503 Release Notes for Samba 3.0.2a
505 ==============================
507 Samba 3.0.2a is a minor patch release for the 3.0.2 code base
508 to address, in particular, a problem when using pdbedit to
509 sanitize (--force-initialized-passwords) Samba's tdbsam
510 backend. This is the latest stable release of Samba. This
511 is the version that all production Samba servers should be
512 running for all current bug-fixes.
514 ******************* Attention! Achtung! Kree! *********************
516 Beginning with Samba 3.0.2, passwords for accounts with a last
517 change time (LCT-XXX in smbpasswd, sambaPwdLastSet attribute in
518 ldapsam, etc...) of zero (0) will be regarded as uninitialized
519 strings. This will cause authentication to fail for such
520 accounts. If you have valid passwords that meet this criteria,
521 you must update the last change time to a non-zero value. If you
522 do not, then 'pdbedit --force-initialized-passwords' will disable
523 these accounts and reset the password hashes to a string of X's.
525 ******************* Attention! Achtung! Kree! *********************
534 Please refer to the CVS log for the SAMBA_3_0 branch for complete
535 details. The list of changes per contributor are as follows:
538 o Jeremy Allison <jra@samba.org>
539 * Added paranoia checks in parsing code.
542 o Andrew Bartlet <abartlet@samba.org>
543 * Ensure that changes to uninitialized passwords in ldapsam
544 are written to the DIT.
547 o Gerald (Jerry) Carter <jerry@samba.org>
548 * Fixed iterator in tdbsam.
549 * Fix bug that disabled accounts with a valid NT password
550 hash, but no LanMan hash.
553 o Steve French <sfrench@us.ibm.com>
554 * Added missing nosetuid and noexec options.
557 o Bostjan Golob <golob@gimb.org>
558 * BUG 1046: Don't overwrite usernames of entries returned
562 o Sebastian Krahmer <krahmer@suse.de>
563 * Fixed potential crash bug in NTLMSSP parsing code.
566 o Tim Potter <tpot@samba.org>
567 * Fixed logic in tdb_brlock error checking.
570 o Urban Widmark <urban@teststation.com>
571 * Set nosuid,nodev flags in smbmnt by default.

576 =============================
577 Release Notes for Samba 3.0.2
579 =============================
581 It has been confirmed that previous versions of Samba 3.0 are
582 susceptible to a password initialization bug that could grant an
583 attacker unauthorized access to a user account created by the
584 mksmbpasswd.sh shell script.
586 The Common Vulnerabilities and Exposures project (cve.mitre.org)
587 has assigned the name CAN-2004-0082 to this issue.
589 Samba administrators not wishing to upgrade to the current
590 version should download the 3.0.2 release, build the pdbedit
593 root# pdbedit-3.0.2 --force-initialized-passwords
595 This will disable all accounts not possessing a valid password
596 (e.g. the password field has been set a string of X's).
598 Samba servers running 3.0.2 are not vulnerable to this bug
599 regardless of whether or not pdbedit has been used to sanitize
602 Some of the more visible bugs in 3.0.1 addressed in the 3.0.2
605 o Joining a Samba domain from Pre-SP2 Windows 2000 clients.
606 o Logging onto a Samba domain from Windows XP clients.
607 o Problems with the %U and %u smb.conf variables in relation to
608 Windows 9x/ME clients.
609 o Kerberos failures due to an invalid in memory keytab detection
611 o Updates to the ntlm_auth tool.
612 o Fixes for various SMB signing errors.
613 o Better separation of WINS and DNS queries for domain controllers.
614 o Issues with nss_winbind FreeBSD and Solaris.
615 o Several crash bugs in smbd and winbindd.
616 o Output formatting fixes for smbclient for better compatibility
617 with scripts based on the 2.2 version.

1189 The original 3.0.0 release notes follow
1190 =======================================
1191 WHATS NEW IN Samba 3.0.0
1193 =======================================
1199 1) Active Directory support. Samba 3.0 is now able to
1200 join a ADS realm as a member server and authenticate
1201 users using LDAP/Kerberos.
1203 2) Unicode support. Samba will now negotiate UNICODE on the wire
1204 and internally there is now a much better infrastructure for
1205 multi-byte and UNICODE character sets.
1207 3) New authentication system. The internal authentication system
1208 has been almost completely rewritten. Most of the changes are
1209 internal, but the new auth system is also very configurable.
1211 4) New default filename mangling system.
1213 5) A new "net" command has been added. It is somewhat similar to
1214 the "net" command in windows. Eventually we plan to replace
1215 numerous other utilities (such as smbpasswd) with subcommands
1218 6) Samba now negotiates NT-style status32 codes on the wire. This
1219 improves error handling a lot.
1221 7) Better Windows 2000/XP/2003 printing support including publishing
1222 printer attributes in active directory.
1224 8) New loadable module support for passdb backends and character
1227 9) New default dual-daemon winbindd support for better performance.
1229 10) Support for migrating from a Windows NT 4.0 domain to a Samba
1230 domain and maintaining user, group and domain SIDs.
1232 11) Support for establishing trust relationships with Windows NT 4.0
1235 12) Initial support for a distributed Winbind architecture using
1236 an LDAP directory for storing SID to uid/gid mappings.
1238 13) Major updates to the Samba documentation tree.
1240 14) Full support for client and server SMB signing to ensure
1241 compatibility with default Windows 2003 security settings.
1243 15) Improvement of ACL mapping features based on code donated by
1244 Andreas Grünbacher.
1247 Plus lots of other improvements!
1250 Additional Documentation
1251 ------------------------
1253 Please refer to Samba documentation tree (included in the docs/
1254 subdirectory) for extensive explanations of installing, configuring
1255 and maintaining Samba 3.0 servers and clients. It is advised to
1256 begin with the Samba-HOWTO-Collection for overviews and specific
1257 tasks (the current book is up to approximately 400 pages) and to
1258 refer to the various man pages for information on individual options.
1260 We are very glad to be able to include the second edition of
1261 "Using Samba" by Jay Ts, Robert Eckstein, and David Collier-Brown
1262 (O'Reilly & Associates) in this release. The book is available
1263 on-line at http://samba.org/samba/docs/ and is included with
1264 the Samba Web Administration Tool (SWAT). Thanks to the authors and
1265 publisher for making "Using Samba" under the GNU Free Documentation

1270 Upgrading from a previous Samba 3.0 beta
1271 ########################################
1273 Beginning with Samba 3.0.0beta3, the RID allocation functions
1274 have been moved into winbindd. Previously these were handled
1275 by each passdb backend. This means that winbindd must be running
1276 to automatically allocate RIDs for users and/or groups. Otherwise,
1277 smbd will use the 2.2 algorithm for generating new RIDs.
1279 If you are using 'passdb backend = tdbsam' with a previous Samba
1280 3.0 beta release (or possibly alpha), it may be necessary to
1281 move the RID_COUNTER entry from /usr/local/samba/private/passdb.tdb
1282 to winbindd_idmap.tdb. To do this:
1284 1) Ensure that winbindd_idmap.tdb exists (launch winbindd at least
1286 2) build tdbtool by executing 'make tdbtool' in the source/tdb/
1288 3) run: (note that 'tdb>' is the tool's prompt for input)
1290 root# ./tdbtool /usr/local/samba/private/passdb.tdb
1291 tdb> show RID_COUNTER
1295 [000] 0A 52 00 00 .R.
1297 tdb> move RID_COUNTER /usr/local/samba/var/locks/winbindd_idmap.tdb
1301 If you are using 'passdb backend = ldapsam', it will be necessary to
1302 store idmap entries in the LDAP directory as well (i.e. idmap backend
1303 = ldap). Refer to the 'net idmap' command for more information on
1304 migrating SID<->UNIX id mappings from one backend to another.
1306 If the RID_COUNTER record does not exist, then these instructions are
1307 unneccessary and the new RID_COUNTER record will be correctly generated

1487 This section contains brief descriptions of any new databases
1488 introduced in Samba 3.0. Please remember to backup your existing
1489 ${lock directory}/*tdb before upgrading to Samba 3.0. Samba will
1490 upgrade databases as they are opened (if necessary), but downgrading
1491 from 3.0 to 2.2 is an unsupported path.
1493 Name Description Backup?
1494 ---- ----------- -------
1495 account_policy User policy settings yes
1496 gencache Generic caching db no
1497 group_mapping Mapping table from Windows yes
1498 groups/SID to unix groups
1499 winbindd_idmap ID map table from SIDS to UNIX yes
1501 namecache Name resolution cache entries no

1506 command' created on a per print
1508 registry Read-only samba registry skeleton no
1509 that provides support for exporting
1510 various db tables via the winreg RPCs
1516 The following issues are known changes in behavior between Samba 2.2 and
1517 Samba 3.0 that may affect certain installations of Samba.
1519 1) When operating as a member of a Windows domain, Samba 2.2 would
1520 map any users authenticated by the remote DC to the 'guest account'
1521 if a uid could not be obtained via the getpwnam() call. Samba 3.0
1522 rejects the connection as NT_STATUS_LOGON_FAILURE. There is no
1523 current work around to re-establish the 2.2 behavior.
1525 2) When adding machines to a Samba 2.2 controlled domain, the
1526 'add user script' was used to create the UNIX identity of the
1527 machine trust account. Samba 3.0 introduces a new 'add machine
1528 script' that must be specified for this purpose. Samba 3.0 will
1529 not fall back to using the 'add user script' in the absence of
1530 an 'add machine script'
1533 ######################################################################
1534 Passdb Backends and Authentication
1535 ##################################
1537 There have been a few new changes that Samba administrators should be
1538 aware of when moving to Samba 3.0.
1540 1) encrypted passwords have been enabled by default in order to
1541 inter-operate better with out-of-the-box Windows client
1542 installations. This does mean that either (a) a samba account
1543 must be created for each user, or (b) 'encrypt passwords = no'
1544 must be explicitly defined in smb.conf.
1546 2) Inclusion of new 'security = ads' option for integration
1547 with an Active Directory domain using the native Windows
1548 Kerberos 5 and LDAP protocols.
1550 MIT kerberos 1.3.1 supports the ARCFOUR-HMAC-MD5 encryption
1551 type which is neccessary for servers on which the
1552 administrator password has not been changed, or kerberos-enabled
1553 SMB connections to servers that require Kerberos SMB signing.
1554 Besides this one difference, either MIT or Heimdal Kerberos
1555 distributions are usable by Samba 3.0.
1558 Samba 3.0 also includes the possibility of setting up chains
1559 of authentication methods (auth methods) and account storage
1560 backends (passdb backend). Please refer to the smb.conf(5)
1561 man page for details. While both parameters assume sane default
1562 values, it is likely that you will need to understand what the
1563 values actually mean in order to ensure Samba operates correctly.
1565 The recommended passdb backends at this time are
1567 * smbpasswd - 2.2 compatible flat file format
1568 * tdbsam - attribute rich database intended as an smbpasswd
1569 replacement for stand alone servers
1570 * ldapsam - attribute rich account storage and retrieval
1571 backend utilizing an LDAP directory.
1572 * ldapsam_compat - a 2.2 backward compatible LDAP account
1575 Certain functions of the smbpasswd(8) tool have been split between the
1576 new smbpasswd(8) utility, the net(8) tool, and the new pdbedit(8)
1577 utility. See the respective man pages for details.
1580 ######################################################################
1584 This section outlines the new features affecting Samba / LDAP
1590 A new object class (sambaSamAccount) has been introduced to replace
1591 the old sambaAccount. This change aids us in the renaming of
1592 attributes to prevent clashes with attributes from other vendors.
1593 There is a conversion script (examples/LDAP/convertSambaAccount) to
1594 modify and LDIF file to the new schema.
1598 $ ldapsearch .... -b "ou=people,dc=..." > sambaAcct.ldif
1599 $ convertSambaAccount --sid=<Domain SID> \
1600 --input=sambaAcct.ldif --output=sambaSamAcct.ldif \
1601 --changetype=[modify|add]
1603 The <DOM SID> can be obtained by running 'net getlocalsid
1604 <DOMAINNAME>' on the Samba PDC as root. The changetype determines
1605 the format of the generated LDIF output--either create new entries
1606 or modify existing entries.
1608 The old sambaAccount schema may still be used by specifying the
1609 "ldapsam_compat" passdb backend. However, the sambaAccount and
1610 associated attributes have been moved to the historical section of
1611 the schema file and must be uncommented before use if needed.
1612 The 2.2 object class declaration for a sambaAccount has not changed
1613 in the 3.0 samba.schema file.
1615 Other new object classes and their uses include:
1617 * sambaDomain - domain information used to allocate rids
1618 for users and groups as necessary. The attributes are added
1619 in 'ldap suffix' directory entry automatically if
1620 an idmap uid/gid range has been set and the 'ldapsam'
1621 passdb backend has been selected.
1623 * sambaGroupMapping - an object representing the
1624 relationship between a posixGroup and a Windows
1625 group/SID. These entries are stored in the 'ldap
1626 group suffix' and managed by the 'net groupmap' command.
1628 * sambaUnixIdPool - created in the 'ldap idmap suffix' entry
1629 automatically and contains the next available 'idmap uid' and
1632 * sambaIdmapEntry - object storing a mapping between a
1633 SID and a UNIX uid/gid. These objects are created by the
1634 idmap_ldap module as needed.
1636 * sambaSidEntry - object representing a SID alone, as a Structural
1637 class on which to build the sambaIdmapEntry.
1640 New Suffix for Searching
1641 ------------------------
1643 The following new smb.conf parameters have been added to aid in directing
1644 certain LDAP queries when 'passdb backend = ldapsam://...' has been
1647 * ldap suffix - used to search for user and computer accounts
1648 * ldap user suffix - used to store user accounts
1649 * ldap machine suffix - used to store machine trust accounts
1650 * ldap group suffix - location of posixGroup/sambaGroupMapping entries
1651 * ldap idmap suffix - location of sambaIdmapEntry objects
1653 If an 'ldap suffix' is defined, it will be appended to all of the
1654 remaining sub-suffix parameters. In this case, the order of the suffix
1655 listings in smb.conf is important. Always place the 'ldap suffix' first
1658 Due to a limitation in Samba's smb.conf parsing, you should not surround
1659 the DN's with quotation marks.
1665 Samba 3.0 supports an ldap backend for the idmap subsystem. The
1666 following options would inform Samba that the idmap table should be
1667 stored on the directory server onterose in the "ou=idmap,dc=plainjoe,
1672 idmap backend = ldap:ldap://onterose/
1673 ldap idmap suffix = ou=idmap,dc=plainjoe,dc=org
1674 idmap uid = 40000-50000
1675 idmap gid = 40000-50000
1677 This configuration allows winbind installations on multiple servers to
1678 share a uid/gid number space, thus avoiding the interoperability problems
1679 with NFS that were present in Samba 2.2.
1683 ######################################################################
1684 Trust Relationships and a Samba Domain
1685 ######################################
1687 Samba 3.0.0beta2 is able to utilize winbindd as the means of
1688 allocating uids and gids to trusted users and groups. More
1689 information regarding Samba's support for establishing trust
1690 relationships can be found in the Samba-HOWTO-Collection included
1691 in the docs/ directory of this release.
1693 First create your Samba PDC and ensure that everything is
1694 working correctly before moving on the trusts.
1696 To establish Samba as the trusting domain (named SAMBA) from a Windows NT
1697 4.0 domain named WINDOWS:
1699 1) create the trust account for SAMBA in "User Manager for Domains"
1700 2) connect the trust from the Samba domain using
1701 'net rpc trustdom establish GLASS'
1703 To create a trustlationship with SAMBA as the trusted domain:
1705 1) create the initial trust account for GLASS using
1706 'smbpasswd -a -i GLASS'. You may need to create a UNIX
1707 account for GLASS$ prior to this step (depending on your
1708 local configuration).
1709 2) connect the trust from a WINDOWS DC using "User Manager
1712 Now join winbindd on the Samba PDC to the SAMBA domain using
1713 the normal steps for adding a Samba server to an NT4 domain:
1714 (note that smbd & nmbd must be running at this point)
1716 root# net rpc join -U root
1717 Password: <enter root password from smbpasswd file here>
1719 Start winbindd and test the join with 'wbinfo -t'.
1721 Now test the trust relationship by connecting to the SAMBA DC
1722 (e.g. POGO) as a user from the WINDOWS domain:
1724 $ smbclient //pogo/netlogon -U Administrator -W WINDOWS
1727 Now connect to the WINDOWS DC (e.g. CRYSTAL) as a Samba user:
1729 $ smbclient //crystal/netlogon -U root -W WINDOWS
1732 ######################################################################
1736 Beginning with Samba3.0.0beta3, winbindd has been given new account
1737 manage functionality equivalent to the 'add user script' family of
1738 smb.conf parameters. The idmap design has also been changed to
1739 centralize control of foreign SID lookups and matching to UNIX
1743 Brief Description of Changes
1744 ----------------------------
1746 1) The sid_to_uid() family of functions (smbd/uid.c) have been
1747 reverted to the 2.2.x design. This means that when resolving a
1748 SID to a UID or similar mapping:
1750 a) First consult winbindd
1751 b) perform a local lookup only if winbindd fails to
1752 return a successful answer
1754 There are some variations to this, but these two rules generally
1757 2) All idmap lookups have been moved into winbindd. This means that
1758 a server must run winbindd (and support NSS) in order to achieve
1759 any mappings of SID to dynamically allocated UNIX ids. This was
1760 a conscious design choice.
1762 3) New functions have been added to winbindd to emulate the 'add user
1763 script' family of smbd functions without requiring that external
1764 scripts be defined. This functionality is controlled by the 'winbind
1765 enable local accounts' smb.conf parameter (enabled by default).
1767 However, this account management functionality is only supported
1768 in a local tdb (winbindd_idmap.tdb). If these new UNIX accounts
1769 must be shared among multiple Samba servers (such as a PDC and BDCs),
1770 it will be necessary to define your own 'add user script', et. al.
1771 programs that place the accounts/groups in some form of directory
1772 such as NIS or LDAP. This requirement was deemed beyond the scope
1773 of winbind's account management functions. Solutions for
1774 distributing UNIX system information have been deployed and tested
1775 for many years. We saw no need to reinvent the wheel.
1777 4) A member of a Samba controlled domain running winbindd is now able
1778 to map domain users directly onto existing UNIX accounts while still
1779 automatically creating accounts for trusted users and groups. This
1780 behavior is controlled by the 'winbind trusted domains only' smb.conf
1781 parameter (disabled by default to provide 2.2.x winbind behavior).
1783 5) Group mapping support is wrapped in the local_XX_to_XX() functions
1784 in smbd/uid.c. The reason that group mappings are not included
1785 in winbindd is because the purpose of Samba's group map is to
1786 match any Windows SID with an existing UNIX group. These UNIX
1787 groups can be created by winbindd (see next section), but the
1788 SID<->gid mapping is retreived by smbd, not winbindd.
1794 * security = server running winbindd to allocate accounts on demand
1796 * Samba PDC running winbindd to handle the automatic creation of UNIX
1797 identities for machine trust accounts
1799 * Automtically creating UNIX user and groups when migrating a Windows NT
1800 4.0 PDC to a Samba PDC. Winbindd must be running when executing
1801 'net rpc vampire' for this to work.
