234 Release Notes for Samba 3.0.2a
236 ==============================
238 Samba 3.0.2a is a minor patch release for the 3.0.2 code base
239 to address, in particular, a problem when using pdbedit to
240 sanitize (--force-initialized-passwords) Samba's tdbsam
241 backend. This is the latest stable release of Samba. This
242 is the version that all production Samba servers should be
243 running for all current bug-fixes.
245 ******************* Attention! Achtung! Kree! *********************
247 Beginning with Samba 3.0.2, passwords for accounts with a last
248 change time (LCT-XXX in smbpasswd, sambaPwdLastSet attribute in
249 ldapsam, etc...) of zero (0) will be regarded as uninitialized
250 strings. This will cause authentication to fail for such
251 accounts. If you have valid passwords that meet this criteria,
252 you must update the last change time to a non-zero value. If you
253 do not, then 'pdbedit --force-initialized-passwords' will disable
254 these accounts and reset the password hashes to a string of X's.
256 ******************* Attention! Achtung! Kree! *********************
259 ######################################################################
269 Please refer to the CVS log for the SAMBA_3_0 branch for complete
270 details. The list of changes per contributor are as follows:
273 o Jeremy Allison <jra@samba.org>
274 * Added paranoia checks in parsing code.
277 o Andrew Bartlet <abartlet@samba.org>
278 * Ensure that changes to uninitialized passwords in ldapsam
279 are written to the DIT.
282 o Gerald (Jerry) Carter <jerry@samba.org>
283 * Fixed iterator in tdbsam.
284 * Fix bug that disabled accounts with a valid NT password
285 hash, but no LanMan hash.
288 o Steve French <sfrench@us.ibm.com>
289 * Added missing nosetuid and noexec options.
292 o Bostjan Golob <golob@gimb.org>
293 * BUG 1046: Don't overwrite usernames of entries returned
297 o Sebastian Krahmer <krahmer@suse.de>
298 * Fixed potential crash bug in NTLMSSP parsing code.
301 o Tim Potter <tpot@samba.org>
302 * Fixed logic in tdb_brlock error checking.
305 o Urban Widmark <urban@teststation.com>
306 * Set nosuid,nodev flags in smbmnt by default.

311 =============================
312 Release Notes for Samba 3.0.2
314 =============================
316 It has been confirmed that previous versions of Samba 3.0 are
317 susceptible to a password initialization bug that could grant an
318 attacker unauthorized access to a user account created by the
319 mksmbpasswd.sh shell script.
321 The Common Vulnerabilities and Exposures project (cve.mitre.org)
322 has assigned the name CAN-2004-0082 to this issue.
324 Samba administrators not wishing to upgrade to the current
325 version should download the 3.0.2 release, build the pdbedit
328 root# pdbedit-3.0.2 --force-initialized-passwords
330 This will disable all accounts not possessing a valid password
331 (e.g. the password field has been set a string of X's).
333 Samba servers running 3.0.2 are not vulnerable to this bug
334 regardless of whether or not pdbedit has been used to sanitize
337 Some of the more visible bugs in 3.0.1 addressed in the 3.0.2
340 o Joining a Samba domain from Pre-SP2 Windows 2000 clients.
341 o Logging onto a Samba domain from Windows XP clients.
342 o Problems with the %U and %u smb.conf variables in relation to
343 Windows 9x/ME clients.
344 o Kerberos failures due to an invalid in memory keytab detection
346 o Updates to the ntlm_auth tool.
347 o Fixes for various SMB signing errors.
348 o Better separation of WINS and DNS queries for domain controllers.
349 o Issues with nss_winbind FreeBSD and Solaris.
350 o Several crash bugs in smbd and winbindd.
351 o Output formatting fixes for smbclient for better compatibility
352 with scripts based on the 2.2 version.

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

822 o Relax check on the pipe name in a dce/rpc bind response to work
823 around issues with establishing trusts to a Windows 2003 domain.
824 o Ensure we mangle names ending in '.' in hash2 mangling method.
825 o Correct parsing issues with munged dial string.
826 o Fix bugs in quota support for XFS.

828 name->SID mappings to do this via NSS rather than having to
829 know the winbindd pipe protocol.
830 o Adds a variant of the winbindd_getgroups() call called
831 winbindd_getusersids() that provides direct SID->SIDs listing of
832 a users supplementary groups. This is enough to allow non-Samba
833 applications to do ACL checking.
834 o Make sure we don't append the 'ldap suffix' when writing out the
835 'ldap XXX suffix' values in SWAT (bug 328).
836 o Fix renames across file systems.

924 The original 3.0.0 release notes follow
925 =======================================
926 WHATS NEW IN Samba 3.0.0
928 =======================================
934 1) Active Directory support. Samba 3.0 is now able to
935 join a ADS realm as a member server and authenticate
936 users using LDAP/Kerberos.
938 2) Unicode support. Samba will now negotiate UNICODE on the wire
939 and internally there is now a much better infrastructure for
940 multi-byte and UNICODE character sets.
942 3) New authentication system. The internal authentication system
943 has been almost completely rewritten. Most of the changes are
944 internal, but the new auth system is also very configurable.
946 4) New default filename mangling system.
948 5) A new "net" command has been added. It is somewhat similar to
949 the "net" command in windows. Eventually we plan to replace
950 numerous other utilities (such as smbpasswd) with subcommands
953 6) Samba now negotiates NT-style status32 codes on the wire. This
954 improves error handling a lot.
956 7) Better Windows 2000/XP/2003 printing support including publishing
957 printer attributes in active directory.
959 8) New loadable module support for passdb backends and character
962 9) New default dual-daemon winbindd support for better performance.
964 10) Support for migrating from a Windows NT 4.0 domain to a Samba
965 domain and maintaining user, group and domain SIDs.
967 11) Support for establishing trust relationships with Windows NT 4.0
970 12) Initial support for a distributed Winbind architecture using
971 an LDAP directory for storing SID to uid/gid mappings.
973 13) Major updates to the Samba documentation tree.
975 14) Full support for client and server SMB signing to ensure
976 compatibility with default Windows 2003 security settings.
978 15) Improvement of ACL mapping features based on code donated by
982 Plus lots of other improvements!
985 Additional Documentation
986 ------------------------
988 Please refer to Samba documentation tree (included in the docs/
989 subdirectory) for extensive explanations of installing, configuring
990 and maintaining Samba 3.0 servers and clients. It is advised to
991 begin with the Samba-HOWTO-Collection for overviews and specific
992 tasks (the current book is up to approximately 400 pages) and to
993 refer to the various man pages for information on individual options.
995 We are very glad to be able to include the second edition of
996 "Using Samba" by Jay Ts, Robert Eckstein, and David Collier-Brown
997 (O'Reilly & Associates) in this release. The book is available
998 on-line at http://samba.org/samba/docs/ and is included with
999 the Samba Web Administration Tool (SWAT). Thanks to the authors and
1000 publisher for making "Using Samba" under the GNU Free Documentation
1004 ######################################################################
1005 Upgrading from a previous Samba 3.0 beta
1006 ########################################
1008 Beginning with Samba 3.0.0beta3, the RID allocation functions
1009 have been moved into winbindd. Previously these were handled
1010 by each passdb backend. This means that winbindd must be running
1011 to automatically allocate RIDs for users and/or groups. Otherwise,
1012 smbd will use the 2.2 algorithm for generating new RIDs.
1014 If you are using 'passdb backend = tdbsam' with a previous Samba
1015 3.0 beta release (or possibly alpha), it may be necessary to
1016 move the RID_COUNTER entry from /usr/local/samba/private/passdb.tdb
1017 to winbindd_idmap.tdb. To do this:
1019 1) Ensure that winbindd_idmap.tdb exists (launch winbindd at least
1021 2) build tdbtool by executing 'make tdbtool' in the source/tdb/
1023 3) run: (note that 'tdb>' is the tool's prompt for input)
1025 root# ./tdbtool /usr/local/samba/private/passdb.tdb
1026 tdb> show RID_COUNTER
1030 [000] 0A 52 00 00 .R.
1032 tdb> move RID_COUNTER /usr/local/samba/var/locks/winbindd_idmap.tdb
1036 If you are using 'passdb backend = ldapsam', it will be necessary to
1037 store idmap entries in the LDAP directory as well (i.e. idmap backend
1038 = ldap). Refer to the 'net idmap' command for more information on
1039 migrating SID<->UNIX id mappings from one backend to another.
1041 If the RID_COUNTER record does not exist, then these instructions are
1042 unneccessary and the new RID_COUNTER record will be correctly generated

1222 This section contains brief descriptions of any new databases
1223 introduced in Samba 3.0. Please remember to backup your existing
1224 ${lock directory}/*tdb before upgrading to Samba 3.0. Samba will
1225 upgrade databases as they are opened (if necessary), but downgrading
1226 from 3.0 to 2.2 is an unsupported path.
1228 Name Description Backup?
1229 ---- ----------- -------
1230 account_policy User policy settings yes
1231 gencache Generic caching db no
1232 group_mapping Mapping table from Windows yes
1233 groups/SID to unix groups
1234 winbindd_idmap ID map table from SIDS to UNIX yes
1236 namecache Name resolution cache entries no
1237 netsamlogon_cache Cache of NET_USER_INFO_3 structure no
1238 returned as part of a successful
1239 net_sam_logon request
1240 printing/*.tdb Cached output from 'lpq no
1241 command' created on a per print
1243 registry Read-only samba registry skeleton no
1244 that provides support for exporting
1245 various db tables via the winreg RPCs
1251 The following issues are known changes in behavior between Samba 2.2 and
1252 Samba 3.0 that may affect certain installations of Samba.
1254 1) When operating as a member of a Windows domain, Samba 2.2 would
1255 map any users authenticated by the remote DC to the 'guest account'
1256 if a uid could not be obtained via the getpwnam() call. Samba 3.0
1257 rejects the connection as NT_STATUS_LOGON_FAILURE. There is no
1258 current work around to re-establish the 2.2 behavior.
1260 2) When adding machines to a Samba 2.2 controlled domain, the
1261 'add user script' was used to create the UNIX identity of the
1262 machine trust account. Samba 3.0 introduces a new 'add machine
1263 script' that must be specified for this purpose. Samba 3.0 will
1264 not fall back to using the 'add user script' in the absence of
1265 an 'add machine script'
1268 ######################################################################
1269 Passdb Backends and Authentication
1270 ##################################
1272 There have been a few new changes that Samba administrators should be
1273 aware of when moving to Samba 3.0.
1275 1) encrypted passwords have been enabled by default in order to
1276 inter-operate better with out-of-the-box Windows client
1277 installations. This does mean that either (a) a samba account
1278 must be created for each user, or (b) 'encrypt passwords = no'
1279 must be explicitly defined in smb.conf.
1281 2) Inclusion of new 'security = ads' option for integration
1282 with an Active Directory domain using the native Windows
1283 Kerberos 5 and LDAP protocols.
1285 MIT kerberos 1.3.1 supports the ARCFOUR-HMAC-MD5 encryption
1286 type which is neccessary for servers on which the
1287 administrator password has not been changed, or kerberos-enabled
1288 SMB connections to servers that require Kerberos SMB signing.
1289 Besides this one difference, either MIT or Heimdal Kerberos
1290 distributions are usable by Samba 3.0.
1293 Samba 3.0 also includes the possibility of setting up chains
1294 of authentication methods (auth methods) and account storage
1295 backends (passdb backend). Please refer to the smb.conf(5)
1296 man page for details. While both parameters assume sane default
1297 values, it is likely that you will need to understand what the
1298 values actually mean in order to ensure Samba operates correctly.
1300 The recommended passdb backends at this time are
1302 * smbpasswd - 2.2 compatible flat file format
1303 * tdbsam - attribute rich database intended as an smbpasswd
1304 replacement for stand alone servers
1305 * ldapsam - attribute rich account storage and retrieval
1306 backend utilizing an LDAP directory.
1307 * ldapsam_compat - a 2.2 backward compatible LDAP account
1310 Certain functions of the smbpasswd(8) tool have been split between the
1311 new smbpasswd(8) utility, the net(8) tool, and the new pdbedit(8)
1312 utility. See the respective man pages for details.
1315 ######################################################################
1319 This section outlines the new features affecting Samba / LDAP
1325 A new object class (sambaSamAccount) has been introduced to replace
1326 the old sambaAccount. This change aids us in the renaming of
1327 attributes to prevent clashes with attributes from other vendors.
1328 There is a conversion script (examples/LDAP/convertSambaAccount) to
1329 modify and LDIF file to the new schema.
1333 $ ldapsearch .... -b "ou=people,dc=..." > sambaAcct.ldif
1334 $ convertSambaAccount --sid=<Domain SID> \
1335 --input=sambaAcct.ldif --output=sambaSamAcct.ldif \
1336 --changetype=[modify|add]
1338 The <DOM SID> can be obtained by running 'net getlocalsid
1339 <DOMAINNAME>' on the Samba PDC as root. The changetype determines
1340 the format of the generated LDIF output--either create new entries
1341 or modify existing entries.
1343 The old sambaAccount schema may still be used by specifying the
1344 "ldapsam_compat" passdb backend. However, the sambaAccount and
1345 associated attributes have been moved to the historical section of
1346 the schema file and must be uncommented before use if needed.
1347 The 2.2 object class declaration for a sambaAccount has not changed
1348 in the 3.0 samba.schema file.
1350 Other new object classes and their uses include:
1352 * sambaDomain - domain information used to allocate rids
1353 for users and groups as necessary. The attributes are added
1354 in 'ldap suffix' directory entry automatically if
1355 an idmap uid/gid range has been set and the 'ldapsam'
1356 passdb backend has been selected.
1358 * sambaGroupMapping - an object representing the
1359 relationship between a posixGroup and a Windows
1360 group/SID. These entries are stored in the 'ldap
1361 group suffix' and managed by the 'net groupmap' command.
1363 * sambaUnixIdPool - created in the 'ldap idmap suffix' entry
1364 automatically and contains the next available 'idmap uid' and
1367 * sambaIdmapEntry - object storing a mapping between a
1368 SID and a UNIX uid/gid. These objects are created by the
1369 idmap_ldap module as needed.
1371 * sambaSidEntry - object representing a SID alone, as a Structural
1372 class on which to build the sambaIdmapEntry.
1375 New Suffix for Searching
1376 ------------------------
1378 The following new smb.conf parameters have been added to aid in directing
1379 certain LDAP queries when 'passdb backend = ldapsam://...' has been
1382 * ldap suffix - used to search for user and computer accounts
1383 * ldap user suffix - used to store user accounts
1384 * ldap machine suffix - used to store machine trust accounts
1385 * ldap group suffix - location of posixGroup/sambaGroupMapping entries
1386 * ldap idmap suffix - location of sambaIdmapEntry objects
1388 If an 'ldap suffix' is defined, it will be appended to all of the
1389 remaining sub-suffix parameters. In this case, the order of the suffix
1390 listings in smb.conf is important. Always place the 'ldap suffix' first
1393 Due to a limitation in Samba's smb.conf parsing, you should not surround
1394 the DN's with quotation marks.
1400 Samba 3.0 supports an ldap backend for the idmap subsystem. The
1401 following options would inform Samba that the idmap table should be
1402 stored on the directory server onterose in the "ou=idmap,dc=plainjoe,
1407 idmap backend = ldap:ldap://onterose/
1408 ldap idmap suffix = ou=idmap,dc=plainjoe,dc=org
1409 idmap uid = 40000-50000
1410 idmap gid = 40000-50000
1412 This configuration allows winbind installations on multiple servers to
1413 share a uid/gid number space, thus avoiding the interoperability problems
1414 with NFS that were present in Samba 2.2.

1419 Trust Relationships and a Samba Domain
1420 ######################################
1422 Samba 3.0.0beta2 is able to utilize winbindd as the means of
1423 allocating uids and gids to trusted users and groups. More
1424 information regarding Samba's support for establishing trust
1425 relationships can be found in the Samba-HOWTO-Collection included
1426 in the docs/ directory of this release.
1428 First create your Samba PDC and ensure that everything is
1429 working correctly before moving on the trusts.
1431 To establish Samba as the trusting domain (named SAMBA) from a Windows NT
1432 4.0 domain named WINDOWS:
1434 1) create the trust account for SAMBA in "User Manager for Domains"
1435 2) connect the trust from the Samba domain using
1436 'net rpc trustdom establish GLASS'
1438 To create a trustlationship with SAMBA as the trusted domain:
1440 1) create the initial trust account for GLASS using
1441 'smbpasswd -a -i GLASS'. You may need to create a UNIX
1442 account for GLASS$ prior to this step (depending on your
1443 local configuration).
1444 2) connect the trust from a WINDOWS DC using "User Manager
1447 Now join winbindd on the Samba PDC to the SAMBA domain using
1448 the normal steps for adding a Samba server to an NT4 domain:
1449 (note that smbd & nmbd must be running at this point)
1451 root# net rpc join -U root
1452 Password: <enter root password from smbpasswd file here>
1454 Start winbindd and test the join with 'wbinfo -t'.
1456 Now test the trust relationship by connecting to the SAMBA DC
1457 (e.g. POGO) as a user from the WINDOWS domain:
1459 $ smbclient //pogo/netlogon -U Administrator -W WINDOWS
1462 Now connect to the WINDOWS DC (e.g. CRYSTAL) as a Samba user:
1464 $ smbclient //crystal/netlogon -U root -W WINDOWS
1467 ######################################################################
1471 Beginning with Samba3.0.0beta3, winbindd has been given new account
1472 manage functionality equivalent to the 'add user script' family of
1473 smb.conf parameters. The idmap design has also been changed to
1474 centralize control of foreign SID lookups and matching to UNIX
1478 Brief Description of Changes
1479 ----------------------------
1481 1) The sid_to_uid() family of functions (smbd/uid.c) have been
1482 reverted to the 2.2.x design. This means that when resolving a
1483 SID to a UID or similar mapping:
1485 a) First consult winbindd
1486 b) perform a local lookup only if winbindd fails to
1487 return a successful answer
1489 There are some variations to this, but these two rules generally
1492 2) All idmap lookups have been moved into winbindd. This means that
1493 a server must run winbindd (and support NSS) in order to achieve
1494 any mappings of SID to dynamically allocated UNIX ids. This was
1495 a conscious design choice.
1497 3) New functions have been added to winbindd to emulate the 'add user
1498 script' family of smbd functions without requiring that external
1499 scripts be defined. This functionality is controlled by the 'winbind
1500 enable local accounts' smb.conf parameter (enabled by default).
1502 However, this account management functionality is only supported
1503 in a local tdb (winbindd_idmap.tdb). If these new UNIX accounts
1504 must be shared among multiple Samba servers (such as a PDC and BDCs),
1505 it will be necessary to define your own 'add user script', et. al.
1506 programs that place the accounts/groups in some form of directory
1507 such as NIS or LDAP. This requirement was deemed beyond the scope
1508 of winbind's account management functions. Solutions for
1509 distributing UNIX system information have been deployed and tested
1510 for many years. We saw no need to reinvent the wheel.
1512 4) A member of a Samba controlled domain running winbindd is now able
1513 to map domain users directly onto existing UNIX accounts while still
1514 automatically creating accounts for trusted users and groups. This
1515 behavior is controlled by the 'winbind trusted domains only' smb.conf
1516 parameter (disabled by default to provide 2.2.x winbind behavior).
1518 5) Group mapping support is wrapped in the local_XX_to_XX() functions
1519 in smbd/uid.c. The reason that group mappings are not included
1520 in winbindd is because the purpose of Samba's group map is to
1521 match any Windows SID with an existing UNIX group. These UNIX
1522 groups can be created by winbindd (see next section), but the
1523 SID<->gid mapping is retreived by smbd, not winbindd.
1529 * security = server running winbindd to allocate accounts on demand
1531 * Samba PDC running winbindd to handle the automatic creation of UNIX
1532 identities for machine trust accounts
1534 * Automtically creating UNIX user and groups when migrating a Windows NT
1535 4.0 PDC to a Samba PDC. Winbindd must be running when executing
1536 'net rpc vampire' for this to work.
