375 Release Notes for Samba 3.0.2a
376 February 13, 2004
377 ==============================
379 Samba 3.0.2a is a minor patch release for the 3.0.2 code base
380 to address, in particular, a problem when using pdbedit to
381 sanitize (--force-initialized-passwords) Samba's tdbsam
382 backend. This is the latest stable release of Samba. This
383 is the version that all production Samba servers should be
384 running for all current bug-fixes.
386 ******************* Attention! Achtung! Kree! *********************
388 Beginning with Samba 3.0.2, passwords for accounts with a last
389 change time (LCT-XXX in smbpasswd, sambaPwdLastSet attribute in
390 ldapsam, etc...) of zero (0) will be regarded as uninitialized
391 strings. This will cause authentication to fail for such
392 accounts. If you have valid passwords that meet this criteria,
393 you must update the last change time to a non-zero value. If you
394 do not, then 'pdbedit --force-initialized-passwords' will disable
395 these accounts and reset the password hashes to a string of X's.
397 ******************* Attention! Achtung! Kree! *********************

448 =============================
449 Release Notes for Samba 3.0.2
450 February 9, 2004
451 =============================
453 It has been confirmed that previous versions of Samba 3.0 are
454 susceptible to a password initialization bug that could grant an
455 attacker unauthorized access to a user account created by the
456 mksmbpasswd.sh shell script.
458 The Common Vulnerabilities and Exposures project (cve.mitre.org)
459 has assigned the name CAN-2004-0082 to this issue.
461 Samba administrators not wishing to upgrade to the current
462 version should download the 3.0.2 release, build the pdbedit
463 tool, and run
465 root# pdbedit-3.0.2 --force-initialized-passwords
467 This will disable all accounts not possessing a valid password
468 (e.g. the password field has been set a string of X's).
470 Samba servers running 3.0.2 are not vulnerable to this bug
471 regardless of whether or not pdbedit has been used to sanitize
472 the passdb backend.
474 Some of the more visible bugs in 3.0.1 addressed in the 3.0.2
475 release include:
477 o Joining a Samba domain from Pre-SP2 Windows 2000 clients.
478 o Logging onto a Samba domain from Windows XP clients.
479 o Problems with the %U and %u smb.conf variables in relation to
480 Windows 9x/ME clients.
481 o Kerberos failures due to an invalid in memory keytab detection
482 test.
483 o Updates to the ntlm_auth tool.
484 o Fixes for various SMB signing errors.
485 o Better separation of WINS and DNS queries for domain controllers.
486 o Issues with nss_winbind FreeBSD and Solaris.
487 o Several crash bugs in smbd and winbindd.
488 o Output formatting fixes for smbclient for better compatibility
489 with scripts based on the 2.2 version.

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

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

950 monitor used by Windows NT and later clients (bug 660).
951 o Fix several reported problems with point-n-print from
952 Windows 2000/XP clients due to a bug in the EnumPrinterDataEx()
953 reply (bug 338, 527 & 643).
954 o Fix a handful of potential memory leaks in the LDAP code used
955 by ldapsam[_compat] and the LDAP idmap backend.
956 o Fix for pdbedit error code returns (bug 763).
957 o Make sure we only enumerate group mapping entries (not
958 /etc/group) even when doing local aliases.
959 o Relax check on the pipe name in a dce/rpc bind response to work
960 around issues with establishing trusts to a Windows 2003 domain.
961 o Ensure we mangle names ending in '.' in hash2 mangling method.
962 o Correct parsing issues with munged dial string.
963 o Fix bugs in quota support for XFS.
964 o Add a cleaner method for applications that need to provide
965 name->SID mappings to do this via NSS rather than having to
966 know the winbindd pipe protocol.
967 o Adds a variant of the winbindd_getgroups() call called
968 winbindd_getusersids() that provides direct SID->SIDs listing of
969 a users supplementary groups. This is enough to allow non-Samba
970 applications to do ACL checking.
971 o Make sure we don't append the 'ldap suffix' when writing out the
972 'ldap XXX suffix' values in SWAT (bug 328).
973 o Fix renames across file systems.
974 o Ensure that items in a list of strings containing whitespace are
975 written out surrounded by single quotes. This means that both
976 double and single quotes are now used to surround strings in
977 smb.conf (bug 481).
978 o Enable SWAT to correctly determine if winbindd is running (bug
979 398).

991 authentication.
992 o Change the name of the job passed off to cups from "Test Page"
993 to "smbprn.00000033 Test Page" so that we can get the smb
994 jobid back. This allow users to delete jobs with cups printing
995 backend (partial work on bug 770).
996 o Fix build of winbindd with static pdb modules.
997 o Retrieve the correct ACL group bits if the file has an ACL
998 (bug 802).
999 o Implement "net rpc group members": Get members of a domain group
1000 in human-readable format.
1001 o Add MacOSX (Darwin) specific charset module code.

1020 this call whether we have a complete PDU or not; fixes bug
1021 with multiple PDU request rpc's broken over SMBwriteX calls
1022 each.
1023 o Fix incorrect smb flags2 for connections to pre-NT servers
1024 (causes smbclient to fail to OS2 for example) (bug 821).

1061 The original 3.0.0 release notes follow
1062 =======================================
1063 WHATS NEW IN Samba 3.0.0
1064 September 24, 2003
1065 =======================================
1068 Major new features:
1069 -------------------
1071 1) Active Directory support. Samba 3.0 is now able to
1072 join a ADS realm as a member server and authenticate
1073 users using LDAP/Kerberos.
1075 2) Unicode support. Samba will now negotiate UNICODE on the wire
1076 and internally there is now a much better infrastructure for
1077 multi-byte and UNICODE character sets.
1079 3) New authentication system. The internal authentication system
1080 has been almost completely rewritten. Most of the changes are
1081 internal, but the new auth system is also very configurable.
1083 4) New default filename mangling system.
1085 5) A new "net" command has been added. It is somewhat similar to
1086 the "net" command in windows. Eventually we plan to replace
1087 numerous other utilities (such as smbpasswd) with subcommands
1088 in "net".
1090 6) Samba now negotiates NT-style status32 codes on the wire. This
1091 improves error handling a lot.
1093 7) Better Windows 2000/XP/2003 printing support including publishing
1094 printer attributes in active directory.
1096 8) New loadable module support for passdb backends and character
1097 sets.
1099 9) New default dual-daemon winbindd support for better performance.
1101 10) Support for migrating from a Windows NT 4.0 domain to a Samba
1102 domain and maintaining user, group and domain SIDs.
1104 11) Support for establishing trust relationships with Windows NT 4.0
1105 domain controllers.
1107 12) Initial support for a distributed Winbind architecture using
1108 an LDAP directory for storing SID to uid/gid mappings.
1110 13) Major updates to the Samba documentation tree.
1112 14) Full support for client and server SMB signing to ensure
1113 compatibility with default Windows 2003 security settings.
1115 15) Improvement of ACL mapping features based on code donated by
1116 Andreas Grünbacher.
1119 Plus lots of other improvements!
1122 Additional Documentation
1123 ------------------------
1125 Please refer to Samba documentation tree (included in the docs/
1126 subdirectory) for extensive explanations of installing, configuring
1127 and maintaining Samba 3.0 servers and clients. It is advised to
1128 begin with the Samba-HOWTO-Collection for overviews and specific
1129 tasks (the current book is up to approximately 400 pages) and to
1130 refer to the various man pages for information on individual options.
1132 We are very glad to be able to include the second edition of
1133 "Using Samba" by Jay Ts, Robert Eckstein, and David Collier-Brown
1134 (O'Reilly & Associates) in this release. The book is available
1135 on-line at http://samba.org/samba/docs/ and is included with
1136 the Samba Web Administration Tool (SWAT). Thanks to the authors and
1137 publisher for making "Using Samba" under the GNU Free Documentation
1138 License.
1141 ######################################################################
1142 Upgrading from a previous Samba 3.0 beta
1143 ########################################
1145 Beginning with Samba 3.0.0beta3, the RID allocation functions
1146 have been moved into winbindd. Previously these were handled
1147 by each passdb backend. This means that winbindd must be running
1148 to automatically allocate RIDs for users and/or groups. Otherwise,
1149 smbd will use the 2.2 algorithm for generating new RIDs.
1151 If you are using 'passdb backend = tdbsam' with a previous Samba
1152 3.0 beta release (or possibly alpha), it may be necessary to
1153 move the RID_COUNTER entry from /usr/local/samba/private/passdb.tdb
1154 to winbindd_idmap.tdb. To do this:
1156 1) Ensure that winbindd_idmap.tdb exists (launch winbindd at least
1157 once)
1158 2) build tdbtool by executing 'make tdbtool' in the source/tdb/

1361 ${lock directory}/*tdb before upgrading to Samba 3.0. Samba will
1362 upgrade databases as they are opened (if necessary), but downgrading
1363 from 3.0 to 2.2 is an unsupported path.
1365 Name Description Backup?
1366 ---- ----------- -------
1367 account_policy User policy settings yes
1368 gencache Generic caching db no
1369 group_mapping Mapping table from Windows yes
1370 groups/SID to unix groups
1371 winbindd_idmap ID map table from SIDS to UNIX yes
1372 uids/gids.
1373 namecache Name resolution cache entries no
1374 netsamlogon_cache Cache of NET_USER_INFO_3 structure no
1375 returned as part of a successful
1376 net_sam_logon request
1377 printing/*.tdb Cached output from 'lpq no
1378 command' created on a per print
1379 service basis
1380 registry Read-only samba registry skeleton no
1381 that provides support for exporting
1382 various db tables via the winreg RPCs
1385 Changes in Behavior
1386 -------------------
1388 The following issues are known changes in behavior between Samba 2.2 and
1389 Samba 3.0 that may affect certain installations of Samba.
1391 1) When operating as a member of a Windows domain, Samba 2.2 would
1392 map any users authenticated by the remote DC to the 'guest account'
1393 if a uid could not be obtained via the getpwnam() call. Samba 3.0
1394 rejects the connection as NT_STATUS_LOGON_FAILURE. There is no
1395 current work around to re-establish the 2.2 behavior.
1397 2) When adding machines to a Samba 2.2 controlled domain, the
1398 'add user script' was used to create the UNIX identity of the
1399 machine trust account. Samba 3.0 introduces a new 'add machine
1400 script' that must be specified for this purpose. Samba 3.0 will
1401 not fall back to using the 'add user script' in the absence of
1402 an 'add machine script'
1405 ######################################################################
1406 Passdb Backends and Authentication
1407 ##################################
1409 There have been a few new changes that Samba administrators should be
1410 aware of when moving to Samba 3.0.
1412 1) encrypted passwords have been enabled by default in order to
1413 inter-operate better with out-of-the-box Windows client
1414 installations. This does mean that either (a) a samba account
1415 must be created for each user, or (b) 'encrypt passwords = no'
1416 must be explicitly defined in smb.conf.
1418 2) Inclusion of new 'security = ads' option for integration
1419 with an Active Directory domain using the native Windows
1420 Kerberos 5 and LDAP protocols.
1422 MIT kerberos 1.3.1 supports the ARCFOUR-HMAC-MD5 encryption
1423 type which is neccessary for servers on which the
1424 administrator password has not been changed, or kerberos-enabled
1425 SMB connections to servers that require Kerberos SMB signing.
1426 Besides this one difference, either MIT or Heimdal Kerberos
1427 distributions are usable by Samba 3.0.
1430 Samba 3.0 also includes the possibility of setting up chains
1431 of authentication methods (auth methods) and account storage
1432 backends (passdb backend). Please refer to the smb.conf(5)
1433 man page for details. While both parameters assume sane default
1434 values, it is likely that you will need to understand what the
1435 values actually mean in order to ensure Samba operates correctly.
1437 The recommended passdb backends at this time are
1439 * smbpasswd - 2.2 compatible flat file format
1440 * tdbsam - attribute rich database intended as an smbpasswd
1441 replacement for stand alone servers
1442 * ldapsam - attribute rich account storage and retrieval
1443 backend utilizing an LDAP directory.
1444 * ldapsam_compat - a 2.2 backward compatible LDAP account
1445 backend
1447 Certain functions of the smbpasswd(8) tool have been split between the
1448 new smbpasswd(8) utility, the net(8) tool, and the new pdbedit(8)
1449 utility. See the respective man pages for details.
1452 ######################################################################
1453 LDAP
1454 ####
1456 This section outlines the new features affecting Samba / LDAP
1457 integration.
1459 New Schema
1460 ----------
1462 A new object class (sambaSamAccount) has been introduced to replace
1463 the old sambaAccount. This change aids us in the renaming of
1464 attributes to prevent clashes with attributes from other vendors.
1465 There is a conversion script (examples/LDAP/convertSambaAccount) to
1466 modify and LDIF file to the new schema.
1468 Example:
1470 $ ldapsearch .... -b "ou=people,dc=..." > sambaAcct.ldif
1471 $ convertSambaAccount --sid=<Domain SID> \
1472 --input=sambaAcct.ldif --output=sambaSamAcct.ldif \
1473 --changetype=[modify|add]
1475 The <DOM SID> can be obtained by running 'net getlocalsid
1476 <DOMAINNAME>' on the Samba PDC as root. The changetype determines
1477 the format of the generated LDIF output--either create new entries
1478 or modify existing entries.
1480 The old sambaAccount schema may still be used by specifying the
1481 "ldapsam_compat" passdb backend. However, the sambaAccount and
1482 associated attributes have been moved to the historical section of
1483 the schema file and must be uncommented before use if needed.
1484 The 2.2 object class declaration for a sambaAccount has not changed
1485 in the 3.0 samba.schema file.
1487 Other new object classes and their uses include:
1489 * sambaDomain - domain information used to allocate rids
1490 for users and groups as necessary. The attributes are added
1491 in 'ldap suffix' directory entry automatically if
1492 an idmap uid/gid range has been set and the 'ldapsam'
1493 passdb backend has been selected.
1495 * sambaGroupMapping - an object representing the
1496 relationship between a posixGroup and a Windows
1497 group/SID. These entries are stored in the 'ldap
1498 group suffix' and managed by the 'net groupmap' command.
1500 * sambaUnixIdPool - created in the 'ldap idmap suffix' entry
1501 automatically and contains the next available 'idmap uid' and
1502 'idmap gid'
1504 * sambaIdmapEntry - object storing a mapping between a
1505 SID and a UNIX uid/gid. These objects are created by the
1506 idmap_ldap module as needed.
1508 * sambaSidEntry - object representing a SID alone, as a Structural
1509 class on which to build the sambaIdmapEntry.
1512 New Suffix for Searching
1513 ------------------------
1515 The following new smb.conf parameters have been added to aid in directing
1516 certain LDAP queries when 'passdb backend = ldapsam://...' has been
1517 specified.
1519 * ldap suffix - used to search for user and computer accounts
1520 * ldap user suffix - used to store user accounts
1521 * ldap machine suffix - used to store machine trust accounts
1522 * ldap group suffix - location of posixGroup/sambaGroupMapping entries
1523 * ldap idmap suffix - location of sambaIdmapEntry objects
1525 If an 'ldap suffix' is defined, it will be appended to all of the
1526 remaining sub-suffix parameters. In this case, the order of the suffix
1527 listings in smb.conf is important. Always place the 'ldap suffix' first
1528 in the list.
1530 Due to a limitation in Samba's smb.conf parsing, you should not surround
1531 the DN's with quotation marks.
1534 IdMap LDAP support
1535 ------------------
1537 Samba 3.0 supports an ldap backend for the idmap subsystem. The
1538 following options would inform Samba that the idmap table should be
1539 stored on the directory server onterose in the "ou=idmap,dc=plainjoe,
1540 dc=org" partition.
1542 [global]
1543 ...
1544 idmap backend = ldap:ldap://onterose/
1545 ldap idmap suffix = ou=idmap,dc=plainjoe,dc=org
1546 idmap uid = 40000-50000
1547 idmap gid = 40000-50000
1549 This configuration allows winbind installations on multiple servers to
1550 share a uid/gid number space, thus avoiding the interoperability problems
1551 with NFS that were present in Samba 2.2.
1555 ######################################################################
1556 Trust Relationships and a Samba Domain
1557 ######################################
1559 Samba 3.0.0beta2 is able to utilize winbindd as the means of
1560 allocating uids and gids to trusted users and groups. More
1561 information regarding Samba's support for establishing trust
1562 relationships can be found in the Samba-HOWTO-Collection included
1563 in the docs/ directory of this release.
1565 First create your Samba PDC and ensure that everything is
1566 working correctly before moving on the trusts.
1568 To establish Samba as the trusting domain (named SAMBA) from a Windows NT
1569 4.0 domain named WINDOWS:
1571 1) create the trust account for SAMBA in "User Manager for Domains"
1572 2) connect the trust from the Samba domain using
1573 'net rpc trustdom establish GLASS'
1575 To create a trustlationship with SAMBA as the trusted domain:
1577 1) create the initial trust account for GLASS using
1578 'smbpasswd -a -i GLASS'. You may need to create a UNIX
1579 account for GLASS$ prior to this step (depending on your
1580 local configuration).
1581 2) connect the trust from a WINDOWS DC using "User Manager
1582 for Domains"
1584 Now join winbindd on the Samba PDC to the SAMBA domain using
1585 the normal steps for adding a Samba server to an NT4 domain:
1586 (note that smbd & nmbd must be running at this point)
1588 root# net rpc join -U root
1589 Password: <enter root password from smbpasswd file here>
1591 Start winbindd and test the join with 'wbinfo -t'.
1593 Now test the trust relationship by connecting to the SAMBA DC
1594 (e.g. POGO) as a user from the WINDOWS domain:
1596 $ smbclient //pogo/netlogon -U Administrator -W WINDOWS
1597 Password:
1599 Now connect to the WINDOWS DC (e.g. CRYSTAL) as a Samba user:
1601 $ smbclient //crystal/netlogon -U root -W WINDOWS
1602 Password:
1604 ######################################################################
1605 Changes in Winbind
1606 ##################
1608 Beginning with Samba3.0.0beta3, winbindd has been given new account
1609 manage functionality equivalent to the 'add user script' family of
1610 smb.conf parameters. The idmap design has also been changed to
1611 centralize control of foreign SID lookups and matching to UNIX
1612 uids and gids.
1615 Brief Description of Changes
1616 ----------------------------
1618 1) The sid_to_uid() family of functions (smbd/uid.c) have been
1619 reverted to the 2.2.x design. This means that when resolving a
1620 SID to a UID or similar mapping:
1622 a) First consult winbindd
1623 b) perform a local lookup only if winbindd fails to
1624 return a successful answer
1626 There are some variations to this, but these two rules generally
1627 apply.
1629 2) All idmap lookups have been moved into winbindd. This means that
1630 a server must run winbindd (and support NSS) in order to achieve
1631 any mappings of SID to dynamically allocated UNIX ids. This was
1632 a conscious design choice.
1634 3) New functions have been added to winbindd to emulate the 'add user
1635 script' family of smbd functions without requiring that external
1636 scripts be defined. This functionality is controlled by the 'winbind
1637 enable local accounts' smb.conf parameter (enabled by default).
1639 However, this account management functionality is only supported
1640 in a local tdb (winbindd_idmap.tdb). If these new UNIX accounts
1641 must be shared among multiple Samba servers (such as a PDC and BDCs),
1642 it will be necessary to define your own 'add user script', et. al.
1643 programs that place the accounts/groups in some form of directory
1644 such as NIS or LDAP. This requirement was deemed beyond the scope
1645 of winbind's account management functions. Solutions for
1646 distributing UNIX system information have been deployed and tested
1647 for many years. We saw no need to reinvent the wheel.
1649 4) A member of a Samba controlled domain running winbindd is now able
1650 to map domain users directly onto existing UNIX accounts while still
1651 automatically creating accounts for trusted users and groups. This
1652 behavior is controlled by the 'winbind trusted domains only' smb.conf
1653 parameter (disabled by default to provide 2.2.x winbind behavior).
1655 5) Group mapping support is wrapped in the local_XX_to_XX() functions
1656 in smbd/uid.c. The reason that group mappings are not included
1657 in winbindd is because the purpose of Samba's group map is to
1658 match any Windows SID with an existing UNIX group. These UNIX
1659 groups can be created by winbindd (see next section), but the
1660 SID<->gid mapping is retreived by smbd, not winbindd.
1663 Examples
1664 --------
1666 * security = server running winbindd to allocate accounts on demand
1668 * Samba PDC running winbindd to handle the automatic creation of UNIX
1669 identities for machine trust accounts
1671 * Automtically creating UNIX user and groups when migrating a Windows NT
1672 4.0 PDC to a Samba PDC. Winbindd must be running when executing
1673 'net rpc vampire' for this to work.
