381 o Ensure we mangle names ending in '.' in hash2 mangling method.
382 o Correct parsing issues with munged dial string.
383 o Fix bugs in quota support for XFS.
384 o Add a cleaner method for applications that need to provide
385 name->SID mappings to do this via NSS rather than having to
386 know the winbindd pipe protocol.
387 o Adds a variant of the winbindd_getgroups() call called
388 winbindd_getusersids() that provides direct SID->SIDs listing of
389 a users supplementary groups. This is enough to allow non-Samba
390 applications to do ACL checking.
391 o Make sure we don't append the 'ldap suffix' when writing out the
392 'ldap XXX suffix' values in SWAT (bug 328).
393 o Fix renames across file systems.

413 to "smbprn.00000033 Test Page" so that we can get the smb
414 jobid back. This allow users to delete jobs with cups printing
415 backend (partial work on bug 770).
416 o Fix build of winbindd with static pdb modules.

479 ######################################################################
481 =======================================
482 The original 3.0.0 release notes follow
483 =======================================
489 1) Active Directory support. Samba 3.0 is now able to
490 join a ADS realm as a member server and authenticate
491 users using LDAP/Kerberos.
493 2) Unicode support. Samba will now negotiate UNICODE on the wire
494 and internally there is now a much better infrastructure for
495 multi-byte and UNICODE character sets.
497 3) New authentication system. The internal authentication system
498 has been almost completely rewritten. Most of the changes are
499 internal, but the new auth system is also very configurable.
501 4) New default filename mangling system.
503 5) A new "net" command has been added. It is somewhat similar to
504 the "net" command in windows. Eventually we plan to replace
505 numerous other utilities (such as smbpasswd) with subcommands
508 6) Samba now negotiates NT-style status32 codes on the wire. This
509 improves error handling a lot.
511 7) Better Windows 2000/XP/2003 printing support including publishing
512 printer attributes in active directory.
514 8) New loadable module support for passdb backends and character
517 9) New default dual-daemon winbindd support for better performance.
519 10) Support for migrating from a Windows NT 4.0 domain to a Samba
520 domain and maintaining user, group and domain SIDs.
522 11) Support for establishing trust relationships with Windows NT 4.0
525 12) Initial support for a distributed Winbind architecture using
526 an LDAP directory for storing SID to uid/gid mappings.
528 13) Major updates to the Samba documentation tree.
530 14) Full support for client and server SMB signing to ensure
531 compatibility with default Windows 2003 security settings.
533 15) Improvement of ACL mapping features based on code donated by
537 Plus lots of other improvements!
540 Additional Documentation
541 ------------------------
543 Please refer to Samba documentation tree (included in the docs/
544 subdirectory) for extensive explanations of installing, configuring
545 and maintaining Samba 3.0 servers and clients. It is advised to
546 begin with the Samba-HOWTO-Collection for overviews and specific
547 tasks (the current book is up to approximately 400 pages) and to
548 refer to the various man pages for information on individual options.
550 We are very glad to be able to include the second edition of
551 "Using Samba" by Jay Ts, Robert Eckstein, and David Collier-Brown
552 (O'Reilly & Associates) in this release. The book is available
553 on-line at http://samba.org/samba/docs/ and is included with
554 the Samba Web Administration Tool (SWAT). Thanks to the authors and
555 publisher for making "Using Samba" under the GNU Free Documentation
559 ######################################################################
560 Upgrading from a previous Samba 3.0 beta
561 ########################################
563 Beginning with Samba 3.0.0beta3, the RID allocation functions
564 have been moved into winbindd. Previously these were handled
565 by each passdb backend. This means that winbindd must be running
566 to automatically allocate RIDs for users and/or groups. Otherwise,
567 smbd will use the 2.2 algorithm for generating new RIDs.
569 If you are using 'passdb backend = tdbsam' with a previous Samba
570 3.0 beta release (or possibly alpha), it may be necessary to
571 move the RID_COUNTER entry from /usr/local/samba/private/passdb.tdb
572 to winbindd_idmap.tdb. To do this:
574 1) Ensure that winbindd_idmap.tdb exists (launch winbindd at least
576 2) build tdbtool by executing 'make tdbtool' in the source/tdb/
578 3) run: (note that 'tdb>' is the tool's prompt for input)
580 root# ./tdbtool /usr/local/samba/private/passdb.tdb
581 tdb> show RID_COUNTER
585 [000] 0A 52 00 00 .R.
587 tdb> move RID_COUNTER /usr/local/samba/var/locks/winbindd_idmap.tdb
591 If you are using 'passdb backend = ldapsam', it will be necessary to
592 store idmap entries in the LDAP directory as well (i.e. idmap backend
593 = ldap). Refer to the 'net idmap' command for more information on
594 migrating SID<->UNIX id mappings from one backend to another.
596 If the RID_COUNTER record does not exist, then these instructions are
597 unneccessary and the new RID_COUNTER record will be correctly generated

603 Upgrading from Samba 2.2
604 ########################
606 This section is provided to help administrators understand the details
607 involved with upgrading a Samba 2.2 server to Samba 3.0.
613 Many of the options to the GNU autoconf script have been modified
614 in the 3.0 release. The most noticeable are:
616 * removal of --with-tdbsam (is now included by default; see section
617 on passdb backends and authentication for more details)
619 * --with-ldapsam is now on used to provided backward compatible
620 parameters for LDAP enabled Samba 2.2 servers. Refer to the passdb
621 backend and authentication section for more details
623 * inclusion of non-standard passdb modules may be enabled using
624 --with-expsam. This includes an XML backend and a mysql backend.
626 * removal of --with-msdfs (is now enabled by default)
628 * removal of --with-ssl (no longer supported)
630 * --with-utmp now defaults to 'yes' on supported systems
632 * --with-sendfile-support is now enabled by default on supported
639 This section contains a brief listing of changes to smb.conf options

773 This section contains brief descriptions of any new databases
774 introduced in Samba 3.0. Please remember to backup your existing
775 ${lock directory}/*tdb before upgrading to Samba 3.0. Samba will
776 upgrade databases as they are opened (if necessary), but downgrading
777 from 3.0 to 2.2 is an unsupported path.
779 Name Description Backup?
780 ---- ----------- -------
781 account_policy User policy settings yes
782 gencache Generic caching db no
783 group_mapping Mapping table from Windows yes
784 groups/SID to unix groups
785 winbindd_idmap ID map table from SIDS to UNIX yes
787 namecache Name resolution cache entries no
788 netsamlogon_cache Cache of NET_USER_INFO_3 structure no
789 returned as part of a successful
790 net_sam_logon request
791 printing/*.tdb Cached output from 'lpq no
792 command' created on a per print
794 registry Read-only samba registry skeleton no
795 that provides support for exporting
796 various db tables via the winreg RPCs
802 The following issues are known changes in behavior between Samba 2.2 and
803 Samba 3.0 that may affect certain installations of Samba.
805 1) When operating as a member of a Windows domain, Samba 2.2 would
806 map any users authenticated by the remote DC to the 'guest account'
807 if a uid could not be obtained via the getpwnam() call. Samba 3.0
808 rejects the connection as NT_STATUS_LOGON_FAILURE. There is no
809 current work around to re-establish the 2.2 behavior.
811 2) When adding machines to a Samba 2.2 controlled domain, the
812 'add user script' was used to create the UNIX identity of the
813 machine trust account. Samba 3.0 introduces a new 'add machine
814 script' that must be specified for this purpose. Samba 3.0 will
815 not fall back to using the 'add user script' in the absence of
816 an 'add machine script'
819 ######################################################################
820 Passdb Backends and Authentication
821 ##################################
823 There have been a few new changes that Samba administrators should be
824 aware of when moving to Samba 3.0.
826 1) encrypted passwords have been enabled by default in order to
827 inter-operate better with out-of-the-box Windows client
828 installations. This does mean that either (a) a samba account
829 must be created for each user, or (b) 'encrypt passwords = no'
830 must be explicitly defined in smb.conf.
832 2) Inclusion of new 'security = ads' option for integration
833 with an Active Directory domain using the native Windows
834 Kerberos 5 and LDAP protocols.
836 MIT kerberos 1.3.1 supports the ARCFOUR-HMAC-MD5 encryption
837 type which is neccessary for servers on which the
838 administrator password has not been changed, or kerberos-enabled
839 SMB connections to servers that require Kerberos SMB signing.
840 Besides this one difference, either MIT or Heimdal Kerberos
841 distributions are usable by Samba 3.0.
844 Samba 3.0 also includes the possibility of setting up chains
845 of authentication methods (auth methods) and account storage
846 backends (passdb backend). Please refer to the smb.conf(5)
847 man page for details. While both parameters assume sane default
848 values, it is likely that you will need to understand what the
849 values actually mean in order to ensure Samba operates correctly.
851 The recommended passdb backends at this time are
853 * smbpasswd - 2.2 compatible flat file format
854 * tdbsam - attribute rich database intended as an smbpasswd
855 replacement for stand alone servers
856 * ldapsam - attribute rich account storage and retrieval
857 backend utilizing an LDAP directory.
858 * ldapsam_compat - a 2.2 backward compatible LDAP account
861 Certain functions of the smbpasswd(8) tool have been split between the
862 new smbpasswd(8) utility, the net(8) tool, and the new pdbedit(8)
863 utility. See the respective man pages for details.
866 ######################################################################
870 This section outlines the new features affecting Samba / LDAP
876 A new object class (sambaSamAccount) has been introduced to replace
877 the old sambaAccount. This change aids us in the renaming of attributes
878 to prevent clashes with attributes from other vendors. There is a
879 conversion script (examples/LDAP/convertSambaAccount) to modify and LDIF
880 file to the new schema.
884 $ ldapsearch .... -b "ou=people,dc=..." > old.ldif
885 $ convertSambaAccount <DOM SID> old.ldif new.ldif
887 The <DOM SID> can be obtained by running 'net getlocalsid <DOMAINNAME>'
888 on the Samba PDC as root.
890 The old sambaAccount schema may still be used by specifying the
891 "ldapsam_compat" passdb backend. However, the sambaAccount and
892 associated attributes have been moved to the historical section of
893 the schema file and must be uncommented before use if needed.
894 The 2.2 object class declaration for a sambaAccount has not changed
895 in the 3.0 samba.schema file.
897 Other new object classes and their uses include:
899 * sambaDomain - domain information used to allocate rids
900 for users and groups as necessary. The attributes are added
901 in 'ldap suffix' directory entry automatically if
902 an idmap uid/gid range has been set and the 'ldapsam'
903 passdb backend has been selected.
905 * sambaGroupMapping - an object representing the
906 relationship between a posixGroup and a Windows
907 group/SID. These entries are stored in the 'ldap
908 group suffix' and managed by the 'net groupmap' command.
910 * sambaUnixIdPool - created in the 'ldap idmap suffix' entry
911 automatically and contains the next available 'idmap uid' and
914 * sambaIdmapEntry - object storing a mapping between a
915 SID and a UNIX uid/gid. These objects are created by the
916 idmap_ldap module as needed.
918 * sambaSidEntry - object representing a SID alone, as a Structural
919 class on which to build the sambaIdmapEntry.
922 New Suffix for Searching
923 ------------------------
925 The following new smb.conf parameters have been added to aid in directing
926 certain LDAP queries when 'passdb backend = ldapsam://...' has been
929 * ldap suffix - used to search for user and computer accounts
930 * ldap user suffix - used to store user accounts
931 * ldap machine suffix - used to store machine trust accounts
932 * ldap group suffix - location of posixGroup/sambaGroupMapping entries
933 * ldap idmap suffix - location of sambaIdmapEntry objects
935 If an 'ldap suffix' is defined, it will be appended to all of the
936 remaining sub-suffix parameters. In this case, the order of the suffix
937 listings in smb.conf is important. Always place the 'ldap suffix' first
940 Due to a limitation in Samba's smb.conf parsing, you should not surround
941 the DN's with quotation marks.
947 Samba 3.0 supports an ldap backend for the idmap subsystem. The
948 following options would inform Samba that the idmap table should be
949 stored on the directory server onterose in the "ou=idmap,dc=plainjoe,
954 idmap backend = ldap:ldap://onterose/
955 ldap idmap suffix = ou=idmap,dc=plainjoe,dc=org
956 idmap uid = 40000-50000
957 idmap gid = 40000-50000
959 This configuration allows winbind installations on multiple servers to
960 share a uid/gid number space, thus avoiding the interoperability problems
961 with NFS that were present in Samba 2.2.
965 ######################################################################
966 Trust Relationships and a Samba Domain
967 ######################################
969 Samba 3.0.0beta2 is able to utilize winbindd as the means of
970 allocating uids and gids to trusted users and groups. More
971 information regarding Samba's support for establishing trust
972 relationships can be found in the Samba-HOWTO-Collection included
973 in the docs/ directory of this release.
975 First create your Samba PDC and ensure that everything is
976 working correctly before moving on the trusts.
978 To establish Samba as the trusting domain (named SAMBA) from a Windows NT
979 4.0 domain named WINDOWS:
981 1) create the trust account for SAMBA in "User Manager for Domains"
982 2) connect the trust from the Samba domain using
983 'net rpc trustdom establish GLASS'
985 To create a trustlationship with SAMBA as the trusted domain:
987 1) create the initial trust account for GLASS using
988 'smbpasswd -a -i GLASS'. You may need to create a UNIX
989 account for GLASS$ prior to this step (depending on your
990 local configuration).
991 2) connect the trust from a WINDOWS DC using "User Manager
994 Now join winbindd on the Samba PDC to the SAMBA domain using
995 the normal steps for adding a Samba server to an NT4 domain:
996 (note that smbd & nmbd must be running at this point)
998 root# net rpc join -U root
999 Password: <enter root password from smbpasswd file here>
1001 Start winbindd and test the join with 'wbinfo -t'.
1003 Now test the trust relationship by connecting to the SAMBA DC
1004 (e.g. POGO) as a user from the WINDOWS domain:
1006 $ smbclient //pogo/netlogon -U Administrator -W WINDOWS
1009 Now connect to the WINDOWS DC (e.g. CRYSTAL) as a Samba user:
1011 $ smbclient //crystal/netlogon -U root -W WINDOWS
1014 ######################################################################
1018 Beginning with Samba3.0.0beta3, winbindd has been given new account
1019 manage functionality equivalent to the 'add user script' family of
1020 smb.conf parameters. The idmap design has also been changed to
1021 centralize control of foreign SID lookups and matching to UNIX
1025 Brief Description of Changes
1026 ----------------------------
1028 1) The sid_to_uid() family of functions (smbd/uid.c) have been
1029 reverted to the 2.2.x design. This means that when resolving a
1030 SID to a UID or similar mapping:
1032 a) First consult winbindd
1033 b) perform a local lookup only if winbindd fails to
1034 return a successful answer
1036 There are some variations to this, but these two rules generally
1039 2) All idmap lookups have been moved into winbindd. This means that
1040 a server must run winbindd (and support NSS) in order to achieve
1041 any mappings of SID to dynamically allocated UNIX ids. This was
1042 a conscious design choice.
1044 3) New functions have been added to winbindd to emulate the 'add user
1045 script' family of smbd functions without requiring that external
1046 scripts be defined. This functionality is controlled by the 'winbind
1047 enable local accounts' smb.conf parameter (enabled by default).
1049 However, this account management functionality is only supported
1050 in a local tdb (winbindd_idmap.tdb). If these new UNIX accounts
1051 must be shared among multiple Samba servers (such as a PDC and BDCs),
1052 it will be necessary to define your own 'add user script', et. al.
1053 programs that place the accounts/groups in some form of directory
1054 such as NIS or LDAP. This requirement was deemed beyond the scope
1055 of winbind's account management functions. Solutions for
1056 distributing UNIX system information have been deployed and tested
1057 for many years. We saw no need to reinvent the wheel.
1059 4) A member of a Samba controlled domain running winbindd is now able
1060 to map domain users directly onto existing UNIX accounts while still
1061 automatically creating accounts for trusted users and groups. This
1062 behavior is controlled by the 'winbind trusted domains only' smb.conf
1063 parameter (disabled by default to provide 2.2.x winbind behavior).
1065 5) Group mapping support is wrapped in the local_XX_to_XX() functions
1066 in smbd/uid.c. The reason that group mappings are not included
1067 in winbindd is because the purpose of Samba's group map is to
1068 match any Windows SID with an existing UNIX group. These UNIX
1069 groups can be created by winbindd (see next section), but the
1070 SID<->gid mapping is retreived by smbd, not winbindd.
1076 * security = server running winbindd to allocate accounts on demand
1078 * Samba PDC running winbindd to handle the automatic creation of UNIX
1079 identities for machine trust accounts
1081 * Automtically creating UNIX user and groups when migrating a Windows NT
1082 4.0 PDC to a Samba PDC. Winbindd must be running when executing
1083 'net rpc vampire' for this to work.
