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

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

412 to "smbprn.00000033 Test Page" so that we can get the smb
413 jobid back. This allow users to delete jobs with cups printing
414 backend (partial work on bug 770).
415 o Fix build of winbindd with static pdb modules.

478 ######################################################################
480 =======================================
481 The original 3.0.0 release notes follow
482 =======================================
488 1) Active Directory support. Samba 3.0 is now able to
489 join a ADS realm as a member server and authenticate
490 users using LDAP/Kerberos.
492 2) Unicode support. Samba will now negotiate UNICODE on the wire
493 and internally there is now a much better infrastructure for
494 multi-byte and UNICODE character sets.
496 3) New authentication system. The internal authentication system
497 has been almost completely rewritten. Most of the changes are
498 internal, but the new auth system is also very configurable.
500 4) New default filename mangling system.
502 5) A new "net" command has been added. It is somewhat similar to
503 the "net" command in windows. Eventually we plan to replace
504 numerous other utilities (such as smbpasswd) with subcommands
507 6) Samba now negotiates NT-style status32 codes on the wire. This
508 improves error handling a lot.
510 7) Better Windows 2000/XP/2003 printing support including publishing
511 printer attributes in active directory.
513 8) New loadable module support for passdb backends and character
516 9) New default dual-daemon winbindd support for better performance.
518 10) Support for migrating from a Windows NT 4.0 domain to a Samba
519 domain and maintaining user, group and domain SIDs.
521 11) Support for establishing trust relationships with Windows NT 4.0
524 12) Initial support for a distributed Winbind architecture using
525 an LDAP directory for storing SID to uid/gid mappings.
527 13) Major updates to the Samba documentation tree.
529 14) Full support for client and server SMB signing to ensure
530 compatibility with default Windows 2003 security settings.
532 15) Improvement of ACL mapping features based on code donated by
536 Plus lots of other improvements!
539 Additional Documentation
540 ------------------------
542 Please refer to Samba documentation tree (included in the docs/
543 subdirectory) for extensive explanations of installing, configuring
544 and maintaining Samba 3.0 servers and clients. It is advised to
545 begin with the Samba-HOWTO-Collection for overviews and specific
546 tasks (the current book is up to approximately 400 pages) and to
547 refer to the various man pages for information on individual options.
549 We are very glad to be able to include the second edition of
550 "Using Samba" by Jay Ts, Robert Eckstein, and David Collier-Brown
551 (O'Reilly & Associates) in this release. The book is available
552 on-line at http://samba.org/samba/docs/ and is included with
553 the Samba Web Administration Tool (SWAT). Thanks to the authors and
554 publisher for making "Using Samba" under the GNU Free Documentation
558 ######################################################################
559 Upgrading from a previous Samba 3.0 beta
560 ########################################
562 Beginning with Samba 3.0.0beta3, the RID allocation functions
563 have been moved into winbindd. Previously these were handled
564 by each passdb backend. This means that winbindd must be running
565 to automatically allocate RIDs for users and/or groups. Otherwise,
566 smbd will use the 2.2 algorithm for generating new RIDs.
568 If you are using 'passdb backend = tdbsam' with a previous Samba
569 3.0 beta release (or possibly alpha), it may be necessary to
570 move the RID_COUNTER entry from /usr/local/samba/private/passdb.tdb
571 to winbindd_idmap.tdb. To do this:
573 1) Ensure that winbindd_idmap.tdb exists (launch winbindd at least
575 2) build tdbtool by executing 'make tdbtool' in the source/tdb/
577 3) run: (note that 'tdb>' is the tool's prompt for input)
579 root# ./tdbtool /usr/local/samba/private/passdb.tdb
580 tdb> show RID_COUNTER
584 [000] 0A 52 00 00 .R.
586 tdb> move RID_COUNTER /usr/local/samba/var/locks/winbindd_idmap.tdb
590 If you are using 'passdb backend = ldapsam', it will be necessary to
591 store idmap entries in the LDAP directory as well (i.e. idmap backend
592 = ldap). Refer to the 'net idmap' command for more information on
593 migrating SID<->UNIX id mappings from one backend to another.
595 If the RID_COUNTER record does not exist, then these instructions are
596 unneccessary and the new RID_COUNTER record will be correctly generated

602 Upgrading from Samba 2.2
603 ########################
605 This section is provided to help administrators understand the details
606 involved with upgrading a Samba 2.2 server to Samba 3.0.
612 Many of the options to the GNU autoconf script have been modified
613 in the 3.0 release. The most noticeable are:
615 * removal of --with-tdbsam (is now included by default; see section
616 on passdb backends and authentication for more details)

620 backend and authentication section for more details
622 * inclusion of non-standard passdb modules may be enabled using
623 --with-expsam. This includes an XML backend and a mysql backend.
625 * removal of --with-msdfs (is now enabled by default)
627 * removal of --with-ssl (no longer supported)
629 * --with-utmp now defaults to 'yes' on supported systems

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

790 printing/*.tdb Cached output from 'lpq no
791 command' created on a per print
793 registry Read-only samba registry skeleton no
794 that provides support for exporting
795 various db tables via the winreg RPCs
801 The following issues are known changes in behavior between Samba 2.2 and
802 Samba 3.0 that may affect certain installations of Samba.
804 1) When operating as a member of a Windows domain, Samba 2.2 would
805 map any users authenticated by the remote DC to the 'guest account'
806 if a uid could not be obtained via the getpwnam() call. Samba 3.0
807 rejects the connection as NT_STATUS_LOGON_FAILURE. There is no
808 current work around to re-establish the 2.2 behavior.
810 2) When adding machines to a Samba 2.2 controlled domain, the
811 'add user script' was used to create the UNIX identity of the
812 machine trust account. Samba 3.0 introduces a new 'add machine
813 script' that must be specified for this purpose. Samba 3.0 will
814 not fall back to using the 'add user script' in the absence of
815 an 'add machine script'
818 ######################################################################
819 Passdb Backends and Authentication
820 ##################################
822 There have been a few new changes that Samba administrators should be
823 aware of when moving to Samba 3.0.
825 1) encrypted passwords have been enabled by default in order to
826 inter-operate better with out-of-the-box Windows client
827 installations. This does mean that either (a) a samba account
828 must be created for each user, or (b) 'encrypt passwords = no'
829 must be explicitly defined in smb.conf.
831 2) Inclusion of new 'security = ads' option for integration
832 with an Active Directory domain using the native Windows
833 Kerberos 5 and LDAP protocols.
835 MIT kerberos 1.3.1 supports the ARCFOUR-HMAC-MD5 encryption
836 type which is neccessary for servers on which the
837 administrator password has not been changed, or kerberos-enabled
838 SMB connections to servers that require Kerberos SMB signing.
839 Besides this one difference, either MIT or Heimdal Kerberos
840 distributions are usable by Samba 3.0.
843 Samba 3.0 also includes the possibility of setting up chains
844 of authentication methods (auth methods) and account storage
845 backends (passdb backend). Please refer to the smb.conf(5)
846 man page for details. While both parameters assume sane default
847 values, it is likely that you will need to understand what the
848 values actually mean in order to ensure Samba operates correctly.
850 The recommended passdb backends at this time are
852 * smbpasswd - 2.2 compatible flat file format
853 * tdbsam - attribute rich database intended as an smbpasswd
854 replacement for stand alone servers
855 * ldapsam - attribute rich account storage and retrieval
856 backend utilizing an LDAP directory.
857 * ldapsam_compat - a 2.2 backward compatible LDAP account
860 Certain functions of the smbpasswd(8) tool have been split between the
861 new smbpasswd(8) utility, the net(8) tool, and the new pdbedit(8)
862 utility. See the respective man pages for details.
865 ######################################################################
869 This section outlines the new features affecting Samba / LDAP
875 A new object class (sambaSamAccount) has been introduced to replace
876 the old sambaAccount. This change aids us in the renaming of attributes
877 to prevent clashes with attributes from other vendors. There is a
878 conversion script (examples/LDAP/convertSambaAccount) to modify and LDIF
879 file to the new schema.
883 $ ldapsearch .... -b "ou=people,dc=..." > old.ldif
884 $ convertSambaAccount <DOM SID> old.ldif new.ldif
886 The <DOM SID> can be obtained by running 'net getlocalsid <DOMAINNAME>'
887 on the Samba PDC as root.
889 The old sambaAccount schema may still be used by specifying the
890 "ldapsam_compat" passdb backend. However, the sambaAccount and
891 associated attributes have been moved to the historical section of
892 the schema file and must be uncommented before use if needed.
893 The 2.2 object class declaration for a sambaAccount has not changed
894 in the 3.0 samba.schema file.
896 Other new object classes and their uses include:
898 * sambaDomain - domain information used to allocate rids
899 for users and groups as necessary. The attributes are added
900 in 'ldap suffix' directory entry automatically if
901 an idmap uid/gid range has been set and the 'ldapsam'
902 passdb backend has been selected.
904 * sambaGroupMapping - an object representing the
905 relationship between a posixGroup and a Windows
906 group/SID. These entries are stored in the 'ldap
907 group suffix' and managed by the 'net groupmap' command.
909 * sambaUnixIdPool - created in the 'ldap idmap suffix' entry
910 automatically and contains the next available 'idmap uid' and
913 * sambaIdmapEntry - object storing a mapping between a
914 SID and a UNIX uid/gid. These objects are created by the
915 idmap_ldap module as needed.
917 * sambaSidEntry - object representing a SID alone, as a Structural
918 class on which to build the sambaIdmapEntry.
921 New Suffix for Searching
922 ------------------------
924 The following new smb.conf parameters have been added to aid in directing
925 certain LDAP queries when 'passdb backend = ldapsam://...' has been
928 * ldap suffix - used to search for user and computer accounts
929 * ldap user suffix - used to store user accounts
930 * ldap machine suffix - used to store machine trust accounts
931 * ldap group suffix - location of posixGroup/sambaGroupMapping entries
932 * ldap idmap suffix - location of sambaIdmapEntry objects
934 If an 'ldap suffix' is defined, it will be appended to all of the
935 remaining sub-suffix parameters. In this case, the order of the suffix
936 listings in smb.conf is important. Always place the 'ldap suffix' first
939 Due to a limitation in Samba's smb.conf parsing, you should not surround
940 the DN's with quotation marks.
946 Samba 3.0 supports an ldap backend for the idmap subsystem. The
947 following options would inform Samba that the idmap table should be
948 stored on the directory server onterose in the "ou=idmap,dc=plainjoe,
953 idmap backend = ldap:ldap://onterose/
954 ldap idmap suffix = ou=idmap,dc=plainjoe,dc=org
955 idmap uid = 40000-50000
956 idmap gid = 40000-50000
958 This configuration allows winbind installations on multiple servers to
959 share a uid/gid number space, thus avoiding the interoperability problems
960 with NFS that were present in Samba 2.2.
964 ######################################################################
965 Trust Relationships and a Samba Domain
966 ######################################
968 Samba 3.0.0beta2 is able to utilize winbindd as the means of
969 allocating uids and gids to trusted users and groups. More
970 information regarding Samba's support for establishing trust
971 relationships can be found in the Samba-HOWTO-Collection included
972 in the docs/ directory of this release.
974 First create your Samba PDC and ensure that everything is
975 working correctly before moving on the trusts.
977 To establish Samba as the trusting domain (named SAMBA) from a Windows NT
978 4.0 domain named WINDOWS:
980 1) create the trust account for SAMBA in "User Manager for Domains"
981 2) connect the trust from the Samba domain using
982 'net rpc trustdom establish GLASS'
984 To create a trustlationship with SAMBA as the trusted domain:
986 1) create the initial trust account for GLASS using
987 'smbpasswd -a -i GLASS'. You may need to create a UNIX
988 account for GLASS$ prior to this step (depending on your
989 local configuration).
990 2) connect the trust from a WINDOWS DC using "User Manager
993 Now join winbindd on the Samba PDC to the SAMBA domain using
994 the normal steps for adding a Samba server to an NT4 domain:
995 (note that smbd & nmbd must be running at this point)
997 root# net rpc join -U root
998 Password: <enter root password from smbpasswd file here>
1000 Start winbindd and test the join with 'wbinfo -t'.
1002 Now test the trust relationship by connecting to the SAMBA DC
1003 (e.g. POGO) as a user from the WINDOWS domain:
1005 $ smbclient //pogo/netlogon -U Administrator -W WINDOWS
1008 Now connect to the WINDOWS DC (e.g. CRYSTAL) as a Samba user:
1010 $ smbclient //crystal/netlogon -U root -W WINDOWS
1013 ######################################################################
1017 Beginning with Samba3.0.0beta3, winbindd has been given new account
1018 manage functionality equivalent to the 'add user script' family of
1019 smb.conf parameters. The idmap design has also been changed to
1020 centralize control of foreign SID lookups and matching to UNIX
1024 Brief Description of Changes
1025 ----------------------------
1027 1) The sid_to_uid() family of functions (smbd/uid.c) have been
1028 reverted to the 2.2.x design. This means that when resolving a
1029 SID to a UID or similar mapping:
1031 a) First consult winbindd
1032 b) perform a local lookup only if winbindd fails to
1033 return a successful answer
1035 There are some variations to this, but these two rules generally
1038 2) All idmap lookups have been moved into winbindd. This means that
1039 a server must run winbindd (and support NSS) in order to achieve
1040 any mappings of SID to dynamically allocated UNIX ids. This was
1041 a conscious design choice.
1043 3) New functions have been added to winbindd to emulate the 'add user
1044 script' family of smbd functions without requiring that external
1045 scripts be defined. This functionality is controlled by the 'winbind
1046 enable local accounts' smb.conf parameter (enabled by default).
1048 However, this account management functionality is only supported
1049 in a local tdb (winbindd_idmap.tdb). If these new UNIX accounts
1050 must be shared among multiple Samba servers (such as a PDC and BDCs),
1051 it will be necessary to define your own 'add user script', et. al.
1052 programs that place the accounts/groups in some form of directory
1053 such as NIS or LDAP. This requirement was deemed beyond the scope
1054 of winbind's account management functions. Solutions for
1055 distributing UNIX system information have been deployed and tested
1056 for many years. We saw no need to reinvent the wheel.
1058 4) A member of a Samba controlled domain running winbindd is now able
1059 to map domain users directly onto existing UNIX accounts while still
1060 automatically creating accounts for trusted users and groups. This
1061 behavior is controlled by the 'winbind trusted domains only' smb.conf
1062 parameter (disabled by default to provide 2.2.x winbind behavior).
1064 5) Group mapping support is wrapped in the local_XX_to_XX() functions
1065 in smbd/uid.c. The reason that group mappings are not included
1066 in winbindd is because the purpose of Samba's group map is to
1067 match any Windows SID with an existing UNIX group. These UNIX
1068 groups can be created by winbindd (see next section), but the
1069 SID<->gid mapping is retreived by smbd, not winbindd.
1075 * security = server running winbindd to allocate accounts on demand
1077 * Samba PDC running winbindd to handle the automatic creation of UNIX
1078 identities for machine trust accounts
1080 * Automtically creating UNIX user and groups when migrating a Windows NT
1081 4.0 PDC to a Samba PDC. Winbindd must be running when executing
1082 'net rpc vampire' for this to work.
