371 Release Notes for Samba 3.0.2a
373 ==============================
375 Samba 3.0.2a is a minor patch release for the 3.0.2 code base
376 to address, in particular, a problem when using pdbedit to
377 sanitize (--force-initialized-passwords) Samba's tdbsam
378 backend. This is the latest stable release of Samba. This
379 is the version that all production Samba servers should be
380 running for all current bug-fixes.
382 ******************* Attention! Achtung! Kree! *********************
384 Beginning with Samba 3.0.2, passwords for accounts with a last
385 change time (LCT-XXX in smbpasswd, sambaPwdLastSet attribute in
386 ldapsam, etc...) of zero (0) will be regarded as uninitialized
387 strings. This will cause authentication to fail for such
388 accounts. If you have valid passwords that meet this criteria,
389 you must update the last change time to a non-zero value. If you
390 do not, then 'pdbedit --force-initialized-passwords' will disable
391 these accounts and reset the password hashes to a string of X's.
393 ******************* Attention! Achtung! Kree! *********************
402 Please refer to the CVS log for the SAMBA_3_0 branch for complete
403 details. The list of changes per contributor are as follows:
406 o Jeremy Allison <jra@samba.org>
407 * Added paranoia checks in parsing code.
410 o Andrew Bartlet <abartlet@samba.org>
411 * Ensure that changes to uninitialized passwords in ldapsam
412 are written to the DIT.
415 o Gerald (Jerry) Carter <jerry@samba.org>
416 * Fixed iterator in tdbsam.
417 * Fix bug that disabled accounts with a valid NT password
418 hash, but no LanMan hash.
421 o Steve French <sfrench@us.ibm.com>
422 * Added missing nosetuid and noexec options.
425 o Bostjan Golob <golob@gimb.org>
426 * BUG 1046: Don't overwrite usernames of entries returned
430 o Sebastian Krahmer <krahmer@suse.de>
431 * Fixed potential crash bug in NTLMSSP parsing code.
434 o Tim Potter <tpot@samba.org>
435 * Fixed logic in tdb_brlock error checking.
438 o Urban Widmark <urban@teststation.com>
439 * Set nosuid,nodev flags in smbmnt by default.

444 =============================
445 Release Notes for Samba 3.0.2
447 =============================
449 It has been confirmed that previous versions of Samba 3.0 are
450 susceptible to a password initialization bug that could grant an
451 attacker unauthorized access to a user account created by the
452 mksmbpasswd.sh shell script.
454 The Common Vulnerabilities and Exposures project (cve.mitre.org)
455 has assigned the name CAN-2004-0082 to this issue.
457 Samba administrators not wishing to upgrade to the current
458 version should download the 3.0.2 release, build the pdbedit
461 root# pdbedit-3.0.2 --force-initialized-passwords
463 This will disable all accounts not possessing a valid password
464 (e.g. the password field has been set a string of X's).
466 Samba servers running 3.0.2 are not vulnerable to this bug
467 regardless of whether or not pdbedit has been used to sanitize
470 Some of the more visible bugs in 3.0.1 addressed in the 3.0.2
473 o Joining a Samba domain from Pre-SP2 Windows 2000 clients.
474 o Logging onto a Samba domain from Windows XP clients.
475 o Problems with the %U and %u smb.conf variables in relation to
476 Windows 9x/ME clients.
477 o Kerberos failures due to an invalid in memory keytab detection
479 o Updates to the ntlm_auth tool.
480 o Fixes for various SMB signing errors.
481 o Better separation of WINS and DNS queries for domain controllers.
482 o Issues with nss_winbind FreeBSD and Solaris.
483 o Several crash bugs in smbd and winbindd.
484 o Output formatting fixes for smbclient for better compatibility
485 with scripts based on the 2.2 version.

928 from the tdb backend.
929 o Patch to handle munged dial string for Windows 2000 TSE.
930 Thanks to Gaz de France, Direction de la Recherche, Service
931 Informatique Métier for their supporting this work by Aurelien

953 o Make sure we only enumerate group mapping entries (not
954 /etc/group) even when doing local aliases.
955 o Relax check on the pipe name in a dce/rpc bind response to work
956 around issues with establishing trusts to a Windows 2003 domain.
957 o Ensure we mangle names ending in '.' in hash2 mangling method.
958 o Correct parsing issues with munged dial string.
959 o Fix bugs in quota support for XFS.
960 o Add a cleaner method for applications that need to provide

963 o Adds a variant of the winbindd_getgroups() call called
964 winbindd_getusersids() that provides direct SID->SIDs listing of
965 a users supplementary groups. This is enough to allow non-Samba
966 applications to do ACL checking.
967 o Make sure we don't append the 'ldap suffix' when writing out the
968 'ldap XXX suffix' values in SWAT (bug 328).
969 o Fix renames across file systems.

1055 ######################################################################
1057 The original 3.0.0 release notes follow
1058 =======================================
1059 WHATS NEW IN Samba 3.0.0
1061 =======================================
1067 1) Active Directory support. Samba 3.0 is now able to
1068 join a ADS realm as a member server and authenticate
1069 users using LDAP/Kerberos.
1071 2) Unicode support. Samba will now negotiate UNICODE on the wire
1072 and internally there is now a much better infrastructure for
1073 multi-byte and UNICODE character sets.
1075 3) New authentication system. The internal authentication system
1076 has been almost completely rewritten. Most of the changes are
1077 internal, but the new auth system is also very configurable.
1079 4) New default filename mangling system.
1081 5) A new "net" command has been added. It is somewhat similar to
1082 the "net" command in windows. Eventually we plan to replace
1083 numerous other utilities (such as smbpasswd) with subcommands
1086 6) Samba now negotiates NT-style status32 codes on the wire. This
1087 improves error handling a lot.
1089 7) Better Windows 2000/XP/2003 printing support including publishing
1090 printer attributes in active directory.
1092 8) New loadable module support for passdb backends and character
1095 9) New default dual-daemon winbindd support for better performance.
1097 10) Support for migrating from a Windows NT 4.0 domain to a Samba
1098 domain and maintaining user, group and domain SIDs.
1100 11) Support for establishing trust relationships with Windows NT 4.0
1103 12) Initial support for a distributed Winbind architecture using
1104 an LDAP directory for storing SID to uid/gid mappings.
1106 13) Major updates to the Samba documentation tree.
1108 14) Full support for client and server SMB signing to ensure
1109 compatibility with default Windows 2003 security settings.
1111 15) Improvement of ACL mapping features based on code donated by
1112 Andreas Grünbacher.
1115 Plus lots of other improvements!
1118 Additional Documentation
1119 ------------------------
1121 Please refer to Samba documentation tree (included in the docs/
1122 subdirectory) for extensive explanations of installing, configuring
1123 and maintaining Samba 3.0 servers and clients. It is advised to
1124 begin with the Samba-HOWTO-Collection for overviews and specific
1125 tasks (the current book is up to approximately 400 pages) and to
1126 refer to the various man pages for information on individual options.
1128 We are very glad to be able to include the second edition of
1129 "Using Samba" by Jay Ts, Robert Eckstein, and David Collier-Brown
1130 (O'Reilly & Associates) in this release. The book is available
1131 on-line at http://samba.org/samba/docs/ and is included with
1132 the Samba Web Administration Tool (SWAT). Thanks to the authors and
1133 publisher for making "Using Samba" under the GNU Free Documentation
1137 ######################################################################
1138 Upgrading from a previous Samba 3.0 beta
1139 ########################################
1141 Beginning with Samba 3.0.0beta3, the RID allocation functions
1142 have been moved into winbindd. Previously these were handled
1143 by each passdb backend. This means that winbindd must be running
1144 to automatically allocate RIDs for users and/or groups. Otherwise,
1145 smbd will use the 2.2 algorithm for generating new RIDs.
1147 If you are using 'passdb backend = tdbsam' with a previous Samba
1148 3.0 beta release (or possibly alpha), it may be necessary to
1149 move the RID_COUNTER entry from /usr/local/samba/private/passdb.tdb
1150 to winbindd_idmap.tdb. To do this:
1152 1) Ensure that winbindd_idmap.tdb exists (launch winbindd at least
1154 2) build tdbtool by executing 'make tdbtool' in the source/tdb/
1156 3) run: (note that 'tdb>' is the tool's prompt for input)
1158 root# ./tdbtool /usr/local/samba/private/passdb.tdb
1159 tdb> show RID_COUNTER
1163 [000] 0A 52 00 00 .R.
1165 tdb> move RID_COUNTER /usr/local/samba/var/locks/winbindd_idmap.tdb
1169 If you are using 'passdb backend = ldapsam', it will be necessary to
1170 store idmap entries in the LDAP directory as well (i.e. idmap backend
1171 = ldap). Refer to the 'net idmap' command for more information on
1172 migrating SID<->UNIX id mappings from one backend to another.
1174 If the RID_COUNTER record does not exist, then these instructions are
1175 unneccessary and the new RID_COUNTER record will be correctly generated

1384 The following issues are known changes in behavior between Samba 2.2 and
1385 Samba 3.0 that may affect certain installations of Samba.
1387 1) When operating as a member of a Windows domain, Samba 2.2 would
1388 map any users authenticated by the remote DC to the 'guest account'
1389 if a uid could not be obtained via the getpwnam() call. Samba 3.0
1390 rejects the connection as NT_STATUS_LOGON_FAILURE. There is no
1391 current work around to re-establish the 2.2 behavior.
1393 2) When adding machines to a Samba 2.2 controlled domain, the
1394 'add user script' was used to create the UNIX identity of the
1395 machine trust account. Samba 3.0 introduces a new 'add machine
1396 script' that must be specified for this purpose. Samba 3.0 will
1397 not fall back to using the 'add user script' in the absence of
1398 an 'add machine script'

1402 Passdb Backends and Authentication
1403 ##################################
1405 There have been a few new changes that Samba administrators should be
1406 aware of when moving to Samba 3.0.
1408 1) encrypted passwords have been enabled by default in order to
1409 inter-operate better with out-of-the-box Windows client
1410 installations. This does mean that either (a) a samba account
1411 must be created for each user, or (b) 'encrypt passwords = no'
1412 must be explicitly defined in smb.conf.
1414 2) Inclusion of new 'security = ads' option for integration
1415 with an Active Directory domain using the native Windows
1416 Kerberos 5 and LDAP protocols.
1418 MIT kerberos 1.3.1 supports the ARCFOUR-HMAC-MD5 encryption
1419 type which is neccessary for servers on which the
1420 administrator password has not been changed, or kerberos-enabled
1421 SMB connections to servers that require Kerberos SMB signing.
1422 Besides this one difference, either MIT or Heimdal Kerberos
1423 distributions are usable by Samba 3.0.
1426 Samba 3.0 also includes the possibility of setting up chains
1427 of authentication methods (auth methods) and account storage
1428 backends (passdb backend). Please refer to the smb.conf(5)
1429 man page for details. While both parameters assume sane default
1430 values, it is likely that you will need to understand what the
1431 values actually mean in order to ensure Samba operates correctly.
1433 The recommended passdb backends at this time are
1435 * smbpasswd - 2.2 compatible flat file format
1436 * tdbsam - attribute rich database intended as an smbpasswd
1437 replacement for stand alone servers
1438 * ldapsam - attribute rich account storage and retrieval
1439 backend utilizing an LDAP directory.
1440 * ldapsam_compat - a 2.2 backward compatible LDAP account
1443 Certain functions of the smbpasswd(8) tool have been split between the
1444 new smbpasswd(8) utility, the net(8) tool, and the new pdbedit(8)
1445 utility. See the respective man pages for details.
1448 ######################################################################
1452 This section outlines the new features affecting Samba / LDAP
1458 A new object class (sambaSamAccount) has been introduced to replace
1459 the old sambaAccount. This change aids us in the renaming of
1460 attributes to prevent clashes with attributes from other vendors.
1461 There is a conversion script (examples/LDAP/convertSambaAccount) to
1462 modify and LDIF file to the new schema.
1466 $ ldapsearch .... -b "ou=people,dc=..." > sambaAcct.ldif
1467 $ convertSambaAccount --sid=<Domain SID> \
1468 --input=sambaAcct.ldif --output=sambaSamAcct.ldif \
1469 --changetype=[modify|add]
1471 The <DOM SID> can be obtained by running 'net getlocalsid
1472 <DOMAINNAME>' on the Samba PDC as root. The changetype determines
1473 the format of the generated LDIF output--either create new entries
1474 or modify existing entries.
1476 The old sambaAccount schema may still be used by specifying the
1477 "ldapsam_compat" passdb backend. However, the sambaAccount and
1478 associated attributes have been moved to the historical section of
1479 the schema file and must be uncommented before use if needed.
1480 The 2.2 object class declaration for a sambaAccount has not changed
1481 in the 3.0 samba.schema file.
1483 Other new object classes and their uses include:
1485 * sambaDomain - domain information used to allocate rids
1486 for users and groups as necessary. The attributes are added
1487 in 'ldap suffix' directory entry automatically if
1488 an idmap uid/gid range has been set and the 'ldapsam'
1489 passdb backend has been selected.
1491 * sambaGroupMapping - an object representing the
1492 relationship between a posixGroup and a Windows
1493 group/SID. These entries are stored in the 'ldap
1494 group suffix' and managed by the 'net groupmap' command.
1496 * sambaUnixIdPool - created in the 'ldap idmap suffix' entry
1497 automatically and contains the next available 'idmap uid' and
1500 * sambaIdmapEntry - object storing a mapping between a
1501 SID and a UNIX uid/gid. These objects are created by the
1502 idmap_ldap module as needed.
1504 * sambaSidEntry - object representing a SID alone, as a Structural
1505 class on which to build the sambaIdmapEntry.
1508 New Suffix for Searching
1509 ------------------------
1511 The following new smb.conf parameters have been added to aid in directing
1512 certain LDAP queries when 'passdb backend = ldapsam://...' has been
1515 * ldap suffix - used to search for user and computer accounts
1516 * ldap user suffix - used to store user accounts
1517 * ldap machine suffix - used to store machine trust accounts
1518 * ldap group suffix - location of posixGroup/sambaGroupMapping entries
1519 * ldap idmap suffix - location of sambaIdmapEntry objects
1521 If an 'ldap suffix' is defined, it will be appended to all of the
1522 remaining sub-suffix parameters. In this case, the order of the suffix
1523 listings in smb.conf is important. Always place the 'ldap suffix' first
1526 Due to a limitation in Samba's smb.conf parsing, you should not surround
1527 the DN's with quotation marks.
1533 Samba 3.0 supports an ldap backend for the idmap subsystem. The
1534 following options would inform Samba that the idmap table should be
1535 stored on the directory server onterose in the "ou=idmap,dc=plainjoe,
1540 idmap backend = ldap:ldap://onterose/
1541 ldap idmap suffix = ou=idmap,dc=plainjoe,dc=org
1542 idmap uid = 40000-50000
1543 idmap gid = 40000-50000
1545 This configuration allows winbind installations on multiple servers to
1546 share a uid/gid number space, thus avoiding the interoperability problems
1547 with NFS that were present in Samba 2.2.
1551 ######################################################################
1552 Trust Relationships and a Samba Domain
1553 ######################################
1555 Samba 3.0.0beta2 is able to utilize winbindd as the means of
1556 allocating uids and gids to trusted users and groups. More
1557 information regarding Samba's support for establishing trust
1558 relationships can be found in the Samba-HOWTO-Collection included
1559 in the docs/ directory of this release.
1561 First create your Samba PDC and ensure that everything is
1562 working correctly before moving on the trusts.
1564 To establish Samba as the trusting domain (named SAMBA) from a Windows NT
1565 4.0 domain named WINDOWS:
1567 1) create the trust account for SAMBA in "User Manager for Domains"
1568 2) connect the trust from the Samba domain using
1569 'net rpc trustdom establish GLASS'
1571 To create a trustlationship with SAMBA as the trusted domain:
1573 1) create the initial trust account for GLASS using
1574 'smbpasswd -a -i GLASS'. You may need to create a UNIX
1575 account for GLASS$ prior to this step (depending on your
1576 local configuration).
1577 2) connect the trust from a WINDOWS DC using "User Manager
1580 Now join winbindd on the Samba PDC to the SAMBA domain using
1581 the normal steps for adding a Samba server to an NT4 domain:
1582 (note that smbd & nmbd must be running at this point)
1584 root# net rpc join -U root
1585 Password: <enter root password from smbpasswd file here>
1587 Start winbindd and test the join with 'wbinfo -t'.
1589 Now test the trust relationship by connecting to the SAMBA DC
1590 (e.g. POGO) as a user from the WINDOWS domain:
1592 $ smbclient //pogo/netlogon -U Administrator -W WINDOWS
1595 Now connect to the WINDOWS DC (e.g. CRYSTAL) as a Samba user:
1597 $ smbclient //crystal/netlogon -U root -W WINDOWS
1600 ######################################################################
1604 Beginning with Samba3.0.0beta3, winbindd has been given new account
1605 manage functionality equivalent to the 'add user script' family of
1606 smb.conf parameters. The idmap design has also been changed to
1607 centralize control of foreign SID lookups and matching to UNIX
1611 Brief Description of Changes
1612 ----------------------------
1614 1) The sid_to_uid() family of functions (smbd/uid.c) have been
1615 reverted to the 2.2.x design. This means that when resolving a
1616 SID to a UID or similar mapping:
1618 a) First consult winbindd
1619 b) perform a local lookup only if winbindd fails to
1620 return a successful answer
1622 There are some variations to this, but these two rules generally
1625 2) All idmap lookups have been moved into winbindd. This means that
1626 a server must run winbindd (and support NSS) in order to achieve
1627 any mappings of SID to dynamically allocated UNIX ids. This was
1628 a conscious design choice.
1630 3) New functions have been added to winbindd to emulate the 'add user
1631 script' family of smbd functions without requiring that external
1632 scripts be defined. This functionality is controlled by the 'winbind
1633 enable local accounts' smb.conf parameter (enabled by default).
1635 However, this account management functionality is only supported
1636 in a local tdb (winbindd_idmap.tdb). If these new UNIX accounts
1637 must be shared among multiple Samba servers (such as a PDC and BDCs),
1638 it will be necessary to define your own 'add user script', et. al.
1639 programs that place the accounts/groups in some form of directory
1640 such as NIS or LDAP. This requirement was deemed beyond the scope
1641 of winbind's account management functions. Solutions for
1642 distributing UNIX system information have been deployed and tested
1643 for many years. We saw no need to reinvent the wheel.
1645 4) A member of a Samba controlled domain running winbindd is now able
1646 to map domain users directly onto existing UNIX accounts while still
1647 automatically creating accounts for trusted users and groups. This
1648 behavior is controlled by the 'winbind trusted domains only' smb.conf
1649 parameter (disabled by default to provide 2.2.x winbind behavior).
1651 5) Group mapping support is wrapped in the local_XX_to_XX() functions
1652 in smbd/uid.c. The reason that group mappings are not included
1653 in winbindd is because the purpose of Samba's group map is to
1654 match any Windows SID with an existing UNIX group. These UNIX
1655 groups can be created by winbindd (see next section), but the
1656 SID<->gid mapping is retreived by smbd, not winbindd.
1662 * security = server running winbindd to allocate accounts on demand
1664 * Samba PDC running winbindd to handle the automatic creation of UNIX
1665 identities for machine trust accounts
1667 * Automtically creating UNIX user and groups when migrating a Windows NT
1668 4.0 PDC to a Samba PDC. Winbindd must be running when executing
1669 'net rpc vampire' for this to work.
