353 o Correct parsing issues with munged dial string.
354 o Fix bugs in quota support for XFS.
355 o Add a cleaner method for applications that need to provide
356 name->SID mappings to do this via NSS rather than having to

358 o Adds a variant of the winbindd_getgroups() call called
359 winbindd_getusersids() that provides direct SID->SIDs listing of
360 a users supplementary groups. This is enough to allow non-Samba
361 applications to do ACL checking.
362 o Make sure we don't append the 'ldap suffix' when writing out the
363 'ldap XXX suffix' values in SWAT (bug 328).
364 o Fix renames across file systems.

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

450 ######################################################################
452 =======================================
453 The original 3.0.0 release notes follow
454 =======================================
460 1) Active Directory support. Samba 3.0 is now able to
461 join a ADS realm as a member server and authenticate
462 users using LDAP/Kerberos.
464 2) Unicode support. Samba will now negotiate UNICODE on the wire
465 and internally there is now a much better infrastructure for
466 multi-byte and UNICODE character sets.
468 3) New authentication system. The internal authentication system
469 has been almost completely rewritten. Most of the changes are
470 internal, but the new auth system is also very configurable.
472 4) New default filename mangling system.
474 5) A new "net" command has been added. It is somewhat similar to
475 the "net" command in windows. Eventually we plan to replace
476 numerous other utilities (such as smbpasswd) with subcommands
479 6) Samba now negotiates NT-style status32 codes on the wire. This
480 improves error handling a lot.
482 7) Better Windows 2000/XP/2003 printing support including publishing
483 printer attributes in active directory.
485 8) New loadable module support for passdb backends and character
488 9) New default dual-daemon winbindd support for better performance.
490 10) Support for migrating from a Windows NT 4.0 domain to a Samba
491 domain and maintaining user, group and domain SIDs.
493 11) Support for establishing trust relationships with Windows NT 4.0
496 12) Initial support for a distributed Winbind architecture using
497 an LDAP directory for storing SID to uid/gid mappings.
499 13) Major updates to the Samba documentation tree.
501 14) Full support for client and server SMB signing to ensure
502 compatibility with default Windows 2003 security settings.
504 15) Improvement of ACL mapping features based on code donated by
508 Plus lots of other improvements!
511 Additional Documentation
512 ------------------------
514 Please refer to Samba documentation tree (included in the docs/
515 subdirectory) for extensive explanations of installing, configuring
516 and maintaining Samba 3.0 servers and clients. It is advised to
517 begin with the Samba-HOWTO-Collection for overviews and specific
518 tasks (the current book is up to approximately 400 pages) and to
519 refer to the various man pages for information on individual options.
521 We are very glad to be able to include the second edition of
522 "Using Samba" by Jay Ts, Robert Eckstein, and David Collier-Brown
523 (O'Reilly & Associates) in this release. The book is available
524 on-line at http://samba.org/samba/docs/ and is included with
525 the Samba Web Administration Tool (SWAT). Thanks to the authors and
526 publisher for making "Using Samba" under the GNU Free Documentation
530 ######################################################################
531 Upgrading from a previous Samba 3.0 beta
532 ########################################
534 Beginning with Samba 3.0.0beta3, the RID allocation functions
535 have been moved into winbindd. Previously these were handled
536 by each passdb backend. This means that winbindd must be running
537 to automatically allocate RIDs for users and/or groups. Otherwise,
538 smbd will use the 2.2 algorithm for generating new RIDs.
540 If you are using 'passdb backend = tdbsam' with a previous Samba
541 3.0 beta release (or possibly alpha), it may be necessary to
542 move the RID_COUNTER entry from /usr/local/samba/private/passdb.tdb
543 to winbindd_idmap.tdb. To do this:
545 1) Ensure that winbindd_idmap.tdb exists (launch winbindd at least
547 2) build tdbtool by executing 'make tdbtool' in the source/tdb/
549 3) run: (note that 'tdb>' is the tool's prompt for input)
551 root# ./tdbtool /usr/local/samba/private/passdb.tdb
552 tdb> show RID_COUNTER
556 [000] 0A 52 00 00 .R.
558 tdb> move RID_COUNTER /usr/local/samba/var/locks/winbindd_idmap.tdb
562 If you are using 'passdb backend = ldapsam', it will be necessary to
563 store idmap entries in the LDAP directory as well (i.e. idmap backend
564 = ldap). Refer to the 'net idmap' command for more information on
565 migrating SID<->UNIX id mappings from one backend to another.
567 If the RID_COUNTER record does not exist, then these instructions are
568 unneccessary and the new RID_COUNTER record will be correctly generated

574 Upgrading from Samba 2.2
575 ########################
577 This section is provided to help administrators understand the details
578 involved with upgrading a Samba 2.2 server to Samba 3.0.
584 Many of the options to the GNU autoconf script have been modified
585 in the 3.0 release. The most noticeable are:
587 * removal of --with-tdbsam (is now included by default; see section
588 on passdb backends and authentication for more details)
590 * --with-ldapsam is now on used to provided backward compatible
591 parameters for LDAP enabled Samba 2.2 servers. Refer to the passdb
592 backend and authentication section for more details
594 * inclusion of non-standard passdb modules may be enabled using
595 --with-expsam. This includes an XML backend and a mysql backend.
597 * removal of --with-msdfs (is now enabled by default)
599 * removal of --with-ssl (no longer supported)
601 * --with-utmp now defaults to 'yes' on supported systems

745 introduced in Samba 3.0. Please remember to backup your existing
746 ${lock directory}/*tdb before upgrading to Samba 3.0. Samba will
747 upgrade databases as they are opened (if necessary), but downgrading
748 from 3.0 to 2.2 is an unsupported path.
750 Name Description Backup?
751 ---- ----------- -------
752 account_policy User policy settings yes
753 gencache Generic caching db no
754 group_mapping Mapping table from Windows yes
755 groups/SID to unix groups
756 winbindd_idmap ID map table from SIDS to UNIX yes
758 namecache Name resolution cache entries no
759 netsamlogon_cache Cache of NET_USER_INFO_3 structure no

761 net_sam_logon request
762 printing/*.tdb Cached output from 'lpq no
763 command' created on a per print
765 registry Read-only samba registry skeleton no
766 that provides support for exporting
767 various db tables via the winreg RPCs
773 The following issues are known changes in behavior between Samba 2.2 and
774 Samba 3.0 that may affect certain installations of Samba.
776 1) When operating as a member of a Windows domain, Samba 2.2 would
777 map any users authenticated by the remote DC to the 'guest account'
778 if a uid could not be obtained via the getpwnam() call. Samba 3.0
779 rejects the connection as NT_STATUS_LOGON_FAILURE. There is no
780 current work around to re-establish the 2.2 behavior.
782 2) When adding machines to a Samba 2.2 controlled domain, the
783 'add user script' was used to create the UNIX identity of the
784 machine trust account. Samba 3.0 introduces a new 'add machine
785 script' that must be specified for this purpose. Samba 3.0 will
786 not fall back to using the 'add user script' in the absence of
787 an 'add machine script'
790 ######################################################################
791 Passdb Backends and Authentication
792 ##################################
794 There have been a few new changes that Samba administrators should be
795 aware of when moving to Samba 3.0.
797 1) encrypted passwords have been enabled by default in order to
798 inter-operate better with out-of-the-box Windows client
799 installations. This does mean that either (a) a samba account
800 must be created for each user, or (b) 'encrypt passwords = no'
801 must be explicitly defined in smb.conf.
803 2) Inclusion of new 'security = ads' option for integration
804 with an Active Directory domain using the native Windows
805 Kerberos 5 and LDAP protocols.
807 MIT kerberos 1.3.1 supports the ARCFOUR-HMAC-MD5 encryption
808 type which is neccessary for servers on which the
809 administrator password has not been changed, or kerberos-enabled
810 SMB connections to servers that require Kerberos SMB signing.
811 Besides this one difference, either MIT or Heimdal Kerberos
812 distributions are usable by Samba 3.0.
815 Samba 3.0 also includes the possibility of setting up chains
816 of authentication methods (auth methods) and account storage
817 backends (passdb backend). Please refer to the smb.conf(5)
818 man page for details. While both parameters assume sane default
819 values, it is likely that you will need to understand what the
820 values actually mean in order to ensure Samba operates correctly.
822 The recommended passdb backends at this time are
824 * smbpasswd - 2.2 compatible flat file format
825 * tdbsam - attribute rich database intended as an smbpasswd
826 replacement for stand alone servers
827 * ldapsam - attribute rich account storage and retrieval
828 backend utilizing an LDAP directory.
829 * ldapsam_compat - a 2.2 backward compatible LDAP account
832 Certain functions of the smbpasswd(8) tool have been split between the
833 new smbpasswd(8) utility, the net(8) tool, and the new pdbedit(8)
834 utility. See the respective man pages for details.
837 ######################################################################
841 This section outlines the new features affecting Samba / LDAP
847 A new object class (sambaSamAccount) has been introduced to replace
848 the old sambaAccount. This change aids us in the renaming of attributes
849 to prevent clashes with attributes from other vendors. There is a
850 conversion script (examples/LDAP/convertSambaAccount) to modify and LDIF
851 file to the new schema.
855 $ ldapsearch .... -b "ou=people,dc=..." > old.ldif
856 $ convertSambaAccount <DOM SID> old.ldif new.ldif
858 The <DOM SID> can be obtained by running 'net getlocalsid <DOMAINNAME>'
859 on the Samba PDC as root.
861 The old sambaAccount schema may still be used by specifying the
862 "ldapsam_compat" passdb backend. However, the sambaAccount and
863 associated attributes have been moved to the historical section of
864 the schema file and must be uncommented before use if needed.
865 The 2.2 object class declaration for a sambaAccount has not changed
866 in the 3.0 samba.schema file.
868 Other new object classes and their uses include:
870 * sambaDomain - domain information used to allocate rids
871 for users and groups as necessary. The attributes are added
872 in 'ldap suffix' directory entry automatically if
873 an idmap uid/gid range has been set and the 'ldapsam'
874 passdb backend has been selected.
876 * sambaGroupMapping - an object representing the
877 relationship between a posixGroup and a Windows
878 group/SID. These entries are stored in the 'ldap
879 group suffix' and managed by the 'net groupmap' command.
881 * sambaUnixIdPool - created in the 'ldap idmap suffix' entry
882 automatically and contains the next available 'idmap uid' and
885 * sambaIdmapEntry - object storing a mapping between a
886 SID and a UNIX uid/gid. These objects are created by the
887 idmap_ldap module as needed.
889 * sambaSidEntry - object representing a SID alone, as a Structural
890 class on which to build the sambaIdmapEntry.
893 New Suffix for Searching
894 ------------------------
896 The following new smb.conf parameters have been added to aid in directing
897 certain LDAP queries when 'passdb backend = ldapsam://...' has been
900 * ldap suffix - used to search for user and computer accounts
901 * ldap user suffix - used to store user accounts
902 * ldap machine suffix - used to store machine trust accounts
903 * ldap group suffix - location of posixGroup/sambaGroupMapping entries
904 * ldap idmap suffix - location of sambaIdmapEntry objects
906 If an 'ldap suffix' is defined, it will be appended to all of the
907 remaining sub-suffix parameters. In this case, the order of the suffix
908 listings in smb.conf is important. Always place the 'ldap suffix' first
911 Due to a limitation in Samba's smb.conf parsing, you should not surround
912 the DN's with quotation marks.
918 Samba 3.0 supports an ldap backend for the idmap subsystem. The
919 following options would inform Samba that the idmap table should be
920 stored on the directory server onterose in the "ou=idmap,dc=plainjoe,
925 idmap backend = ldap:ldap://onterose/
926 ldap idmap suffix = ou=idmap,dc=plainjoe,dc=org
927 idmap uid = 40000-50000
928 idmap gid = 40000-50000
930 This configuration allows winbind installations on multiple servers to
931 share a uid/gid number space, thus avoiding the interoperability problems
932 with NFS that were present in Samba 2.2.
936 ######################################################################
937 Trust Relationships and a Samba Domain
938 ######################################
940 Samba 3.0.0beta2 is able to utilize winbindd as the means of
941 allocating uids and gids to trusted users and groups. More
942 information regarding Samba's support for establishing trust
943 relationships can be found in the Samba-HOWTO-Collection included
944 in the docs/ directory of this release.
946 First create your Samba PDC and ensure that everything is
947 working correctly before moving on the trusts.
949 To establish Samba as the trusting domain (named SAMBA) from a Windows NT
950 4.0 domain named WINDOWS:
952 1) create the trust account for SAMBA in "User Manager for Domains"
953 2) connect the trust from the Samba domain using
954 'net rpc trustdom establish GLASS'
956 To create a trustlationship with SAMBA as the trusted domain:
958 1) create the initial trust account for GLASS using
959 'smbpasswd -a -i GLASS'. You may need to create a UNIX
960 account for GLASS$ prior to this step (depending on your
961 local configuration).
962 2) connect the trust from a WINDOWS DC using "User Manager
965 Now join winbindd on the Samba PDC to the SAMBA domain using
966 the normal steps for adding a Samba server to an NT4 domain:
967 (note that smbd & nmbd must be running at this point)
969 root# net rpc join -U root
970 Password: <enter root password from smbpasswd file here>
972 Start winbindd and test the join with 'wbinfo -t'.
974 Now test the trust relationship by connecting to the SAMBA DC
975 (e.g. POGO) as a user from the WINDOWS domain:
977 $ smbclient //pogo/netlogon -U Administrator -W WINDOWS
980 Now connect to the WINDOWS DC (e.g. CRYSTAL) as a Samba user:
982 $ smbclient //crystal/netlogon -U root -W WINDOWS
985 ######################################################################
989 Beginning with Samba3.0.0beta3, winbindd has been given new account
990 manage functionality equivalent to the 'add user script' family of
991 smb.conf parameters. The idmap design has also been changed to
992 centralize control of foreign SID lookups and matching to UNIX
996 Brief Description of Changes
997 ----------------------------
999 1) The sid_to_uid() family of functions (smbd/uid.c) have been
1000 reverted to the 2.2.x design. This means that when resolving a
1001 SID to a UID or similar mapping:
1003 a) First consult winbindd
1004 b) perform a local lookup only if winbindd fails to
1005 return a successful answer
1007 There are some variations to this, but these two rules generally
1010 2) All idmap lookups have been moved into winbindd. This means that
1011 a server must run winbindd (and support NSS) in order to achieve
1012 any mappings of SID to dynamically allocated UNIX ids. This was
1013 a conscious design choice.
1015 3) New functions have been added to winbindd to emulate the 'add user
1016 script' family of smbd functions without requiring that external
1017 scripts be defined. This functionality is controlled by the 'winbind
1018 enable local accounts' smb.conf parameter (enabled by default).
1020 However, this account management functionality is only supported
1021 in a local tdb (winbindd_idmap.tdb). If these new UNIX accounts
1022 must be shared among multiple Samba servers (such as a PDC and BDCs),
1023 it will be necessary to define your own 'add user script', et. al.
1024 programs that place the accounts/groups in some form of directory
1025 such as NIS or LDAP. This requirement was deemed beyond the scope
1026 of winbind's account management functions. Solutions for
1027 distributing UNIX system information have been deployed and tested
1028 for many years. We saw no need to reinvent the wheel.
1030 4) A member of a Samba controlled domain running winbindd is now able
1031 to map domain users directly onto existing UNIX accounts while still
1032 automatically creating accounts for trusted users and groups. This
1033 behavior is controlled by the 'winbind trusted domains only' smb.conf
1034 parameter (disabled by default to provide 2.2.x winbind behavior).
1036 5) Group mapping support is wrapped in the local_XX_to_XX() functions
1037 in smbd/uid.c. The reason that group mappings are not included
1038 in winbindd is because the purpose of Samba's group map is to
1039 match any Windows SID with an existing UNIX group. These UNIX
1040 groups can be created by winbindd (see next section), but the
1041 SID<->gid mapping is retreived by smbd, not winbindd.
1047 * security = server running winbindd to allocate accounts on demand
1049 * Samba PDC running winbindd to handle the automatic creation of UNIX
1050 identities for machine trust accounts
1052 * Automtically creating UNIX user and groups when migrating a Windows NT
1053 4.0 PDC to a Samba PDC. Winbindd must be running when executing
1054 'net rpc vampire' for this to work.
