- WHATS NEW IN Samba 3.0 alpha23
- 30th March 2003
+ =============================
+ Release Notes for Samba 3.0.6
+ Aug 19, 2004
+ =============================
+
+This is the latest stable release of Samba. This is the version
+that production Samba servers should be running for all
+current bug-fixes. There have been several issues fixes since
+the 3.0.4/5 release and new features have been added as well.
+See the "Changes" section for details on exact updates.
+
+Common bugs fixed in 3.0.6 include:
+
+ o Schannel failure in winbindd.
+ o Numerous memory leaks.
+ o Incompatibilities between the 'write list' and 'force user'
+ smb.conf options.
+ o Premature optimization of the open_directory() internal
+ function that broke tools such as the ArcServe backup
+ agent, Macromedia HomeSite, and Robocopy.
+ o Corrupt workgroup names in nmbd's browse.dat.
+ o Sharing violation errors commonly seen when opening
+ when serving Microsoft Office documents from a Samba
+ file share.
+ o Browsing problems caused by an apostrophe (') in the
+ computer's description field.
+ o Problems creating special file types from UNIX CIFS
+ clients and enabling 'unix extensions'.
+ o Fix stalls in smbd caused by inaccessible LDAP servers.
+ o Remove various memory leaks.
+ o Fix issues in the password lockout feature.
+
+New features introduced in this release include:
+
+ O Support symlinks created by CIFS clients which
+ can be followed on the server.
+ o Using a cups server other than localhost.
+ o Maintaining the service principal entry in the system
+ keytab for integration with other kerberized services.
+ Please refer to the 'use kerberos keytab' entry in
+ smb.conf(5). When using the heimdal kerberos libraries,
+ you must also specify the following in /etc/krb5.conf:
+ [libdefaults]
+ default_keytab_name = FILE:/etc/krb5.keytab
+ o Support for maintaining individual printer names
+ stored separately from the printer's sharename.
+ o Support for maintaining user password history.
+ o Support for honoring the logon times for user in a
+ Samba domain.
+
+--------------------------------------------
+unix extensions = yes (default) and symlinks
+--------------------------------------------
+
+Beginning with Samba 3.0.6pre1 (formerly known as 3.0.5pre1),
+clients supporting the UNIX extensions to the CIFS protocol
+can create symlinks to absolute paths which will be **followed**
+by the server. This functionality has been requested in order
+to correctly support certain applications when the user's home
+directory is mounted using some type of CIFS client (e.g. the
+cifsvfs in the Linux 2.6 kernel).
+
+If this behavior is not acceptable for your production environment
+you can set 'wide links = no' in the specific share declaration in
+the server's smb.conf. Be aware that disabling wide link support
+out of a share in Samba may impact the server's performance due
+to the fact that smbd will now have to check each path additional
+times before traversing it.
+
+------------------------
+Password History Support
+------------------------
+
+The new password history feature allows smbd to check the new
+password in password change requests against a list of the user's
+previous passwords. The number of previous passwords to save can
+be set using pdbedit (4 in this example):
+
+ root# pdbedit -P "password history" -C 4
+
+When using the ldapsam passdb backend, it is vital to secure the
+following attributes from access by non-administrative users:
+
+ * sambaNTPassword
+ * sambaLMPassword
+ * sambaPasswordHistory
+
+You should refer to your directory server's documentation on how
+to implement this restriction.

+ in the main list but append it manually for the relevant searches.
+ * Fix two memleaks in login_cache.c.
+ * fixes memory bloat when unmarshalling strings.

+ =============================
+ Release Notes for Samba 3.0.5
+ July 20, 2004
+ =============================
+
+Please note that Samba 3.0.5 is identical to Samba 3.0.4 with
+the exception of correcting the two security issues outlined
+below.
+
+######################## SECURITY RELEASE ########################
+
+Summary: Multiple Potential Buffer Overruns in Samba 3.0.x
+CVE ID: CAN-2004-0600, CAN-2004-0686
+ (http://cve.mitre.org/)
+
+
+This is the latest stable release of Samba. This is the version
+that production Samba servers should be running for all current
+bug-fixes.
+
+It has been confirmed that versions of Samba 3 prior to v3.0.4
+are vulnerable to two potential buffer overruns. The individual
+details are given below.
+
+-------------
+CAN-2004-0600
+-------------
+
+Affected Versions: Samba 3.0.2 and later
+
+The internal routine used by the Samba Web Administration
+Tool (SWAT v3.0.2 and later) to decode the base64 data
+during HTTP basic authentication is subject to a buffer
+overrun caused by an invalid base64 character. It is
+recommended that all Samba v3.0.2 or later installations
+running SWAT either (a) upgrade to v3.0.5, or (b) disable
+the swat administration service as a temporary workaround.
+
+This same code is used internally to decode the
+sambaMungedDial attribute value when using the ldapsam
+passdb backend. While we do not believe that the base64
+decoding routines used by the ldapsam passdb backend can
+be exploited, sites using an LDAP directory service with
+Samba are strongly encouraged to verify that the DIT only
+allows write access to sambaSamAccount attributes by a
+sufficiently authorized user.
+
+The Samba Team would like to heartily thank Evgeny Demidov
+for analyzing and reporting this bug.
+
+-------------
+CAN-2004-0686
+-------------
+
+Affected Versions: Samba 3.0.0 and later
+
+A buffer overrun has been located in the code used to support
+the 'mangling method = hash' smb.conf option. Please be aware
+that the default setting for this parameter is 'mangling method
+= hash2' and therefore not vulnerable.
+
+Affected Samba 3 installations can avoid this possible security
+bug by using the default hash2 mangling method. Server
+installations requiring the hash mangling method are encouraged
+to upgrade to Samba 3.0.5.

+ ==============================
+ Release Notes for Samba 3.0.2a
+ February 13, 2004
==============================
-This is a pre-release of Samba 3.0. This is NOT a stable release.
-Use at your own risk.
+Samba 3.0.2a is a minor patch release for the 3.0.2 code base
+to address, in particular, a problem when using pdbedit to
+sanitize (--force-initialized-passwords) Samba's tdbsam
+backend. This is the latest stable release of Samba. This
+is the version that all production Samba servers should be
+running for all current bug-fixes.
-The purpose of this alpha release is to get wider testing of the major
-new pieces of code in the current Samba 3.0 development tree. We have
-officially ceased development on the 2.2.x release of Samba and are
-concentrating on Samba 3.0. To reduce the time before the final Samba 3.0
-release we need as many people as possible to start testing these alpha
-releases, and hopefully giving us some high quality feedback on what needs
-fixing.
+******************* Attention! Achtung! Kree! *********************
-Note that Samba 3.0 is not feature complete yet. There is a more
-coding we have planned, but unless we get what we have done already more
-widely tested we will have a hard time doing a stable release in a
-reasonable time frame.
+Beginning with Samba 3.0.2, passwords for accounts with a last
+change time (LCT-XXX in smbpasswd, sambaPwdLastSet attribute in
+ldapsam, etc...) of zero (0) will be regarded as uninitialized
+strings. This will cause authentication to fail for such
+accounts. If you have valid passwords that meet this criteria,
+you must update the last change time to a non-zero value. If you
+do not, then 'pdbedit --force-initialized-passwords' will disable
+these accounts and reset the password hashes to a string of X's.
-Major new features:
+******************* Attention! Achtung! Kree! *********************
+
+
+Changes since 3.0.2
-------------------
-- Active Directory support. This release is able to join a ADS realm
- as a member server and authenticate users using LDAP/kerberos.
+commits
+-------
-- Unicode support. Samba will now negotiate UNICODE on the wire and
- internally there is now a much better infrastructure for multi-byte
- and UNICODE character sets.
+Please refer to the CVS log for the SAMBA_3_0 branch for complete
+details. The list of changes per contributor are as follows:
-- New authentication system. The internal authentication system has
- been almost completely rewritten. Most of the changes are internal,
- but the new auth system is also very configurable.
-- new filename mangling system. The filename mangling system has been
- completely rewritten. An internal database now stores mangling maps
- persistently. This needs lots of testing.
+o Jeremy Allison <jra@samba.org>
+ * Added paranoia checks in parsing code.
+
-- new "net" command. A new "net" command has been added. It is
- somewhat similar to the "net" command in windows. Eventually we plan
- to replace a bunch of other utilities (such as smbpasswd) with
- subcommands in "net", at the moment only a few things are
- implemented.
+o Andrew Bartlett <abartlet@samba.org>
+ * Ensure that changes to uninitialized passwords in ldapsam
+ are written to the DIT.
-- Samba now negotiates NT-style status32 codes on the wire. This
- improves error handling a lot.
-- better w2k printing support including publishing printer
- attributes in active directory
+o Gerald (Jerry) Carter <jerry@samba.org>
+ * Fixed iterator in tdbsam.
+ * Fix bug that disabled accounts with a valid NT password
+ hash, but no LanMan hash.
+
-- new loadable RPC modules
+o Steve French <sfrench@us.ibm.com>
+ * Added missing nosetuid and noexec options.
-- new dual-daemon winbindd support for better performance
+
+o Bostjan Golob <golob@gimb.org>
+ * BUG 1046: Don't overwrite usernames of entries returned
+ by getpwent_list().
-- support for migrating from a Windows NT 4.0 domain
-- support for establishing trust relationships with Windows NT 4.0
- domain controllers
+o Sebastian Krahmer <krahmer@suse.de>
+ * Fixed potential crash bug in NTLMSSP parsing code.
-Plus lots of other changes!
+o Tim Potter <tpot@samba.org>
+ * Fixed logic in tdb_brlock error checking.
-Reporting bugs & Development Discussion
----------------------------------------
+
+o Urban Widmark <urban@teststation.com>
+ * Set nosuid,nodev flags in smbmnt by default.
+
+
+ --------------------------------------------------
+
+ =============================
+ Release Notes for Samba 3.0.2
+ February 9, 2004
+ =============================
-Please discuss this release on the samba-technical mailing list or by
-joining the #samba-technical IRC channel on irc.freenode.net.
+It has been confirmed that previous versions of Samba 3.0 are
+susceptible to a password initialization bug that could grant an
+attacker unauthorized access to a user account created by the
+mksmbpasswd.sh shell script.
-If you do report problems then please try to send high quality
-feedback. If you don't provide vital information to help us track down
-the problem then you will probably be ignored.
+The Common Vulnerabilities and Exposures project (cve.mitre.org)
+has assigned the name CAN-2004-0082 to this issue.
+
+Samba administrators not wishing to upgrade to the current
+version should download the 3.0.2 release, build the pdbedit
+tool, and run
+ root# pdbedit-3.0.2 --force-initialized-passwords
+
+This will disable all accounts not possessing a valid password
+(e.g. the password field has been set a string of X's).
-Changes in alpha23:
+Samba servers running 3.0.2 are not vulnerable to this bug
+regardless of whether or not pdbedit has been used to sanitize
+the passdb backend.
+
+Some of the more visible bugs in 3.0.1 addressed in the 3.0.2
+release include:
+
+ o Joining a Samba domain from Pre-SP2 Windows 2000 clients.
+ o Logging onto a Samba domain from Windows XP clients.
+ o Problems with the %U and %u smb.conf variables in relation to
+ Windows 9x/ME clients.
+ o Kerberos failures due to an invalid in memory keytab detection
+ test.
+ o Updates to the ntlm_auth tool.
+ o Fixes for various SMB signing errors.
+ o Better separation of WINS and DNS queries for domain controllers.
+ o Issues with nss_winbind FreeBSD and Solaris.
+ o Several crash bugs in smbd and winbindd.
+ o Output formatting fixes for smbclient for better compatibility
+ with scripts based on the 2.2 version.
+
+
+Changes since 3.0.1
-------------------
- LDAP Group Mapping
- ------------------
+smb.conf changes
+----------------
- pdbedit -i -e sets all SAM_ACCOUNT elements to CHANGED to
- satisfy the new pdb_ldap.c handling. pdbedit -g transfers group
- mappings. I made this separate from the user database, as current
- installations have to live with a split backend. So, if you are
- running 3_0 alphas with LDAP as a backend and upgrade to 3.0alpha23,
- you must call
+ Parameter Name Action
+ -------------- ------
+ ldap replication sleep New
+ read size removed (unused)
+ source environment removed (unused)
- root# pdbedit -i tdbsam -e ldapsam -g
- to transfer your group mapping database to LDAP.
+commits
+-------
- All groups must be represented as posixGroup objects in
- the directory and you must adapt your LDAP schema to support the
- sambaGroupMapping before running this command. Refer to
- examples/LDAP/samba.schema for details on the objectclass.
+Please refer to the CVS log for the SAMBA_3_0 branch for complete
+details. The list of changes per contributor are as follows:

- ChangeLog
- ---------
-
- See cvs log for SAMBA_3_0 for complete details. There are many
- smaller numerous changes that would clutter the release notes.
-
-0) Include security fix from Samba 2.2.8
-1) Fix interop bug in tconX on port 445 with Windows 2000
-2) Interpret missing SMB_ACL_USER_OBJ, SMB_ACL_GROUP_OBJ, or
- SMB_ACL_OTHER as "preserve current value" instead of attempting
- to build one ourself.
-3) Rearrange set_nt_acl() such that chown is only done before
- setting ACLs if there is either no change of owning user, or
- change of owning user is towards the current user. Otherwise
- chown is done after setting ACLs.
-4) Continuing work on NTLMSSP-based SMB signing
-5) When opening an existing TDB, don't require the hash_size
- specified to the open call to be the same as that of the
- existing tdb. The specified hash_size is only used if the
- tdb needs to be (re)created.
-6) Add support for "WinXP" and "Win2K3" client architectures.
-7) Fixed the unmarshalling of the queryaliasmem SAMR call
-8) Windows 2000 can take much longer than the specified time to
- respond to a lock - so to make the torture tests valid I give
- it a grace time of 10 seconds instead of 2
-9) Continued work on string handling paranoia
-10) Merge new statcache.c from HEAD
-11) Add new 'net ads dn' option
-12) Sync up SessionSetup code to HEAD, including Luke Howard's
- session key and auth verifier patches
-13) Work on cleaning up winbindd's mutex locking
-14) Add support for LDAP based Windows group mapping
-15) Improve LDAP update routines
-16) Fix memory leaks found by Valgrind
-17) Add a 'privileged' mode to Winbindd
-18) Work around platforms that have broken getgrnam() implementations
-19) Merge real time signal fixes for kernel oplock code from HEAD
-20) Fix CIDR hosts allow/deny notation
-21) Fixup tcon&X server responses and error codes
-22) Set domain for users in passdb created by "net rpc vampire"
-23) More scalable printing updates

+ winbindd_getusersids() that provides direct SID->SIDs listing of
+ a users supplementary groups. This is enough to allow non-Samba
+ applications to do ACL checking.
+o Make sure we don't append the 'ldap suffix' when writing out the
+ 'ldap XXX suffix' values in SWAT (bug 328).

+ jobid back. This allow users to delete jobs with cups printing
+ backend (partial work on bug 770).
+o Fix build of winbindd with static pdb modules.

+ =======================================
+ WHATS NEW IN Samba 3.0.0
+ September 24, 2003
+ =======================================
+
+
+Major new features:
-------------------
- Added Parameters
+1) Active Directory support. Samba 3.0 is now able to
+ join a ADS realm as a member server and authenticate
+ users using LDAP/Kerberos.
- * client NTLMv2 auth
+2) Unicode support. Samba will now negotiate UNICODE on the wire
+ and internally there is now a much better infrastructure for
+ multi-byte and UNICODE character sets.
+
+3) New authentication system. The internal authentication system
+ has been almost completely rewritten. Most of the changes are
+ internal, but the new auth system is also very configurable.
+
+4) New default filename mangling system.
+
+5) A new "net" command has been added. It is somewhat similar to
+ the "net" command in windows. Eventually we plan to replace
+ numerous other utilities (such as smbpasswd) with subcommands
+ in "net".
+
+6) Samba now negotiates NT-style status32 codes on the wire. This
+ improves error handling a lot.
+
+7) Better Windows 2000/XP/2003 printing support including publishing
+ printer attributes in active directory.
+
+8) New loadable module support for passdb backends and character
+ sets.
+
+9) New default dual-daemon winbindd support for better performance.
+
+10) Support for migrating from a Windows NT 4.0 domain to a Samba
+ domain and maintaining user, group and domain SIDs.
+
+11) Support for establishing trust relationships with Windows NT 4.0
+ domain controllers.
+
+12) Initial support for a distributed Winbind architecture using
+ an LDAP directory for storing SID to uid/gid mappings.
+
+13) Major updates to the Samba documentation tree.
+
+14) Full support for client and server SMB signing to ensure
+ compatibility with default Windows 2003 security settings.
+
+15) Improvement of ACL mapping features based on code donated by
+ Andreas Grünbacher.
+
+
+Plus lots of other improvements!

+######################################################################
+Upgrading from a previous Samba 3.0 beta
+########################################
+
+Beginning with Samba 3.0.0beta3, the RID allocation functions
+have been moved into winbindd. Previously these were handled
+by each passdb backend. This means that winbindd must be running
+to automatically allocate RIDs for users and/or groups. Otherwise,
+smbd will use the 2.2 algorithm for generating new RIDs.
+
+If you are using 'passdb backend = tdbsam' with a previous Samba
+3.0 beta release (or possibly alpha), it may be necessary to
+move the RID_COUNTER entry from /usr/local/samba/private/passdb.tdb
+to winbindd_idmap.tdb. To do this:
+
+1) Ensure that winbindd_idmap.tdb exists (launch winbindd at least
+ once)
+2) build tdbtool by executing 'make tdbtool' in the source/tdb/
+ directory
+3) run: (note that 'tdb>' is the tool's prompt for input)
+
+ root# ./tdbtool /usr/local/samba/private/passdb.tdb
+ tdb> show RID_COUNTER
+ key 12 bytes
+ RID_COUNTER
+ data 4 bytes
+ [000] 0A 52 00 00 .R.
+
+ tdb> move RID_COUNTER /usr/local/samba/var/locks/winbindd_idmap.tdb
+ ....
+ record moved
+
+If you are using 'passdb backend = ldapsam', it will be necessary to
+store idmap entries in the LDAP directory as well (i.e. idmap backend
+= ldap). Refer to the 'net idmap' command for more information on
+migrating SID<->UNIX id mappings from one backend to another.
+
+If the RID_COUNTER record does not exist, then these instructions are
+unneccessary and the new RID_COUNTER record will be correctly generated
+if needed.

+from 3.0 to 2.2 is an unsupported path.
+
+Name Description Backup?
+---- ----------- -------
+account_policy User policy settings yes
+gencache Generic caching db no
+group_mapping Mapping table from Windows yes
+ groups/SID to unix groups
+winbindd_idmap ID map table from SIDS to UNIX yes
+ uids/gids.
+namecache Name resolution cache entries no
+netsamlogon_cache Cache of NET_USER_INFO_3 structure no
+ returned as part of a successful
+ net_sam_logon request
+printing/*.tdb Cached output from 'lpq no
+ command' created on a per print
+ service basis
+registry Read-only samba registry skeleton no
+ that provides support for exporting
+ various db tables via the winreg RPCs
+
+
+Changes in Behavior
+-------------------
+
+The following issues are known changes in behavior between Samba 2.2 and
+Samba 3.0 that may affect certain installations of Samba.
+
+ 1) When operating as a member of a Windows domain, Samba 2.2 would
+ map any users authenticated by the remote DC to the 'guest account'
+ if a uid could not be obtained via the getpwnam() call. Samba 3.0
+ rejects the connection as NT_STATUS_LOGON_FAILURE. There is no
+ current work around to re-establish the 2.2 behavior.
+
+ 2) When adding machines to a Samba 2.2 controlled domain, the
+ 'add user script' was used to create the UNIX identity of the
+ machine trust account. Samba 3.0 introduces a new 'add machine
+ script' that must be specified for this purpose. Samba 3.0 will
+ not fall back to using the 'add user script' in the absence of
+ an 'add machine script'
+
+
+######################################################################
+Passdb Backends and Authentication
+##################################
+
+There have been a few new changes that Samba administrators should be
+aware of when moving to Samba 3.0.
+
+ 1) encrypted passwords have been enabled by default in order to
+ inter-operate better with out-of-the-box Windows client
+ installations. This does mean that either (a) a samba account
+ must be created for each user, or (b) 'encrypt passwords = no'
+ must be explicitly defined in smb.conf.
+
+ 2) Inclusion of new 'security = ads' option for integration
+ with an Active Directory domain using the native Windows
+ Kerberos 5 and LDAP protocols.
+
+ MIT kerberos 1.3.1 supports the ARCFOUR-HMAC-MD5 encryption
+ type which is neccessary for servers on which the
+ administrator password has not been changed, or kerberos-enabled
+ SMB connections to servers that require Kerberos SMB signing.
+ Besides this one difference, either MIT or Heimdal Kerberos
+ distributions are usable by Samba 3.0.
+
+
+Samba 3.0 also includes the possibility of setting up chains
+of authentication methods (auth methods) and account storage
+backends (passdb backend). Please refer to the smb.conf(5)
+man page for details. While both parameters assume sane default
+values, it is likely that you will need to understand what the
+values actually mean in order to ensure Samba operates correctly.
+
+The recommended passdb backends at this time are
+
+ * smbpasswd - 2.2 compatible flat file format
+ * tdbsam - attribute rich database intended as an smbpasswd
+ replacement for stand alone servers
+ * ldapsam - attribute rich account storage and retrieval
+ backend utilizing an LDAP directory.
+ * ldapsam_compat - a 2.2 backward compatible LDAP account
+ backend
+
+Certain functions of the smbpasswd(8) tool have been split between the
+new smbpasswd(8) utility, the net(8) tool, and the new pdbedit(8)
+utility. See the respective man pages for details.
+
+
+######################################################################
+LDAP
+####
+
+This section outlines the new features affecting Samba / LDAP
+integration.
+
+New Schema
+----------
+
+A new object class (sambaSamAccount) has been introduced to replace
+the old sambaAccount. This change aids us in the renaming of
+attributes to prevent clashes with attributes from other vendors.
+There is a conversion script (examples/LDAP/convertSambaAccount) to
+modify and LDIF file to the new schema.
+
+Example:
+
+ $ ldapsearch .... -b "ou=people,dc=..." > sambaAcct.ldif
+ $ convertSambaAccount --sid=<Domain SID> \
+ --input=sambaAcct.ldif --output=sambaSamAcct.ldif \
+ --changetype=[modify|add]
+
+The <DOM SID> can be obtained by running 'net getlocalsid
+<DOMAINNAME>' on the Samba PDC as root. The changetype determines
+the format of the generated LDIF output--either create new entries
+or modify existing entries.
+
+The old sambaAccount schema may still be used by specifying the
+"ldapsam_compat" passdb backend. However, the sambaAccount and
+associated attributes have been moved to the historical section of
+the schema file and must be uncommented before use if needed.
+The 2.2 object class declaration for a sambaAccount has not changed
+in the 3.0 samba.schema file.
+
+Other new object classes and their uses include:
+
+ * sambaDomain - domain information used to allocate rids
+ for users and groups as necessary. The attributes are added
+ in 'ldap suffix' directory entry automatically if
+ an idmap uid/gid range has been set and the 'ldapsam'
+ passdb backend has been selected.
+
+ * sambaGroupMapping - an object representing the
+ relationship between a posixGroup and a Windows
+ group/SID. These entries are stored in the 'ldap
+ group suffix' and managed by the 'net groupmap' command.
+
+ * sambaUnixIdPool - created in the 'ldap idmap suffix' entry
+ automatically and contains the next available 'idmap uid' and
+ 'idmap gid'
+
+ * sambaIdmapEntry - object storing a mapping between a
+ SID and a UNIX uid/gid. These objects are created by the
+ idmap_ldap module as needed.
+
+ * sambaSidEntry - object representing a SID alone, as a Structural
+ class on which to build the sambaIdmapEntry.
+
+
+New Suffix for Searching
+------------------------
+
+The following new smb.conf parameters have been added to aid in directing
+certain LDAP queries when 'passdb backend = ldapsam://...' has been
+specified.
-1) remove the global_myname string and replace with wrapper function
- global_myname()
-2) create vfs/ and pdb/ subdirectories for library installs
-3) Fixup of ordered cleanup of get_dc_list()
-4) Added more autoconf tests for Stratus VOS
-5) Fixed nasty bug where file writes with start offsets in the
- range 0x80000000 -> 0xFFFFFFFF would fail as they were being cast
- from IVAL (uint32) to SMB_OFF_T (off_t or off64_t, both *signed*
- types). The sign extension would cause the offset to be treated
- as negative.
-6) Add support to automatically retrieve the dns host name and domain
- name of an AD server
-7) Add support for PRINTER_INFO_7 and publishing printer attributes
- in active directory
-8) Fix for 64 bit issues with oplocks and allocation size
-9) Remove assert(count ==1) for multi-homed PDCs when resolving
- DOMAIN<0x1b>
-10) Ensure that change_trust_account_password() always talks to
- the PDC
-11) Add some docs on CUPS printing
-12) Fix rpcclient querygroup command
-13) The _abs time functions should not be converting from/to GMT
-14) Fix broken incremental tar in smbclient
-15) Adding supporting code for better testing using Valgrind
-16) Fix for old DOS client when veto files is set to /.*/
-17) Add win32 utility to query driver capabilities to publish
- (examples/printing/prtpub.c)
-18) Fix memory leak when constructing an driver_level_6 structure and
- no dependent files
-19) Add some friendly versions of NT_STATUS codes
-20) Protect nmbd against malformed reply packets
-21) Removal of unpopular winbind client environment variable
-22) Add msdfs proxy functionality; a CIFS share can directly be a
- stand-in for another share, and when clients connect to the first
- share, they will be redirected to the proxied share
-23) Make Samba compile cleanly with -Wwrite-strings
-24) Add new timegm() that actually works on solaris
-25) Add support for running smbd, nmbd, & winbindd under the daemontools
- package
-26) Move user password changes into the NTSTATUS era, and add support
- for the 'min password age' and 'min passwd len' concepts
-27) Add new gencache based namecache code
-28) Add profiles utility support to Samba 3.0.x
-29) Fix open problem with changing attributes on an existing file
-30) Efficiency fixes for internal messaging system
-31) Make sure to update print queue cache during timeout_processing()
- to send notify events
-32) Make -i flag work like it did in 2.2
-33) Merge some rpcclient and net functionality from HEAD
-34) Add support for compiling with Heimdal kerberos libraries
-35) Connect to the actual netbios name in smb.conf and not LOCALHOST
-36) Add support for CUPS-PRINTER_CLASS
-37) Add ntlm_auth tool and update NTLMSSP support
-38) require Autoconf 2.53 and remove configure from CVS
-39) Check for too many processes *before* the fork
-40) Fix delete on close semantics to match W2K.
-41) merge desired_access for open_printer_ex from HEAD, allowing
- cupsaddsmb to work again!
-42) Add support for dynamic RPC modules
-43) wrap all cm_get_XX calls and their subsequent requests in a retry loop
- in case we've temporarily lost connection to the DC. Makes winbindd
- more reliable
-44) Optimize user_ok() and user_in_group() when verifying group membership
-45) Add NTLMv2 client code (that works) and some SMB signing fixes
-46) Add caching of PRINTER_INFO_2 structures to open printer handles
-47) Add 1/3 second delay in OpenPrinter() reply to trigger a LAN/WAN
- optimization in Windows 2000 clients
-48) Add "WinXP" to the possible values of the %a variable
-49) Fix to allow blocking lock notification to be done rapidly (no wait for
- smb -> smb lock release). Adds new PENDING_LOCK type to lockdb (does
- not interfere with existing locks)
-50) Limit the unix domain sockets used by winbindd (also solves FD_SETSIZE
- problem in winbindd to boot !). Adds a "last_access" field to winbindd
- connections, and will close the oldest idle connection once the number
- of open connections goes over WINBINDD_MAX_SIMULTANEOUS_CLIENTS (defined
- in local.h as 200 currently)
-51) Limit the number of print jobs returned in EnumJobs()
+ * ldap suffix - used to search for user and computer accounts
+ * ldap user suffix - used to store user accounts
+ * ldap machine suffix - used to store machine trust accounts
+ * ldap group suffix - location of posixGroup/sambaGroupMapping entries
+ * ldap idmap suffix - location of sambaIdmapEntry objects
+
+If an 'ldap suffix' is defined, it will be appended to all of the
+remaining sub-suffix parameters. In this case, the order of the suffix
+listings in smb.conf is important. Always place the 'ldap suffix' first
+in the list.
+
+Due to a limitation in Samba's smb.conf parsing, you should not surround
+the DN's with quotation marks.
+
+
+IdMap LDAP support
+------------------
+
+Samba 3.0 supports an ldap backend for the idmap subsystem. The
+following options would inform Samba that the idmap table should be
+stored on the directory server onterose in the "ou=idmap,dc=plainjoe,
+dc=org" partition.
+
+ [global]
+ ...
+ idmap backend = ldap:ldap://onterose/
+ ldap idmap suffix = ou=idmap,dc=plainjoe,dc=org
+ idmap uid = 40000-50000
+ idmap gid = 40000-50000
+
+This configuration allows winbind installations on multiple servers to
+share a uid/gid number space, thus avoiding the interoperability problems
+with NFS that were present in Samba 2.2.
+
+
+
+######################################################################
+Trust Relationships and a Samba Domain
+######################################
+
+Samba 3.0.0beta2 is able to utilize winbindd as the means of
+allocating uids and gids to trusted users and groups. More
+information regarding Samba's support for establishing trust
+relationships can be found in the Samba-HOWTO-Collection included
+in the docs/ directory of this release.
+
+First create your Samba PDC and ensure that everything is
+working correctly before moving on the trusts.
+
+To establish Samba as the trusting domain (named SAMBA) from a Windows NT
+4.0 domain named WINDOWS:
+
+ 1) create the trust account for SAMBA in "User Manager for Domains"
+ 2) connect the trust from the Samba domain using
+ 'net rpc trustdom establish GLASS'
+
+To create a trustlationship with SAMBA as the trusted domain:
+
+ 1) create the initial trust account for GLASS using
+ 'smbpasswd -a -i GLASS'. You may need to create a UNIX
+ account for GLASS$ prior to this step (depending on your
+ local configuration).
+ 2) connect the trust from a WINDOWS DC using "User Manager
+ for Domains"
+
+Now join winbindd on the Samba PDC to the SAMBA domain using
+the normal steps for adding a Samba server to an NT4 domain:
+(note that smbd & nmbd must be running at this point)
+
+ root# net rpc join -U root
+ Password: <enter root password from smbpasswd file here>
+
+Start winbindd and test the join with 'wbinfo -t'.
+
+Now test the trust relationship by connecting to the SAMBA DC
+(e.g. POGO) as a user from the WINDOWS domain:
+
+ $ smbclient //pogo/netlogon -U Administrator -W WINDOWS
+ Password:
+
+Now connect to the WINDOWS DC (e.g. CRYSTAL) as a Samba user:
+
+ $ smbclient //crystal/netlogon -U root -W WINDOWS
+ Password:
+
+######################################################################
+Changes in Winbind
+##################
+
+Beginning with Samba3.0.0beta3, winbindd has been given new account
+manage functionality equivalent to the 'add user script' family of
+smb.conf parameters. The idmap design has also been changed to
+centralize control of foreign SID lookups and matching to UNIX
+uids and gids.
+
+
+Brief Description of Changes
+----------------------------
+
+1) The sid_to_uid() family of functions (smbd/uid.c) have been
+ reverted to the 2.2.x design. This means that when resolving a
+ SID to a UID or similar mapping:
+
+ a) First consult winbindd
+ b) perform a local lookup only if winbindd fails to
+ return a successful answer
+
+ There are some variations to this, but these two rules generally
+ apply.
+
+2) All idmap lookups have been moved into winbindd. This means that
+ a server must run winbindd (and support NSS) in order to achieve
+ any mappings of SID to dynamically allocated UNIX ids. This was
+ a conscious design choice.
+
+3) New functions have been added to winbindd to emulate the 'add user
+ script' family of smbd functions without requiring that external
+ scripts be defined. This functionality is controlled by the 'winbind
+ enable local accounts' smb.conf parameter (enabled by default).
+
+ However, this account management functionality is only supported
+ in a local tdb (winbindd_idmap.tdb). If these new UNIX accounts
+ must be shared among multiple Samba servers (such as a PDC and BDCs),
+ it will be necessary to define your own 'add user script', et. al.
+ programs that place the accounts/groups in some form of directory
+ such as NIS or LDAP. This requirement was deemed beyond the scope
+ of winbind's account management functions. Solutions for
+ distributing UNIX system information have been deployed and tested
+ for many years. We saw no need to reinvent the wheel.
+
+4) A member of a Samba controlled domain running winbindd is now able
+ to map domain users directly onto existing UNIX accounts while still
+ automatically creating accounts for trusted users and groups. This
+ behavior is controlled by the 'winbind trusted domains only' smb.conf
+ parameter (disabled by default to provide 2.2.x winbind behavior).
+
+5) Group mapping support is wrapped in the local_XX_to_XX() functions
+ in smbd/uid.c. The reason that group mappings are not included
+ in winbindd is because the purpose of Samba's group map is to
+ match any Windows SID with an existing UNIX group. These UNIX
+ groups can be created by winbindd (see next section), but the
+ SID<->gid mapping is retreived by smbd, not winbindd.
+
+
+Examples
+--------
+
+* security = server running winbindd to allocate accounts on demand
+
+* Samba PDC running winbindd to handle the automatic creation of UNIX
+ identities for machine trust accounts
+
+* Automtically creating UNIX user and groups when migrating a Windows NT
+ 4.0 PDC to a Samba PDC. Winbindd must be running when executing
+ 'net rpc vampire' for this to work.
