420 Release Notes for Samba 3.0.2a
422 ==============================
424 Samba 3.0.2a is a minor patch release for the 3.0.2 code base
425 to address, in particular, a problem when using pdbedit to
426 sanitize (--force-initialized-passwords) Samba's tdbsam
427 backend. This is the latest stable release of Samba. This
428 is the version that all production Samba servers should be
429 running for all current bug-fixes.
431 ******************* Attention! Achtung! Kree! *********************
433 Beginning with Samba 3.0.2, passwords for accounts with a last
434 change time (LCT-XXX in smbpasswd, sambaPwdLastSet attribute in
435 ldapsam, etc...) of zero (0) will be regarded as uninitialized
436 strings. This will cause authentication to fail for such
437 accounts. If you have valid passwords that meet this criteria,
438 you must update the last change time to a non-zero value. If you
439 do not, then 'pdbedit --force-initialized-passwords' will disable
440 these accounts and reset the password hashes to a string of X's.
442 ******************* Attention! Achtung! Kree! *********************
451 Please refer to the CVS log for the SAMBA_3_0 branch for complete
452 details. The list of changes per contributor are as follows:
455 o Jeremy Allison <jra@samba.org>
456 * Added paranoia checks in parsing code.
459 o Andrew Bartlet <abartlet@samba.org>
460 * Ensure that changes to uninitialized passwords in ldapsam
461 are written to the DIT.
464 o Gerald (Jerry) Carter <jerry@samba.org>
465 * Fixed iterator in tdbsam.
466 * Fix bug that disabled accounts with a valid NT password
467 hash, but no LanMan hash.
470 o Steve French <sfrench@us.ibm.com>
471 * Added missing nosetuid and noexec options.
474 o Bostjan Golob <golob@gimb.org>
475 * BUG 1046: Don't overwrite usernames of entries returned
479 o Sebastian Krahmer <krahmer@suse.de>
480 * Fixed potential crash bug in NTLMSSP parsing code.
483 o Tim Potter <tpot@samba.org>
484 * Fixed logic in tdb_brlock error checking.
487 o Urban Widmark <urban@teststation.com>
488 * Set nosuid,nodev flags in smbmnt by default.

493 =============================
494 Release Notes for Samba 3.0.2
496 =============================
498 It has been confirmed that previous versions of Samba 3.0 are
499 susceptible to a password initialization bug that could grant an
500 attacker unauthorized access to a user account created by the
501 mksmbpasswd.sh shell script.
503 The Common Vulnerabilities and Exposures project (cve.mitre.org)
504 has assigned the name CAN-2004-0082 to this issue.
506 Samba administrators not wishing to upgrade to the current
507 version should download the 3.0.2 release, build the pdbedit
510 root# pdbedit-3.0.2 --force-initialized-passwords
512 This will disable all accounts not possessing a valid password
513 (e.g. the password field has been set a string of X's).
515 Samba servers running 3.0.2 are not vulnerable to this bug
516 regardless of whether or not pdbedit has been used to sanitize
519 Some of the more visible bugs in 3.0.1 addressed in the 3.0.2
522 o Joining a Samba domain from Pre-SP2 Windows 2000 clients.
523 o Logging onto a Samba domain from Windows XP clients.
524 o Problems with the %U and %u smb.conf variables in relation to
525 Windows 9x/ME clients.
526 o Kerberos failures due to an invalid in memory keytab detection
528 o Updates to the ntlm_auth tool.
529 o Fixes for various SMB signing errors.
530 o Better separation of WINS and DNS queries for domain controllers.
531 o Issues with nss_winbind FreeBSD and Solaris.
532 o Several crash bugs in smbd and winbindd.
533 o Output formatting fixes for smbclient for better compatibility
534 with scripts based on the 2.2 version.

1003 /etc/group) even when doing local aliases.
1004 o Relax check on the pipe name in a dce/rpc bind response to work
1005 around issues with establishing trusts to a Windows 2003 domain.
1006 o Ensure we mangle names ending in '.' in hash2 mangling method.
1007 o Correct parsing issues with munged dial string.
1008 o Fix bugs in quota support for XFS.
1009 o Add a cleaner method for applications that need to provide

1011 know the winbindd pipe protocol.
1012 o Adds a variant of the winbindd_getgroups() call called
1013 winbindd_getusersids() that provides direct SID->SIDs listing of
1014 a users supplementary groups. This is enough to allow non-Samba
1015 applications to do ACL checking.
1016 o Make sure we don't append the 'ldap suffix' when writing out the
1017 'ldap XXX suffix' values in SWAT (bug 328).
1018 o Fix renames across file systems.

1104 ######################################################################
1106 The original 3.0.0 release notes follow
1107 =======================================
1108 WHATS NEW IN Samba 3.0.0
1110 =======================================
1116 1) Active Directory support. Samba 3.0 is now able to
1117 join a ADS realm as a member server and authenticate
1118 users using LDAP/Kerberos.
1120 2) Unicode support. Samba will now negotiate UNICODE on the wire
1121 and internally there is now a much better infrastructure for
1122 multi-byte and UNICODE character sets.
1124 3) New authentication system. The internal authentication system
1125 has been almost completely rewritten. Most of the changes are
1126 internal, but the new auth system is also very configurable.
1128 4) New default filename mangling system.
1130 5) A new "net" command has been added. It is somewhat similar to
1131 the "net" command in windows. Eventually we plan to replace
1132 numerous other utilities (such as smbpasswd) with subcommands
1135 6) Samba now negotiates NT-style status32 codes on the wire. This
1136 improves error handling a lot.
1138 7) Better Windows 2000/XP/2003 printing support including publishing
1139 printer attributes in active directory.
1141 8) New loadable module support for passdb backends and character
1144 9) New default dual-daemon winbindd support for better performance.
1146 10) Support for migrating from a Windows NT 4.0 domain to a Samba
1147 domain and maintaining user, group and domain SIDs.
1149 11) Support for establishing trust relationships with Windows NT 4.0
1152 12) Initial support for a distributed Winbind architecture using
1153 an LDAP directory for storing SID to uid/gid mappings.
1155 13) Major updates to the Samba documentation tree.
1157 14) Full support for client and server SMB signing to ensure
1158 compatibility with default Windows 2003 security settings.
1160 15) Improvement of ACL mapping features based on code donated by
1161 Andreas Grünbacher.
1164 Plus lots of other improvements!
1167 Additional Documentation
1168 ------------------------
1170 Please refer to Samba documentation tree (included in the docs/
1171 subdirectory) for extensive explanations of installing, configuring
1172 and maintaining Samba 3.0 servers and clients. It is advised to
1173 begin with the Samba-HOWTO-Collection for overviews and specific
1174 tasks (the current book is up to approximately 400 pages) and to
1175 refer to the various man pages for information on individual options.
1177 We are very glad to be able to include the second edition of
1178 "Using Samba" by Jay Ts, Robert Eckstein, and David Collier-Brown
1179 (O'Reilly & Associates) in this release. The book is available
1180 on-line at http://samba.org/samba/docs/ and is included with
1181 the Samba Web Administration Tool (SWAT). Thanks to the authors and
1182 publisher for making "Using Samba" under the GNU Free Documentation
1186 ######################################################################
1187 Upgrading from a previous Samba 3.0 beta
1188 ########################################
1190 Beginning with Samba 3.0.0beta3, the RID allocation functions
1191 have been moved into winbindd. Previously these were handled
1192 by each passdb backend. This means that winbindd must be running
1193 to automatically allocate RIDs for users and/or groups. Otherwise,
1194 smbd will use the 2.2 algorithm for generating new RIDs.
1196 If you are using 'passdb backend = tdbsam' with a previous Samba
1197 3.0 beta release (or possibly alpha), it may be necessary to
1198 move the RID_COUNTER entry from /usr/local/samba/private/passdb.tdb
1199 to winbindd_idmap.tdb. To do this:
1201 1) Ensure that winbindd_idmap.tdb exists (launch winbindd at least
1203 2) build tdbtool by executing 'make tdbtool' in the source/tdb/
1205 3) run: (note that 'tdb>' is the tool's prompt for input)
1207 root# ./tdbtool /usr/local/samba/private/passdb.tdb
1208 tdb> show RID_COUNTER
1212 [000] 0A 52 00 00 .R.
1214 tdb> move RID_COUNTER /usr/local/samba/var/locks/winbindd_idmap.tdb
1218 If you are using 'passdb backend = ldapsam', it will be necessary to
1219 store idmap entries in the LDAP directory as well (i.e. idmap backend
1220 = ldap). Refer to the 'net idmap' command for more information on
1221 migrating SID<->UNIX id mappings from one backend to another.
1223 If the RID_COUNTER record does not exist, then these instructions are
1224 unneccessary and the new RID_COUNTER record will be correctly generated

1230 Upgrading from Samba 2.2
1231 ########################
1233 This section is provided to help administrators understand the details
1234 involved with upgrading a Samba 2.2 server to Samba 3.0.

1404 This section contains brief descriptions of any new databases
1405 introduced in Samba 3.0. Please remember to backup your existing
1406 ${lock directory}/*tdb before upgrading to Samba 3.0. Samba will
1407 upgrade databases as they are opened (if necessary), but downgrading
1408 from 3.0 to 2.2 is an unsupported path.

1426 that provides support for exporting
1427 various db tables via the winreg RPCs
1433 The following issues are known changes in behavior between Samba 2.2 and
1434 Samba 3.0 that may affect certain installations of Samba.
1436 1) When operating as a member of a Windows domain, Samba 2.2 would
1437 map any users authenticated by the remote DC to the 'guest account'
1438 if a uid could not be obtained via the getpwnam() call. Samba 3.0
1439 rejects the connection as NT_STATUS_LOGON_FAILURE. There is no
1440 current work around to re-establish the 2.2 behavior.
1442 2) When adding machines to a Samba 2.2 controlled domain, the
1443 'add user script' was used to create the UNIX identity of the
1444 machine trust account. Samba 3.0 introduces a new 'add machine
1445 script' that must be specified for this purpose. Samba 3.0 will
1446 not fall back to using the 'add user script' in the absence of
1447 an 'add machine script'
1450 ######################################################################
1451 Passdb Backends and Authentication
1452 ##################################
1454 There have been a few new changes that Samba administrators should be
1455 aware of when moving to Samba 3.0.
1457 1) encrypted passwords have been enabled by default in order to
1458 inter-operate better with out-of-the-box Windows client
1459 installations. This does mean that either (a) a samba account
1460 must be created for each user, or (b) 'encrypt passwords = no'
1461 must be explicitly defined in smb.conf.
1463 2) Inclusion of new 'security = ads' option for integration
1464 with an Active Directory domain using the native Windows
1465 Kerberos 5 and LDAP protocols.
1467 MIT kerberos 1.3.1 supports the ARCFOUR-HMAC-MD5 encryption
1468 type which is neccessary for servers on which the
1469 administrator password has not been changed, or kerberos-enabled
1470 SMB connections to servers that require Kerberos SMB signing.
1471 Besides this one difference, either MIT or Heimdal Kerberos
1472 distributions are usable by Samba 3.0.
1475 Samba 3.0 also includes the possibility of setting up chains
1476 of authentication methods (auth methods) and account storage
1477 backends (passdb backend). Please refer to the smb.conf(5)
1478 man page for details. While both parameters assume sane default
1479 values, it is likely that you will need to understand what the
1480 values actually mean in order to ensure Samba operates correctly.
1482 The recommended passdb backends at this time are
1484 * smbpasswd - 2.2 compatible flat file format
1485 * tdbsam - attribute rich database intended as an smbpasswd
1486 replacement for stand alone servers
1487 * ldapsam - attribute rich account storage and retrieval
1488 backend utilizing an LDAP directory.
1489 * ldapsam_compat - a 2.2 backward compatible LDAP account
1492 Certain functions of the smbpasswd(8) tool have been split between the
1493 new smbpasswd(8) utility, the net(8) tool, and the new pdbedit(8)
1494 utility. See the respective man pages for details.
1497 ######################################################################
1501 This section outlines the new features affecting Samba / LDAP
1507 A new object class (sambaSamAccount) has been introduced to replace
1508 the old sambaAccount. This change aids us in the renaming of
1509 attributes to prevent clashes with attributes from other vendors.
1510 There is a conversion script (examples/LDAP/convertSambaAccount) to
1511 modify and LDIF file to the new schema.
1515 $ ldapsearch .... -b "ou=people,dc=..." > sambaAcct.ldif
1516 $ convertSambaAccount --sid=<Domain SID> \
1517 --input=sambaAcct.ldif --output=sambaSamAcct.ldif \
1518 --changetype=[modify|add]
1520 The <DOM SID> can be obtained by running 'net getlocalsid
1521 <DOMAINNAME>' on the Samba PDC as root. The changetype determines
1522 the format of the generated LDIF output--either create new entries
1523 or modify existing entries.
1525 The old sambaAccount schema may still be used by specifying the
1526 "ldapsam_compat" passdb backend. However, the sambaAccount and
1527 associated attributes have been moved to the historical section of
1528 the schema file and must be uncommented before use if needed.
1529 The 2.2 object class declaration for a sambaAccount has not changed
1530 in the 3.0 samba.schema file.
1532 Other new object classes and their uses include:
1534 * sambaDomain - domain information used to allocate rids
1535 for users and groups as necessary. The attributes are added
1536 in 'ldap suffix' directory entry automatically if
1537 an idmap uid/gid range has been set and the 'ldapsam'
1538 passdb backend has been selected.
1540 * sambaGroupMapping - an object representing the
1541 relationship between a posixGroup and a Windows
1542 group/SID. These entries are stored in the 'ldap
1543 group suffix' and managed by the 'net groupmap' command.
1545 * sambaUnixIdPool - created in the 'ldap idmap suffix' entry
1546 automatically and contains the next available 'idmap uid' and
1549 * sambaIdmapEntry - object storing a mapping between a
1550 SID and a UNIX uid/gid. These objects are created by the
1551 idmap_ldap module as needed.
1553 * sambaSidEntry - object representing a SID alone, as a Structural
1554 class on which to build the sambaIdmapEntry.
1557 New Suffix for Searching
1558 ------------------------
1560 The following new smb.conf parameters have been added to aid in directing
1561 certain LDAP queries when 'passdb backend = ldapsam://...' has been
1564 * ldap suffix - used to search for user and computer accounts
1565 * ldap user suffix - used to store user accounts
1566 * ldap machine suffix - used to store machine trust accounts
1567 * ldap group suffix - location of posixGroup/sambaGroupMapping entries
1568 * ldap idmap suffix - location of sambaIdmapEntry objects
1570 If an 'ldap suffix' is defined, it will be appended to all of the
1571 remaining sub-suffix parameters. In this case, the order of the suffix
1572 listings in smb.conf is important. Always place the 'ldap suffix' first
1575 Due to a limitation in Samba's smb.conf parsing, you should not surround
1576 the DN's with quotation marks.
1582 Samba 3.0 supports an ldap backend for the idmap subsystem. The
1583 following options would inform Samba that the idmap table should be
1584 stored on the directory server onterose in the "ou=idmap,dc=plainjoe,
1589 idmap backend = ldap:ldap://onterose/
1590 ldap idmap suffix = ou=idmap,dc=plainjoe,dc=org
1591 idmap uid = 40000-50000
1592 idmap gid = 40000-50000
1594 This configuration allows winbind installations on multiple servers to
1595 share a uid/gid number space, thus avoiding the interoperability problems
1596 with NFS that were present in Samba 2.2.
1600 ######################################################################
1601 Trust Relationships and a Samba Domain
1602 ######################################
1604 Samba 3.0.0beta2 is able to utilize winbindd as the means of
1605 allocating uids and gids to trusted users and groups. More
1606 information regarding Samba's support for establishing trust
1607 relationships can be found in the Samba-HOWTO-Collection included
1608 in the docs/ directory of this release.
1610 First create your Samba PDC and ensure that everything is
1611 working correctly before moving on the trusts.
1613 To establish Samba as the trusting domain (named SAMBA) from a Windows NT
1614 4.0 domain named WINDOWS:
1616 1) create the trust account for SAMBA in "User Manager for Domains"
1617 2) connect the trust from the Samba domain using
1618 'net rpc trustdom establish GLASS'
1620 To create a trustlationship with SAMBA as the trusted domain:
1622 1) create the initial trust account for GLASS using
1623 'smbpasswd -a -i GLASS'. You may need to create a UNIX
1624 account for GLASS$ prior to this step (depending on your
1625 local configuration).
1626 2) connect the trust from a WINDOWS DC using "User Manager
1629 Now join winbindd on the Samba PDC to the SAMBA domain using
1630 the normal steps for adding a Samba server to an NT4 domain:
1631 (note that smbd & nmbd must be running at this point)
1633 root# net rpc join -U root
1634 Password: <enter root password from smbpasswd file here>
1636 Start winbindd and test the join with 'wbinfo -t'.
1638 Now test the trust relationship by connecting to the SAMBA DC
1639 (e.g. POGO) as a user from the WINDOWS domain:
1641 $ smbclient //pogo/netlogon -U Administrator -W WINDOWS
1644 Now connect to the WINDOWS DC (e.g. CRYSTAL) as a Samba user:
1646 $ smbclient //crystal/netlogon -U root -W WINDOWS
1649 ######################################################################
1653 Beginning with Samba3.0.0beta3, winbindd has been given new account
1654 manage functionality equivalent to the 'add user script' family of
1655 smb.conf parameters. The idmap design has also been changed to
1656 centralize control of foreign SID lookups and matching to UNIX
1660 Brief Description of Changes
1661 ----------------------------
1663 1) The sid_to_uid() family of functions (smbd/uid.c) have been
1664 reverted to the 2.2.x design. This means that when resolving a
1665 SID to a UID or similar mapping:
1667 a) First consult winbindd
1668 b) perform a local lookup only if winbindd fails to
1669 return a successful answer
1671 There are some variations to this, but these two rules generally
1674 2) All idmap lookups have been moved into winbindd. This means that
1675 a server must run winbindd (and support NSS) in order to achieve
1676 any mappings of SID to dynamically allocated UNIX ids. This was
1677 a conscious design choice.
1679 3) New functions have been added to winbindd to emulate the 'add user
1680 script' family of smbd functions without requiring that external
1681 scripts be defined. This functionality is controlled by the 'winbind
1682 enable local accounts' smb.conf parameter (enabled by default).
1684 However, this account management functionality is only supported
1685 in a local tdb (winbindd_idmap.tdb). If these new UNIX accounts
1686 must be shared among multiple Samba servers (such as a PDC and BDCs),
1687 it will be necessary to define your own 'add user script', et. al.
1688 programs that place the accounts/groups in some form of directory
1689 such as NIS or LDAP. This requirement was deemed beyond the scope
1690 of winbind's account management functions. Solutions for
1691 distributing UNIX system information have been deployed and tested
1692 for many years. We saw no need to reinvent the wheel.
1694 4) A member of a Samba controlled domain running winbindd is now able
1695 to map domain users directly onto existing UNIX accounts while still
1696 automatically creating accounts for trusted users and groups. This
1697 behavior is controlled by the 'winbind trusted domains only' smb.conf
1698 parameter (disabled by default to provide 2.2.x winbind behavior).
1700 5) Group mapping support is wrapped in the local_XX_to_XX() functions
1701 in smbd/uid.c. The reason that group mappings are not included
1702 in winbindd is because the purpose of Samba's group map is to
1703 match any Windows SID with an existing UNIX group. These UNIX
1704 groups can be created by winbindd (see next section), but the
1705 SID<->gid mapping is retreived by smbd, not winbindd.
1711 * security = server running winbindd to allocate accounts on demand
1713 * Samba PDC running winbindd to handle the automatic creation of UNIX
1714 identities for machine trust accounts
1716 * Automtically creating UNIX user and groups when migrating a Windows NT
1717 4.0 PDC to a Samba PDC. Winbindd must be running when executing
1718 'net rpc vampire' for this to work.
