438 winbindd_getusersids() that provides direct SID->SIDs listing of
439 a users supplementary groups. This is enough to allow non-Samba
440 applications to do ACL checking.

529 ######################################################################
531 =======================================
532 The original 3.0.0 release notes follow
533 =======================================
539 1) Active Directory support. Samba 3.0 is now able to
540 join a ADS realm as a member server and authenticate
541 users using LDAP/Kerberos.
543 2) Unicode support. Samba will now negotiate UNICODE on the wire
544 and internally there is now a much better infrastructure for
545 multi-byte and UNICODE character sets.
547 3) New authentication system. The internal authentication system
548 has been almost completely rewritten. Most of the changes are
549 internal, but the new auth system is also very configurable.
551 4) New default filename mangling system.
553 5) A new "net" command has been added. It is somewhat similar to
554 the "net" command in windows. Eventually we plan to replace
555 numerous other utilities (such as smbpasswd) with subcommands
558 6) Samba now negotiates NT-style status32 codes on the wire. This
559 improves error handling a lot.
561 7) Better Windows 2000/XP/2003 printing support including publishing
562 printer attributes in active directory.
564 8) New loadable module support for passdb backends and character
567 9) New default dual-daemon winbindd support for better performance.
569 10) Support for migrating from a Windows NT 4.0 domain to a Samba
570 domain and maintaining user, group and domain SIDs.
572 11) Support for establishing trust relationships with Windows NT 4.0
575 12) Initial support for a distributed Winbind architecture using
576 an LDAP directory for storing SID to uid/gid mappings.
578 13) Major updates to the Samba documentation tree.
580 14) Full support for client and server SMB signing to ensure
581 compatibility with default Windows 2003 security settings.
583 15) Improvement of ACL mapping features based on code donated by
587 Plus lots of other improvements!
590 Additional Documentation
591 ------------------------
593 Please refer to Samba documentation tree (included in the docs/
594 subdirectory) for extensive explanations of installing, configuring
595 and maintaining Samba 3.0 servers and clients. It is advised to
596 begin with the Samba-HOWTO-Collection for overviews and specific
597 tasks (the current book is up to approximately 400 pages) and to
598 refer to the various man pages for information on individual options.
600 We are very glad to be able to include the second edition of
601 "Using Samba" by Jay Ts, Robert Eckstein, and David Collier-Brown

610 Upgrading from a previous Samba 3.0 beta
611 ########################################
613 Beginning with Samba 3.0.0beta3, the RID allocation functions
614 have been moved into winbindd. Previously these were handled
615 by each passdb backend. This means that winbindd must be running
616 to automatically allocate RIDs for users and/or groups. Otherwise,
617 smbd will use the 2.2 algorithm for generating new RIDs.
619 If you are using 'passdb backend = tdbsam' with a previous Samba
620 3.0 beta release (or possibly alpha), it may be necessary to
621 move the RID_COUNTER entry from /usr/local/samba/private/passdb.tdb
622 to winbindd_idmap.tdb. To do this:
624 1) Ensure that winbindd_idmap.tdb exists (launch winbindd at least
626 2) build tdbtool by executing 'make tdbtool' in the source/tdb/
628 3) run: (note that 'tdb>' is the tool's prompt for input)
630 root# ./tdbtool /usr/local/samba/private/passdb.tdb
631 tdb> show RID_COUNTER
635 [000] 0A 52 00 00 .R.
637 tdb> move RID_COUNTER /usr/local/samba/var/locks/winbindd_idmap.tdb
641 If you are using 'passdb backend = ldapsam', it will be necessary to
642 store idmap entries in the LDAP directory as well (i.e. idmap backend
643 = ldap). Refer to the 'net idmap' command for more information on
644 migrating SID<->UNIX id mappings from one backend to another.
646 If the RID_COUNTER record does not exist, then these instructions are
647 unneccessary and the new RID_COUNTER record will be correctly generated

653 Upgrading from Samba 2.2
654 ########################
656 This section is provided to help administrators understand the details
657 involved with upgrading a Samba 2.2 server to Samba 3.0.
663 Many of the options to the GNU autoconf script have been modified
664 in the 3.0 release. The most noticeable are:
666 * removal of --with-tdbsam (is now included by default; see section
667 on passdb backends and authentication for more details)
669 * --with-ldapsam is now on used to provided backward compatible
670 parameters for LDAP enabled Samba 2.2 servers. Refer to the passdb
671 backend and authentication section for more details
673 * inclusion of non-standard passdb modules may be enabled using
674 --with-expsam. This includes an XML backend and a mysql backend.
676 * removal of --with-msdfs (is now enabled by default)
678 * removal of --with-ssl (no longer supported)
680 * --with-utmp now defaults to 'yes' on supported systems
682 * --with-sendfile-support is now enabled by default on supported
689 This section contains a brief listing of changes to smb.conf options
690 in the 3.0.0 release. Please refer to the smb.conf(5) man page for
691 complete descriptions of new or modified parameters.

823 This section contains brief descriptions of any new databases
824 introduced in Samba 3.0. Please remember to backup your existing
825 ${lock directory}/*tdb before upgrading to Samba 3.0. Samba will
826 upgrade databases as they are opened (if necessary), but downgrading
827 from 3.0 to 2.2 is an unsupported path.
829 Name Description Backup?
830 ---- ----------- -------
831 account_policy User policy settings yes
832 gencache Generic caching db no
833 group_mapping Mapping table from Windows yes
834 groups/SID to unix groups
835 winbindd_idmap ID map table from SIDS to UNIX yes
837 namecache Name resolution cache entries no
838 netsamlogon_cache Cache of NET_USER_INFO_3 structure no
839 returned as part of a successful
840 net_sam_logon request
841 printing/*.tdb Cached output from 'lpq no
842 command' created on a per print
844 registry Read-only samba registry skeleton no
845 that provides support for exporting
846 various db tables via the winreg RPCs
852 The following issues are known changes in behavior between Samba 2.2 and
853 Samba 3.0 that may affect certain installations of Samba.
855 1) When operating as a member of a Windows domain, Samba 2.2 would
856 map any users authenticated by the remote DC to the 'guest account'
857 if a uid could not be obtained via the getpwnam() call. Samba 3.0
858 rejects the connection as NT_STATUS_LOGON_FAILURE. There is no
859 current work around to re-establish the 2.2 behavior.
861 2) When adding machines to a Samba 2.2 controlled domain, the
862 'add user script' was used to create the UNIX identity of the
863 machine trust account. Samba 3.0 introduces a new 'add machine
864 script' that must be specified for this purpose. Samba 3.0 will
865 not fall back to using the 'add user script' in the absence of
866 an 'add machine script'
869 ######################################################################
870 Passdb Backends and Authentication
871 ##################################
873 There have been a few new changes that Samba administrators should be
874 aware of when moving to Samba 3.0.
876 1) encrypted passwords have been enabled by default in order to
877 inter-operate better with out-of-the-box Windows client
878 installations. This does mean that either (a) a samba account
879 must be created for each user, or (b) 'encrypt passwords = no'
880 must be explicitly defined in smb.conf.
882 2) Inclusion of new 'security = ads' option for integration
883 with an Active Directory domain using the native Windows
884 Kerberos 5 and LDAP protocols.
886 MIT kerberos 1.3.1 supports the ARCFOUR-HMAC-MD5 encryption
887 type which is neccessary for servers on which the
888 administrator password has not been changed, or kerberos-enabled
889 SMB connections to servers that require Kerberos SMB signing.
890 Besides this one difference, either MIT or Heimdal Kerberos
891 distributions are usable by Samba 3.0.
894 Samba 3.0 also includes the possibility of setting up chains
895 of authentication methods (auth methods) and account storage
896 backends (passdb backend). Please refer to the smb.conf(5)
897 man page for details. While both parameters assume sane default
898 values, it is likely that you will need to understand what the
899 values actually mean in order to ensure Samba operates correctly.
901 The recommended passdb backends at this time are
903 * smbpasswd - 2.2 compatible flat file format
904 * tdbsam - attribute rich database intended as an smbpasswd
905 replacement for stand alone servers
906 * ldapsam - attribute rich account storage and retrieval
907 backend utilizing an LDAP directory.
908 * ldapsam_compat - a 2.2 backward compatible LDAP account
911 Certain functions of the smbpasswd(8) tool have been split between the
912 new smbpasswd(8) utility, the net(8) tool, and the new pdbedit(8)
913 utility. See the respective man pages for details.
916 ######################################################################
920 This section outlines the new features affecting Samba / LDAP
926 A new object class (sambaSamAccount) has been introduced to replace
927 the old sambaAccount. This change aids us in the renaming of attributes
928 to prevent clashes with attributes from other vendors. There is a
929 conversion script (examples/LDAP/convertSambaAccount) to modify and LDIF
930 file to the new schema.
934 $ ldapsearch .... -b "ou=people,dc=..." > old.ldif
935 $ convertSambaAccount <DOM SID> old.ldif new.ldif
937 The <DOM SID> can be obtained by running 'net getlocalsid <DOMAINNAME>'
938 on the Samba PDC as root.
940 The old sambaAccount schema may still be used by specifying the
941 "ldapsam_compat" passdb backend. However, the sambaAccount and
942 associated attributes have been moved to the historical section of
943 the schema file and must be uncommented before use if needed.
944 The 2.2 object class declaration for a sambaAccount has not changed
945 in the 3.0 samba.schema file.
947 Other new object classes and their uses include:
949 * sambaDomain - domain information used to allocate rids
950 for users and groups as necessary. The attributes are added
951 in 'ldap suffix' directory entry automatically if
952 an idmap uid/gid range has been set and the 'ldapsam'
953 passdb backend has been selected.
955 * sambaGroupMapping - an object representing the
956 relationship between a posixGroup and a Windows
957 group/SID. These entries are stored in the 'ldap
958 group suffix' and managed by the 'net groupmap' command.
960 * sambaUnixIdPool - created in the 'ldap idmap suffix' entry
961 automatically and contains the next available 'idmap uid' and
964 * sambaIdmapEntry - object storing a mapping between a
965 SID and a UNIX uid/gid. These objects are created by the
966 idmap_ldap module as needed.
968 * sambaSidEntry - object representing a SID alone, as a Structural
969 class on which to build the sambaIdmapEntry.
972 New Suffix for Searching
973 ------------------------
975 The following new smb.conf parameters have been added to aid in directing
976 certain LDAP queries when 'passdb backend = ldapsam://...' has been
979 * ldap suffix - used to search for user and computer accounts
980 * ldap user suffix - used to store user accounts
981 * ldap machine suffix - used to store machine trust accounts
982 * ldap group suffix - location of posixGroup/sambaGroupMapping entries
983 * ldap idmap suffix - location of sambaIdmapEntry objects
985 If an 'ldap suffix' is defined, it will be appended to all of the
986 remaining sub-suffix parameters. In this case, the order of the suffix
987 listings in smb.conf is important. Always place the 'ldap suffix' first
990 Due to a limitation in Samba's smb.conf parsing, you should not surround
991 the DN's with quotation marks.
997 Samba 3.0 supports an ldap backend for the idmap subsystem. The
998 following options would inform Samba that the idmap table should be
999 stored on the directory server onterose in the "ou=idmap,dc=plainjoe,
1004 idmap backend = ldap:ldap://onterose/
1005 ldap idmap suffix = ou=idmap,dc=plainjoe,dc=org
1006 idmap uid = 40000-50000
1007 idmap gid = 40000-50000
1009 This configuration allows winbind installations on multiple servers to
1010 share a uid/gid number space, thus avoiding the interoperability problems
1011 with NFS that were present in Samba 2.2.
1015 ######################################################################
1016 Trust Relationships and a Samba Domain
1017 ######################################
1019 Samba 3.0.0beta2 is able to utilize winbindd as the means of
1020 allocating uids and gids to trusted users and groups. More
1021 information regarding Samba's support for establishing trust
1022 relationships can be found in the Samba-HOWTO-Collection included
1023 in the docs/ directory of this release.
1025 First create your Samba PDC and ensure that everything is
1026 working correctly before moving on the trusts.
1028 To establish Samba as the trusting domain (named SAMBA) from a Windows NT
1029 4.0 domain named WINDOWS:
1031 1) create the trust account for SAMBA in "User Manager for Domains"
1032 2) connect the trust from the Samba domain using
1033 'net rpc trustdom establish GLASS'
1035 To create a trustlationship with SAMBA as the trusted domain:
1037 1) create the initial trust account for GLASS using
1038 'smbpasswd -a -i GLASS'. You may need to create a UNIX
1039 account for GLASS$ prior to this step (depending on your
1040 local configuration).
1041 2) connect the trust from a WINDOWS DC using "User Manager
1044 Now join winbindd on the Samba PDC to the SAMBA domain using
1045 the normal steps for adding a Samba server to an NT4 domain:
1046 (note that smbd & nmbd must be running at this point)
1048 root# net rpc join -U root
1049 Password: <enter root password from smbpasswd file here>
1051 Start winbindd and test the join with 'wbinfo -t'.
1053 Now test the trust relationship by connecting to the SAMBA DC
1054 (e.g. POGO) as a user from the WINDOWS domain:
1056 $ smbclient //pogo/netlogon -U Administrator -W WINDOWS
1059 Now connect to the WINDOWS DC (e.g. CRYSTAL) as a Samba user:
1061 $ smbclient //crystal/netlogon -U root -W WINDOWS
1064 ######################################################################
1068 Beginning with Samba3.0.0beta3, winbindd has been given new account
1069 manage functionality equivalent to the 'add user script' family of
1070 smb.conf parameters. The idmap design has also been changed to
1071 centralize control of foreign SID lookups and matching to UNIX
1075 Brief Description of Changes
1076 ----------------------------
1078 1) The sid_to_uid() family of functions (smbd/uid.c) have been
1079 reverted to the 2.2.x design. This means that when resolving a
1080 SID to a UID or similar mapping:
1082 a) First consult winbindd
1083 b) perform a local lookup only if winbindd fails to
1084 return a successful answer
1086 There are some variations to this, but these two rules generally
1089 2) All idmap lookups have been moved into winbindd. This means that
1090 a server must run winbindd (and support NSS) in order to achieve
1091 any mappings of SID to dynamically allocated UNIX ids. This was
1092 a conscious design choice.
1094 3) New functions have been added to winbindd to emulate the 'add user
1095 script' family of smbd functions without requiring that external
1096 scripts be defined. This functionality is controlled by the 'winbind
1097 enable local accounts' smb.conf parameter (enabled by default).
1099 However, this account management functionality is only supported
1100 in a local tdb (winbindd_idmap.tdb). If these new UNIX accounts
1101 must be shared among multiple Samba servers (such as a PDC and BDCs),
1102 it will be necessary to define your own 'add user script', et. al.
1103 programs that place the accounts/groups in some form of directory
1104 such as NIS or LDAP. This requirement was deemed beyond the scope
1105 of winbind's account management functions. Solutions for
1106 distributing UNIX system information have been deployed and tested
1107 for many years. We saw no need to reinvent the wheel.
1109 4) A member of a Samba controlled domain running winbindd is now able
1110 to map domain users directly onto existing UNIX accounts while still
1111 automatically creating accounts for trusted users and groups. This
1112 behavior is controlled by the 'winbind trusted domains only' smb.conf
1113 parameter (disabled by default to provide 2.2.x winbind behavior).
1115 5) Group mapping support is wrapped in the local_XX_to_XX() functions
1116 in smbd/uid.c. The reason that group mappings are not included
1117 in winbindd is because the purpose of Samba's group map is to
1118 match any Windows SID with an existing UNIX group. These UNIX
1119 groups can be created by winbindd (see next section), but the
1120 SID<->gid mapping is retreived by smbd, not winbindd.
1126 * security = server running winbindd to allocate accounts on demand
1128 * Samba PDC running winbindd to handle the automatic creation of UNIX
1129 identities for machine trust accounts
1131 * Automtically creating UNIX user and groups when migrating a Windows NT
1132 4.0 PDC to a Samba PDC. Winbindd must be running when executing
1133 'net rpc vampire' for this to work.
