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
11 for wider testings. See the "Changes" section for details on

333 winbindd pipe protocol.
334 o Adds a variant of the winbindd_getgroups() call called
335 winbindd_getusersids() that provides direct SID->SIDs listing of a
336 users supplementary groups. This is enough to allow non-Samba
337 applications to do ACL checking.

424 ######################################################################
426 =======================================
427 The original 3.0.0 release notes follow
428 =======================================
434 1) Active Directory support. Samba 3.0 is now able to
435 join a ADS realm as a member server and authenticate
436 users using LDAP/Kerberos.
438 2) Unicode support. Samba will now negotiate UNICODE on the wire
439 and internally there is now a much better infrastructure for
440 multi-byte and UNICODE character sets.
442 3) New authentication system. The internal authentication system
443 has been almost completely rewritten. Most of the changes are
444 internal, but the new auth system is also very configurable.
446 4) New default filename mangling system.
448 5) A new "net" command has been added. It is somewhat similar to
449 the "net" command in windows. Eventually we plan to replace
450 numerous other utilities (such as smbpasswd) with subcommands
453 6) Samba now negotiates NT-style status32 codes on the wire. This
454 improves error handling a lot.
456 7) Better Windows 2000/XP/2003 printing support including publishing
457 printer attributes in active directory.
459 8) New loadable module support for passdb backends and character
462 9) New default dual-daemon winbindd support for better performance.
464 10) Support for migrating from a Windows NT 4.0 domain to a Samba
465 domain and maintaining user, group and domain SIDs.
467 11) Support for establishing trust relationships with Windows NT 4.0
470 12) Initial support for a distributed Winbind architecture using
471 an LDAP directory for storing SID to uid/gid mappings.
473 13) Major updates to the Samba documentation tree.
475 14) Full support for client and server SMB signing to ensure
476 compatibility with default Windows 2003 security settings.
478 15) Improvement of ACL mapping features based on code donated by
482 Plus lots of other improvements!
485 Additional Documentation
486 ------------------------
488 Please refer to Samba documentation tree (included in the docs/
489 subdirectory) for extensive explanations of installing, configuring
490 and maintaining Samba 3.0 servers and clients. It is advised to
491 begin with the Samba-HOWTO-Collection for overviews and specific
492 tasks (the current book is up to approximately 400 pages) and to
493 refer to the various man pages for information on individual options.
495 We are very glad to be able to include the second edition of
496 "Using Samba" by Jay Ts, Robert Eckstein, and David Collier-Brown
497 (O'Reilly & Associates) in this release. The book is available
498 on-line at http://samba.org/samba/docs/ and is included with
499 the Samba Web Administration Tool (SWAT). Thanks to the authors and
500 publisher for making "Using Samba" under the GNU Free Documentation
504 ######################################################################
505 Upgrading from a previous Samba 3.0 beta
506 ########################################
508 Beginning with Samba 3.0.0beta3, the RID allocation functions
509 have been moved into winbindd. Previously these were handled
510 by each passdb backend. This means that winbindd must be running
511 to automatically allocate RIDs for users and/or groups. Otherwise,
512 smbd will use the 2.2 algorithm for generating new RIDs.
514 If you are using 'passdb backend = tdbsam' with a previous Samba
515 3.0 beta release (or possibly alpha), it may be necessary to
516 move the RID_COUNTER entry from /usr/local/samba/private/passdb.tdb
517 to winbindd_idmap.tdb. To do this:
519 1) Ensure that winbindd_idmap.tdb exists (launch winbindd at least
521 2) build tdbtool by executing 'make tdbtool' in the source/tdb/
523 3) run: (note that 'tdb>' is the tool's prompt for input)
525 root# ./tdbtool /usr/local/samba/private/passdb.tdb
526 tdb> show RID_COUNTER
530 [000] 0A 52 00 00 .R.
532 tdb> move RID_COUNTER /usr/local/samba/var/locks/winbindd_idmap.tdb
536 If you are using 'passdb backend = ldapsam', it will be necessary to
537 store idmap entries in the LDAP directory as well (i.e. idmap backend
538 = ldap). Refer to the 'net idmap' command for more information on
539 migrating SID<->UNIX id mappings from one backend to another.
541 If the RID_COUNTER record does not exist, then these instructions are
542 unneccessary and the new RID_COUNTER record will be correctly generated

718 This section contains brief descriptions of any new databases
719 introduced in Samba 3.0. Please remember to backup your existing
720 ${lock directory}/*tdb before upgrading to Samba 3.0. Samba will
721 upgrade databases as they are opened (if necessary), but downgrading
722 from 3.0 to 2.2 is an unsupported path.

747 The following issues are known changes in behavior between Samba 2.2 and
748 Samba 3.0 that may affect certain installations of Samba.
750 1) When operating as a member of a Windows domain, Samba 2.2 would
751 map any users authenticated by the remote DC to the 'guest account'
752 if a uid could not be obtained via the getpwnam() call. Samba 3.0
753 rejects the connection as NT_STATUS_LOGON_FAILURE. There is no
754 current work around to re-establish the 2.2 behavior.
756 2) When adding machines to a Samba 2.2 controlled domain, the
757 'add user script' was used to create the UNIX identity of the
758 machine trust account. Samba 3.0 introduces a new 'add machine
759 script' that must be specified for this purpose. Samba 3.0 will
760 not fall back to using the 'add user script' in the absence of
761 an 'add machine script'
764 ######################################################################
765 Passdb Backends and Authentication
766 ##################################
768 There have been a few new changes that Samba administrators should be
769 aware of when moving to Samba 3.0.
771 1) encrypted passwords have been enabled by default in order to
772 inter-operate better with out-of-the-box Windows client
773 installations. This does mean that either (a) a samba account
774 must be created for each user, or (b) 'encrypt passwords = no'
775 must be explicitly defined in smb.conf.
777 2) Inclusion of new 'security = ads' option for integration
778 with an Active Directory domain using the native Windows
779 Kerberos 5 and LDAP protocols.
781 MIT kerberos 1.3.1 supports the ARCFOUR-HMAC-MD5 encryption
782 type which is neccessary for servers on which the
783 administrator password has not been changed, or kerberos-enabled
784 SMB connections to servers that require Kerberos SMB signing.
785 Besides this one difference, either MIT or Heimdal Kerberos
786 distributions are usable by Samba 3.0.
789 Samba 3.0 also includes the possibility of setting up chains
790 of authentication methods (auth methods) and account storage
791 backends (passdb backend). Please refer to the smb.conf(5)
792 man page for details. While both parameters assume sane default
793 values, it is likely that you will need to understand what the
794 values actually mean in order to ensure Samba operates correctly.
796 The recommended passdb backends at this time are
798 * smbpasswd - 2.2 compatible flat file format
799 * tdbsam - attribute rich database intended as an smbpasswd
800 replacement for stand alone servers
801 * ldapsam - attribute rich account storage and retrieval
802 backend utilizing an LDAP directory.
803 * ldapsam_compat - a 2.2 backward compatible LDAP account
806 Certain functions of the smbpasswd(8) tool have been split between the
807 new smbpasswd(8) utility, the net(8) tool, and the new pdbedit(8)
808 utility. See the respective man pages for details.
811 ######################################################################
815 This section outlines the new features affecting Samba / LDAP
821 A new object class (sambaSamAccount) has been introduced to replace
822 the old sambaAccount. This change aids us in the renaming of attributes
823 to prevent clashes with attributes from other vendors. There is a
824 conversion script (examples/LDAP/convertSambaAccount) to modify and LDIF
825 file to the new schema.
829 $ ldapsearch .... -b "ou=people,dc=..." > old.ldif
830 $ convertSambaAccount <DOM SID> old.ldif new.ldif
832 The <DOM SID> can be obtained by running 'net getlocalsid <DOMAINNAME>'
833 on the Samba PDC as root.
835 The old sambaAccount schema may still be used by specifying the
836 "ldapsam_compat" passdb backend. However, the sambaAccount and
837 associated attributes have been moved to the historical section of
838 the schema file and must be uncommented before use if needed.
839 The 2.2 object class declaration for a sambaAccount has not changed
840 in the 3.0 samba.schema file.
842 Other new object classes and their uses include:
844 * sambaDomain - domain information used to allocate rids
845 for users and groups as necessary. The attributes are added
846 in 'ldap suffix' directory entry automatically if
847 an idmap uid/gid range has been set and the 'ldapsam'
848 passdb backend has been selected.
850 * sambaGroupMapping - an object representing the
851 relationship between a posixGroup and a Windows
852 group/SID. These entries are stored in the 'ldap
853 group suffix' and managed by the 'net groupmap' command.
855 * sambaUnixIdPool - created in the 'ldap idmap suffix' entry
856 automatically and contains the next available 'idmap uid' and
859 * sambaIdmapEntry - object storing a mapping between a
860 SID and a UNIX uid/gid. These objects are created by the
861 idmap_ldap module as needed.
863 * sambaSidEntry - object representing a SID alone, as a Structural
864 class on which to build the sambaIdmapEntry.
867 New Suffix for Searching
868 ------------------------
870 The following new smb.conf parameters have been added to aid in directing
871 certain LDAP queries when 'passdb backend = ldapsam://...' has been
874 * ldap suffix - used to search for user and computer accounts
875 * ldap user suffix - used to store user accounts
876 * ldap machine suffix - used to store machine trust accounts
877 * ldap group suffix - location of posixGroup/sambaGroupMapping entries
878 * ldap idmap suffix - location of sambaIdmapEntry objects
880 If an 'ldap suffix' is defined, it will be appended to all of the
881 remaining sub-suffix parameters. In this case, the order of the suffix
882 listings in smb.conf is important. Always place the 'ldap suffix' first
885 Due to a limitation in Samba's smb.conf parsing, you should not surround
886 the DN's with quotation marks.
892 Samba 3.0 supports an ldap backend for the idmap subsystem. The
893 following options would inform Samba that the idmap table should be
894 stored on the directory server onterose in the "ou=idmap,dc=plainjoe,
899 idmap backend = ldap:ldap://onterose/
900 ldap idmap suffix = ou=idmap,dc=plainjoe,dc=org
901 idmap uid = 40000-50000
902 idmap gid = 40000-50000
904 This configuration allows winbind installations on multiple servers to
905 share a uid/gid number space, thus avoiding the interoperability problems
906 with NFS that were present in Samba 2.2.
910 ######################################################################
911 Trust Relationships and a Samba Domain
912 ######################################
914 Samba 3.0.0beta2 is able to utilize winbindd as the means of
915 allocating uids and gids to trusted users and groups. More
916 information regarding Samba's support for establishing trust
917 relationships can be found in the Samba-HOWTO-Collection included
918 in the docs/ directory of this release.
920 First create your Samba PDC and ensure that everything is
921 working correctly before moving on the trusts.
923 To establish Samba as the trusting domain (named SAMBA) from a Windows NT
924 4.0 domain named WINDOWS:
926 1) create the trust account for SAMBA in "User Manager for Domains"
927 2) connect the trust from the Samba domain using
928 'net rpc trustdom establish GLASS'
930 To create a trustlationship with SAMBA as the trusted domain:
932 1) create the initial trust account for GLASS using
933 'smbpasswd -a -i GLASS'. You may need to create a UNIX
934 account for GLASS$ prior to this step (depending on your
935 local configuration).
936 2) connect the trust from a WINDOWS DC using "User Manager
939 Now join winbindd on the Samba PDC to the SAMBA domain using
940 the normal steps for adding a Samba server to an NT4 domain:
941 (note that smbd & nmbd must be running at this point)
943 root# net rpc join -U root
944 Password: <enter root password from smbpasswd file here>
946 Start winbindd and test the join with 'wbinfo -t'.
948 Now test the trust relationship by connecting to the SAMBA DC
949 (e.g. POGO) as a user from the WINDOWS domain:
951 $ smbclient //pogo/netlogon -U Administrator -W WINDOWS
954 Now connect to the WINDOWS DC (e.g. CRYSTAL) as a Samba user:
956 $ smbclient //crystal/netlogon -U root -W WINDOWS
959 ######################################################################
963 Beginning with Samba3.0.0beta3, winbindd has been given new account
964 manage functionality equivalent to the 'add user script' family of
965 smb.conf parameters. The idmap design has also been changed to
966 centralize control of foreign SID lookups and matching to UNIX
970 Brief Description of Changes
971 ----------------------------
973 1) The sid_to_uid() family of functions (smbd/uid.c) have been
974 reverted to the 2.2.x design. This means that when resolving a
975 SID to a UID or similar mapping:
977 a) First consult winbindd
978 b) perform a local lookup only if winbindd fails to
979 return a successful answer
981 There are some variations to this, but these two rules generally
984 2) All idmap lookups have been moved into winbindd. This means that
985 a server must run winbindd (and support NSS) in order to achieve
986 any mappings of SID to dynamically allocated UNIX ids. This was
987 a conscious design choice.
989 3) New functions have been added to winbindd to emulate the 'add user
990 script' family of smbd functions without requiring that external
991 scripts be defined. This functionality is controlled by the 'winbind
992 enable local accounts' smb.conf parameter (enabled by default).
994 However, this account management functionality is only supported
995 in a local tdb (winbindd_idmap.tdb). If these new UNIX accounts
996 must be shared among multiple Samba servers (such as a PDC and BDCs),
997 it will be necessary to define your own 'add user script', et. al.
998 programs that place the accounts/groups in some form of directory
999 such as NIS or LDAP. This requirement was deemed beyond the scope
1000 of winbind's account management functions. Solutions for
1001 distributing UNIX system information have been deployed and tested
1002 for many years. We saw no need to reinvent the wheel.
1004 4) A member of a Samba controlled domain running winbindd is now able
1005 to map domain users directly onto existing UNIX accounts while still
1006 automatically creating accounts for trusted users and groups. This
1007 behavior is controlled by the 'winbind trusted domains only' smb.conf
1008 parameter (disabled by default to provide 2.2.x winbind behavior).
1010 5) Group mapping support is wrapped in the local_XX_to_XX() functions
1011 in smbd/uid.c. The reason that group mappings are not included
1012 in winbindd is because the purpose of Samba's group map is to
1013 match any Windows SID with an existing UNIX group. These UNIX
1014 groups can be created by winbindd (see next section), but the
1015 SID<->gid mapping is retreived by smbd, not winbindd.
1021 * security = server running winbindd to allocate accounts on demand
1023 * Samba PDC running winbindd to handle the automatic creation of UNIX
1024 identities for machine trust accounts
1026 * Automtically creating UNIX user and groups when migrating a Windows NT
1027 4.0 PDC to a Samba PDC. Winbindd must be running when executing
1028 'net rpc vampire' for this to work.
