351 o Correct the "smbldap_open: cannot access when not root error"
352 messages when looking up group information (bug 281).

374 around issues with establishing trusts to a Windows 2003 domain.
375 o Ensure we mangle names ending in '.' in hash2 mangling method.
376 o Correct parsing issues with munged dial string.
377 o Fix bugs in quota support for XFS.
378 o Add a cleaner method for applications that need to provide
379 name->SID mappings to do this via NSS rather than having to
380 know the winbindd pipe protocol.
381 o Adds a variant of the winbindd_getgroups() call called
382 winbindd_getusersids() that provides direct SID->SIDs listing of
383 a users supplementary groups. This is enough to allow non-Samba
384 applications to do ACL checking.
385 o Make sure we don't append the 'ldap suffix' when writing out the
386 'ldap XXX suffix' values in SWAT (bug 328).
387 o Fix renames across file systems.

407 to "smbprn.00000033 Test Page" so that we can get the smb
408 jobid back. This allow users to delete jobs with cups printing
409 backend (partial work on bug 770).
410 o Fix build of winbindd with static pdb modules.
411 o Retrieve the correct ACL group bits if the file has an ACL
413 o Implement "net rpc group members": Get members of a domain group
414 in human-readable format.
415 o Add MacOSX (Darwin) specific charset module code.

473 ######################################################################
475 =======================================
476 The original 3.0.0 release notes follow
477 =======================================
483 1) Active Directory support. Samba 3.0 is now able to
484 join a ADS realm as a member server and authenticate
485 users using LDAP/Kerberos.
487 2) Unicode support. Samba will now negotiate UNICODE on the wire
488 and internally there is now a much better infrastructure for
489 multi-byte and UNICODE character sets.
491 3) New authentication system. The internal authentication system
492 has been almost completely rewritten. Most of the changes are
493 internal, but the new auth system is also very configurable.
495 4) New default filename mangling system.
497 5) A new "net" command has been added. It is somewhat similar to
498 the "net" command in windows. Eventually we plan to replace
499 numerous other utilities (such as smbpasswd) with subcommands
502 6) Samba now negotiates NT-style status32 codes on the wire. This
503 improves error handling a lot.
505 7) Better Windows 2000/XP/2003 printing support including publishing
506 printer attributes in active directory.
508 8) New loadable module support for passdb backends and character
511 9) New default dual-daemon winbindd support for better performance.
513 10) Support for migrating from a Windows NT 4.0 domain to a Samba
514 domain and maintaining user, group and domain SIDs.
516 11) Support for establishing trust relationships with Windows NT 4.0
519 12) Initial support for a distributed Winbind architecture using
520 an LDAP directory for storing SID to uid/gid mappings.
522 13) Major updates to the Samba documentation tree.
524 14) Full support for client and server SMB signing to ensure
525 compatibility with default Windows 2003 security settings.
527 15) Improvement of ACL mapping features based on code donated by
531 Plus lots of other improvements!
534 Additional Documentation
535 ------------------------
537 Please refer to Samba documentation tree (included in the docs/
538 subdirectory) for extensive explanations of installing, configuring
539 and maintaining Samba 3.0 servers and clients. It is advised to
540 begin with the Samba-HOWTO-Collection for overviews and specific
541 tasks (the current book is up to approximately 400 pages) and to
542 refer to the various man pages for information on individual options.
544 We are very glad to be able to include the second edition of
545 "Using Samba" by Jay Ts, Robert Eckstein, and David Collier-Brown
546 (O'Reilly & Associates) in this release. The book is available
547 on-line at http://samba.org/samba/docs/ and is included with
548 the Samba Web Administration Tool (SWAT). Thanks to the authors and
549 publisher for making "Using Samba" under the GNU Free Documentation
553 ######################################################################
554 Upgrading from a previous Samba 3.0 beta
555 ########################################
557 Beginning with Samba 3.0.0beta3, the RID allocation functions
558 have been moved into winbindd. Previously these were handled
559 by each passdb backend. This means that winbindd must be running
560 to automatically allocate RIDs for users and/or groups. Otherwise,
561 smbd will use the 2.2 algorithm for generating new RIDs.
563 If you are using 'passdb backend = tdbsam' with a previous Samba
564 3.0 beta release (or possibly alpha), it may be necessary to
565 move the RID_COUNTER entry from /usr/local/samba/private/passdb.tdb
566 to winbindd_idmap.tdb. To do this:
568 1) Ensure that winbindd_idmap.tdb exists (launch winbindd at least
570 2) build tdbtool by executing 'make tdbtool' in the source/tdb/
572 3) run: (note that 'tdb>' is the tool's prompt for input)
574 root# ./tdbtool /usr/local/samba/private/passdb.tdb
575 tdb> show RID_COUNTER
579 [000] 0A 52 00 00 .R.
581 tdb> move RID_COUNTER /usr/local/samba/var/locks/winbindd_idmap.tdb
585 If you are using 'passdb backend = ldapsam', it will be necessary to
586 store idmap entries in the LDAP directory as well (i.e. idmap backend
587 = ldap). Refer to the 'net idmap' command for more information on
588 migrating SID<->UNIX id mappings from one backend to another.
590 If the RID_COUNTER record does not exist, then these instructions are
591 unneccessary and the new RID_COUNTER record will be correctly generated

597 Upgrading from Samba 2.2
598 ########################
600 This section is provided to help administrators understand the details
601 involved with upgrading a Samba 2.2 server to Samba 3.0.
607 Many of the options to the GNU autoconf script have been modified
608 in the 3.0 release. The most noticeable are:
610 * removal of --with-tdbsam (is now included by default; see section
611 on passdb backends and authentication for more details)

767 This section contains brief descriptions of any new databases
768 introduced in Samba 3.0. Please remember to backup your existing
769 ${lock directory}/*tdb before upgrading to Samba 3.0. Samba will
770 upgrade databases as they are opened (if necessary), but downgrading
771 from 3.0 to 2.2 is an unsupported path.
773 Name Description Backup?
774 ---- ----------- -------
775 account_policy User policy settings yes
776 gencache Generic caching db no
777 group_mapping Mapping table from Windows yes
778 groups/SID to unix groups
779 winbindd_idmap ID map table from SIDS to UNIX yes
781 namecache Name resolution cache entries no
782 netsamlogon_cache Cache of NET_USER_INFO_3 structure no

785 printing/*.tdb Cached output from 'lpq no
786 command' created on a per print
788 registry Read-only samba registry skeleton no
789 that provides support for exporting
790 various db tables via the winreg RPCs
796 The following issues are known changes in behavior between Samba 2.2 and
797 Samba 3.0 that may affect certain installations of Samba.
799 1) When operating as a member of a Windows domain, Samba 2.2 would
800 map any users authenticated by the remote DC to the 'guest account'
801 if a uid could not be obtained via the getpwnam() call. Samba 3.0
802 rejects the connection as NT_STATUS_LOGON_FAILURE. There is no
803 current work around to re-establish the 2.2 behavior.
805 2) When adding machines to a Samba 2.2 controlled domain, the
806 'add user script' was used to create the UNIX identity of the
807 machine trust account. Samba 3.0 introduces a new 'add machine
808 script' that must be specified for this purpose. Samba 3.0 will
809 not fall back to using the 'add user script' in the absence of
810 an 'add machine script'
813 ######################################################################
814 Passdb Backends and Authentication
815 ##################################
817 There have been a few new changes that Samba administrators should be
818 aware of when moving to Samba 3.0.
820 1) encrypted passwords have been enabled by default in order to
821 inter-operate better with out-of-the-box Windows client
822 installations. This does mean that either (a) a samba account
823 must be created for each user, or (b) 'encrypt passwords = no'
824 must be explicitly defined in smb.conf.
826 2) Inclusion of new 'security = ads' option for integration
827 with an Active Directory domain using the native Windows
828 Kerberos 5 and LDAP protocols.
830 MIT kerberos 1.3.1 supports the ARCFOUR-HMAC-MD5 encryption
831 type which is neccessary for servers on which the
832 administrator password has not been changed, or kerberos-enabled
833 SMB connections to servers that require Kerberos SMB signing.
834 Besides this one difference, either MIT or Heimdal Kerberos
835 distributions are usable by Samba 3.0.
838 Samba 3.0 also includes the possibility of setting up chains
839 of authentication methods (auth methods) and account storage
840 backends (passdb backend). Please refer to the smb.conf(5)
841 man page for details. While both parameters assume sane default
842 values, it is likely that you will need to understand what the
843 values actually mean in order to ensure Samba operates correctly.
845 The recommended passdb backends at this time are
847 * smbpasswd - 2.2 compatible flat file format
848 * tdbsam - attribute rich database intended as an smbpasswd
849 replacement for stand alone servers
850 * ldapsam - attribute rich account storage and retrieval
851 backend utilizing an LDAP directory.
852 * ldapsam_compat - a 2.2 backward compatible LDAP account
855 Certain functions of the smbpasswd(8) tool have been split between the
856 new smbpasswd(8) utility, the net(8) tool, and the new pdbedit(8)
857 utility. See the respective man pages for details.
860 ######################################################################
864 This section outlines the new features affecting Samba / LDAP
870 A new object class (sambaSamAccount) has been introduced to replace
871 the old sambaAccount. This change aids us in the renaming of attributes
872 to prevent clashes with attributes from other vendors. There is a
873 conversion script (examples/LDAP/convertSambaAccount) to modify and LDIF
874 file to the new schema.
878 $ ldapsearch .... -b "ou=people,dc=..." > old.ldif
879 $ convertSambaAccount <DOM SID> old.ldif new.ldif
881 The <DOM SID> can be obtained by running 'net getlocalsid <DOMAINNAME>'
882 on the Samba PDC as root.
884 The old sambaAccount schema may still be used by specifying the
885 "ldapsam_compat" passdb backend. However, the sambaAccount and
886 associated attributes have been moved to the historical section of
887 the schema file and must be uncommented before use if needed.
888 The 2.2 object class declaration for a sambaAccount has not changed
889 in the 3.0 samba.schema file.
891 Other new object classes and their uses include:
893 * sambaDomain - domain information used to allocate rids
894 for users and groups as necessary. The attributes are added
895 in 'ldap suffix' directory entry automatically if
896 an idmap uid/gid range has been set and the 'ldapsam'
897 passdb backend has been selected.
899 * sambaGroupMapping - an object representing the
900 relationship between a posixGroup and a Windows
901 group/SID. These entries are stored in the 'ldap
902 group suffix' and managed by the 'net groupmap' command.
904 * sambaUnixIdPool - created in the 'ldap idmap suffix' entry
905 automatically and contains the next available 'idmap uid' and
908 * sambaIdmapEntry - object storing a mapping between a
909 SID and a UNIX uid/gid. These objects are created by the
910 idmap_ldap module as needed.
912 * sambaSidEntry - object representing a SID alone, as a Structural
913 class on which to build the sambaIdmapEntry.
916 New Suffix for Searching
917 ------------------------
919 The following new smb.conf parameters have been added to aid in directing
920 certain LDAP queries when 'passdb backend = ldapsam://...' has been
923 * ldap suffix - used to search for user and computer accounts
924 * ldap user suffix - used to store user accounts
925 * ldap machine suffix - used to store machine trust accounts
926 * ldap group suffix - location of posixGroup/sambaGroupMapping entries
927 * ldap idmap suffix - location of sambaIdmapEntry objects
929 If an 'ldap suffix' is defined, it will be appended to all of the
930 remaining sub-suffix parameters. In this case, the order of the suffix
931 listings in smb.conf is important. Always place the 'ldap suffix' first
934 Due to a limitation in Samba's smb.conf parsing, you should not surround
935 the DN's with quotation marks.
941 Samba 3.0 supports an ldap backend for the idmap subsystem. The
942 following options would inform Samba that the idmap table should be
943 stored on the directory server onterose in the "ou=idmap,dc=plainjoe,
948 idmap backend = ldap:ldap://onterose/
949 ldap idmap suffix = ou=idmap,dc=plainjoe,dc=org
950 idmap uid = 40000-50000
951 idmap gid = 40000-50000
953 This configuration allows winbind installations on multiple servers to
954 share a uid/gid number space, thus avoiding the interoperability problems
955 with NFS that were present in Samba 2.2.
959 ######################################################################
960 Trust Relationships and a Samba Domain
961 ######################################
963 Samba 3.0.0beta2 is able to utilize winbindd as the means of
964 allocating uids and gids to trusted users and groups. More
965 information regarding Samba's support for establishing trust
966 relationships can be found in the Samba-HOWTO-Collection included
967 in the docs/ directory of this release.
969 First create your Samba PDC and ensure that everything is
970 working correctly before moving on the trusts.
972 To establish Samba as the trusting domain (named SAMBA) from a Windows NT
973 4.0 domain named WINDOWS:
975 1) create the trust account for SAMBA in "User Manager for Domains"
976 2) connect the trust from the Samba domain using
977 'net rpc trustdom establish GLASS'
979 To create a trustlationship with SAMBA as the trusted domain:
981 1) create the initial trust account for GLASS using
982 'smbpasswd -a -i GLASS'. You may need to create a UNIX
983 account for GLASS$ prior to this step (depending on your
984 local configuration).
985 2) connect the trust from a WINDOWS DC using "User Manager
988 Now join winbindd on the Samba PDC to the SAMBA domain using
989 the normal steps for adding a Samba server to an NT4 domain:
990 (note that smbd & nmbd must be running at this point)
992 root# net rpc join -U root
993 Password: <enter root password from smbpasswd file here>
995 Start winbindd and test the join with 'wbinfo -t'.
997 Now test the trust relationship by connecting to the SAMBA DC
998 (e.g. POGO) as a user from the WINDOWS domain:
1000 $ smbclient //pogo/netlogon -U Administrator -W WINDOWS
1003 Now connect to the WINDOWS DC (e.g. CRYSTAL) as a Samba user:
1005 $ smbclient //crystal/netlogon -U root -W WINDOWS
1008 ######################################################################
1012 Beginning with Samba3.0.0beta3, winbindd has been given new account
1013 manage functionality equivalent to the 'add user script' family of
1014 smb.conf parameters. The idmap design has also been changed to
1015 centralize control of foreign SID lookups and matching to UNIX
1019 Brief Description of Changes
1020 ----------------------------
1022 1) The sid_to_uid() family of functions (smbd/uid.c) have been
1023 reverted to the 2.2.x design. This means that when resolving a
1024 SID to a UID or similar mapping:
1026 a) First consult winbindd
1027 b) perform a local lookup only if winbindd fails to
1028 return a successful answer
1030 There are some variations to this, but these two rules generally
1033 2) All idmap lookups have been moved into winbindd. This means that
1034 a server must run winbindd (and support NSS) in order to achieve
1035 any mappings of SID to dynamically allocated UNIX ids. This was
1036 a conscious design choice.
1038 3) New functions have been added to winbindd to emulate the 'add user
1039 script' family of smbd functions without requiring that external
1040 scripts be defined. This functionality is controlled by the 'winbind
1041 enable local accounts' smb.conf parameter (enabled by default).
1043 However, this account management functionality is only supported
1044 in a local tdb (winbindd_idmap.tdb). If these new UNIX accounts
1045 must be shared among multiple Samba servers (such as a PDC and BDCs),
1046 it will be necessary to define your own 'add user script', et. al.
1047 programs that place the accounts/groups in some form of directory
1048 such as NIS or LDAP. This requirement was deemed beyond the scope
1049 of winbind's account management functions. Solutions for
1050 distributing UNIX system information have been deployed and tested
1051 for many years. We saw no need to reinvent the wheel.
1053 4) A member of a Samba controlled domain running winbindd is now able
1054 to map domain users directly onto existing UNIX accounts while still
1055 automatically creating accounts for trusted users and groups. This
1056 behavior is controlled by the 'winbind trusted domains only' smb.conf
1057 parameter (disabled by default to provide 2.2.x winbind behavior).
1059 5) Group mapping support is wrapped in the local_XX_to_XX() functions
1060 in smbd/uid.c. The reason that group mappings are not included
1061 in winbindd is because the purpose of Samba's group map is to
1062 match any Windows SID with an existing UNIX group. These UNIX
1063 groups can be created by winbindd (see next section), but the
1064 SID<->gid mapping is retreived by smbd, not winbindd.
1070 * security = server running winbindd to allocate accounts on demand
1072 * Samba PDC running winbindd to handle the automatic creation of UNIX
1073 identities for machine trust accounts
1075 * Automtically creating UNIX user and groups when migrating a Windows NT
1076 4.0 PDC to a Samba PDC. Winbindd must be running when executing
1077 'net rpc vampire' for this to work.
