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

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

432 ######################################################################
434 =======================================
435 The original 3.0.0 release notes follow
436 =======================================
442 1) Active Directory support. Samba 3.0 is now able to
443 join a ADS realm as a member server and authenticate
444 users using LDAP/Kerberos.
446 2) Unicode support. Samba will now negotiate UNICODE on the wire
447 and internally there is now a much better infrastructure for
448 multi-byte and UNICODE character sets.
450 3) New authentication system. The internal authentication system
451 has been almost completely rewritten. Most of the changes are
452 internal, but the new auth system is also very configurable.
454 4) New default filename mangling system.
456 5) A new "net" command has been added. It is somewhat similar to
457 the "net" command in windows. Eventually we plan to replace
458 numerous other utilities (such as smbpasswd) with subcommands
461 6) Samba now negotiates NT-style status32 codes on the wire. This
462 improves error handling a lot.
464 7) Better Windows 2000/XP/2003 printing support including publishing
465 printer attributes in active directory.
467 8) New loadable module support for passdb backends and character
470 9) New default dual-daemon winbindd support for better performance.
472 10) Support for migrating from a Windows NT 4.0 domain to a Samba
473 domain and maintaining user, group and domain SIDs.
475 11) Support for establishing trust relationships with Windows NT 4.0
478 12) Initial support for a distributed Winbind architecture using
479 an LDAP directory for storing SID to uid/gid mappings.
481 13) Major updates to the Samba documentation tree.
483 14) Full support for client and server SMB signing to ensure
484 compatibility with default Windows 2003 security settings.
486 15) Improvement of ACL mapping features based on code donated by
490 Plus lots of other improvements!
493 Additional Documentation
494 ------------------------
496 Please refer to Samba documentation tree (included in the docs/
497 subdirectory) for extensive explanations of installing, configuring
498 and maintaining Samba 3.0 servers and clients. It is advised to
499 begin with the Samba-HOWTO-Collection for overviews and specific
500 tasks (the current book is up to approximately 400 pages) and to
501 refer to the various man pages for information on individual options.
503 We are very glad to be able to include the second edition of
504 "Using Samba" by Jay Ts, Robert Eckstein, and David Collier-Brown
505 (O'Reilly & Associates) in this release. The book is available
506 on-line at http://samba.org/samba/docs/ and is included with
507 the Samba Web Administration Tool (SWAT). Thanks to the authors and
508 publisher for making "Using Samba" under the GNU Free Documentation
512 ######################################################################
513 Upgrading from a previous Samba 3.0 beta
514 ########################################
516 Beginning with Samba 3.0.0beta3, the RID allocation functions
517 have been moved into winbindd. Previously these were handled
518 by each passdb backend. This means that winbindd must be running
519 to automatically allocate RIDs for users and/or groups. Otherwise,
520 smbd will use the 2.2 algorithm for generating new RIDs.
522 If you are using 'passdb backend = tdbsam' with a previous Samba
523 3.0 beta release (or possibly alpha), it may be necessary to
524 move the RID_COUNTER entry from /usr/local/samba/private/passdb.tdb
525 to winbindd_idmap.tdb. To do this:
527 1) Ensure that winbindd_idmap.tdb exists (launch winbindd at least
529 2) build tdbtool by executing 'make tdbtool' in the source/tdb/
531 3) run: (note that 'tdb>' is the tool's prompt for input)
533 root# ./tdbtool /usr/local/samba/private/passdb.tdb
534 tdb> show RID_COUNTER
538 [000] 0A 52 00 00 .R.
540 tdb> move RID_COUNTER /usr/local/samba/var/locks/winbindd_idmap.tdb
544 If you are using 'passdb backend = ldapsam', it will be necessary to
545 store idmap entries in the LDAP directory as well (i.e. idmap backend
546 = ldap). Refer to the 'net idmap' command for more information on
547 migrating SID<->UNIX id mappings from one backend to another.
549 If the RID_COUNTER record does not exist, then these instructions are
550 unneccessary and the new RID_COUNTER record will be correctly generated

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

755 The following issues are known changes in behavior between Samba 2.2 and
756 Samba 3.0 that may affect certain installations of Samba.
758 1) When operating as a member of a Windows domain, Samba 2.2 would
759 map any users authenticated by the remote DC to the 'guest account'
760 if a uid could not be obtained via the getpwnam() call. Samba 3.0
761 rejects the connection as NT_STATUS_LOGON_FAILURE. There is no
762 current work around to re-establish the 2.2 behavior.
764 2) When adding machines to a Samba 2.2 controlled domain, the
765 'add user script' was used to create the UNIX identity of the
766 machine trust account. Samba 3.0 introduces a new 'add machine
767 script' that must be specified for this purpose. Samba 3.0 will
768 not fall back to using the 'add user script' in the absence of
769 an 'add machine script'
772 ######################################################################
773 Passdb Backends and Authentication
774 ##################################
776 There have been a few new changes that Samba administrators should be
777 aware of when moving to Samba 3.0.
779 1) encrypted passwords have been enabled by default in order to
780 inter-operate better with out-of-the-box Windows client
781 installations. This does mean that either (a) a samba account
782 must be created for each user, or (b) 'encrypt passwords = no'
783 must be explicitly defined in smb.conf.
785 2) Inclusion of new 'security = ads' option for integration
786 with an Active Directory domain using the native Windows
787 Kerberos 5 and LDAP protocols.
789 MIT kerberos 1.3.1 supports the ARCFOUR-HMAC-MD5 encryption
790 type which is neccessary for servers on which the
791 administrator password has not been changed, or kerberos-enabled
792 SMB connections to servers that require Kerberos SMB signing.
793 Besides this one difference, either MIT or Heimdal Kerberos
794 distributions are usable by Samba 3.0.
797 Samba 3.0 also includes the possibility of setting up chains
798 of authentication methods (auth methods) and account storage
799 backends (passdb backend). Please refer to the smb.conf(5)
800 man page for details. While both parameters assume sane default
801 values, it is likely that you will need to understand what the
802 values actually mean in order to ensure Samba operates correctly.
804 The recommended passdb backends at this time are
806 * smbpasswd - 2.2 compatible flat file format
807 * tdbsam - attribute rich database intended as an smbpasswd
808 replacement for stand alone servers
809 * ldapsam - attribute rich account storage and retrieval
810 backend utilizing an LDAP directory.
811 * ldapsam_compat - a 2.2 backward compatible LDAP account
814 Certain functions of the smbpasswd(8) tool have been split between the
815 new smbpasswd(8) utility, the net(8) tool, and the new pdbedit(8)
816 utility. See the respective man pages for details.
819 ######################################################################
823 This section outlines the new features affecting Samba / LDAP
829 A new object class (sambaSamAccount) has been introduced to replace
830 the old sambaAccount. This change aids us in the renaming of attributes
831 to prevent clashes with attributes from other vendors. There is a
832 conversion script (examples/LDAP/convertSambaAccount) to modify and LDIF
833 file to the new schema.
837 $ ldapsearch .... -b "ou=people,dc=..." > old.ldif
838 $ convertSambaAccount <DOM SID> old.ldif new.ldif
840 The <DOM SID> can be obtained by running 'net getlocalsid <DOMAINNAME>'
841 on the Samba PDC as root.
843 The old sambaAccount schema may still be used by specifying the
844 "ldapsam_compat" passdb backend. However, the sambaAccount and
845 associated attributes have been moved to the historical section of
846 the schema file and must be uncommented before use if needed.
847 The 2.2 object class declaration for a sambaAccount has not changed
848 in the 3.0 samba.schema file.
850 Other new object classes and their uses include:
852 * sambaDomain - domain information used to allocate rids
853 for users and groups as necessary. The attributes are added
854 in 'ldap suffix' directory entry automatically if
855 an idmap uid/gid range has been set and the 'ldapsam'
856 passdb backend has been selected.
858 * sambaGroupMapping - an object representing the
859 relationship between a posixGroup and a Windows
860 group/SID. These entries are stored in the 'ldap
861 group suffix' and managed by the 'net groupmap' command.
863 * sambaUnixIdPool - created in the 'ldap idmap suffix' entry
864 automatically and contains the next available 'idmap uid' and
867 * sambaIdmapEntry - object storing a mapping between a
868 SID and a UNIX uid/gid. These objects are created by the
869 idmap_ldap module as needed.
871 * sambaSidEntry - object representing a SID alone, as a Structural
872 class on which to build the sambaIdmapEntry.
875 New Suffix for Searching
876 ------------------------
878 The following new smb.conf parameters have been added to aid in directing
879 certain LDAP queries when 'passdb backend = ldapsam://...' has been
882 * ldap suffix - used to search for user and computer accounts
883 * ldap user suffix - used to store user accounts
884 * ldap machine suffix - used to store machine trust accounts
885 * ldap group suffix - location of posixGroup/sambaGroupMapping entries
886 * ldap idmap suffix - location of sambaIdmapEntry objects
888 If an 'ldap suffix' is defined, it will be appended to all of the
889 remaining sub-suffix parameters. In this case, the order of the suffix
890 listings in smb.conf is important. Always place the 'ldap suffix' first
893 Due to a limitation in Samba's smb.conf parsing, you should not surround
894 the DN's with quotation marks.
900 Samba 3.0 supports an ldap backend for the idmap subsystem. The
901 following options would inform Samba that the idmap table should be
902 stored on the directory server onterose in the "ou=idmap,dc=plainjoe,
907 idmap backend = ldap:ldap://onterose/
908 ldap idmap suffix = ou=idmap,dc=plainjoe,dc=org
909 idmap uid = 40000-50000
910 idmap gid = 40000-50000
912 This configuration allows winbind installations on multiple servers to
913 share a uid/gid number space, thus avoiding the interoperability problems
914 with NFS that were present in Samba 2.2.
918 ######################################################################
919 Trust Relationships and a Samba Domain
920 ######################################
922 Samba 3.0.0beta2 is able to utilize winbindd as the means of
923 allocating uids and gids to trusted users and groups. More
924 information regarding Samba's support for establishing trust
925 relationships can be found in the Samba-HOWTO-Collection included
926 in the docs/ directory of this release.
928 First create your Samba PDC and ensure that everything is
929 working correctly before moving on the trusts.
931 To establish Samba as the trusting domain (named SAMBA) from a Windows NT
932 4.0 domain named WINDOWS:
934 1) create the trust account for SAMBA in "User Manager for Domains"
935 2) connect the trust from the Samba domain using
936 'net rpc trustdom establish GLASS'
938 To create a trustlationship with SAMBA as the trusted domain:
940 1) create the initial trust account for GLASS using
941 'smbpasswd -a -i GLASS'. You may need to create a UNIX
942 account for GLASS$ prior to this step (depending on your
943 local configuration).
944 2) connect the trust from a WINDOWS DC using "User Manager
947 Now join winbindd on the Samba PDC to the SAMBA domain using
948 the normal steps for adding a Samba server to an NT4 domain:
949 (note that smbd & nmbd must be running at this point)
951 root# net rpc join -U root
952 Password: <enter root password from smbpasswd file here>
954 Start winbindd and test the join with 'wbinfo -t'.
956 Now test the trust relationship by connecting to the SAMBA DC
957 (e.g. POGO) as a user from the WINDOWS domain:
959 $ smbclient //pogo/netlogon -U Administrator -W WINDOWS
962 Now connect to the WINDOWS DC (e.g. CRYSTAL) as a Samba user:
964 $ smbclient //crystal/netlogon -U root -W WINDOWS
967 ######################################################################
971 Beginning with Samba3.0.0beta3, winbindd has been given new account
972 manage functionality equivalent to the 'add user script' family of
973 smb.conf parameters. The idmap design has also been changed to
974 centralize control of foreign SID lookups and matching to UNIX
978 Brief Description of Changes
979 ----------------------------
981 1) The sid_to_uid() family of functions (smbd/uid.c) have been
982 reverted to the 2.2.x design. This means that when resolving a
983 SID to a UID or similar mapping:
985 a) First consult winbindd
986 b) perform a local lookup only if winbindd fails to
987 return a successful answer
989 There are some variations to this, but these two rules generally
992 2) All idmap lookups have been moved into winbindd. This means that
993 a server must run winbindd (and support NSS) in order to achieve
994 any mappings of SID to dynamically allocated UNIX ids. This was
995 a conscious design choice.
997 3) New functions have been added to winbindd to emulate the 'add user
998 script' family of smbd functions without requiring that external
999 scripts be defined. This functionality is controlled by the 'winbind
1000 enable local accounts' smb.conf parameter (enabled by default).
1002 However, this account management functionality is only supported
1003 in a local tdb (winbindd_idmap.tdb). If these new UNIX accounts
1004 must be shared among multiple Samba servers (such as a PDC and BDCs),
1005 it will be necessary to define your own 'add user script', et. al.
1006 programs that place the accounts/groups in some form of directory
1007 such as NIS or LDAP. This requirement was deemed beyond the scope
1008 of winbind's account management functions. Solutions for
1009 distributing UNIX system information have been deployed and tested
1010 for many years. We saw no need to reinvent the wheel.
1012 4) A member of a Samba controlled domain running winbindd is now able
1013 to map domain users directly onto existing UNIX accounts while still
1014 automatically creating accounts for trusted users and groups. This
1015 behavior is controlled by the 'winbind trusted domains only' smb.conf
1016 parameter (disabled by default to provide 2.2.x winbind behavior).
1018 5) Group mapping support is wrapped in the local_XX_to_XX() functions
1019 in smbd/uid.c. The reason that group mappings are not included
1020 in winbindd is because the purpose of Samba's group map is to
1021 match any Windows SID with an existing UNIX group. These UNIX
1022 groups can be created by winbindd (see next section), but the
1023 SID<->gid mapping is retreived by smbd, not winbindd.
1029 * security = server running winbindd to allocate accounts on demand
1031 * Samba PDC running winbindd to handle the automatic creation of UNIX
1032 identities for machine trust accounts
1034 * Automtically creating UNIX user and groups when migrating a Windows NT
1035 4.0 PDC to a Samba PDC. Winbindd must be running when executing
1036 'net rpc vampire' for this to work.
