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

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

931 'winbind trusted domains only = yes' (bug 680).
932 o Remove code in idmap_ldap that searches the user suffix and group
933 suffix. It's not needed and provides inconsistent functionality
934 from the tdb backend.
935 o Patch to handle munged dial string for Windows 2000 TSE.
936 Thanks to Gaz de France, Direction de la Recherche, Service
937 Informatique Métier for their supporting this work by Aurelien

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

952 monitor used by Windows NT and later clients (bug 660).
953 o Fix several reported problems with point-n-print from
954 Windows 2000/XP clients due to a bug in the EnumPrinterDataEx()
955 reply (bug 338, 527 & 643).
956 o Fix a handful of potential memory leaks in the LDAP code used
957 by ldapsam[_compat] and the LDAP idmap backend.
958 o Fix for pdbedit error code returns (bug 763).
959 o Make sure we only enumerate group mapping entries (not
960 /etc/group) even when doing local aliases.
961 o Relax check on the pipe name in a dce/rpc bind response to work
962 around issues with establishing trusts to a Windows 2003 domain.
963 o Ensure we mangle names ending in '.' in hash2 mangling method.
964 o Correct parsing issues with munged dial string.
965 o Fix bugs in quota support for XFS.
966 o Add a cleaner method for applications that need to provide
967 name->SID mappings to do this via NSS rather than having to
968 know the winbindd pipe protocol.
969 o Adds a variant of the winbindd_getgroups() call called
970 winbindd_getusersids() that provides direct SID->SIDs listing of
971 a users supplementary groups. This is enough to allow non-Samba
972 applications to do ACL checking.
973 o Make sure we don't append the 'ldap suffix' when writing out the
974 'ldap XXX suffix' values in SWAT (bug 328).
975 o Fix renames across file systems.
976 o Ensure that items in a list of strings containing whitespace are
977 written out surrounded by single quotes. This means that both
978 double and single quotes are now used to surround strings in
979 smb.conf (bug 481).
980 o Enable SWAT to correctly determine if winbindd is running (bug
981 398).

991 o Disable NTLM2 for RPC pipes.
992 o Allow the client to specify the NTLM2 flags got NTLMSSP
993 authentication.
994 o Change the name of the job passed off to cups from "Test Page"
995 to "smbprn.00000033 Test Page" so that we can get the smb
996 jobid back. This allow users to delete jobs with cups printing
997 backend (partial work on bug 770).
998 o Fix build of winbindd with static pdb modules.
999 o Retrieve the correct ACL group bits if the file has an ACL
1000 (bug 802).
1001 o Implement "net rpc group members": Get members of a domain group
1002 in human-readable format.
1003 o Add MacOSX (Darwin) specific charset module code.

1020 o Support munged dial for ldapsam (bug 800).
1021 o Fix process_incoming_data() to return the number of bytes handled
1022 this call whether we have a complete PDU or not; fixes bug
1023 with multiple PDU request rpc's broken over SMBwriteX calls
1024 each.
1025 o Fix incorrect smb flags2 for connections to pre-NT servers
1026 (causes smbclient to fail to OS2 for example) (bug 821).

1061 ######################################################################
1063 The original 3.0.0 release notes follow
1064 =======================================
1065 WHATS NEW IN Samba 3.0.0
1066 September 24, 2003
1067 =======================================
1070 Major new features:
1071 -------------------
1073 1) Active Directory support. Samba 3.0 is now able to
1074 join a ADS realm as a member server and authenticate
1075 users using LDAP/Kerberos.
1077 2) Unicode support. Samba will now negotiate UNICODE on the wire
1078 and internally there is now a much better infrastructure for
1079 multi-byte and UNICODE character sets.
1081 3) New authentication system. The internal authentication system
1082 has been almost completely rewritten. Most of the changes are
1083 internal, but the new auth system is also very configurable.
1085 4) New default filename mangling system.
1087 5) A new "net" command has been added. It is somewhat similar to
1088 the "net" command in windows. Eventually we plan to replace
1089 numerous other utilities (such as smbpasswd) with subcommands
1090 in "net".
1092 6) Samba now negotiates NT-style status32 codes on the wire. This
1093 improves error handling a lot.
1095 7) Better Windows 2000/XP/2003 printing support including publishing
1096 printer attributes in active directory.
1098 8) New loadable module support for passdb backends and character
1099 sets.
1101 9) New default dual-daemon winbindd support for better performance.
1103 10) Support for migrating from a Windows NT 4.0 domain to a Samba
1104 domain and maintaining user, group and domain SIDs.
1106 11) Support for establishing trust relationships with Windows NT 4.0
1107 domain controllers.
1109 12) Initial support for a distributed Winbind architecture using
1110 an LDAP directory for storing SID to uid/gid mappings.
1112 13) Major updates to the Samba documentation tree.
1114 14) Full support for client and server SMB signing to ensure
1115 compatibility with default Windows 2003 security settings.
1117 15) Improvement of ACL mapping features based on code donated by
1118 Andreas Grünbacher.
1121 Plus lots of other improvements!
1124 Additional Documentation
1125 ------------------------
1127 Please refer to Samba documentation tree (included in the docs/
1128 subdirectory) for extensive explanations of installing, configuring
1129 and maintaining Samba 3.0 servers and clients. It is advised to
1130 begin with the Samba-HOWTO-Collection for overviews and specific
1131 tasks (the current book is up to approximately 400 pages) and to
1132 refer to the various man pages for information on individual options.
1134 We are very glad to be able to include the second edition of
1135 "Using Samba" by Jay Ts, Robert Eckstein, and David Collier-Brown
1136 (O'Reilly & Associates) in this release. The book is available
1137 on-line at http://samba.org/samba/docs/ and is included with
1138 the Samba Web Administration Tool (SWAT). Thanks to the authors and
1139 publisher for making "Using Samba" under the GNU Free Documentation
1140 License.
1143 ######################################################################
1144 Upgrading from a previous Samba 3.0 beta
1145 ########################################
1147 Beginning with Samba 3.0.0beta3, the RID allocation functions
1148 have been moved into winbindd. Previously these were handled
1149 by each passdb backend. This means that winbindd must be running
1150 to automatically allocate RIDs for users and/or groups. Otherwise,
1151 smbd will use the 2.2 algorithm for generating new RIDs.
1153 If you are using 'passdb backend = tdbsam' with a previous Samba
1154 3.0 beta release (or possibly alpha), it may be necessary to
1155 move the RID_COUNTER entry from /usr/local/samba/private/passdb.tdb
1156 to winbindd_idmap.tdb. To do this:
1158 1) Ensure that winbindd_idmap.tdb exists (launch winbindd at least

1173 record moved
1175 If you are using 'passdb backend = ldapsam', it will be necessary to
1176 store idmap entries in the LDAP directory as well (i.e. idmap backend
1177 = ldap). Refer to the 'net idmap' command for more information on
1178 migrating SID<->UNIX id mappings from one backend to another.
1180 If the RID_COUNTER record does not exist, then these instructions are
1181 unneccessary and the new RID_COUNTER record will be correctly generated
1182 if needed.

1363 ${lock directory}/*tdb before upgrading to Samba 3.0. Samba will
1364 upgrade databases as they are opened (if necessary), but downgrading
1365 from 3.0 to 2.2 is an unsupported path.
1367 Name Description Backup?
1368 ---- ----------- -------
1369 account_policy User policy settings yes
1370 gencache Generic caching db no
1371 group_mapping Mapping table from Windows yes
1372 groups/SID to unix groups
1373 winbindd_idmap ID map table from SIDS to UNIX yes
1374 uids/gids.
1375 namecache Name resolution cache entries no
1376 netsamlogon_cache Cache of NET_USER_INFO_3 structure no
1377 returned as part of a successful
1378 net_sam_logon request
1379 printing/*.tdb Cached output from 'lpq no
1380 command' created on a per print
1381 service basis
1382 registry Read-only samba registry skeleton no
1383 that provides support for exporting
1384 various db tables via the winreg RPCs
1387 Changes in Behavior
1388 -------------------
1390 The following issues are known changes in behavior between Samba 2.2 and
1391 Samba 3.0 that may affect certain installations of Samba.
1393 1) When operating as a member of a Windows domain, Samba 2.2 would
1394 map any users authenticated by the remote DC to the 'guest account'
1395 if a uid could not be obtained via the getpwnam() call. Samba 3.0
1396 rejects the connection as NT_STATUS_LOGON_FAILURE. There is no
1397 current work around to re-establish the 2.2 behavior.
1399 2) When adding machines to a Samba 2.2 controlled domain, the
1400 'add user script' was used to create the UNIX identity of the
1401 machine trust account. Samba 3.0 introduces a new 'add machine
1402 script' that must be specified for this purpose. Samba 3.0 will
1403 not fall back to using the 'add user script' in the absence of
1404 an 'add machine script'
1407 ######################################################################
1408 Passdb Backends and Authentication
1409 ##################################
1411 There have been a few new changes that Samba administrators should be
1412 aware of when moving to Samba 3.0.
1414 1) encrypted passwords have been enabled by default in order to
1415 inter-operate better with out-of-the-box Windows client
1416 installations. This does mean that either (a) a samba account
1417 must be created for each user, or (b) 'encrypt passwords = no'
1418 must be explicitly defined in smb.conf.
1420 2) Inclusion of new 'security = ads' option for integration
1421 with an Active Directory domain using the native Windows
1422 Kerberos 5 and LDAP protocols.
1424 MIT kerberos 1.3.1 supports the ARCFOUR-HMAC-MD5 encryption
1425 type which is neccessary for servers on which the
1426 administrator password has not been changed, or kerberos-enabled
1427 SMB connections to servers that require Kerberos SMB signing.
1428 Besides this one difference, either MIT or Heimdal Kerberos
1429 distributions are usable by Samba 3.0.
1432 Samba 3.0 also includes the possibility of setting up chains
1433 of authentication methods (auth methods) and account storage
1434 backends (passdb backend). Please refer to the smb.conf(5)
1435 man page for details. While both parameters assume sane default
1436 values, it is likely that you will need to understand what the
1437 values actually mean in order to ensure Samba operates correctly.
1439 The recommended passdb backends at this time are
1441 * smbpasswd - 2.2 compatible flat file format
1442 * tdbsam - attribute rich database intended as an smbpasswd
1443 replacement for stand alone servers
1444 * ldapsam - attribute rich account storage and retrieval
1445 backend utilizing an LDAP directory.
1446 * ldapsam_compat - a 2.2 backward compatible LDAP account
1447 backend
1449 Certain functions of the smbpasswd(8) tool have been split between the
1450 new smbpasswd(8) utility, the net(8) tool, and the new pdbedit(8)
1451 utility. See the respective man pages for details.
1454 ######################################################################
1455 LDAP
1456 ####
1458 This section outlines the new features affecting Samba / LDAP
1459 integration.
1461 New Schema
1462 ----------
1464 A new object class (sambaSamAccount) has been introduced to replace
1465 the old sambaAccount. This change aids us in the renaming of
1466 attributes to prevent clashes with attributes from other vendors.
1467 There is a conversion script (examples/LDAP/convertSambaAccount) to
1468 modify and LDIF file to the new schema.
1470 Example:
1472 $ ldapsearch .... -b "ou=people,dc=..." > sambaAcct.ldif
1473 $ convertSambaAccount --sid=<Domain SID> \
1474 --input=sambaAcct.ldif --output=sambaSamAcct.ldif \
1475 --changetype=[modify|add]
1477 The <DOM SID> can be obtained by running 'net getlocalsid
1478 <DOMAINNAME>' on the Samba PDC as root. The changetype determines
1479 the format of the generated LDIF output--either create new entries
1480 or modify existing entries.
1482 The old sambaAccount schema may still be used by specifying the
1483 "ldapsam_compat" passdb backend. However, the sambaAccount and
1484 associated attributes have been moved to the historical section of
1485 the schema file and must be uncommented before use if needed.
1486 The 2.2 object class declaration for a sambaAccount has not changed
1487 in the 3.0 samba.schema file.
1489 Other new object classes and their uses include:
1491 * sambaDomain - domain information used to allocate rids
1492 for users and groups as necessary. The attributes are added
1493 in 'ldap suffix' directory entry automatically if
1494 an idmap uid/gid range has been set and the 'ldapsam'
1495 passdb backend has been selected.
1497 * sambaGroupMapping - an object representing the
1498 relationship between a posixGroup and a Windows
1499 group/SID. These entries are stored in the 'ldap
1500 group suffix' and managed by the 'net groupmap' command.
1502 * sambaUnixIdPool - created in the 'ldap idmap suffix' entry
1503 automatically and contains the next available 'idmap uid' and
1504 'idmap gid'
1506 * sambaIdmapEntry - object storing a mapping between a
1507 SID and a UNIX uid/gid. These objects are created by the
1508 idmap_ldap module as needed.
1510 * sambaSidEntry - object representing a SID alone, as a Structural
1511 class on which to build the sambaIdmapEntry.
1514 New Suffix for Searching
1515 ------------------------
1517 The following new smb.conf parameters have been added to aid in directing
1518 certain LDAP queries when 'passdb backend = ldapsam://...' has been
1519 specified.
1521 * ldap suffix - used to search for user and computer accounts
1522 * ldap user suffix - used to store user accounts
1523 * ldap machine suffix - used to store machine trust accounts
1524 * ldap group suffix - location of posixGroup/sambaGroupMapping entries
1525 * ldap idmap suffix - location of sambaIdmapEntry objects
1527 If an 'ldap suffix' is defined, it will be appended to all of the
1528 remaining sub-suffix parameters. In this case, the order of the suffix
1529 listings in smb.conf is important. Always place the 'ldap suffix' first
1530 in the list.
1532 Due to a limitation in Samba's smb.conf parsing, you should not surround
1533 the DN's with quotation marks.
1536 IdMap LDAP support
1537 ------------------
1539 Samba 3.0 supports an ldap backend for the idmap subsystem. The
1540 following options would inform Samba that the idmap table should be
1541 stored on the directory server onterose in the "ou=idmap,dc=plainjoe,
1542 dc=org" partition.
1544 [global]
1545 ...
1546 idmap backend = ldap:ldap://onterose/
1547 ldap idmap suffix = ou=idmap,dc=plainjoe,dc=org
1548 idmap uid = 40000-50000
1549 idmap gid = 40000-50000
1551 This configuration allows winbind installations on multiple servers to
1552 share a uid/gid number space, thus avoiding the interoperability problems
1553 with NFS that were present in Samba 2.2.
1557 ######################################################################
1558 Trust Relationships and a Samba Domain
1559 ######################################
1561 Samba 3.0.0beta2 is able to utilize winbindd as the means of
1562 allocating uids and gids to trusted users and groups. More
1563 information regarding Samba's support for establishing trust
1564 relationships can be found in the Samba-HOWTO-Collection included
1565 in the docs/ directory of this release.
1567 First create your Samba PDC and ensure that everything is
1568 working correctly before moving on the trusts.
1570 To establish Samba as the trusting domain (named SAMBA) from a Windows NT
1571 4.0 domain named WINDOWS:
1573 1) create the trust account for SAMBA in "User Manager for Domains"
1574 2) connect the trust from the Samba domain using
1575 'net rpc trustdom establish GLASS'
1577 To create a trustlationship with SAMBA as the trusted domain:
1579 1) create the initial trust account for GLASS using
1580 'smbpasswd -a -i GLASS'. You may need to create a UNIX
1581 account for GLASS$ prior to this step (depending on your
1582 local configuration).
1583 2) connect the trust from a WINDOWS DC using "User Manager
1584 for Domains"
1586 Now join winbindd on the Samba PDC to the SAMBA domain using
1587 the normal steps for adding a Samba server to an NT4 domain:
1588 (note that smbd & nmbd must be running at this point)
1590 root# net rpc join -U root
1591 Password: <enter root password from smbpasswd file here>
1593 Start winbindd and test the join with 'wbinfo -t'.
1595 Now test the trust relationship by connecting to the SAMBA DC
1596 (e.g. POGO) as a user from the WINDOWS domain:
1598 $ smbclient //pogo/netlogon -U Administrator -W WINDOWS
1599 Password:
1601 Now connect to the WINDOWS DC (e.g. CRYSTAL) as a Samba user:
1603 $ smbclient //crystal/netlogon -U root -W WINDOWS
1604 Password:
1606 ######################################################################
1607 Changes in Winbind
1608 ##################
1610 Beginning with Samba3.0.0beta3, winbindd has been given new account
1611 manage functionality equivalent to the 'add user script' family of
1612 smb.conf parameters. The idmap design has also been changed to
1613 centralize control of foreign SID lookups and matching to UNIX
1614 uids and gids.
1617 Brief Description of Changes
1618 ----------------------------
1620 1) The sid_to_uid() family of functions (smbd/uid.c) have been
1621 reverted to the 2.2.x design. This means that when resolving a
1622 SID to a UID or similar mapping:
1624 a) First consult winbindd
1625 b) perform a local lookup only if winbindd fails to
1626 return a successful answer
1628 There are some variations to this, but these two rules generally
1629 apply.
1631 2) All idmap lookups have been moved into winbindd. This means that
1632 a server must run winbindd (and support NSS) in order to achieve
1633 any mappings of SID to dynamically allocated UNIX ids. This was
1634 a conscious design choice.
1636 3) New functions have been added to winbindd to emulate the 'add user
1637 script' family of smbd functions without requiring that external
1638 scripts be defined. This functionality is controlled by the 'winbind
1639 enable local accounts' smb.conf parameter (enabled by default).
1641 However, this account management functionality is only supported
1642 in a local tdb (winbindd_idmap.tdb). If these new UNIX accounts
1643 must be shared among multiple Samba servers (such as a PDC and BDCs),
1644 it will be necessary to define your own 'add user script', et. al.
1645 programs that place the accounts/groups in some form of directory
1646 such as NIS or LDAP. This requirement was deemed beyond the scope
1647 of winbind's account management functions. Solutions for
1648 distributing UNIX system information have been deployed and tested
1649 for many years. We saw no need to reinvent the wheel.
1651 4) A member of a Samba controlled domain running winbindd is now able
1652 to map domain users directly onto existing UNIX accounts while still
1653 automatically creating accounts for trusted users and groups. This
1654 behavior is controlled by the 'winbind trusted domains only' smb.conf
1655 parameter (disabled by default to provide 2.2.x winbind behavior).
1657 5) Group mapping support is wrapped in the local_XX_to_XX() functions
1658 in smbd/uid.c. The reason that group mappings are not included
1659 in winbindd is because the purpose of Samba's group map is to
1660 match any Windows SID with an existing UNIX group. These UNIX
1661 groups can be created by winbindd (see next section), but the
1662 SID<->gid mapping is retreived by smbd, not winbindd.
1665 Examples
1666 --------
1668 * security = server running winbindd to allocate accounts on demand
1670 * Samba PDC running winbindd to handle the automatic creation of UNIX
1671 identities for machine trust accounts
1673 * Automtically creating UNIX user and groups when migrating a Windows NT
1674 4.0 PDC to a Samba PDC. Winbindd must be running when executing
1675 'net rpc vampire' for this to work.
