301 Release Notes for Samba 3.0.2a
303 ==============================
305 Samba 3.0.2a is a minor patch release for the 3.0.2 code base
306 to address, in particular, a problem when using pdbedit to
307 sanitize (--force-initialized-passwords) Samba's tdbsam
308 backend. This is the latest stable release of Samba. This
309 is the version that all production Samba servers should be
310 running for all current bug-fixes.
312 ******************* Attention! Achtung! Kree! *********************
314 Beginning with Samba 3.0.2, passwords for accounts with a last
315 change time (LCT-XXX in smbpasswd, sambaPwdLastSet attribute in
316 ldapsam, etc...) of zero (0) will be regarded as uninitialized
317 strings. This will cause authentication to fail for such
318 accounts. If you have valid passwords that meet this criteria,
319 you must update the last change time to a non-zero value. If you
320 do not, then 'pdbedit --force-initialized-passwords' will disable
321 these accounts and reset the password hashes to a string of X's.
323 ******************* Attention! Achtung! Kree! *********************

346 are written to the DIT.
349 o Gerald (Jerry) Carter <jerry@samba.org>
350 * Fixed iterator in tdbsam.
351 * Fix bug that disabled accounts with a valid NT password
352 hash, but no LanMan hash.
355 o Steve French <sfrench@us.ibm.com>
356 * Added missing nosetuid and noexec options.
359 o Bostjan Golob <golob@gimb.org>
360 * BUG 1046: Don't overwrite usernames of entries returned
364 o Sebastian Krahmer <krahmer@suse.de>

378 =============================
379 Release Notes for Samba 3.0.2
381 =============================
383 It has been confirmed that previous versions of Samba 3.0 are
384 susceptible to a password initialization bug that could grant an
385 attacker unauthorized access to a user account created by the
386 mksmbpasswd.sh shell script.
388 The Common Vulnerabilities and Exposures project (cve.mitre.org)
389 has assigned the name CAN-2004-0082 to this issue.
391 Samba administrators not wishing to upgrade to the current
392 version should download the 3.0.2 release, build the pdbedit
395 root# pdbedit-3.0.2 --force-initialized-passwords
397 This will disable all accounts not possessing a valid password
398 (e.g. the password field has been set a string of X's).
400 Samba servers running 3.0.2 are not vulnerable to this bug
401 regardless of whether or not pdbedit has been used to sanitize
404 Some of the more visible bugs in 3.0.1 addressed in the 3.0.2
407 o Joining a Samba domain from Pre-SP2 Windows 2000 clients.
408 o Logging onto a Samba domain from Windows XP clients.
409 o Problems with the %U and %u smb.conf variables in relation to
410 Windows 9x/ME clients.
411 o Kerberos failures due to an invalid in memory keytab detection
413 o Updates to the ntlm_auth tool.
414 o Fixes for various SMB signing errors.
415 o Better separation of WINS and DNS queries for domain controllers.

417 o Several crash bugs in smbd and winbindd.
418 o Output formatting fixes for smbclient for better compatibility
419 with scripts based on the 2.2 version.

897 o Adds a variant of the winbindd_getgroups() call called
898 winbindd_getusersids() that provides direct SID->SIDs listing of
899 a users supplementary groups. This is enough to allow non-Samba
900 applications to do ACL checking.

991 The original 3.0.0 release notes follow
992 =======================================
993 WHATS NEW IN Samba 3.0.0
995 =======================================
1001 1) Active Directory support. Samba 3.0 is now able to
1002 join a ADS realm as a member server and authenticate
1003 users using LDAP/Kerberos.
1005 2) Unicode support. Samba will now negotiate UNICODE on the wire
1006 and internally there is now a much better infrastructure for
1007 multi-byte and UNICODE character sets.
1009 3) New authentication system. The internal authentication system
1010 has been almost completely rewritten. Most of the changes are
1011 internal, but the new auth system is also very configurable.
1013 4) New default filename mangling system.
1015 5) A new "net" command has been added. It is somewhat similar to
1016 the "net" command in windows. Eventually we plan to replace
1017 numerous other utilities (such as smbpasswd) with subcommands
1020 6) Samba now negotiates NT-style status32 codes on the wire. This
1021 improves error handling a lot.
1023 7) Better Windows 2000/XP/2003 printing support including publishing
1024 printer attributes in active directory.
1026 8) New loadable module support for passdb backends and character
1029 9) New default dual-daemon winbindd support for better performance.
1031 10) Support for migrating from a Windows NT 4.0 domain to a Samba
1032 domain and maintaining user, group and domain SIDs.
1034 11) Support for establishing trust relationships with Windows NT 4.0
1037 12) Initial support for a distributed Winbind architecture using
1038 an LDAP directory for storing SID to uid/gid mappings.
1040 13) Major updates to the Samba documentation tree.
1042 14) Full support for client and server SMB signing to ensure
1043 compatibility with default Windows 2003 security settings.
1045 15) Improvement of ACL mapping features based on code donated by
1046 Andreas Grünbacher.
1049 Plus lots of other improvements!
1052 Additional Documentation
1053 ------------------------
1055 Please refer to Samba documentation tree (included in the docs/
1056 subdirectory) for extensive explanations of installing, configuring
1057 and maintaining Samba 3.0 servers and clients. It is advised to
1058 begin with the Samba-HOWTO-Collection for overviews and specific
1059 tasks (the current book is up to approximately 400 pages) and to
1060 refer to the various man pages for information on individual options.
1062 We are very glad to be able to include the second edition of
1063 "Using Samba" by Jay Ts, Robert Eckstein, and David Collier-Brown
1064 (O'Reilly & Associates) in this release. The book is available
1065 on-line at http://samba.org/samba/docs/ and is included with
1066 the Samba Web Administration Tool (SWAT). Thanks to the authors and
1067 publisher for making "Using Samba" under the GNU Free Documentation
1071 ######################################################################
1072 Upgrading from a previous Samba 3.0 beta
1073 ########################################
1075 Beginning with Samba 3.0.0beta3, the RID allocation functions
1076 have been moved into winbindd. Previously these were handled
1077 by each passdb backend. This means that winbindd must be running
1078 to automatically allocate RIDs for users and/or groups. Otherwise,
1079 smbd will use the 2.2 algorithm for generating new RIDs.
1081 If you are using 'passdb backend = tdbsam' with a previous Samba
1082 3.0 beta release (or possibly alpha), it may be necessary to
1083 move the RID_COUNTER entry from /usr/local/samba/private/passdb.tdb
1084 to winbindd_idmap.tdb. To do this:
1086 1) Ensure that winbindd_idmap.tdb exists (launch winbindd at least
1088 2) build tdbtool by executing 'make tdbtool' in the source/tdb/
1090 3) run: (note that 'tdb>' is the tool's prompt for input)
1092 root# ./tdbtool /usr/local/samba/private/passdb.tdb
1093 tdb> show RID_COUNTER
1097 [000] 0A 52 00 00 .R.
1099 tdb> move RID_COUNTER /usr/local/samba/var/locks/winbindd_idmap.tdb
1103 If you are using 'passdb backend = ldapsam', it will be necessary to
1104 store idmap entries in the LDAP directory as well (i.e. idmap backend
1105 = ldap). Refer to the 'net idmap' command for more information on
1106 migrating SID<->UNIX id mappings from one backend to another.
1108 If the RID_COUNTER record does not exist, then these instructions are
1109 unneccessary and the new RID_COUNTER record will be correctly generated

1289 This section contains brief descriptions of any new databases
1290 introduced in Samba 3.0. Please remember to backup your existing
1291 ${lock directory}/*tdb before upgrading to Samba 3.0. Samba will
1292 upgrade databases as they are opened (if necessary), but downgrading
1293 from 3.0 to 2.2 is an unsupported path.
1295 Name Description Backup?
1296 ---- ----------- -------
1297 account_policy User policy settings yes
1298 gencache Generic caching db no
1299 group_mapping Mapping table from Windows yes
1300 groups/SID to unix groups
1301 winbindd_idmap ID map table from SIDS to UNIX yes
1303 namecache Name resolution cache entries no
1304 netsamlogon_cache Cache of NET_USER_INFO_3 structure no
1305 returned as part of a successful

1308 command' created on a per print
1310 registry Read-only samba registry skeleton no
1311 that provides support for exporting
1312 various db tables via the winreg RPCs
1318 The following issues are known changes in behavior between Samba 2.2 and
1319 Samba 3.0 that may affect certain installations of Samba.
1321 1) When operating as a member of a Windows domain, Samba 2.2 would
1322 map any users authenticated by the remote DC to the 'guest account'
1323 if a uid could not be obtained via the getpwnam() call. Samba 3.0
1324 rejects the connection as NT_STATUS_LOGON_FAILURE. There is no
1325 current work around to re-establish the 2.2 behavior.
1327 2) When adding machines to a Samba 2.2 controlled domain, the
1328 'add user script' was used to create the UNIX identity of the
1329 machine trust account. Samba 3.0 introduces a new 'add machine
1330 script' that must be specified for this purpose. Samba 3.0 will
1331 not fall back to using the 'add user script' in the absence of
1332 an 'add machine script'
1335 ######################################################################
1336 Passdb Backends and Authentication
1337 ##################################
1339 There have been a few new changes that Samba administrators should be
1340 aware of when moving to Samba 3.0.
1342 1) encrypted passwords have been enabled by default in order to
1343 inter-operate better with out-of-the-box Windows client
1344 installations. This does mean that either (a) a samba account
1345 must be created for each user, or (b) 'encrypt passwords = no'
1346 must be explicitly defined in smb.conf.
1348 2) Inclusion of new 'security = ads' option for integration
1349 with an Active Directory domain using the native Windows
1350 Kerberos 5 and LDAP protocols.
1352 MIT kerberos 1.3.1 supports the ARCFOUR-HMAC-MD5 encryption
1353 type which is neccessary for servers on which the
1354 administrator password has not been changed, or kerberos-enabled
1355 SMB connections to servers that require Kerberos SMB signing.
1356 Besides this one difference, either MIT or Heimdal Kerberos
1357 distributions are usable by Samba 3.0.
1360 Samba 3.0 also includes the possibility of setting up chains
1361 of authentication methods (auth methods) and account storage
1362 backends (passdb backend). Please refer to the smb.conf(5)
1363 man page for details. While both parameters assume sane default
1364 values, it is likely that you will need to understand what the
1365 values actually mean in order to ensure Samba operates correctly.
1367 The recommended passdb backends at this time are
1369 * smbpasswd - 2.2 compatible flat file format
1370 * tdbsam - attribute rich database intended as an smbpasswd
1371 replacement for stand alone servers
1372 * ldapsam - attribute rich account storage and retrieval
1373 backend utilizing an LDAP directory.
1374 * ldapsam_compat - a 2.2 backward compatible LDAP account
1377 Certain functions of the smbpasswd(8) tool have been split between the
1378 new smbpasswd(8) utility, the net(8) tool, and the new pdbedit(8)
1379 utility. See the respective man pages for details.

1386 This section outlines the new features affecting Samba / LDAP
1392 A new object class (sambaSamAccount) has been introduced to replace
1393 the old sambaAccount. This change aids us in the renaming of
1394 attributes to prevent clashes with attributes from other vendors.
1395 There is a conversion script (examples/LDAP/convertSambaAccount) to
1396 modify and LDIF file to the new schema.
1400 $ ldapsearch .... -b "ou=people,dc=..." > sambaAcct.ldif
1401 $ convertSambaAccount --sid=<Domain SID> \
1402 --input=sambaAcct.ldif --output=sambaSamAcct.ldif \
1403 --changetype=[modify|add]
1405 The <DOM SID> can be obtained by running 'net getlocalsid
1406 <DOMAINNAME>' on the Samba PDC as root. The changetype determines
1407 the format of the generated LDIF output--either create new entries
1408 or modify existing entries.
1410 The old sambaAccount schema may still be used by specifying the
1411 "ldapsam_compat" passdb backend. However, the sambaAccount and
1412 associated attributes have been moved to the historical section of
1413 the schema file and must be uncommented before use if needed.
1414 The 2.2 object class declaration for a sambaAccount has not changed
1415 in the 3.0 samba.schema file.
1417 Other new object classes and their uses include:
1419 * sambaDomain - domain information used to allocate rids
1420 for users and groups as necessary. The attributes are added
1421 in 'ldap suffix' directory entry automatically if
1422 an idmap uid/gid range has been set and the 'ldapsam'
1423 passdb backend has been selected.
1425 * sambaGroupMapping - an object representing the
1426 relationship between a posixGroup and a Windows
1427 group/SID. These entries are stored in the 'ldap
1428 group suffix' and managed by the 'net groupmap' command.
1430 * sambaUnixIdPool - created in the 'ldap idmap suffix' entry
1431 automatically and contains the next available 'idmap uid' and
1434 * sambaIdmapEntry - object storing a mapping between a
1435 SID and a UNIX uid/gid. These objects are created by the
1436 idmap_ldap module as needed.
1438 * sambaSidEntry - object representing a SID alone, as a Structural
1439 class on which to build the sambaIdmapEntry.
1442 New Suffix for Searching
1443 ------------------------
1445 The following new smb.conf parameters have been added to aid in directing
1446 certain LDAP queries when 'passdb backend = ldapsam://...' has been
1449 * ldap suffix - used to search for user and computer accounts
1450 * ldap user suffix - used to store user accounts
1451 * ldap machine suffix - used to store machine trust accounts
1452 * ldap group suffix - location of posixGroup/sambaGroupMapping entries
1453 * ldap idmap suffix - location of sambaIdmapEntry objects
1455 If an 'ldap suffix' is defined, it will be appended to all of the
1456 remaining sub-suffix parameters. In this case, the order of the suffix
1457 listings in smb.conf is important. Always place the 'ldap suffix' first
1460 Due to a limitation in Samba's smb.conf parsing, you should not surround
1461 the DN's with quotation marks.
1467 Samba 3.0 supports an ldap backend for the idmap subsystem. The
1468 following options would inform Samba that the idmap table should be
1469 stored on the directory server onterose in the "ou=idmap,dc=plainjoe,
1474 idmap backend = ldap:ldap://onterose/
1475 ldap idmap suffix = ou=idmap,dc=plainjoe,dc=org
1476 idmap uid = 40000-50000
1477 idmap gid = 40000-50000
1479 This configuration allows winbind installations on multiple servers to
1480 share a uid/gid number space, thus avoiding the interoperability problems
1481 with NFS that were present in Samba 2.2.

1486 Trust Relationships and a Samba Domain
1487 ######################################
1489 Samba 3.0.0beta2 is able to utilize winbindd as the means of
1490 allocating uids and gids to trusted users and groups. More
1491 information regarding Samba's support for establishing trust
1492 relationships can be found in the Samba-HOWTO-Collection included
1493 in the docs/ directory of this release.
1495 First create your Samba PDC and ensure that everything is
1496 working correctly before moving on the trusts.
1498 To establish Samba as the trusting domain (named SAMBA) from a Windows NT
1499 4.0 domain named WINDOWS:
1501 1) create the trust account for SAMBA in "User Manager for Domains"
1502 2) connect the trust from the Samba domain using
1503 'net rpc trustdom establish GLASS'
1505 To create a trustlationship with SAMBA as the trusted domain:
1507 1) create the initial trust account for GLASS using
1508 'smbpasswd -a -i GLASS'. You may need to create a UNIX
1509 account for GLASS$ prior to this step (depending on your
1510 local configuration).
1511 2) connect the trust from a WINDOWS DC using "User Manager
1514 Now join winbindd on the Samba PDC to the SAMBA domain using
1515 the normal steps for adding a Samba server to an NT4 domain:
1516 (note that smbd & nmbd must be running at this point)
1518 root# net rpc join -U root
1519 Password: <enter root password from smbpasswd file here>
1521 Start winbindd and test the join with 'wbinfo -t'.
1523 Now test the trust relationship by connecting to the SAMBA DC
1524 (e.g. POGO) as a user from the WINDOWS domain:
1526 $ smbclient //pogo/netlogon -U Administrator -W WINDOWS
1529 Now connect to the WINDOWS DC (e.g. CRYSTAL) as a Samba user:
1531 $ smbclient //crystal/netlogon -U root -W WINDOWS
1534 ######################################################################
1538 Beginning with Samba3.0.0beta3, winbindd has been given new account
1539 manage functionality equivalent to the 'add user script' family of
1540 smb.conf parameters. The idmap design has also been changed to
1541 centralize control of foreign SID lookups and matching to UNIX
1545 Brief Description of Changes
1546 ----------------------------
1548 1) The sid_to_uid() family of functions (smbd/uid.c) have been
1549 reverted to the 2.2.x design. This means that when resolving a
1550 SID to a UID or similar mapping:
1552 a) First consult winbindd
1553 b) perform a local lookup only if winbindd fails to
1554 return a successful answer
1556 There are some variations to this, but these two rules generally
1559 2) All idmap lookups have been moved into winbindd. This means that
1560 a server must run winbindd (and support NSS) in order to achieve
1561 any mappings of SID to dynamically allocated UNIX ids. This was
1562 a conscious design choice.
1564 3) New functions have been added to winbindd to emulate the 'add user
1565 script' family of smbd functions without requiring that external
1566 scripts be defined. This functionality is controlled by the 'winbind
1567 enable local accounts' smb.conf parameter (enabled by default).
1569 However, this account management functionality is only supported
1570 in a local tdb (winbindd_idmap.tdb). If these new UNIX accounts
1571 must be shared among multiple Samba servers (such as a PDC and BDCs),
1572 it will be necessary to define your own 'add user script', et. al.
1573 programs that place the accounts/groups in some form of directory
1574 such as NIS or LDAP. This requirement was deemed beyond the scope
1575 of winbind's account management functions. Solutions for
1576 distributing UNIX system information have been deployed and tested
1577 for many years. We saw no need to reinvent the wheel.
1579 4) A member of a Samba controlled domain running winbindd is now able
1580 to map domain users directly onto existing UNIX accounts while still
1581 automatically creating accounts for trusted users and groups. This
1582 behavior is controlled by the 'winbind trusted domains only' smb.conf
1583 parameter (disabled by default to provide 2.2.x winbind behavior).
1585 5) Group mapping support is wrapped in the local_XX_to_XX() functions
1586 in smbd/uid.c. The reason that group mappings are not included
1587 in winbindd is because the purpose of Samba's group map is to
1588 match any Windows SID with an existing UNIX group. These UNIX
1589 groups can be created by winbindd (see next section), but the
1590 SID<->gid mapping is retreived by smbd, not winbindd.
1596 * security = server running winbindd to allocate accounts on demand
1598 * Samba PDC running winbindd to handle the automatic creation of UNIX
1599 identities for machine trust accounts
1601 * Automtically creating UNIX user and groups when migrating a Windows NT
1602 4.0 PDC to a Samba PDC. Winbindd must be running when executing
1603 'net rpc vampire' for this to work.
