By default (when run with no arguments) it will attempt to change the
current users SMB password on the local machine. This is similar to
-the way the bf(passwd (1)) program works. Note that in order for this

+the bf(passwd) program works however in that it is not em(setuid root)
+but works in a client-server mode and communicates with a locally
+running url(bf(smbd))(smbd.8.html). As a consequence in order for this
to succeed the url(bf(smbd))(smbd.8.html) daemon must be running on
the local machine. On a UNIX machine the encrypted SMB passwords are
usually stored in the url(bf(smbpasswd (5)))(smbpasswd.5.html) file.
bf(smbpasswd) also can be used by a normal user to change their SMB
password on remote machines, such as Windows NT Primary Domain

be added to the local url(bf(smbpasswd))(smbpasswd.5.html) file, with
the new password typed (type <Enter> for the old password). This

em(enabled) in the local url(bf(smbpasswd))(smbpasswd.5.html) file,
if the account was previously disabled. If the account was not
designed for use only by developers and generate HUGE amounts of log
data, most of which is extremely cryptic.
+label(minusn)
dit(bf(-n)) This option specifies that the username following should
have their password set to null (i.e. a blank password) in the local
url(bf(smbpasswd))(smbpasswd.5.html) file. This is done by writing the
the following parameter in the [global] section of the
url(bf(smb.conf))(smb.conf.5.html) file :
-url(null passwords = true)(smb.conf.5.html#null passwords)
+url(null passwords = true)(smb.conf.5.html#nullpasswords)
This option is only available when running bf(smbpasswd) as root.
-dit(bf(-r remote machine name)) This option allows a user to specify
-what machine they wish to change their password on. Without this
-parameter bf(smbpasswd) defaults to the local host. The em("remote
-machine name") is the NetBIOS name of the SMB/CIFS server to contact
-to attempt the password change. This name is resolved into an IP
-address using the standard name resolution mechanism in all programs
-of the url(bf(Samba))(samba.7.html) suite. See the link(bf(-R name
-resolve order))(nameresolveorder) parameter for details on changing this
-resolving mechanism.
+label(minusr)
+dit(bf(-r remote machine name)) This option allows a
+user to specify what machine they wish to change their password
+on. Without this parameter bf(smbpasswd) defaults to the local

Note that if changing a Windows NT Domain password the remote machine
specified must be the Primary Domain Controller for the domain (Backup
Domain Controllers only have a read-only copy of the user account
database and will not allow the password change).

dit(bf(-R name resolve order)) This option allows the user of
smbclient to determine what name resolution services to use when
looking up the NetBIOS name of the host being connected to.
-The options are :"lmhosts", "host", "wins" and "bcast". They cause
-names to be resolved as follows :

using the system /etc/hosts, NIS, or DNS lookups. This method of name
resolution is operating system depended for instance on IRIX or
Solaris this may be controlled by the em(/etc/nsswitch.conf) file).

no WINS server has been specified this method will be ignored.

it() bf(bcast) : Do a broadcast on each of the known local interfaces
listed in the url(bf(interfaces))(smb.conf.5.html#interfaces) parameter
in the smb.conf file. This is the least reliable of the name resolution
If this parameter is not set then the name resolver order defined
in the url(bf(smb.conf))(smb.conf.5.html) file parameter
-url((bf(name resolve order))(smb.conf.5.html#name resolve order)
+url(bf(name resolve order))(smb.conf.5.html#nameresolveorder)
will be used.
The default order is lmhosts, host, wins, bcast and without this
parameter or any entry in the url(bf(smb.conf))(smb.conf.5.html)
file the name resolution methods will be attempted in this order.

dit(bf(-m)) This option tells bf(smbpasswd) that the account being
changed is a em(MACHINE) account. Currently this is used when Samba is
being used as an NT Primary Domain Controller. PDC support is not a

dit(bf(-j DOMAIN)) This option is used to add a Samba server into a
Windows NT Domain, as a Domain member capable of authenticating user
accounts to any Domain Controller in the same way as a Windows NT
In order to be used in this way, the Administrator for the Windows
NT Domain must have used the program em("Server Manager for Domains")

After this has been done, to join the Domain invoke bf(smbpasswd) with

Controller for the Domain (found in the
url(bf(smb.conf))(smb.conf.5.html) file in the parameter
-url(bf("password server"))(smb.conf.5.html#password server) and change

the machine account password used to create the secure Domain
communication. This password is then stored by bf(smbpasswd) in a

-.B New for 1.9.18p4.
-smbpasswd will now allow a user to change their password
-on a Windows NT server. To use this add the
-.I \-r
-.I \<remote_machine\>
-paramter to the smbpasswd command. The machine name is looked
-up using the "name resolve order" parameter defined in the
-smb.conf [global] section. Note that when changing a Windows
-NT password for a domain user,
-.I \<remote machine\>
-must be the name of the Primary domain controller.
-
-To allow users to change their passwords from "NO PASSWORD" in the
-smbpasswd file to a valid password the administrator must set the
-following parameter in the [global] section of the smb.conf :
-
-null passwords = true
-
-This is .B NOT recommended as a general policy, it is recommended that
-new users be assigned a default password instead.

-
-The location of the server and its support files is a matter for individual
-system administrators. The following are thus suggestions only.
-
-It is recommended that the
-.B smbpasswd
-program be installed in the /usr/local/samba/bin directory. This should be
-a directory readable by all, writeable only by root. The program should be
-executable by all. The program
-.B must not

-.SH VERSION
-
-This man page is correct for version 1.9.18p4 of the Samba suite.
-These notes will necessarily lag behind
-development of the software, so it is possible that your version of
-the program has extensions or parameter semantics that differ from or are not

+
+As bf(smbpasswd) works in client-server mode communicating with a
+local url(bf(smbd))(smbd.8.html) for a non-root user then the bf(smbd)
+daemon must be running for this to work. A common problem is to add a
+restriction to the hosts that may access the bf(smbd) running on the
+local machine by specifying a url(bf("allow
+hosts"))(smb.conf.5.html#allowhosts) or url(bf("deny
+hosts"))(smb.conf.5.html#denyhosts) entry in the
+url(bf(smb.conf))(smb.conf.5.html) file and neglecting to allow
+em("localhost") access to the bf(smbd).
+
+In addition, the bf(smbpasswd) command is only useful if bf(Samba) has
+been set up to use encrypted passwords. See the file bf(ENCRYPTION.txt)
in the docs directory for details on how to do this.
