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

489 'ldap XXX suffix' values in SWAT (bug 328).
490 o Fix renames across file systems.

576 ######################################################################
578 =======================================
579 The original 3.0.0 release notes follow
580 =======================================
586 1) Active Directory support. Samba 3.0 is now able to
587 join a ADS realm as a member server and authenticate
588 users using LDAP/Kerberos.
590 2) Unicode support. Samba will now negotiate UNICODE on the wire
591 and internally there is now a much better infrastructure for
592 multi-byte and UNICODE character sets.
594 3) New authentication system. The internal authentication system
595 has been almost completely rewritten. Most of the changes are
596 internal, but the new auth system is also very configurable.
598 4) New default filename mangling system.
600 5) A new "net" command has been added. It is somewhat similar to
601 the "net" command in windows. Eventually we plan to replace
602 numerous other utilities (such as smbpasswd) with subcommands
605 6) Samba now negotiates NT-style status32 codes on the wire. This
606 improves error handling a lot.
608 7) Better Windows 2000/XP/2003 printing support including publishing
609 printer attributes in active directory.

637 Additional Documentation
638 ------------------------
640 Please refer to Samba documentation tree (included in the docs/
641 subdirectory) for extensive explanations of installing, configuring
642 and maintaining Samba 3.0 servers and clients. It is advised to
643 begin with the Samba-HOWTO-Collection for overviews and specific
644 tasks (the current book is up to approximately 400 pages) and to
645 refer to the various man pages for information on individual options.
647 We are very glad to be able to include the second edition of
648 "Using Samba" by Jay Ts, Robert Eckstein, and David Collier-Brown
649 (O'Reilly & Associates) in this release. The book is available
650 on-line at http://samba.org/samba/docs/ and is included with
651 the Samba Web Administration Tool (SWAT). Thanks to the authors and
652 publisher for making "Using Samba" under the GNU Free Documentation

657 Upgrading from a previous Samba 3.0 beta
658 ########################################
660 Beginning with Samba 3.0.0beta3, the RID allocation functions
661 have been moved into winbindd. Previously these were handled
662 by each passdb backend. This means that winbindd must be running
663 to automatically allocate RIDs for users and/or groups. Otherwise,
664 smbd will use the 2.2 algorithm for generating new RIDs.
666 If you are using 'passdb backend = tdbsam' with a previous Samba
667 3.0 beta release (or possibly alpha), it may be necessary to
668 move the RID_COUNTER entry from /usr/local/samba/private/passdb.tdb
669 to winbindd_idmap.tdb. To do this:
671 1) Ensure that winbindd_idmap.tdb exists (launch winbindd at least
673 2) build tdbtool by executing 'make tdbtool' in the source/tdb/
675 3) run: (note that 'tdb>' is the tool's prompt for input)
677 root# ./tdbtool /usr/local/samba/private/passdb.tdb
678 tdb> show RID_COUNTER
682 [000] 0A 52 00 00 .R.
684 tdb> move RID_COUNTER /usr/local/samba/var/locks/winbindd_idmap.tdb
688 If you are using 'passdb backend = ldapsam', it will be necessary to
689 store idmap entries in the LDAP directory as well (i.e. idmap backend
690 = ldap). Refer to the 'net idmap' command for more information on
691 migrating SID<->UNIX id mappings from one backend to another.
693 If the RID_COUNTER record does not exist, then these instructions are
694 unneccessary and the new RID_COUNTER record will be correctly generated

870 This section contains brief descriptions of any new databases
871 introduced in Samba 3.0. Please remember to backup your existing
872 ${lock directory}/*tdb before upgrading to Samba 3.0. Samba will
873 upgrade databases as they are opened (if necessary), but downgrading
874 from 3.0 to 2.2 is an unsupported path.
876 Name Description Backup?
877 ---- ----------- -------
878 account_policy User policy settings yes
879 gencache Generic caching db no
880 group_mapping Mapping table from Windows yes
881 groups/SID to unix groups
882 winbindd_idmap ID map table from SIDS to UNIX yes
884 namecache Name resolution cache entries no
885 netsamlogon_cache Cache of NET_USER_INFO_3 structure no

889 command' created on a per print
891 registry Read-only samba registry skeleton no
892 that provides support for exporting
893 various db tables via the winreg RPCs
899 The following issues are known changes in behavior between Samba 2.2 and
900 Samba 3.0 that may affect certain installations of Samba.
902 1) When operating as a member of a Windows domain, Samba 2.2 would
903 map any users authenticated by the remote DC to the 'guest account'
904 if a uid could not be obtained via the getpwnam() call. Samba 3.0
905 rejects the connection as NT_STATUS_LOGON_FAILURE. There is no
906 current work around to re-establish the 2.2 behavior.
908 2) When adding machines to a Samba 2.2 controlled domain, the
909 'add user script' was used to create the UNIX identity of the
910 machine trust account. Samba 3.0 introduces a new 'add machine
911 script' that must be specified for this purpose. Samba 3.0 will
912 not fall back to using the 'add user script' in the absence of
913 an 'add machine script'
916 ######################################################################
917 Passdb Backends and Authentication
918 ##################################
920 There have been a few new changes that Samba administrators should be
921 aware of when moving to Samba 3.0.
923 1) encrypted passwords have been enabled by default in order to
924 inter-operate better with out-of-the-box Windows client
925 installations. This does mean that either (a) a samba account
926 must be created for each user, or (b) 'encrypt passwords = no'
927 must be explicitly defined in smb.conf.
929 2) Inclusion of new 'security = ads' option for integration
930 with an Active Directory domain using the native Windows
931 Kerberos 5 and LDAP protocols.
933 MIT kerberos 1.3.1 supports the ARCFOUR-HMAC-MD5 encryption
934 type which is neccessary for servers on which the
935 administrator password has not been changed, or kerberos-enabled
936 SMB connections to servers that require Kerberos SMB signing.
937 Besides this one difference, either MIT or Heimdal Kerberos
938 distributions are usable by Samba 3.0.
941 Samba 3.0 also includes the possibility of setting up chains
942 of authentication methods (auth methods) and account storage
943 backends (passdb backend). Please refer to the smb.conf(5)
944 man page for details. While both parameters assume sane default
945 values, it is likely that you will need to understand what the
946 values actually mean in order to ensure Samba operates correctly.
948 The recommended passdb backends at this time are
950 * smbpasswd - 2.2 compatible flat file format
951 * tdbsam - attribute rich database intended as an smbpasswd
952 replacement for stand alone servers
953 * ldapsam - attribute rich account storage and retrieval
954 backend utilizing an LDAP directory.
955 * ldapsam_compat - a 2.2 backward compatible LDAP account
958 Certain functions of the smbpasswd(8) tool have been split between the
959 new smbpasswd(8) utility, the net(8) tool, and the new pdbedit(8)
960 utility. See the respective man pages for details.
963 ######################################################################
967 This section outlines the new features affecting Samba / LDAP
973 A new object class (sambaSamAccount) has been introduced to replace
974 the old sambaAccount. This change aids us in the renaming of attributes
975 to prevent clashes with attributes from other vendors. There is a
976 conversion script (examples/LDAP/convertSambaAccount) to modify and LDIF
977 file to the new schema.
981 $ ldapsearch .... -b "ou=people,dc=..." > old.ldif
982 $ convertSambaAccount <DOM SID> old.ldif new.ldif
984 The <DOM SID> can be obtained by running 'net getlocalsid <DOMAINNAME>'
985 on the Samba PDC as root.
987 The old sambaAccount schema may still be used by specifying the
988 "ldapsam_compat" passdb backend. However, the sambaAccount and
989 associated attributes have been moved to the historical section of
990 the schema file and must be uncommented before use if needed.
991 The 2.2 object class declaration for a sambaAccount has not changed
992 in the 3.0 samba.schema file.
994 Other new object classes and their uses include:
996 * sambaDomain - domain information used to allocate rids
997 for users and groups as necessary. The attributes are added
998 in 'ldap suffix' directory entry automatically if
999 an idmap uid/gid range has been set and the 'ldapsam'
1000 passdb backend has been selected.
1002 * sambaGroupMapping - an object representing the
1003 relationship between a posixGroup and a Windows
1004 group/SID. These entries are stored in the 'ldap
1005 group suffix' and managed by the 'net groupmap' command.
1007 * sambaUnixIdPool - created in the 'ldap idmap suffix' entry
1008 automatically and contains the next available 'idmap uid' and
1011 * sambaIdmapEntry - object storing a mapping between a
1012 SID and a UNIX uid/gid. These objects are created by the
1013 idmap_ldap module as needed.
1015 * sambaSidEntry - object representing a SID alone, as a Structural
1016 class on which to build the sambaIdmapEntry.
1019 New Suffix for Searching
1020 ------------------------
1022 The following new smb.conf parameters have been added to aid in directing
1023 certain LDAP queries when 'passdb backend = ldapsam://...' has been
1026 * ldap suffix - used to search for user and computer accounts
1027 * ldap user suffix - used to store user accounts
1028 * ldap machine suffix - used to store machine trust accounts
1029 * ldap group suffix - location of posixGroup/sambaGroupMapping entries
1030 * ldap idmap suffix - location of sambaIdmapEntry objects
1032 If an 'ldap suffix' is defined, it will be appended to all of the
1033 remaining sub-suffix parameters. In this case, the order of the suffix
1034 listings in smb.conf is important. Always place the 'ldap suffix' first
1037 Due to a limitation in Samba's smb.conf parsing, you should not surround
1038 the DN's with quotation marks.
1044 Samba 3.0 supports an ldap backend for the idmap subsystem. The
1045 following options would inform Samba that the idmap table should be
1046 stored on the directory server onterose in the "ou=idmap,dc=plainjoe,
1051 idmap backend = ldap:ldap://onterose/
1052 ldap idmap suffix = ou=idmap,dc=plainjoe,dc=org
1053 idmap uid = 40000-50000
1054 idmap gid = 40000-50000
1056 This configuration allows winbind installations on multiple servers to
1057 share a uid/gid number space, thus avoiding the interoperability problems
1058 with NFS that were present in Samba 2.2.
1062 ######################################################################
1063 Trust Relationships and a Samba Domain
1064 ######################################
1066 Samba 3.0.0beta2 is able to utilize winbindd as the means of
1067 allocating uids and gids to trusted users and groups. More
1068 information regarding Samba's support for establishing trust
1069 relationships can be found in the Samba-HOWTO-Collection included
1070 in the docs/ directory of this release.
1072 First create your Samba PDC and ensure that everything is
1073 working correctly before moving on the trusts.
1075 To establish Samba as the trusting domain (named SAMBA) from a Windows NT
1076 4.0 domain named WINDOWS:
1078 1) create the trust account for SAMBA in "User Manager for Domains"
1079 2) connect the trust from the Samba domain using
1080 'net rpc trustdom establish GLASS'
1082 To create a trustlationship with SAMBA as the trusted domain:
1084 1) create the initial trust account for GLASS using
1085 'smbpasswd -a -i GLASS'. You may need to create a UNIX
1086 account for GLASS$ prior to this step (depending on your
1087 local configuration).
1088 2) connect the trust from a WINDOWS DC using "User Manager
1091 Now join winbindd on the Samba PDC to the SAMBA domain using
1092 the normal steps for adding a Samba server to an NT4 domain:
1093 (note that smbd & nmbd must be running at this point)
1095 root# net rpc join -U root
1096 Password: <enter root password from smbpasswd file here>
1098 Start winbindd and test the join with 'wbinfo -t'.
1100 Now test the trust relationship by connecting to the SAMBA DC
1101 (e.g. POGO) as a user from the WINDOWS domain:
1103 $ smbclient //pogo/netlogon -U Administrator -W WINDOWS
1106 Now connect to the WINDOWS DC (e.g. CRYSTAL) as a Samba user:
1108 $ smbclient //crystal/netlogon -U root -W WINDOWS
1111 ######################################################################
1115 Beginning with Samba3.0.0beta3, winbindd has been given new account
1116 manage functionality equivalent to the 'add user script' family of
1117 smb.conf parameters. The idmap design has also been changed to
1118 centralize control of foreign SID lookups and matching to UNIX
1122 Brief Description of Changes
1123 ----------------------------
1125 1) The sid_to_uid() family of functions (smbd/uid.c) have been
1126 reverted to the 2.2.x design. This means that when resolving a
1127 SID to a UID or similar mapping:
1129 a) First consult winbindd
1130 b) perform a local lookup only if winbindd fails to
1131 return a successful answer
1133 There are some variations to this, but these two rules generally
1136 2) All idmap lookups have been moved into winbindd. This means that
1137 a server must run winbindd (and support NSS) in order to achieve
1138 any mappings of SID to dynamically allocated UNIX ids. This was
1139 a conscious design choice.
1141 3) New functions have been added to winbindd to emulate the 'add user
1142 script' family of smbd functions without requiring that external
1143 scripts be defined. This functionality is controlled by the 'winbind
1144 enable local accounts' smb.conf parameter (enabled by default).
1146 However, this account management functionality is only supported
1147 in a local tdb (winbindd_idmap.tdb). If these new UNIX accounts
1148 must be shared among multiple Samba servers (such as a PDC and BDCs),
1149 it will be necessary to define your own 'add user script', et. al.
1150 programs that place the accounts/groups in some form of directory
1151 such as NIS or LDAP. This requirement was deemed beyond the scope
1152 of winbind's account management functions. Solutions for
1153 distributing UNIX system information have been deployed and tested
1154 for many years. We saw no need to reinvent the wheel.
1156 4) A member of a Samba controlled domain running winbindd is now able
1157 to map domain users directly onto existing UNIX accounts while still
1158 automatically creating accounts for trusted users and groups. This
1159 behavior is controlled by the 'winbind trusted domains only' smb.conf
1160 parameter (disabled by default to provide 2.2.x winbind behavior).
1162 5) Group mapping support is wrapped in the local_XX_to_XX() functions
1163 in smbd/uid.c. The reason that group mappings are not included
1164 in winbindd is because the purpose of Samba's group map is to
1165 match any Windows SID with an existing UNIX group. These UNIX
1166 groups can be created by winbindd (see next section), but the
1167 SID<->gid mapping is retreived by smbd, not winbindd.
1173 * security = server running winbindd to allocate accounts on demand
1175 * Samba PDC running winbindd to handle the automatic creation of UNIX
1176 identities for machine trust accounts
1178 * Automtically creating UNIX user and groups when migrating a Windows NT
1179 4.0 PDC to a Samba PDC. Winbindd must be running when executing
1180 'net rpc vampire' for this to work.
