2 Release Notes for Samba 3.0.8
3 Nov 7, 2004
4 =============================
6 This is the latest stable release of Samba. This is the version
7 that production Samba servers should be running for all
8 current bug-fixes. There have been several important issues
9 fixes since the 3.0.7 release. See the "Changes" section for
10 details on exact updates.
12 Common bugs fixed in 3.0.8 include:
14 o Compile fixes for HP-UX
15 o Fixes for the printer publishing code used when joined to
16 an AD domain.
17 o Incompatibilities with file system quotas.
18 o Several bugs in the spoolss printing code and print system
19 backends.
20 o Inconsistencies in the username map functionality when
21 configured on domain member servers.
22 o Various compile warnings and errors on various platforms.
23 o Fixes for kerberos interoperability with Windows 200x
24 domains when using DES keys.
25 o Fix for CAN-2004-0930 -- smbd remote DoS vulnerability.
28 New features included in the 3.0.8 release are:
30 o New migration functionality added the the net tool
31 for files/directories, printers, and shares.
32 o New experimental idmap backend for assigning uids/gids
33 directly based on the user/group RID when acting as a
34 member of single domain without any trusts.
35 o Additional printer migration support for XP/2003 platforms.
38 Change in Winbindd Behavior
39 ---------------------------
41 All usernames returned by winbindd are now converted to lower
42 case for better consistency. This means any winbind installation
43 relying on the winbind username will need to rename existing
44 directories and/or files based on the username (%u and %U) to lower
45 case (e.g. mv $name `echo $name | tr '[A-Z]' '[a-z]'`). This may
46 include mail spool files, home directories, valid user lines in
47 smb.conf, etc....
50 Change in Username Map
51 ----------------------
53 Previous Samba releases would only support reading the fully qualified
54 username (e.g. DOMAIN\user) from the username map when performing a
55 kerberos login from a client. However, when looking up a map
56 entry for a user authenticated by NTLM[SSP], only the login name would be
57 used for matches. This resulted in inconsistent behavior sometimes
58 even on the same server.
60 Samba 3.0.8 obeys the following rules when applying the username
61 map functionality:
63 * When performing local authentication, the username map is
64 applied to the login name before attempting to authenticate
65 the connection.
66 * When relying upon a external domain controller for validating
67 authentication requests, smbd will apply the username map
68 to the fully qualified username (i.e. DOMAIN\user) only
69 after the user has been successfully authenticated.

644 Release Notes for Samba 3.0.6
645 Aug 19, 2004
646 =============================
648 Common bugs fixed in 3.0.6 include:
650 o Schannel failure in winbindd.
651 o Numerous memory leaks.
652 o Incompatibilities between the 'write list' and 'force user'
653 smb.conf options.
654 o Premature optimization of the open_directory() internal
655 function that broke tools such as the ArcServe backup
656 agent, Macromedia HomeSite, and Robocopy.
657 o Corrupt workgroup names in nmbd's browse.dat.
658 o Sharing violation errors commonly seen when opening
659 when serving Microsoft Office documents from a Samba
660 file share.
661 o Browsing problems caused by an apostrophe (') in the
662 computer's description field.
663 o Problems creating special file types from UNIX CIFS
664 clients and enabling 'unix extensions'.
665 o Fix stalls in smbd caused by inaccessible LDAP servers.
666 o Remove various memory leaks.
667 o Fix issues in the password lockout feature.
669 New features introduced in this release include:
671 O Support symlinks created by CIFS clients which
672 can be followed on the server.
673 o Using a cups server other than localhost.
674 o Maintaining the service principal entry in the system
675 keytab for integration with other kerberized services.
676 Please refer to the 'use kerberos keytab' entry in
677 smb.conf(5). When using the heimdal kerberos libraries,
678 you must also specify the following in /etc/krb5.conf:
679 [libdefaults]
680 default_keytab_name = FILE:/etc/krb5.keytab
681 o Support for maintaining individual printer names
682 stored separately from the printer's sharename.
683 o Support for maintaining user password history.
684 o Support for honoring the logon times for user in a
685 Samba domain.
687 --------------------------------------------
688 unix extensions = yes (default) and symlinks
689 --------------------------------------------
691 Beginning with Samba 3.0.6pre1 (formerly known as 3.0.5pre1),
692 clients supporting the UNIX extensions to the CIFS protocol
693 can create symlinks to absolute paths which will be **followed**
694 by the server. This functionality has been requested in order
695 to correctly support certain applications when the user's home
696 directory is mounted using some type of CIFS client (e.g. the
697 cifsvfs in the Linux 2.6 kernel).
699 If this behavior is not acceptable for your production environment
700 you can set 'wide links = no' in the specific share declaration in
701 the server's smb.conf. Be aware that disabling wide link support
702 out of a share in Samba may impact the server's performance due
703 to the fact that smbd will now have to check each path additional
704 times before traversing it.
706 ------------------------
707 Password History Support
708 ------------------------
710 The new password history feature allows smbd to check the new
711 password in password change requests against a list of the user's
712 previous passwords. The number of previous passwords to save can
713 be set using pdbedit (4 in this example):
715 root# pdbedit -P "password history" -C 4
717 When using the ldapsam passdb backend, it is vital to secure the
718 following attributes from access by non-administrative users:
720 * sambaNTPassword
721 * sambaLMPassword
722 * sambaPasswordHistory
724 You should refer to your directory server's documentation on how
725 to implement this restriction.
728 Changes since 3.0.5

873 mmap' parameter).
874 * BUG 1221: revert old change that used single and double
875 quotes as delimeters in next_token(), and change
876 print_parameter() to print out parm values surrounded by
877 double quotes (instead of single quotes).
878 * Prevent home directories added during the SMBsesssetup&X from

922 enumprinters'.
923 * Reintroduce 'force unknown acl user' parameter. When getting a
924 security descriptor for a file, if the owner sid is not known,
925 the owner uid is set to the current uid. Same for group sid.
926 * Ensure that REG_SZ values in the SetPrinterData actually
927 get written in UNICODE strings rather than ASCII.
928 * Ensure that the last kerberos error return is not invalid.
929 * Display share ACL entries from rpcclient.

968 the NT security editor.
969 * Fix crash bug caused by trying to Base64 encode a NULL string.
970 * Fix DOS error code bug in reply_chkpath().
971 * Correct misunderstanding of the max_size field in

973 field with individual bits what to retrieve.
974 * Implement 'net rpc group rename' -- rename domain groups.
975 * Implement the 'cups server' option. This makes it possible
976 to have virtual smbd's connect to different cups daemons.
977 * Paranoia fixes when adding local aliases to a user's NT_TOKEN.

980 return.
981 * Make sure that the clients are given back the IP address to
982 which they connected in the case of a multi-homed host. Only
983 affects strings the spoolss printing replies.
984 * Fix the bad password lockout. This has not worked as pdb_ldap.c
985 did not ask for the modifyTimestamp attribute, so it could
986 not find it. Try not to regress by not putting that attrib
987 in the main list but append it manually for the relevant searches.
988 * Fix two memleaks in login_cache.c.
989 * fixes memory bloat when unmarshalling strings.
990 * Fix compile errors using gcc 3.2 on SuSE 8.2.

999 * Allow the 'idmap backend' parameter to accept a list of
1000 LDAP servers for failover purposes.
1001 * Revert code in smbd to remove a tdb when it has become
1002 corrupted.

1142 =============================
1143 Release Notes for Samba 3.0.5
1144 July 20, 2004
1145 =============================
1147 Please note that Samba 3.0.5 is identical to Samba 3.0.4 with
1148 the exception of correcting the two security issues outlined
1149 below.
1151 ######################## SECURITY RELEASE ########################
1153 Summary: Multiple Potential Buffer Overruns in Samba 3.0.x
1154 CVE ID: CAN-2004-0600, CAN-2004-0686
1155 (http://cve.mitre.org/)
1158 This is the latest stable release of Samba. This is the version
1159 that production Samba servers should be running for all current
1160 bug-fixes.
1162 It has been confirmed that versions of Samba 3 prior to v3.0.4
1163 are vulnerable to two potential buffer overruns. The individual
1164 details are given below.
1166 -------------
1167 CAN-2004-0600
1168 -------------
1170 Affected Versions: Samba 3.0.2 and later
1172 The internal routine used by the Samba Web Administration
1173 Tool (SWAT v3.0.2 and later) to decode the base64 data
1174 during HTTP basic authentication is subject to a buffer
1175 overrun caused by an invalid base64 character. It is
1176 recommended that all Samba v3.0.2 or later installations
1177 running SWAT either (a) upgrade to v3.0.5, or (b) disable
1178 the swat administration service as a temporary workaround.
1180 This same code is used internally to decode the
1181 sambaMungedDial attribute value when using the ldapsam
1182 passdb backend. While we do not believe that the base64
1183 decoding routines used by the ldapsam passdb backend can
1184 be exploited, sites using an LDAP directory service with
1185 Samba are strongly encouraged to verify that the DIT only
1186 allows write access to sambaSamAccount attributes by a
1187 sufficiently authorized user.
1189 The Samba Team would like to heartily thank Evgeny Demidov
1190 for analyzing and reporting this bug.
1192 -------------
1193 CAN-2004-0686
1194 -------------
1196 Affected Versions: Samba 3.0.0 and later
1198 A buffer overrun has been located in the code used to support
1199 the 'mangling method = hash' smb.conf option. Please be aware
1200 that the default setting for this parameter is 'mangling method
1201 = hash2' and therefore not vulnerable.
1203 Affected Samba 3 installations can avoid this possible security
1204 bug by using the default hash2 mangling method. Server
1205 installations requiring the hash mangling method are encouraged
1206 to upgrade to Samba 3.0.5.
1209 ##################################################################
1211 --------------------------------------------------
1213 =============================
1214 Release Notes for Samba 3.0.4
1215 May 8, 2004
1216 =============================
1218 Common bugs fixed in Samba 3.0.4 include:
1220 o Password changing after applying the patch described in
1221 the Microsoft KB828741 article to Windows clients.
1222 o Crashes in smbd.
1223 o Managing print jobs via Windows on Big-Endian servers.

1781 Release Notes for Samba 3.0.2a
1782 February 13, 2004
1783 ==============================
1785 Samba 3.0.2a is a minor patch release for the 3.0.2 code base
1786 to address, in particular, a problem when using pdbedit to
1787 sanitize (--force-initialized-passwords) Samba's tdbsam
1788 backend. This is the latest stable release of Samba. This
1789 is the version that all production Samba servers should be
1790 running for all current bug-fixes.
1792 ******************* Attention! Achtung! Kree! *********************
1794 Beginning with Samba 3.0.2, passwords for accounts with a last
1795 change time (LCT-XXX in smbpasswd, sambaPwdLastSet attribute in
1796 ldapsam, etc...) of zero (0) will be regarded as uninitialized
1797 strings. This will cause authentication to fail for such
1798 accounts. If you have valid passwords that meet this criteria,
1799 you must update the last change time to a non-zero value. If you
1800 do not, then 'pdbedit --force-initialized-passwords' will disable
1801 these accounts and reset the password hashes to a string of X's.
1803 ******************* Attention! Achtung! Kree! *********************

1855 Release Notes for Samba 3.0.2
1856 February 9, 2004
1857 =============================
1859 It has been confirmed that previous versions of Samba 3.0 are
1860 susceptible to a password initialization bug that could grant an
1861 attacker unauthorized access to a user account created by the
1862 mksmbpasswd.sh shell script.
1864 The Common Vulnerabilities and Exposures project (cve.mitre.org)
1865 has assigned the name CAN-2004-0082 to this issue.
1867 Samba administrators not wishing to upgrade to the current
1868 version should download the 3.0.2 release, build the pdbedit
1869 tool, and run
1871 root# pdbedit-3.0.2 --force-initialized-passwords
1873 This will disable all accounts not possessing a valid password
1874 (e.g. the password field has been set a string of X's).
1876 Samba servers running 3.0.2 are not vulnerable to this bug
1877 regardless of whether or not pdbedit has been used to sanitize
1878 the passdb backend.
1880 Some of the more visible bugs in 3.0.1 addressed in the 3.0.2
1881 release include:
1883 o Joining a Samba domain from Pre-SP2 Windows 2000 clients.
1884 o Logging onto a Samba domain from Windows XP clients.
1885 o Problems with the %U and %u smb.conf variables in relation to
1886 Windows 9x/ME clients.
1887 o Kerberos failures due to an invalid in memory keytab detection
1888 test.
1889 o Updates to the ntlm_auth tool.
1890 o Fixes for various SMB signing errors.
1891 o Better separation of WINS and DNS queries for domain controllers.
1892 o Issues with nss_winbind FreeBSD and Solaris.
1893 o Several crash bugs in smbd and winbindd.
1894 o Output formatting fixes for smbclient for better compatibility
1895 with scripts based on the 2.2 version.

2235 o Refuse to configure if --with-expsam=$BACKEND was used but no
2236 libraries were found for $BACKEND.
2237 o Move sysquotas autoconf tests to a separate file.
2238 o Match W2K w.r.t. writelock and writeclose. Samba4 torture

2324 o Apply patches to fix iconv detection for FreeBSD.
2325 o Do not allow the 'guest account' to be added to a passdb backend
2326 using smbpasswd or pdbedit (bug 624).
2327 o Save LDFLAGS during iconv detection (bug 57).
2328 o Run krb5 logins through the username map if the winbindd
2329 lookup fails (bug 698).
2330 o Add const for lp_set_name_resolve_order() to avoid compiler
2331 warnings (bug 471).
2332 o Add support for the %i macro in smb.conf to stand in for the for
2333 the local IP address to which a client connected.
2334 o Allow winbindd to match local accounts to domain SID when
2335 'winbind trusted domains only = yes' (bug 680).
2336 o Remove code in idmap_ldap that searches the user suffix and group
2337 suffix. It's not needed and provides inconsistent functionality
2338 from the tdb backend.
2339 o Patch to handle munged dial string for Windows 2000 TSE.
2340 Thanks to Gaz de France, Direction de la Recherche, Service
2341 Informatique Métier for their supporting this work by Aurelien
2342 Degrémont <adegremont@idealx.com>.
2343 o Correct the "smbldap_open: cannot access when not root error"
2344 messages when looking up group information (bug 281).
2345 o Skip over the winbind separator when looking up a user.
2346 This fixes the bug that prevented local users from
2347 matching an AD user when not running winbindd (bug 698).
2348 o Fix a problem with configure on *BSD systems. Make sure
2349 we add -liconv etc to LDFLAGS.
2350 o Fix core dump bug when "security = server" and the authentication
2351 server goes away.
2352 o Correct crash bug due to an empty munged dial string.
2353 o Show files locked by a specific user (smbstatus -u 'user')
2354 (bug 590).
2355 o Fix bug preventing print jobs from display in the queue
2356 monitor used by Windows NT and later clients (bug 660).
2357 o Fix several reported problems with point-n-print from
2358 Windows 2000/XP clients due to a bug in the EnumPrinterDataEx()
2359 reply (bug 338, 527 & 643).
2360 o Fix a handful of potential memory leaks in the LDAP code used
2361 by ldapsam[_compat] and the LDAP idmap backend.
2362 o Fix for pdbedit error code returns (bug 763).
2363 o Make sure we only enumerate group mapping entries (not
2364 /etc/group) even when doing local aliases.
2365 o Relax check on the pipe name in a dce/rpc bind response to work
2366 around issues with establishing trusts to a Windows 2003 domain.
2367 o Ensure we mangle names ending in '.' in hash2 mangling method.
2368 o Correct parsing issues with munged dial string.
2369 o Fix bugs in quota support for XFS.
2370 o Add a cleaner method for applications that need to provide
2371 name->SID mappings to do this via NSS rather than having to
2372 know the winbindd pipe protocol.
2373 o Adds a variant of the winbindd_getgroups() call called
2374 winbindd_getusersids() that provides direct SID->SIDs listing of
2375 a users supplementary groups. This is enough to allow non-Samba
2376 applications to do ACL checking.
2377 o Make sure we don't append the 'ldap suffix' when writing out the
2378 'ldap XXX suffix' values in SWAT (bug 328).
2379 o Fix renames across file systems.
2380 o Ensure that items in a list of strings containing whitespace are
2381 written out surrounded by single quotes. This means that both
2382 double and single quotes are now used to surround strings in
2383 smb.conf (bug 481).
2384 o Enable SWAT to correctly determine if winbindd is running (bug
2385 398).
2386 o Include WWW-Authenticate field in 401 response for bad auth
2387 attempt (bug 629).
2388 o Add support for NTLM2 (NTLMv2 session security).
2389 o Add support for variable-length session keys.
2390 o More privilege fixes for group enumeration in LDAP (bug 281).
2391 o Use the dns name (or IP) as the originating client name when
2392 using CUPS (bug 467).
2393 o Fix various SMB signing bugs.
2394 o Fix ACL propagation on a DFS root (bug 263).
2395 o Disable NTLM2 for RPC pipes.
2396 o Allow the client to specify the NTLM2 flags got NTLMSSP
2397 authentication.
2398 o Change the name of the job passed off to cups from "Test Page"
2399 to "smbprn.00000033 Test Page" so that we can get the smb
2400 jobid back. This allow users to delete jobs with cups printing
2401 backend (partial work on bug 770).
2402 o Fix build of winbindd with static pdb modules.
2403 o Retrieve the correct ACL group bits if the file has an ACL
2404 (bug 802).
2405 o Implement "net rpc group members": Get members of a domain group
2406 in human-readable format.
2407 o Add MacOSX (Darwin) specific charset module code.
2408 o Use samr_dispinfo(level == 1) for enumerating domain users so we
2409 can include the full name in gecos field (bug 587).
2410 o Add support for winbind's NSS library on FeeeBSD 5.1 (bug 797).
2411 o Implement 'net rpc group list [global|local|builtin]*' for a
2412 select listing of the respective user databases.
2413 o Don't automatically set NT status code flag unless client tells
2414 us it can cope.
2415 o Add 'net status [sessions|shares] [parseable]'.
2416 o Don't mistake pre-existing UNIX jobs for smb jobs (remainder of
2417 bug 770).
2418 o Add 'Replicator' and 'RAS Servers' to list of builtin SIDs
2419 (bug 608).
2420 o Fix inverted logic in hosts allow/deny checks caused by
2421 s/strcmp/strequal/ (bug 846).
2422 o Implement correct version SamrRemoveSidForeignDomain() (bug 252).
2423 o Fix typo in 'hash' mangling algorithm.
2424 o Support munged dial for ldapsam (bug 800).
2425 o Fix process_incoming_data() to return the number of bytes handled
2426 this call whether we have a complete PDU or not; fixes bug
2427 with multiple PDU request rpc's broken over SMBwriteX calls
2428 each.
2429 o Fix incorrect smb flags2 for connections to pre-NT servers
2430 (causes smbclient to fail to OS2 for example) (bug 821).
2431 o Update version string in smbldap-tools Makefile to 0.8.2.
2432 o Correct a problem with "net rpc vampire" mis-parsing the
2433 alias member info reply.
2434 o Ensure the ${libdir} is created by the installclientlib script.
2435 o Fix detection of Windows 2003 client architecture in the smb.conf
2436 %a variable.
2437 o Ensure that smbd calls the add user script for a missing UNIX
2438 user on kerberos auth call (bug 445).
2439 o Fix bugs in hosts allow/deny when using a mismatched
2440 network/netmask pair.
2441 o Protect alloc_sub_basic() from crashing when the source string
2442 is NULL (partial work on bug 687).
2443 o Fix spinlocks on IRIX.
2444 o Corrected some bad destination paths when running "configure
2445 --with-fhs".
2446 o Add packaging files for Fedora Core 1.
2447 o Correct bug in SWAT install script for non-english languages.
2448 o Support character set ISO-8859-1 internally (bug 558).
2449 o Fixed more LDAP access errors when looking up group mappings
2450 (bug 281).
2451 o Fix UNISTR2 length bug in LsaQueryInfo(3) that caused SID
2452 resolution to fail on local files on on domain members
2453 (bug 875).
2454 o Fix uninitialized variable in passdb.c.
2455 o Fix formal parameter type in get_static() in nsswitch/wins.c.
2456 o Fix problem mounting directories when mount.cifs is installed
2457 with the setuid bit on.

2467 The original 3.0.0 release notes follow
2468 =======================================
2469 WHATS NEW IN Samba 3.0.0
2470 September 24, 2003
2471 =======================================
2474 Major new features:
2475 -------------------
2477 1) Active Directory support. Samba 3.0 is now able to
2478 join a ADS realm as a member server and authenticate
2479 users using LDAP/Kerberos.
2481 2) Unicode support. Samba will now negotiate UNICODE on the wire
2482 and internally there is now a much better infrastructure for
2483 multi-byte and UNICODE character sets.
2485 3) New authentication system. The internal authentication system
2486 has been almost completely rewritten. Most of the changes are
2487 internal, but the new auth system is also very configurable.
2489 4) New default filename mangling system.
2491 5) A new "net" command has been added. It is somewhat similar to
2492 the "net" command in windows. Eventually we plan to replace
2493 numerous other utilities (such as smbpasswd) with subcommands
2494 in "net".
2496 6) Samba now negotiates NT-style status32 codes on the wire. This
2497 improves error handling a lot.
2499 7) Better Windows 2000/XP/2003 printing support including publishing
2500 printer attributes in active directory.
2502 8) New loadable module support for passdb backends and character
2503 sets.
2505 9) New default dual-daemon winbindd support for better performance.
2507 10) Support for migrating from a Windows NT 4.0 domain to a Samba
2508 domain and maintaining user, group and domain SIDs.
2510 11) Support for establishing trust relationships with Windows NT 4.0
2511 domain controllers.
2513 12) Initial support for a distributed Winbind architecture using
2514 an LDAP directory for storing SID to uid/gid mappings.
2516 13) Major updates to the Samba documentation tree.
2518 14) Full support for client and server SMB signing to ensure
2519 compatibility with default Windows 2003 security settings.
2521 15) Improvement of ACL mapping features based on code donated by
2522 Andreas Grünbacher.
2525 Plus lots of other improvements!
2528 Additional Documentation
2529 ------------------------
2531 Please refer to Samba documentation tree (included in the docs/
2532 subdirectory) for extensive explanations of installing, configuring
2533 and maintaining Samba 3.0 servers and clients. It is advised to
2534 begin with the Samba-HOWTO-Collection for overviews and specific
2535 tasks (the current book is up to approximately 400 pages) and to
2536 refer to the various man pages for information on individual options.
2538 We are very glad to be able to include the second edition of
2539 "Using Samba" by Jay Ts, Robert Eckstein, and David Collier-Brown
2540 (O'Reilly & Associates) in this release. The book is available
2541 on-line at http://samba.org/samba/docs/ and is included with
2542 the Samba Web Administration Tool (SWAT). Thanks to the authors and
2543 publisher for making "Using Samba" under the GNU Free Documentation
2544 License.
2547 ######################################################################
2548 Upgrading from a previous Samba 3.0 beta
2549 ########################################
2551 Beginning with Samba 3.0.0beta3, the RID allocation functions
2552 have been moved into winbindd. Previously these were handled
2553 by each passdb backend. This means that winbindd must be running
2554 to automatically allocate RIDs for users and/or groups. Otherwise,
2555 smbd will use the 2.2 algorithm for generating new RIDs.
2557 If you are using 'passdb backend = tdbsam' with a previous Samba
2558 3.0 beta release (or possibly alpha), it may be necessary to
2559 move the RID_COUNTER entry from /usr/local/samba/private/passdb.tdb
2560 to winbindd_idmap.tdb. To do this:
2562 1) Ensure that winbindd_idmap.tdb exists (launch winbindd at least
2563 once)
2564 2) build tdbtool by executing 'make tdbtool' in the source/tdb/
2565 directory
2566 3) run: (note that 'tdb>' is the tool's prompt for input)
2568 root# ./tdbtool /usr/local/samba/private/passdb.tdb
2569 tdb> show RID_COUNTER
2570 key 12 bytes
2571 RID_COUNTER
2572 data 4 bytes
2573 [000] 0A 52 00 00 .R.
2575 tdb> move RID_COUNTER /usr/local/samba/var/locks/winbindd_idmap.tdb
2576 ....
2577 record moved
2579 If you are using 'passdb backend = ldapsam', it will be necessary to
2580 store idmap entries in the LDAP directory as well (i.e. idmap backend
2581 = ldap). Refer to the 'net idmap' command for more information on
2582 migrating SID<->UNIX id mappings from one backend to another.
2584 If the RID_COUNTER record does not exist, then these instructions are
2585 unneccessary and the new RID_COUNTER record will be correctly generated
2586 if needed.

2768 upgrade databases as they are opened (if necessary), but downgrading
2769 from 3.0 to 2.2 is an unsupported path.
2771 Name Description Backup?
2772 ---- ----------- -------
2773 account_policy User policy settings yes
2774 gencache Generic caching db no
2775 group_mapping Mapping table from Windows yes
2776 groups/SID to unix groups
2777 winbindd_idmap ID map table from SIDS to UNIX yes
2778 uids/gids.
2779 namecache Name resolution cache entries no
2780 netsamlogon_cache Cache of NET_USER_INFO_3 structure no
2781 returned as part of a successful
2782 net_sam_logon request
2783 printing/*.tdb Cached output from 'lpq no
2784 command' created on a per print
2785 service basis
2786 registry Read-only samba registry skeleton no
2787 that provides support for exporting
2788 various db tables via the winreg RPCs
2791 Changes in Behavior
2792 -------------------
2794 The following issues are known changes in behavior between Samba 2.2 and
2795 Samba 3.0 that may affect certain installations of Samba.
2797 1) When operating as a member of a Windows domain, Samba 2.2 would
2798 map any users authenticated by the remote DC to the 'guest account'
2799 if a uid could not be obtained via the getpwnam() call. Samba 3.0
2800 rejects the connection as NT_STATUS_LOGON_FAILURE. There is no
2801 current work around to re-establish the 2.2 behavior.
2803 2) When adding machines to a Samba 2.2 controlled domain, the
2804 'add user script' was used to create the UNIX identity of the
2805 machine trust account. Samba 3.0 introduces a new 'add machine
2806 script' that must be specified for this purpose. Samba 3.0 will
2807 not fall back to using the 'add user script' in the absence of
2808 an 'add machine script'
2811 ######################################################################
2812 Passdb Backends and Authentication
2813 ##################################
2815 There have been a few new changes that Samba administrators should be
2816 aware of when moving to Samba 3.0.
2818 1) encrypted passwords have been enabled by default in order to
2819 inter-operate better with out-of-the-box Windows client
2820 installations. This does mean that either (a) a samba account
2821 must be created for each user, or (b) 'encrypt passwords = no'
2822 must be explicitly defined in smb.conf.
2824 2) Inclusion of new 'security = ads' option for integration
2825 with an Active Directory domain using the native Windows
2826 Kerberos 5 and LDAP protocols.
2828 MIT kerberos 1.3.1 supports the ARCFOUR-HMAC-MD5 encryption
2829 type which is neccessary for servers on which the
2830 administrator password has not been changed, or kerberos-enabled
2831 SMB connections to servers that require Kerberos SMB signing.
2832 Besides this one difference, either MIT or Heimdal Kerberos
2833 distributions are usable by Samba 3.0.
2836 Samba 3.0 also includes the possibility of setting up chains
2837 of authentication methods (auth methods) and account storage
2838 backends (passdb backend). Please refer to the smb.conf(5)
2839 man page for details. While both parameters assume sane default
2840 values, it is likely that you will need to understand what the
2841 values actually mean in order to ensure Samba operates correctly.
2843 The recommended passdb backends at this time are
2845 * smbpasswd - 2.2 compatible flat file format
2846 * tdbsam - attribute rich database intended as an smbpasswd
2847 replacement for stand alone servers
2848 * ldapsam - attribute rich account storage and retrieval
2849 backend utilizing an LDAP directory.
2850 * ldapsam_compat - a 2.2 backward compatible LDAP account
2851 backend
2853 Certain functions of the smbpasswd(8) tool have been split between the
2854 new smbpasswd(8) utility, the net(8) tool, and the new pdbedit(8)
2855 utility. See the respective man pages for details.
2858 ######################################################################
2859 LDAP
2860 ####
2862 This section outlines the new features affecting Samba / LDAP
2863 integration.
2865 New Schema
2866 ----------
2868 A new object class (sambaSamAccount) has been introduced to replace
2869 the old sambaAccount. This change aids us in the renaming of
2870 attributes to prevent clashes with attributes from other vendors.
2871 There is a conversion script (examples/LDAP/convertSambaAccount) to
2872 modify and LDIF file to the new schema.
2874 Example:
2876 $ ldapsearch .... -b "ou=people,dc=..." > sambaAcct.ldif
2877 $ convertSambaAccount --sid=<Domain SID> \
2878 --input=sambaAcct.ldif --output=sambaSamAcct.ldif \
2879 --changetype=[modify|add]
2881 The <DOM SID> can be obtained by running 'net getlocalsid
2882 <DOMAINNAME>' on the Samba PDC as root. The changetype determines
2883 the format of the generated LDIF output--either create new entries
2884 or modify existing entries.
2886 The old sambaAccount schema may still be used by specifying the
2887 "ldapsam_compat" passdb backend. However, the sambaAccount and
2888 associated attributes have been moved to the historical section of
2889 the schema file and must be uncommented before use if needed.
2890 The 2.2 object class declaration for a sambaAccount has not changed
2891 in the 3.0 samba.schema file.
2893 Other new object classes and their uses include:
2895 * sambaDomain - domain information used to allocate rids
2896 for users and groups as necessary. The attributes are added
2897 in 'ldap suffix' directory entry automatically if
2898 an idmap uid/gid range has been set and the 'ldapsam'
2899 passdb backend has been selected.
2901 * sambaGroupMapping - an object representing the
2902 relationship between a posixGroup and a Windows
2903 group/SID. These entries are stored in the 'ldap
2904 group suffix' and managed by the 'net groupmap' command.
2906 * sambaUnixIdPool - created in the 'ldap idmap suffix' entry
2907 automatically and contains the next available 'idmap uid' and
2908 'idmap gid'
2910 * sambaIdmapEntry - object storing a mapping between a
2911 SID and a UNIX uid/gid. These objects are created by the
2912 idmap_ldap module as needed.
2914 * sambaSidEntry - object representing a SID alone, as a Structural
2915 class on which to build the sambaIdmapEntry.
2918 New Suffix for Searching
2919 ------------------------
2921 The following new smb.conf parameters have been added to aid in directing
2922 certain LDAP queries when 'passdb backend = ldapsam://...' has been
2923 specified.
2925 * ldap suffix - used to search for user and computer accounts
2926 * ldap user suffix - used to store user accounts
2927 * ldap machine suffix - used to store machine trust accounts
2928 * ldap group suffix - location of posixGroup/sambaGroupMapping entries
2929 * ldap idmap suffix - location of sambaIdmapEntry objects
2931 If an 'ldap suffix' is defined, it will be appended to all of the
2932 remaining sub-suffix parameters. In this case, the order of the suffix
2933 listings in smb.conf is important. Always place the 'ldap suffix' first
2934 in the list.
2936 Due to a limitation in Samba's smb.conf parsing, you should not surround
2937 the DN's with quotation marks.
2940 IdMap LDAP support
2941 ------------------
2943 Samba 3.0 supports an ldap backend for the idmap subsystem. The
2944 following options would inform Samba that the idmap table should be
2945 stored on the directory server onterose in the "ou=idmap,dc=plainjoe,
2946 dc=org" partition.
2948 [global]
2949 ...
2950 idmap backend = ldap:ldap://onterose/
2951 ldap idmap suffix = ou=idmap,dc=plainjoe,dc=org
2952 idmap uid = 40000-50000
2953 idmap gid = 40000-50000
2955 This configuration allows winbind installations on multiple servers to
2956 share a uid/gid number space, thus avoiding the interoperability problems
2957 with NFS that were present in Samba 2.2.

2962 Trust Relationships and a Samba Domain
2963 ######################################
2965 Samba 3.0.0beta2 is able to utilize winbindd as the means of
2966 allocating uids and gids to trusted users and groups. More
2967 information regarding Samba's support for establishing trust
2968 relationships can be found in the Samba-HOWTO-Collection included
2969 in the docs/ directory of this release.
2971 First create your Samba PDC and ensure that everything is
2972 working correctly before moving on the trusts.
2974 To establish Samba as the trusting domain (named SAMBA) from a Windows NT
2975 4.0 domain named WINDOWS:
2977 1) create the trust account for SAMBA in "User Manager for Domains"
2978 2) connect the trust from the Samba domain using
2979 'net rpc trustdom establish GLASS'
2981 To create a trustlationship with SAMBA as the trusted domain:
2983 1) create the initial trust account for GLASS using
2984 'smbpasswd -a -i GLASS'. You may need to create a UNIX
2985 account for GLASS$ prior to this step (depending on your
2986 local configuration).
2987 2) connect the trust from a WINDOWS DC using "User Manager
2988 for Domains"
2990 Now join winbindd on the Samba PDC to the SAMBA domain using
2991 the normal steps for adding a Samba server to an NT4 domain:
2992 (note that smbd & nmbd must be running at this point)
2994 root# net rpc join -U root
2995 Password: <enter root password from smbpasswd file here>
2997 Start winbindd and test the join with 'wbinfo -t'.
2999 Now test the trust relationship by connecting to the SAMBA DC
3000 (e.g. POGO) as a user from the WINDOWS domain:
3002 $ smbclient //pogo/netlogon -U Administrator -W WINDOWS
3003 Password:
3005 Now connect to the WINDOWS DC (e.g. CRYSTAL) as a Samba user:
3007 $ smbclient //crystal/netlogon -U root -W WINDOWS
3008 Password:

3011 Changes in Winbind
3012 ##################
3014 Beginning with Samba3.0.0beta3, winbindd has been given new account
3015 manage functionality equivalent to the 'add user script' family of
3016 smb.conf parameters. The idmap design has also been changed to
3017 centralize control of foreign SID lookups and matching to UNIX
3018 uids and gids.
3021 Brief Description of Changes
3022 ----------------------------
3024 1) The sid_to_uid() family of functions (smbd/uid.c) have been
3025 reverted to the 2.2.x design. This means that when resolving a
3026 SID to a UID or similar mapping:
3028 a) First consult winbindd
3029 b) perform a local lookup only if winbindd fails to
3030 return a successful answer
3032 There are some variations to this, but these two rules generally
3033 apply.
3035 2) All idmap lookups have been moved into winbindd. This means that
3036 a server must run winbindd (and support NSS) in order to achieve
3037 any mappings of SID to dynamically allocated UNIX ids. This was
3038 a conscious design choice.
3040 3) New functions have been added to winbindd to emulate the 'add user
3041 script' family of smbd functions without requiring that external
3042 scripts be defined. This functionality is controlled by the 'winbind
3043 enable local accounts' smb.conf parameter (enabled by default).
3045 However, this account management functionality is only supported
3046 in a local tdb (winbindd_idmap.tdb). If these new UNIX accounts
3047 must be shared among multiple Samba servers (such as a PDC and BDCs),
3048 it will be necessary to define your own 'add user script', et. al.
3049 programs that place the accounts/groups in some form of directory
3050 such as NIS or LDAP. This requirement was deemed beyond the scope
3051 of winbind's account management functions. Solutions for
3052 distributing UNIX system information have been deployed and tested
3053 for many years. We saw no need to reinvent the wheel.
3055 4) A member of a Samba controlled domain running winbindd is now able
3056 to map domain users directly onto existing UNIX accounts while still
3057 automatically creating accounts for trusted users and groups. This
3058 behavior is controlled by the 'winbind trusted domains only' smb.conf
3059 parameter (disabled by default to provide 2.2.x winbind behavior).
3061 5) Group mapping support is wrapped in the local_XX_to_XX() functions
3062 in smbd/uid.c. The reason that group mappings are not included
3063 in winbindd is because the purpose of Samba's group map is to
3064 match any Windows SID with an existing UNIX group. These UNIX
3065 groups can be created by winbindd (see next section), but the
3066 SID<->gid mapping is retreived by smbd, not winbindd.
3069 Examples
3070 --------
3072 * security = server running winbindd to allocate accounts on demand
3074 * Samba PDC running winbindd to handle the automatic creation of UNIX
3075 identities for machine trust accounts
3077 * Automtically creating UNIX user and groups when migrating a Windows NT
3078 4.0 PDC to a Samba PDC. Winbindd must be running when executing
3079 'net rpc vampire' for this to work.
