1 WHATS NEW IN Samba 3.0.2pre1
3 ===============================
5 This is a preview release of the Samba 3.0.2 code base and is
6 provided for testing only. This release is *not* intended for
7 production servers. Use at your own risk.
9 There have been several bug fixes since the 3.0.1 release that
10 we feel are important to make available to the Samba community

339 winbindd pipe protocol.
340 o Adds a variant of the winbindd_getgroups() call called
341 winbindd_getusersids() that provides direct SID->SIDs listing of a
342 users supplementary groups. This is enough to allow non-Samba
343 applications to do ACL checking.

430 ######################################################################
432 =======================================
433 The original 3.0.0 release notes follow
434 =======================================
440 1) Active Directory support. Samba 3.0 is now able to
441 join a ADS realm as a member server and authenticate
442 users using LDAP/Kerberos.
444 2) Unicode support. Samba will now negotiate UNICODE on the wire
445 and internally there is now a much better infrastructure for
446 multi-byte and UNICODE character sets.
448 3) New authentication system. The internal authentication system
449 has been almost completely rewritten. Most of the changes are
450 internal, but the new auth system is also very configurable.
452 4) New default filename mangling system.
454 5) A new "net" command has been added. It is somewhat similar to
455 the "net" command in windows. Eventually we plan to replace
456 numerous other utilities (such as smbpasswd) with subcommands
459 6) Samba now negotiates NT-style status32 codes on the wire. This
460 improves error handling a lot.
462 7) Better Windows 2000/XP/2003 printing support including publishing
463 printer attributes in active directory.
465 8) New loadable module support for passdb backends and character
468 9) New default dual-daemon winbindd support for better performance.
470 10) Support for migrating from a Windows NT 4.0 domain to a Samba
471 domain and maintaining user, group and domain SIDs.
473 11) Support for establishing trust relationships with Windows NT 4.0
476 12) Initial support for a distributed Winbind architecture using
477 an LDAP directory for storing SID to uid/gid mappings.
479 13) Major updates to the Samba documentation tree.
481 14) Full support for client and server SMB signing to ensure
482 compatibility with default Windows 2003 security settings.
484 15) Improvement of ACL mapping features based on code donated by
488 Plus lots of other improvements!
491 Additional Documentation
492 ------------------------
494 Please refer to Samba documentation tree (included in the docs/
495 subdirectory) for extensive explanations of installing, configuring
496 and maintaining Samba 3.0 servers and clients. It is advised to
497 begin with the Samba-HOWTO-Collection for overviews and specific
498 tasks (the current book is up to approximately 400 pages) and to
499 refer to the various man pages for information on individual options.
501 We are very glad to be able to include the second edition of
502 "Using Samba" by Jay Ts, Robert Eckstein, and David Collier-Brown
503 (O'Reilly & Associates) in this release. The book is available
504 on-line at http://samba.org/samba/docs/ and is included with
505 the Samba Web Administration Tool (SWAT). Thanks to the authors and
506 publisher for making "Using Samba" under the GNU Free Documentation
510 ######################################################################
511 Upgrading from a previous Samba 3.0 beta
512 ########################################
514 Beginning with Samba 3.0.0beta3, the RID allocation functions
515 have been moved into winbindd. Previously these were handled
516 by each passdb backend. This means that winbindd must be running
517 to automatically allocate RIDs for users and/or groups. Otherwise,
518 smbd will use the 2.2 algorithm for generating new RIDs.
520 If you are using 'passdb backend = tdbsam' with a previous Samba
521 3.0 beta release (or possibly alpha), it may be necessary to
522 move the RID_COUNTER entry from /usr/local/samba/private/passdb.tdb
523 to winbindd_idmap.tdb. To do this:
525 1) Ensure that winbindd_idmap.tdb exists (launch winbindd at least
527 2) build tdbtool by executing 'make tdbtool' in the source/tdb/
529 3) run: (note that 'tdb>' is the tool's prompt for input)
531 root# ./tdbtool /usr/local/samba/private/passdb.tdb
532 tdb> show RID_COUNTER
536 [000] 0A 52 00 00 .R.
538 tdb> move RID_COUNTER /usr/local/samba/var/locks/winbindd_idmap.tdb
542 If you are using 'passdb backend = ldapsam', it will be necessary to
543 store idmap entries in the LDAP directory as well (i.e. idmap backend
544 = ldap). Refer to the 'net idmap' command for more information on
545 migrating SID<->UNIX id mappings from one backend to another.
547 If the RID_COUNTER record does not exist, then these instructions are
548 unneccessary and the new RID_COUNTER record will be correctly generated

724 This section contains brief descriptions of any new databases
725 introduced in Samba 3.0. Please remember to backup your existing
726 ${lock directory}/*tdb before upgrading to Samba 3.0. Samba will
727 upgrade databases as they are opened (if necessary), but downgrading
728 from 3.0 to 2.2 is an unsupported path.

753 The following issues are known changes in behavior between Samba 2.2 and
754 Samba 3.0 that may affect certain installations of Samba.
756 1) When operating as a member of a Windows domain, Samba 2.2 would
757 map any users authenticated by the remote DC to the 'guest account'
758 if a uid could not be obtained via the getpwnam() call. Samba 3.0
759 rejects the connection as NT_STATUS_LOGON_FAILURE. There is no
760 current work around to re-establish the 2.2 behavior.
762 2) When adding machines to a Samba 2.2 controlled domain, the
763 'add user script' was used to create the UNIX identity of the
764 machine trust account. Samba 3.0 introduces a new 'add machine
765 script' that must be specified for this purpose. Samba 3.0 will
766 not fall back to using the 'add user script' in the absence of
767 an 'add machine script'
770 ######################################################################
771 Passdb Backends and Authentication
772 ##################################
774 There have been a few new changes that Samba administrators should be
775 aware of when moving to Samba 3.0.
777 1) encrypted passwords have been enabled by default in order to
778 inter-operate better with out-of-the-box Windows client
779 installations. This does mean that either (a) a samba account
780 must be created for each user, or (b) 'encrypt passwords = no'
781 must be explicitly defined in smb.conf.
783 2) Inclusion of new 'security = ads' option for integration
784 with an Active Directory domain using the native Windows
785 Kerberos 5 and LDAP protocols.
787 MIT kerberos 1.3.1 supports the ARCFOUR-HMAC-MD5 encryption
788 type which is neccessary for servers on which the
789 administrator password has not been changed, or kerberos-enabled
790 SMB connections to servers that require Kerberos SMB signing.
791 Besides this one difference, either MIT or Heimdal Kerberos
792 distributions are usable by Samba 3.0.
795 Samba 3.0 also includes the possibility of setting up chains
796 of authentication methods (auth methods) and account storage
797 backends (passdb backend). Please refer to the smb.conf(5)
798 man page for details. While both parameters assume sane default
799 values, it is likely that you will need to understand what the
800 values actually mean in order to ensure Samba operates correctly.
802 The recommended passdb backends at this time are
804 * smbpasswd - 2.2 compatible flat file format
805 * tdbsam - attribute rich database intended as an smbpasswd
806 replacement for stand alone servers
807 * ldapsam - attribute rich account storage and retrieval
808 backend utilizing an LDAP directory.
809 * ldapsam_compat - a 2.2 backward compatible LDAP account
812 Certain functions of the smbpasswd(8) tool have been split between the
813 new smbpasswd(8) utility, the net(8) tool, and the new pdbedit(8)
814 utility. See the respective man pages for details.
817 ######################################################################
821 This section outlines the new features affecting Samba / LDAP
827 A new object class (sambaSamAccount) has been introduced to replace
828 the old sambaAccount. This change aids us in the renaming of attributes
829 to prevent clashes with attributes from other vendors. There is a
830 conversion script (examples/LDAP/convertSambaAccount) to modify and LDIF
831 file to the new schema.
835 $ ldapsearch .... -b "ou=people,dc=..." > old.ldif
836 $ convertSambaAccount <DOM SID> old.ldif new.ldif
838 The <DOM SID> can be obtained by running 'net getlocalsid <DOMAINNAME>'
839 on the Samba PDC as root.
841 The old sambaAccount schema may still be used by specifying the
842 "ldapsam_compat" passdb backend. However, the sambaAccount and
843 associated attributes have been moved to the historical section of
844 the schema file and must be uncommented before use if needed.
845 The 2.2 object class declaration for a sambaAccount has not changed
846 in the 3.0 samba.schema file.
848 Other new object classes and their uses include:
850 * sambaDomain - domain information used to allocate rids
851 for users and groups as necessary. The attributes are added
852 in 'ldap suffix' directory entry automatically if
853 an idmap uid/gid range has been set and the 'ldapsam'
854 passdb backend has been selected.
856 * sambaGroupMapping - an object representing the
857 relationship between a posixGroup and a Windows
858 group/SID. These entries are stored in the 'ldap
859 group suffix' and managed by the 'net groupmap' command.
861 * sambaUnixIdPool - created in the 'ldap idmap suffix' entry
862 automatically and contains the next available 'idmap uid' and
865 * sambaIdmapEntry - object storing a mapping between a
866 SID and a UNIX uid/gid. These objects are created by the
867 idmap_ldap module as needed.
869 * sambaSidEntry - object representing a SID alone, as a Structural
870 class on which to build the sambaIdmapEntry.
873 New Suffix for Searching
874 ------------------------
876 The following new smb.conf parameters have been added to aid in directing
877 certain LDAP queries when 'passdb backend = ldapsam://...' has been
880 * ldap suffix - used to search for user and computer accounts
881 * ldap user suffix - used to store user accounts
882 * ldap machine suffix - used to store machine trust accounts
883 * ldap group suffix - location of posixGroup/sambaGroupMapping entries
884 * ldap idmap suffix - location of sambaIdmapEntry objects
886 If an 'ldap suffix' is defined, it will be appended to all of the
887 remaining sub-suffix parameters. In this case, the order of the suffix
888 listings in smb.conf is important. Always place the 'ldap suffix' first
891 Due to a limitation in Samba's smb.conf parsing, you should not surround
892 the DN's with quotation marks.
898 Samba 3.0 supports an ldap backend for the idmap subsystem. The
899 following options would inform Samba that the idmap table should be
900 stored on the directory server onterose in the "ou=idmap,dc=plainjoe,
905 idmap backend = ldap:ldap://onterose/
906 ldap idmap suffix = ou=idmap,dc=plainjoe,dc=org
907 idmap uid = 40000-50000
908 idmap gid = 40000-50000
910 This configuration allows winbind installations on multiple servers to
911 share a uid/gid number space, thus avoiding the interoperability problems
912 with NFS that were present in Samba 2.2.
916 ######################################################################
917 Trust Relationships and a Samba Domain
918 ######################################
920 Samba 3.0.0beta2 is able to utilize winbindd as the means of
921 allocating uids and gids to trusted users and groups. More
922 information regarding Samba's support for establishing trust
923 relationships can be found in the Samba-HOWTO-Collection included
924 in the docs/ directory of this release.
926 First create your Samba PDC and ensure that everything is
927 working correctly before moving on the trusts.
929 To establish Samba as the trusting domain (named SAMBA) from a Windows NT
930 4.0 domain named WINDOWS:
932 1) create the trust account for SAMBA in "User Manager for Domains"
933 2) connect the trust from the Samba domain using
934 'net rpc trustdom establish GLASS'
936 To create a trustlationship with SAMBA as the trusted domain:
938 1) create the initial trust account for GLASS using
939 'smbpasswd -a -i GLASS'. You may need to create a UNIX
940 account for GLASS$ prior to this step (depending on your
941 local configuration).
942 2) connect the trust from a WINDOWS DC using "User Manager
945 Now join winbindd on the Samba PDC to the SAMBA domain using
946 the normal steps for adding a Samba server to an NT4 domain:
947 (note that smbd & nmbd must be running at this point)
949 root# net rpc join -U root
950 Password: <enter root password from smbpasswd file here>
952 Start winbindd and test the join with 'wbinfo -t'.
954 Now test the trust relationship by connecting to the SAMBA DC
955 (e.g. POGO) as a user from the WINDOWS domain:
957 $ smbclient //pogo/netlogon -U Administrator -W WINDOWS
960 Now connect to the WINDOWS DC (e.g. CRYSTAL) as a Samba user:
962 $ smbclient //crystal/netlogon -U root -W WINDOWS
965 ######################################################################
969 Beginning with Samba3.0.0beta3, winbindd has been given new account
970 manage functionality equivalent to the 'add user script' family of
971 smb.conf parameters. The idmap design has also been changed to
972 centralize control of foreign SID lookups and matching to UNIX
976 Brief Description of Changes
977 ----------------------------
979 1) The sid_to_uid() family of functions (smbd/uid.c) have been
980 reverted to the 2.2.x design. This means that when resolving a
981 SID to a UID or similar mapping:
983 a) First consult winbindd
984 b) perform a local lookup only if winbindd fails to
985 return a successful answer
987 There are some variations to this, but these two rules generally
990 2) All idmap lookups have been moved into winbindd. This means that
991 a server must run winbindd (and support NSS) in order to achieve
992 any mappings of SID to dynamically allocated UNIX ids. This was
993 a conscious design choice.
995 3) New functions have been added to winbindd to emulate the 'add user
996 script' family of smbd functions without requiring that external
997 scripts be defined. This functionality is controlled by the 'winbind
998 enable local accounts' smb.conf parameter (enabled by default).
1000 However, this account management functionality is only supported
1001 in a local tdb (winbindd_idmap.tdb). If these new UNIX accounts
1002 must be shared among multiple Samba servers (such as a PDC and BDCs),
1003 it will be necessary to define your own 'add user script', et. al.
1004 programs that place the accounts/groups in some form of directory
1005 such as NIS or LDAP. This requirement was deemed beyond the scope
1006 of winbind's account management functions. Solutions for
1007 distributing UNIX system information have been deployed and tested
1008 for many years. We saw no need to reinvent the wheel.
1010 4) A member of a Samba controlled domain running winbindd is now able
1011 to map domain users directly onto existing UNIX accounts while still
1012 automatically creating accounts for trusted users and groups. This
1013 behavior is controlled by the 'winbind trusted domains only' smb.conf
1014 parameter (disabled by default to provide 2.2.x winbind behavior).
1016 5) Group mapping support is wrapped in the local_XX_to_XX() functions
1017 in smbd/uid.c. The reason that group mappings are not included
1018 in winbindd is because the purpose of Samba's group map is to
1019 match any Windows SID with an existing UNIX group. These UNIX
1020 groups can be created by winbindd (see next section), but the
1021 SID<->gid mapping is retreived by smbd, not winbindd.
1027 * security = server running winbindd to allocate accounts on demand
1029 * Samba PDC running winbindd to handle the automatic creation of UNIX
1030 identities for machine trust accounts
1032 * Automtically creating UNIX user and groups when migrating a Windows NT
1033 4.0 PDC to a Samba PDC. Winbindd must be running when executing
1034 'net rpc vampire' for this to work.
