. The modes in this parameter are bitwise 'OR'ed onto the
-file mode after the mask set in the "create mask" parameter
-is applied.
-
-See also the parameter "create mask" for details on masking mode
-bits on created files.
-
-.B Default:
- force create mode = 000
-
-.B Example:
- force create mode = 0755
-
-would force all created files to have read and execute permissions
-set for 'group' and 'other' as well as the read/write/execute bits
-set for the 'user'.
-
-.SS force directory mode (S)
-This parameter specifies a set of UNIX mode bit permissions that
-will *always* be set on a directory created by Samba. This is done
-by bitwise 'OR'ing these bits onto the mode bits of a directory that
-is being created. The default for this parameter is (in octel)
-0000 which will not add any extra permission bits to a created
-directory. This operation is done after the mode mask in the parameter
-"directory mask" is applied.
-
-See also the parameter "directory mask" for details on masking mode
-bits on created directories.
-
-.B Default:
- force directory mode = 000
-
-.B Example:
- force directory mode = 0755
-
-would force all created directories to have read and execute permissions
-set for 'group' and 'other' as well as the read/write/execute bits
-set for the 'user'.
-
-.SS force group (S)
-This specifies a group name that all connections to this service
-should be made as. This may be useful for sharing files.
-
-.B Default:
- no forced group
-
-.B Example:
- force group = agroup
-
-.SS force user (S)
-This specifies a user name that all connections to this service
-should be made as. This may be useful for sharing files. You should
-also use it carefully as using it incorrectly can cause security
-problems.
-
-This user name only gets used once a connection is established. Thus
-clients still need to connect as a valid user and supply a valid
-password. Once connected, all file operations will be performed as the
-"forced user", not matter what username the client connected as.
-
-.B Default:
- no forced user
-
-.B Example:
- force user = auser
-
-.SS getwd cache (G)
-This is a tuning option. When this is enabled a cacheing algorithm will
-be used to reduce the time taken for getwd() calls. This can have a
-significant impact on performance, especially when widelinks is False.
-
-.B Default:
- getwd cache = No
-
-.B Example:
- getwd cache = Yes
-
-.SS group (S)
-This is an alias for "force group" and is only kept for compatibility
-with old versions of Samba. It may be removed in future versions.
-
-.SS guest account (S)
-This is a username which will be used for access to services which are
-specified as 'guest ok' (see below). Whatever privileges this user has
-will be available to any client connecting to the guest
-service. Typically this user will exist in the password file, but will
-not have a valid login. If a username is specified in a given service,
-the specified username overrides this one.
-
-One some systems the account "nobody" may not be able to print. Use
-another account in this case. You should test this by trying to log in
-as your guest user (perhaps by using the "su \-" command) and trying to
-print using
-.BR lpr .
-
-Note that as of version 1.9 of Samba this option may be set
-differently for each service.
-
-.B Default:
- specified at compile time
-
-.B Example:
- guest account = nobody
-.SS guest ok (S)
-See
-.B public.
-.SS guest only (S)
-If this parameter is 'yes' for a service, then only guest connections to the
-service are permitted. This parameter will have no affect if "guest ok" or
-"public" is not set for the service.
-
-See the section below on user/password validation for more information about
-this option.
-
-.B Default:
- guest only = no
-
-.B Example:
- guest only = yes
-.SS hide dot files (S)
-This is a boolean parameter that controls whether files starting with
-a dot appear as hidden files.
-
-.B Default:
- hide dot files = yes
-
-.B Example:
- hide dot files = no
-
-
-.SS hide files(S)
-This is a list of files or directories that are not visible but are
-accessible. The DOS 'hidden' attribute is applied to any files or
-directories that match.
-
-Each entry in the list must be separated by a "/", which allows spaces
-to be included in the entry. '*' and '?' can be used to specify multiple
-files or directories as in DOS wildcards.
-
-Each entry must be a unix path, not a DOS path and must not include the
-unix directory separator "/".
-
-Note that the case sensitivity option is applicable in hiding files.
-
-Setting this parameter will affect the performance of Samba, as
-it will be forced to check all files and directories for a match
-as they are scanned.
-
-See also "hide dot files", "veto files" and "case sensitive"
-
-.B Default
- No files or directories are hidden by this option (dot files are
- hidden by default because of the "hide dot files" option).
-
-.B Example
- hide files = /.*/DesktopFolderDB/TrashFor%m/resource.frk/
-
-The above example is based on files that the Macintosh client (DAVE)
-creates for internal use, and also still hides all files beginning with
-a dot.
-
-.SS homedir map (G)
-If "nis homedir" is true, this parameter specifies the NIS (or YP) map
-from which the server for the user's home directory should be extracted.
-At present, only the Sun auto.home map format is understood. The form of
-the map is:
-
-username server:/some/file/system
-
-and the program will extract the servername from before the first ':'.
-There should probably be a better parsing system that copes with different
-map formats and also Amd (another automounter) maps.
-
-NB: The -DNETGROUP option is required in the Makefile for option to work
-and on some architectures the line -lrpcsvc needs to be added to the
-LIBSM variable. This is required for Solaris 2, FreeBSD and HPUX.
-
-See also "nis homedir"
-
-.B Default:
- homedir map = auto.home
-
-.B Example:
- homedir map = amd.homedir
-.SS hosts allow (S)
-See
-.B allow hosts.
-.SS hosts deny (S)
-See
-.B deny hosts.
-
-.SS hosts equiv (G)
-If this global parameter is a non-null string, it specifies the name of
-a file to read for the names of hosts and users who will be allowed access
-without specifying a password.
-
-This is not be confused with
-.B allow hosts
-which is about hosts access to services and is more useful for guest services.
-.B hosts equiv
-may be useful for NT clients which will not supply passwords to samba.
-
-NOTE: The use of hosts.equiv can be a major security hole. This is
-because you are trusting the PC to supply the correct username. It is
-very easy to get a PC to supply a false username. I recommend that the
-hosts.equiv option be only used if you really know what you are doing,
-or perhaps on a home network where you trust your wife and kids :-)
-
-.B Default
- No host equivalences
-
-.B Example
- hosts equiv = /etc/hosts.equiv
-
-.SS include (G)
-
-This allows you to include one config file inside another. The file is
-included literally, as though typed in place.
-
-It takes the standard substitutions, except %u, %P and %S
-
-.SS interfaces (G)
-
-This option allows you to setup multiple network interfaces, so that
-Samba can properly handle browsing on all interfaces.
-
-The option takes a list of ip/netmask pairs. The netmask may either be
-a bitmask, or a bitlength.
-
-For example, the following line:
-
-interfaces = 192.168.2.10/24 192.168.3.10/24
-
-would configure two network interfaces with IP addresses 192.168.2.10
-and 192.168.3.10. The netmasks of both interfaces would be set to
-255.255.255.0.
-
-You could produce an equivalent result by using:
-
-interfaces = 192.168.2.10/255.255.255.0 192.168.3.10/255.255.255.0
-
-if you prefer that format.
-
-If this option is not set then Samba will attempt to find a primary
-interface, but won't attempt to configure more than one interface.
-
-.SS invalid users (S)
-This is a list of users that should not be allowed to login to this
-service. This is really a "paranoid" check to absolutely ensure an
-improper setting does not breach your security.
-
-A name starting with @ is interpreted as a UNIX group.
-
-The current servicename is substituted for %S. This is useful in the
-[homes] section.
-
-See also "valid users"
-
-.B Default
- No invalid users
-
-.B Example
- invalid users = root fred admin @wheel
-
-.SS keep alive (G)
-The value of the parameter (an integer) represents the number of seconds
-between 'keepalive' packets. If this parameter is zero, no keepalive packets
-will be sent. Keepalive packets, if sent, allow the server to tell whether a
-client is still present and responding.
-
-Keepalives should, in general, not be needed if the socket being used
-has the SO_KEEPALIVE attribute set on it (see "socket
-options"). Basically you should only use this option if you strike
-difficulties.
-
-.B Default:
- keep alive = 0
-
-.B Example:
- keep alive = 60
-.SS load printers (G)
-A boolean variable that controls whether all printers in the printcap
-will be loaded for browsing by default.
-
-.B Default:
- load printers = yes
-
-.B Example:
- load printers = no
-
-.SS local master (G)
-This option allows the nmbd to become a local master browser on a
-subnet. If set to False then nmbd will not attempt to become a local
-master browser on a subnet and will also lose in all browsing elections.
-By default this value is set to true. Setting this value to true doesn't
-mean that Samba will become the local master browser on a subnet, just
-that the nmbd will participate in elections for local master browser.
-
-.B Default:
- local master = yes
-
-.SS lock directory (G)
-This option specifies the directory where lock files will be placed.
-The lock files are used to implement the "max connections" option.
-
-.B Default:
- lock directory = /tmp/samba
-
-.B Example:
- lock directory = /usr/local/samba/var/locks
-
-.SS locking (S)
-This controls whether or not locking will be performed by the server in
-response to lock requests from the client.
-
-If "locking = no", all lock and unlock requests will appear to succeed and
-all lock queries will indicate that the queried lock is clear.
-
-If "locking = yes", real locking will be performed by the server.
-
-This option may be particularly useful for read-only filesystems which
-do not need locking (such as cdrom drives).
-
-Be careful about disabling locking either globally or in a specific
-service, as lack of locking may result in data corruption.
-
-.B Default:
- locking = yes
-
-.B Example:
- locking = no
-
-.SS log file (G)
-
-This options allows you to override the name of the Samba log file
-(also known as the debug file).
-
-This option takes the standard substitutions, allowing you to have
-separate log files for each user or machine.
-
-.B Example:
- log file = /usr/local/samba/var/log.%m
-
-.SS log level (G)
-see "debug level"
-
-.SS logon drive (G)
-
-This parameter specifies the local path to which the home directory
-will be connected (see "logon home") and is only used by NT Workstations.
-
-.B Example:
- logon drive = h:
-
-.SS logon home (G)
-
-This parameter specifies the home directory location when a Win95 or
-NT Workstation logs into a Samba PDC. It allows you to do "NET USE
-H: /HOME" from a command prompt, for example.
-
-.B
-This option takes the standard substitutions, allowing you to have
-separate logon scripts for each user or machine.
-
-.B Example:
- logon home = "\\\\remote_smb_server\\%U"
-
-.B Default:
- logon home = "\\\\%N\\%U"
-
-.SS logon path (G)
-
-This parameter specifies the home directory where roaming profiles
-(USER.DAT / USER.MAN files for Windows 95) are stored.
-
-This option takes the standard substitutions, allowing you to have
-separate logon scripts for each user or machine. It also specifies
-the directory from which the "desktop", "start menu", "nethood" and
-"programs" folders, and their contents, are loaded and displayed
-on your Windows 95 client.
-
-The share and the path must be readable by the user for the preferences
-and directories to be loaded onto the Windows 95 client. The share
-must be writeable when the logs in for the first time, in order that
-the Windows 95 client can create the user.dat and other directories.
-
-Thereafter, the directories and any of contents can, if required,
-be made read-only. It is not adviseable that the USER.DAT file be made
-read-only - rename it to USER.MAN to achieve the desired effect
-(a MANdatory profile).
-
-Windows clients can sometimes maintain a connection to the [homes]
-share, even though there is no user logged in. Therefore, it is
-vital that the logon path does not include a reference to the
-homes share (i.e \\\\%N\\HOMES\profile_path will cause problems).
-
-.B
-This option takes the standard substitutions, allowing you to have
-separate logon scripts for each user or machine.
-
-.B Default:
- logon path = \\\\%N\\%U\\profile
-
-.B Example:
- logon path = \\\\PROFILESERVER\\HOME_DIR\\%U\\PROFILE
-
-.SS logon script (G)
-
-This parameter specifies the batch file (.bat) or NT command file (.cmd)
-to be downloaded and run on a machine when a user successfully logs in.
-The file must contain the DOS style cr/lf line endings. Using a DOS-style
-editor to create the file is recommended.
-
-The script must be a relative path to the [netlogon] service. If the
-[netlogon] service specifies a path of /usr/local/samba/netlogon, and
-logon script = STARTUP.BAT, then file that will be downloaded is:
-
-.B /usr/local/samba/netlogon/STARTUP.BAT
-
-The contents of the batch file is entirely your choice. A suggested
-command would be to add NET TIME \\\\SERVER /SET /YES, to force every
-machine to synchronise clocks with the same time server. Another use
-would be to add NET USE U: \\\\SERVER\\UTILS for commonly used utilities,
-or NET USE Q: \\\\SERVER\\ISO9001_QA.
-
-Note that it is particularly important not to allow write access to
-the [netlogon] share, or to grant users write permission on the
-batch files in a secure environment, as this would allow the batch
-files to be arbitrarily modified.
-
-.B
-This option takes the standard substitutions, allowing you to have
-separate logon scripts for each user or machine.
-
-.B Example:
- logon script = scripts/%U.bat
-
-.SS lppause command (S)
-This parameter specifies the command to be executed on the server host in
-order to stop printing or spooling a specific print job.
-
-This command should be a program or script which takes a printer name and
-job number to pause the print job. Currently I don't know of any print
-spooler system that can do this with a simple option, except for the PPR
-system from Trinity College (ppr\-dist.trincoll.edu/pub/ppr). One way
-of implementing this is by using job priorities, where jobs having a too
-low priority won't be sent to the printer. See also the
-.B lppause
-command.
-
-If a %p is given then the printername is put in its place. A %j is
-replaced with the job number (an integer).
-On HPUX (see printing=hpux), if the -p%p option is added to the lpq
-command, the job will show up with the correct status, i.e. if the job
-priority is lower than the set fence priority it will have the PAUSED
-status, whereas if the priority is equal or higher it will have the
-SPOOLED or PRINTING status.
-
-Note that it is good practice to include the absolute path in the lppause
-command as the PATH may not be available to the server.
-
-.B Default:
- Currently no default value is given to this string
-
-.B Example for HPUX:
- lppause command = /usr/bin/lpalt %p-%j -p0
-
-.SS lpq cache time (G)
-
-This controls how long lpq info will be cached for to prevent the lpq
-command being called too often. A separate cache is kept for each
-variation of the lpq command used by the system, so if you use
-different lpq commands for different users then they won't share cache
-information.
-
-The cache files are stored in /tmp/lpq.xxxx where xxxx is a hash
-of the lpq command in use.
-
-The default is 10 seconds, meaning that the cached results of a
-previous identical lpq command will be used if the cached data is less
-than 10 seconds old. A large value may be advisable if your lpq
-command is very slow.
-
-A value of 0 will disable cacheing completely.
-
-.B Default:
- lpq cache time = 10
-
-.B Example:
- lpq cache time = 30
-
-.SS lpq command (S)
-This parameter specifies the command to be executed on the server host in
-order to obtain "lpq"-style printer status information.
-
-This command should be a program or script which takes a printer name
-as its only parameter and outputs printer status information.
-
-Currently six styles of printer status information are supported; BSD,
-SYSV, AIX, HPUX, QNX, LPRNG and PLP. This covers most UNIX systems. You
-control which type is expected using the "printing =" option.
-
-Some clients (notably Windows for Workgroups) may not correctly send the
-connection number for the printer they are requesting status information
-about. To get around this, the server reports on the first printer service
-connected to by the client. This only happens if the connection number sent
-is invalid.
-
-If a %p is given then the printername is put in its place. Otherwise
-it is placed at the end of the command.
-
-Note that it is good practice to include the absolute path in the lpq
-command as the PATH may not be available to the server.
-
-.B Default:
- depends on the setting of "printing ="
-
-.B Example:
- lpq command = /usr/bin/lpq %p
-
-.SS lpresume command (S)
-This parameter specifies the command to be executed on the server host in
-order to restart or continue printing or spooling a specific print job.
-
-This command should be a program or script which takes a printer name and
-job number to resume the print job. See also the lppause command.

+.IP
+This is the full pathname to a script that will be run \fIAS ROOT\fP by
+\fBsmbd (8)\fP under special circumstances decribed
+below\&.
+.IP
+Normally, a Samba server requires that UNIX users are created for all
+users accessing files on this server\&. For sites that use Windows NT
+account databases as their primary user database creating these users
+and keeping the user list in sync with the Windows NT PDC is an
+onerous task\&. This option allows \fBsmbd\fP to delete
+the required UNIX users \fION DEMAND\fP when a user accesses the Samba
+server and the Windows NT user no longer exists\&.
+.IP
+In order to use this option, \fBsmbd\fP must be set to

+on an attempted user logon that a user no longer exists\&. In the
+\fBsecurity=server\fP mode a missing user
+is treated the same as an invalid password logon attempt\&. Deleting
+the user in this circumstance would not be a good idea\&.
+.IP
+When the Windows user attempts to access the Samba server, at
+\fI"login"\fP(session setup in the SMB protocol) time,
+\fBsmbd\fP contacts the \fBpassword

+This option is mainly used as a compatibility option for Visual C++

+.IP
+NTFS and Windows VFAT file systems keep a create time for all files
+and directories\&. This is not the same as the ctime - status change
+time - that Unix keeps, so Samba by default reports the earliest of
+the various times Unix does keep\&. Setting this parameter for a share
+causes Samba to always report midnight 1-1-1980 as the create time for
+directories\&.
+.IP
+This option is mainly used as a compatibility option for Visual C++
+when used against Samba shares\&. Visual C++ generated makefiles have
+the object directory as a dependency for each object file, and a make
+rule to create the directory\&. Also, when NMAKE compares timestamps it
+uses the creation time when examining a directory\&. Thus the object
+directory will be created if it does not exist, but once it does exist
+it will always have an earlier timestamp than the object files it
+contains\&.
+.IP
+However, Unix time semantics mean that the create time reported by
+Samba will be updated whenever a file is created or deleted in the
+directory\&. NMAKE therefore finds all object files in the object
+directory bar the last one built are out of date compared to the
+directory and rebuilds them\&. Enabling this option ensures directories
+always predate their contents and an NMAKE build will proceed as
+expected\&.

+.IP
+Oplocks are the way that SMB clients get permission from a server to
+locally cache file operations\&. If a server grants an oplock
+(opportunistic lock) then the client is free to assume that it is the
+only one accessing the file and it will aggressively cache file
+data\&. With some oplock types the client may even cache file open/close
+operations\&. This can give enormous performance benefits\&.
+.IP
+When you set \f(CW"fake oplocks = yes"\fP \fBsmbd\fP will
+always grant oplock requests no matter how many clients are using the
+file\&.
+.IP
+It is generally much better to use the real \fBoplocks\fP
+support rather than this parameter\&.
+.IP
+If you enable this option on all read-only shares or shares that you
+know will only be accessed from one client at a time such as
+physically read-only media like CDROMs, you will see a big performance
+improvement on many operations\&. If you enable this option on shares
+where multiple clients may be accessing the files read-write at the
+same time you can get data corruption\&. Use this option carefully!

+or directory that is a symbolic link from being followed (the user
+will get an error)\&. This option is very useful to stop users from
+adding a symbolic link to \f(CW/etc/passwd\fP in their home directory for

+This specifies a UNIX group name that will be assigned as the default

+files\&.
+.IP
+In Samba 2\&.0\&.5 and above this parameter has extended functionality in the following
+way\&. If the group name listed here has a \'+\' character prepended to it
+then the current user accessing the share only has the primary group
+default assigned to this group if they are already assigned as a member
+of that group\&. This allows an administrator to decide that only users
+who are already in a particular group will create files with group
+ownership set to that group\&. This gives a finer granularity of ownership
+assignment\&. For example, the setting \f(CWforce group = +sys\fP means

+Level2, or read-only oplocks allow Windows NT clients that have an
+oplock on a file to downgrade from a read-write oplock to a read-only
+oplock once a second client opens the file (instead of releasing all
+oplocks on a second open, as in traditional, exclusive oplocks)\&. This
+allows all openers of the file that support level2 oplocks to cache
+the file for read-ahead only (ie\&. they may not cache writes or lock
+requests) and increases performance for many acesses of files that
+are not commonly written (such as application \&.EXE files)\&.
+.IP
+Once one of the clients which have a read-only oplock writes to
+the file all clients are notified (no reply is needed or waited

If mangling is used then the mangling algorithm is as follows:
-.RS
-- the first (up to) five alphanumeric characters before the rightmost dot of
-the filename are preserved, forced to upper case, and appear as the first (up
-to) five characters of the mangled name.
-
-- a tilde ("~") is appended to the first part of the mangled name, followed
-by a two-character unique sequence, based on the original root name
-(i.e., the original filename minus its final extension). The final
-extension is included in the hash calculation only if it contains any upper
-case characters or is longer than three characters.
-
-Note that the character to use may be specified using the "mangling
-char" option, if you don't like ~.
-
-- the first three alphanumeric characters of the final extension are preserved,
-forced to upper case and appear as the extension of the mangled name. The
-final extension is defined as that part of the original filename after the
-rightmost dot. If there are no dots in the filename, the mangled name will
-have no extension (except in the case of hidden files - see below).
-
-- files whose UNIX name begins with a dot will be presented as DOS hidden
-files. The mangled name will be created as for other filenames, but with the
-leading dot removed and "___" as its extension regardless of actual original
-extension (that's three underscores).
-.RE
-
-The two-digit hash value consists of upper case alphanumeric characters.
-
-This algorithm can cause name collisions only if files in a directory share
-the same first five alphanumeric characters. The probability of such a clash
-is 1/1300.

+protocol when in \fB"security=server"\fP mode
+and cannot be fixed in Samba\&.
+.IP
+.IP o
+If you are using a Windows NT server as your password server then
+you will have to ensure that your users are able to login from the

-
-.SS print command (S)
-After a print job has finished spooling to a service, this command will be
-used via a system() call to process the spool file. Typically the command
-specified will submit the spool file to the host's printing subsystem, but
-there is no requirement that this be the case. The server will not remove the
-spool file, so whatever command you specify should remove the spool file when
-it has been processed, otherwise you will need to manually remove old spool
-files.
-
-The print command is simply a text string. It will be used verbatim,
-with two exceptions: All occurrences of "%s" will be replaced by the
-appropriate spool file name, and all occurrences of "%p" will be
-replaced by the appropriate printer name. The spool file name is
-generated automatically by the server, the printer name is discussed
-below.
-
-The full path name will be used for the filename if %s is not preceded
-by a /. If you don't like this (it can stuff up some lpq output) then
-use %f instead. Any occurrences of %f get replaced by the spool
-filename without the full path at the front.
-
-The print command MUST contain at least one occurrence of "%s" or %f -
-the "%p" is optional. At the time a job is submitted, if no printer
-name is supplied the "%p" will be silently removed from the printer
-command.
-
-If specified in the [global] section, the print command given will be used
-for any printable service that does not have its own print command specified.
-
-If there is neither a specified print command for a printable service nor a
-global print command, spool files will be created but not processed and (most
-importantly) not removed.
-
-Note that printing may fail on some UNIXes from the "nobody"
-account. If this happens then create an alternative guest account that
-can print and set the "guest account" in the [global] section.
-
-You can form quite complex print commands by realising that they are
-just passed to a shell. For example the following will log a print
-job, print the file, then remove it. Note that ; is the usual
-separator for command in shell scripts.
-
-print command = echo Printing %s >> /tmp/print.log; lpr -P %p %s; rm %s
-
-You may have to vary this command considerably depending on how you
-normally print files on your system.
-
-.B Default:
- print command = lpr -r -P %p %s
-
-.B Example:
- print command = /usr/local/samba/bin/myprintscript %p %s
-.SS print ok (S)
-See
-.B printable.
-.SS printable (S)
-A synonym for this parameter is 'print ok'.
-
-If this parameter is 'yes', then clients may open, write to and submit spool
-files on the directory specified for the service.
-
-Note that a printable service will ALWAYS allow writing to the service path
-(user privileges permitting) via the spooling of print data. The 'read only'
-parameter controls only non-printing access to the resource.
-
-.B Default:
- printable = no
-
-.B Example:
- printable = yes
-
-.SS printcap name (G)
-This parameter may be used to override the compiled-in default printcap
-name used by the server (usually /etc/printcap). See the discussion of the
-[printers] section above for reasons why you might want to do this.
-
-For those of you without a printcap (say on SysV) you can just create a
-minimal file that looks like a printcap and set "printcap name =" in
-[global] to point at it.
-
-A minimal printcap file would look something like this:
-
-print1|My Printer 1
-.br
-print2|My Printer 2
-.br
-print3|My Printer 3
-.br
-print4|My Printer 4
-.br
-print5|My Printer 5
-
-where the | separates aliases of a printer. The fact that the second
-alias has a space in it gives a hint to Samba that it's a comment.
-
-NOTE: Under AIX the default printcap name is "/etc/qconfig". Samba
-will assume the file is in AIX "qconfig" format if the string
-"/qconfig" appears in the printcap filename.
-
-.B Default:
- printcap name = /etc/printcap
-
-.B Example:
- printcap name = /etc/myprintcap
-.SS printer (S)

-.SH NOTE ABOUT USERNAME/PASSWORD VALIDATION
-There are a number of ways in which a user can connect to a
-service. The server follows the following steps in determining if it
-will allow a connection to a specified service. If all the steps fail
-then the connection request is rejected. If one of the steps pass then
-the following steps are not checked.
-
-If the service is marked "guest only = yes" then steps 1 to 5 are skipped
-
-Step 1: If the client has passed a username/password pair and that
-username/password pair is validated by the UNIX system's password
-programs then the connection is made as that username. Note that this
-includes the \e\eserver\eservice%username method of passing a username.
-
-Step 2: If the client has previously registered a username with the
-system and now supplies a correct password for that username then the
-connection is allowed.
-
-Step 3: The client's netbios name and any previously used user names
-are checked against the supplied password, if they match then the
-connection is allowed as the corresponding user.
-
-Step 4: If the client has previously validated a username/password
-pair with the server and the client has passed the validation token
-then that username is used. This step is skipped if "revalidate = yes"
-for this service.
-
-Step 5: If a "user = " field is given in the smb.conf file for the
-service and the client has supplied a password, and that password
-matches (according to the UNIX system's password checking) with one of
-the usernames from the user= field then the connection is made as the
-username in the "user=" line. If one of the username in the user= list
-begins with a @ then that name expands to a list of names in the group
-of the same name.
-
-Step 6: If the service is a guest service then a connection is made as
-the username given in the "guest account =" for the service,
-irrespective of the supplied password.
-.SH WARNINGS
-Although the configuration file permits service names to contain spaces,
-your client software may not. Spaces will be ignored in comparisons anyway,
-so it shouldn't be a problem - but be aware of the possibility.
-
-On a similar note, many clients - especially DOS clients - limit service
-names to eight characters. Smbd has no such limitation, but attempts
-to connect from such clients will fail if they truncate the service names.
-For this reason you should probably keep your service names down to eight
-characters in length.
-
-Use of the [homes] and [printers] special sections make life for an
-administrator easy, but the various combinations of default attributes can be
-tricky. Take extreme care when designing these sections. In particular,
-ensure that the permissions on spool directories are correct.
-.SH VERSION
-This man page is (mostly) correct for version 1.9.18 of the Samba suite, plus some
-of the recent patches to it. These notes will necessarily lag behind
-development of the software, so it is possible that your version of
-the server has extensions or parameter semantics that differ from or are not
-covered by this man page. Please notify these to the address below for
-rectification.
-
-Prior to version 1.5.21 of the Samba suite, the configuration file was
-radically different (more primitive). If you are using a version earlier than
-1.8.05, it is STRONGLY recommended that you upgrade.

-.SH DIAGNOSTICS
-[This section under construction]
-
-Most diagnostics issued by the server are logged in a specified log file. The
-log file name is specified at compile time, but may be overridden on the
-smbd command line (see
-.BR smbd (8)).
-
-The number and nature of diagnostics available depends on the debug level used
-by the server. If you have problems, set the debug level to 3 and peruse the
-log files.
-
-Most messages are reasonably self-explanatory. Unfortunately, at time of
-creation of this man page the source code is still too fluid to warrant
-describing each and every diagnostic. At this stage your best bet is still
-to grep the source code and inspect the conditions that gave rise to the
-diagnostics you are seeing.
