1 WHATS NEW IN Samba 3.0.1pre3
3 ==============================
5 This is a preview release of the Samba 3.0.1 code base and is
6 provided for testing only. This release is *not* intended for
7 production servers. Use at your own risk.
9 There have been several bug fixes since the 3.0.0 releaser that
10 we feel are important to make available to the Samba community
11 for wider testings. See the "Changes" section for details on
15 ######################################################################
18 Changes since 3.0.1pre2
19 -----------------------
21 Please refer to the CVS log for the SAMBA_3_0 branch for complete
24 1) Skip over the winbind separator when looking up a user.
25 This fixes the bug that prevented local users from
26 matching an AD user when not running winbindd (bug 698).
27 2) Fix a problem with configure on *BSD systems. Make sure
28 we add -liconv etc to LDFLAGS.
29 3) Fix core dump bug when security=server and the server goes
31 4) Correct crash bug due to an empty munged dial string.
32 5) Show locked files for -u <user> (bug 590).
33 6) Fix bug preventing print jobs from display in the queue
34 monitor used by Windows NT and later clients (bug 660).
35 7) Fix several reported problems with point-n-print from
36 Windows 2000/XP clients due to a bug in the EnumPrinterDataEx()
37 reply (bug 338, 527 & 643).
38 8) Fix a handful of potential memory leaks in the LDAP code used
39 by ldapsam[_compat] and the LDAP idmap backend.
42 Changes since 3.0.1pre1
43 -----------------------
45 1) Match Samba 2.2 behavior; make ACB_NORMAL the default ACB value.
46 2) Updated Japanese welcome file in SWAT.
47 3) Fix to nt-time <-> unix-time functions reversible.
48 4) Ensure that winbindd uses the the escaped DN when querying
50 5) Fix portability issues when compiling (bug 505, 550)
51 6) Compile fix for tdbbackup when Samba needs to override
52 non-C99 compliant implementations of snprintf().
53 7) Use @PICSUFFIX@ instead of .po in Makefile.in (bug 574).
54 8) Make sure we break out of samsync loop on error.
55 9) Ensure error code path doesn't free unmalloc()'d memory
57 10) Add configure test for krb5_keytab_entry keyblock vs key
60 12) Modified testparm so that all output so all debug output goes
61 to stderr, and all file processing goes to stdout.
62 13) Fix error return code for BUFFER_TOO_SMALL in smbcacls
64 14) Fix "NULL dest in safe_strcpy()" log message by ensuring that
65 we have a devmode before copying a string to the devicename.
66 15) Support mapping REALM.COM\user to a local user account (without
67 running winbindd) for compatibility with 2.2.x release.
68 16) Ensure we don't use mmap() on blacklisted systems.
69 17) fixed a number of bugs and memory leaks in the AIX
71 18) Call initgroups() in SWAT before becomming the user so that
72 secondary group permissions can be used when writing to
74 19) Fix signing problems when reverse connecting back to a
75 client for printer notify
76 20) Fix signing problems caused by a miss-sequence bug.
77 21) Missing map in errormap for ERROR_MORE_DATA -> ERRDOS, ERRmoredata.

86 26) Change in behavior to Not only change the effective uid but also
87 the real uid when becoming unprivileged.
88 27) Cope with Exchange 5.5 cleartext pop password auth.
89 28) New files for support of initshutdown pipe. Win2k doesn't

93 30) Include fixes for libsmbclient build problems.
94 31) Missing UNIX -> DOS codepage conversion in lanman.c.
95 32) Allow DFMS-S filenames can now have arbitrary case (bug 667).

114 up value which just happens to be less than sizeof(fstring).
116 45) Add ldaplibs to pdbedit link line (bug 651).
117 46) Fix crash bug in smbclient completion (bug 659).
118 47) Fix packet length for browse list reply (bug 771).
119 48) Fix coredump in cli_get_backup_list().

132 57) Add support for the %i macro in smb.conf to stand in for the for
133 the local IP address to which a client connected.
134 58) Allow winbindd to match local accounts to domain SID when
135 'winbind trusted domains only = yes' (bug 680).
136 59) Remove code in idmap_ldap that searches the user suffix and group
137 suffix. It's not needed and provides inconsistent functionality
138 from the tdb backend.
139 60) Patch to handle munged dial string for Windows 200 TSE.
140 61) Correct the "smbldap_open: cannot access when not root error"
141 messages when looking up group information (bug 281).
149 * mangled map (deprecated)
152 * mangled stack (unused)
155 1) Change the interface for init_unistr2 to not take a length
156 but a flags field. We were assuming that
157 2*strlen(mb_string) == length of ucs2-le string. (bug 480).
158 2) Allow d_printf() to handle strings with escaped quotation
159 marks since the msg file includes the escape character (bug 489).

166 7) Testparm output fixes for clarity.
167 8) Fix broken wins hook functionality -- i18n bug (bug 528).
168 9) Take care of condition where DOS and NT error codes must differ.
169 10) Default to using only built-in charsets when a working iconv
170 implementation cannot be located.
171 11) Wrap internals of sys_setgroups() so the sys_XX() call can
172 be done unconditionally (bug 550).
173 12) Remove duplicate smbspool link on SWAT's front page (bug 541).
174 13) Save and restore CFLAGS before/after AC_PROG_CC. Ensures that
175 --enable-debug=[yes|no] works correctly.
176 14) Allow ^C to interrupt smbpasswd if using our getpass
177 (e.g. smbpasswd command).

180 files marked as read-only.
181 17) Portability fix bugs 546 - 549).
182 18) Explicitly initialize the value of AR for vendor makes that don't
183 do this (e.g. HPUX 11). (bug 552).
184 19) More i18n fixes for SWAT (bug 413).
185 20) Change the cwd before the postexec script to ensure that a

188 is rebooted (bug 437).
189 22) Fix incorrect mode sum (bug 562).
190 23) Canonicalize SMB_INFO_ALLOCATION in the same was as
191 SMB_FS_FULL_SIZE_INFORMATION (bug 564).
192 24) Add script to generate *msg files.
193 25) Add Dutch SWAT translation file.
194 26) Make sure to call get_user_groups() with the full winbindd
195 name for a user if he/she has one (bug 406).
196 27) Fix up error code returns from Samba4 tester. Ensure invalid
197 paths are validated the same way.
198 28) Allow Samba3 to pass the Samba4 RAW-READ tests.
199 29) Refuse to configure if --with-expsam=$BACKEND was used but no
200 libraries were found for $BACKEND.
201 30) Move sysquotas autoconf tests to a separate file.
202 31) Match W2K w.r.t. writelock and writeclose. Samba4 torture
204 32) Make sure that the files that contain the static_init_$subsystem;
205 macro get recompiled after configure by removing the object
207 33) Ensure canceling a blocking lock returns the correct error
209 34) Match Samba 2.2, and make ACB_NORMAL the default ACB value.
213 ######################################################################
215 =======================================
216 The original 3.0.0 release notes follow
217 =======================================
223 1) Active Directory support. Samba 3.0 is now able to
224 join a ADS realm as a member server and authenticate
225 users using LDAP/Kerberos.
227 2) Unicode support. Samba will now negotiate UNICODE on the wire
228 and internally there is now a much better infrastructure for
229 multi-byte and UNICODE character sets.
231 3) New authentication system. The internal authentication system
232 has been almost completely rewritten. Most of the changes are
233 internal, but the new auth system is also very configurable.
235 4) New default filename mangling system.
237 5) A new "net" command has been added. It is somewhat similar to
238 the "net" command in windows. Eventually we plan to replace
239 numerous other utilities (such as smbpasswd) with subcommands
242 6) Samba now negotiates NT-style status32 codes on the wire. This
243 improves error handling a lot.
245 7) Better Windows 2000/XP/2003 printing support including publishing
246 printer attributes in active directory.
248 8) New loadable module support for passdb backends and character
251 9) New default dual-daemon winbindd support for better performance.
253 10) Support for migrating from a Windows NT 4.0 domain to a Samba
254 domain and maintaining user, group and domain SIDs.
256 11) Support for establishing trust relationships with Windows NT 4.0
259 12) Initial support for a distributed Winbind architecture using
260 an LDAP directory for storing SID to uid/gid mappings.
262 13) Major updates to the Samba documentation tree.
264 14) Full support for client and server SMB signing to ensure
265 compatibility with default Windows 2003 security settings.
267 15) Improvement of ACL mapping features based on code donated by
271 Plus lots of other improvements!
274 Additional Documentation
275 ------------------------
277 Please refer to Samba documentation tree (included in the docs/
278 subdirectory) for extensive explanations of installing, configuring
279 and maintaining Samba 3.0 servers and clients. It is advised to
280 begin with the Samba-HOWTO-Collection for overviews and specific
281 tasks (the current book is up to approximately 400 pages) and to
282 refer to the various man pages for information on individual options.
284 We are very glad to be able to include the second edition of
285 "Using Samba" by Jay Ts, Robert Eckstein, and David Collier-Brown
286 (O'Reilly & Associates) in this release. The book is available
287 on-line at http://samba.org/samba/docs/ and is included with
288 the Samba Web Administration Tool (SWAT). Thanks to the authors and
289 publisher for making "Using Samba" under the GNU Free Documentation
293 ######################################################################
294 Upgrading from a previous Samba 3.0 beta
295 ########################################
297 Beginning with Samba 3.0.0beta3, the RID allocation functions
298 have been moved into winbindd. Previously these were handled
299 by each passdb backend. This means that winbindd must be running
300 to automatically allocate RIDs for users and/or groups. Otherwise,
301 smbd will use the 2.2 algorithm for generating new RIDs.
303 If you are using 'passdb backend = tdbsam' with a previous Samba
304 3.0 beta release (or possibly alpha), it may be necessary to
305 move the RID_COUNTER entry from /usr/local/samba/private/passdb.tdb
306 to winbindd_idmap.tdb. To do this:
308 1) Ensure that winbindd_idmap.tdb exists (launch winbindd at least
310 2) build tdbtool by executing 'make tdbtool' in the source/tdb/
312 3) run: (note that 'tdb>' is the tool's prompt for input)
314 root# ./tdbtool /usr/local/samba/private/passdb.tdb
315 tdb> show RID_COUNTER
319 [000] 0A 52 00 00 .R.
321 tdb> move RID_COUNTER /usr/local/samba/var/locks/winbindd_idmap.tdb
325 If you are using 'passdb backend = ldapsam', it will be necessary to
326 store idmap entries in the LDAP directory as well (i.e. idmap backend
327 = ldap). Refer to the 'net idmap' command for more information on
328 migrating SID<->UNIX id mappings from one backend to another.
330 If the RID_COUNTER record does not exist, then these instructions are
331 unneccessary and the new RID_COUNTER record will be correctly generated

337 Upgrading from Samba 2.2
338 ########################
340 This section is provided to help administrators understand the details
341 involved with upgrading a Samba 2.2 server to Samba 3.0.
347 Many of the options to the GNU autoconf script have been modified
348 in the 3.0 release. The most noticeable are:
350 * removal of --with-tdbsam (is now included by default; see section
351 on passdb backends and authentication for more details)
353 * --with-ldapsam is now on used to provided backward compatible
354 parameters for LDAP enabled Samba 2.2 servers. Refer to the passdb
355 backend and authentication section for more details
357 * inclusion of non-standard passdb modules may be enabled using
358 --with-expsam. This includes an XML backend and a mysql backend.
360 * removal of --with-msdfs (is now enabled by default)
362 * removal of --with-ssl (no longer supported)
364 * --with-utmp now defaults to 'yes' on supported systems
366 * --with-sendfile-support is now enabled by default on supported
373 This section contains a brief listing of changes to smb.conf options
374 in the 3.0.0 release. Please refer to the smb.conf(5) man page for
375 complete descriptions of new or modified parameters.
377 Removed Parameters (order alphabetically):
380 * alternate permissions
383 * code page directory

478 * ldap machine suffix
482 General Configuration
483 ---------------------
487 Modified Parameters (changes in behavior):
489 * encrypt passwords (enabled by default)
490 * mangling method (set to 'hash2' by default)
493 * restrict anonymous (integer value)

497 * winbind cache time (increased to 5 minutes)
498 * winbind uid (deprecated in favor of 'idmap uid')
499 * winbind gid (deprecated in favor of 'idmap gid')
505 This section contains brief descriptions of any new databases
506 introduced in Samba 3.0. Please remember to backup your existing
507 ${lock directory}/*tdb before upgrading to Samba 3.0. Samba will
508 upgrade databases as they are opened (if necessary), but downgrading
509 from 3.0 to 2.2 is an unsupported path.
511 Name Description Backup?
512 ---- ----------- -------
513 account_policy User policy settings yes
514 gencache Generic caching db no
515 group_mapping Mapping table from Windows yes
516 groups/SID to unix groups
517 winbindd_idmap ID map table from SIDS to UNIX yes
519 namecache Name resolution cache entries no
520 netsamlogon_cache Cache of NET_USER_INFO_3 structure no
521 returned as part of a successful
522 net_sam_logon request
523 printing/*.tdb Cached output from 'lpq no
524 command' created on a per print
526 registry Read-only samba registry skeleton no
527 that provides support for exporting
528 various db tables via the winreg RPCs
534 The following issues are known changes in behavior between Samba 2.2 and
535 Samba 3.0 that may affect certain installations of Samba.
537 1) When operating as a member of a Windows domain, Samba 2.2 would
538 map any users authenticated by the remote DC to the 'guest account'
539 if a uid could not be obtained via the getpwnam() call. Samba 3.0
540 rejects the connection as NT_STATUS_LOGON_FAILURE. There is no
541 current work around to re-establish the 2.2 behavior.
543 2) When adding machines to a Samba 2.2 controlled domain, the
544 'add user script' was used to create the UNIX identity of the
545 machine trust account. Samba 3.0 introduces a new 'add machine
546 script' that must be specified for this purpose. Samba 3.0 will
547 not fall back to using the 'add user script' in the absence of
548 an 'add machine script'
551 ######################################################################
552 Passdb Backends and Authentication
553 ##################################
555 There have been a few new changes that Samba administrators should be
556 aware of when moving to Samba 3.0.
558 1) encrypted passwords have been enabled by default in order to
559 inter-operate better with out-of-the-box Windows client
560 installations. This does mean that either (a) a samba account
561 must be created for each user, or (b) 'encrypt passwords = no'
562 must be explicitly defined in smb.conf.
564 2) Inclusion of new 'security = ads' option for integration
565 with an Active Directory domain using the native Windows
566 Kerberos 5 and LDAP protocols.
568 MIT kerberos 1.3.1 supports the ARCFOUR-HMAC-MD5 encryption
569 type which is neccessary for servers on which the
570 administrator password has not been changed, or kerberos-enabled
571 SMB connections to servers that require Kerberos SMB signing.
572 Besides this one difference, either MIT or Heimdal Kerberos
573 distributions are usable by Samba 3.0.
576 Samba 3.0 also includes the possibility of setting up chains
577 of authentication methods (auth methods) and account storage
578 backends (passdb backend). Please refer to the smb.conf(5)
579 man page for details. While both parameters assume sane default
580 values, it is likely that you will need to understand what the
581 values actually mean in order to ensure Samba operates correctly.
583 The recommended passdb backends at this time are
585 * smbpasswd - 2.2 compatible flat file format
586 * tdbsam - attribute rich database intended as an smbpasswd
587 replacement for stand alone servers
588 * ldapsam - attribute rich account storage and retrieval
589 backend utilizing an LDAP directory.
590 * ldapsam_compat - a 2.2 backward compatible LDAP account
593 Certain functions of the smbpasswd(8) tool have been split between the
594 new smbpasswd(8) utility, the net(8) tool, and the new pdbedit(8)
595 utility. See the respective man pages for details.
598 ######################################################################
602 This section outlines the new features affecting Samba / LDAP
608 A new object class (sambaSamAccount) has been introduced to replace
609 the old sambaAccount. This change aids us in the renaming of attributes
610 to prevent clashes with attributes from other vendors. There is a
611 conversion script (examples/LDAP/convertSambaAccount) to modify and LDIF
612 file to the new schema.
616 $ ldapsearch .... -b "ou=people,dc=..." > old.ldif
617 $ convertSambaAccount <DOM SID> old.ldif new.ldif
619 The <DOM SID> can be obtained by running 'net getlocalsid <DOMAINNAME>'
620 on the Samba PDC as root.
622 The old sambaAccount schema may still be used by specifying the
623 "ldapsam_compat" passdb backend. However, the sambaAccount and
624 associated attributes have been moved to the historical section of
625 the schema file and must be uncommented before use if needed.
626 The 2.2 object class declaration for a sambaAccount has not changed
627 in the 3.0 samba.schema file.
629 Other new object classes and their uses include:
631 * sambaDomain - domain information used to allocate rids
632 for users and groups as necessary. The attributes are added
633 in 'ldap suffix' directory entry automatically if
634 an idmap uid/gid range has been set and the 'ldapsam'
635 passdb backend has been selected.
637 * sambaGroupMapping - an object representing the
638 relationship between a posixGroup and a Windows
639 group/SID. These entries are stored in the 'ldap
640 group suffix' and managed by the 'net groupmap' command.
642 * sambaUnixIdPool - created in the 'ldap idmap suffix' entry
643 automatically and contains the next available 'idmap uid' and
646 * sambaIdmapEntry - object storing a mapping between a
647 SID and a UNIX uid/gid. These objects are created by the
648 idmap_ldap module as needed.
650 * sambaSidEntry - object representing a SID alone, as a Structural
651 class on which to build the sambaIdmapEntry.
654 New Suffix for Searching
655 ------------------------
657 The following new smb.conf parameters have been added to aid in directing
658 certain LDAP queries when 'passdb backend = ldapsam://...' has been
661 * ldap suffix - used to search for user and computer accounts
662 * ldap user suffix - used to store user accounts
663 * ldap machine suffix - used to store machine trust accounts
664 * ldap group suffix - location of posixGroup/sambaGroupMapping entries
665 * ldap idmap suffix - location of sambaIdmapEntry objects
667 If an 'ldap suffix' is defined, it will be appended to all of the
668 remaining sub-suffix parameters. In this case, the order of the suffix
669 listings in smb.conf is important. Always place the 'ldap suffix' first
672 Due to a limitation in Samba's smb.conf parsing, you should not surround
673 the DN's with quotation marks.
679 Samba 3.0 supports an ldap backend for the idmap subsystem. The
680 following options would inform Samba that the idmap table should be
681 stored on the directory server onterose in the "ou=idmap,dc=plainjoe,
686 idmap backend = ldap:ldap://onterose/
687 ldap idmap suffix = ou=idmap,dc=plainjoe,dc=org
688 idmap uid = 40000-50000
689 idmap gid = 40000-50000
691 This configuration allows winbind installations on multiple servers to
692 share a uid/gid number space, thus avoiding the interoperability problems
693 with NFS that were present in Samba 2.2.
697 ######################################################################
698 Trust Relationships and a Samba Domain
699 ######################################
701 Samba 3.0.0beta2 is able to utilize winbindd as the means of
702 allocating uids and gids to trusted users and groups. More
703 information regarding Samba's support for establishing trust
704 relationships can be found in the Samba-HOWTO-Collection included
705 in the docs/ directory of this release.
707 First create your Samba PDC and ensure that everything is
708 working correctly before moving on the trusts.
710 To establish Samba as the trusting domain (named SAMBA) from a Windows NT
711 4.0 domain named WINDOWS:
713 1) create the trust account for SAMBA in "User Manager for Domains"
714 2) connect the trust from the Samba domain using
715 'net rpc trustdom establish GLASS'
717 To create a trustlationship with SAMBA as the trusted domain:
719 1) create the initial trust account for GLASS using
720 'smbpasswd -a -i GLASS'. You may need to create a UNIX
721 account for GLASS$ prior to this step (depending on your
722 local configuration).
723 2) connect the trust from a WINDOWS DC using "User Manager
726 Now join winbindd on the Samba PDC to the SAMBA domain using
727 the normal steps for adding a Samba server to an NT4 domain:
728 (note that smbd & nmbd must be running at this point)
730 root# net rpc join -U root
731 Password: <enter root password from smbpasswd file here>
733 Start winbindd and test the join with 'wbinfo -t'.
735 Now test the trust relationship by connecting to the SAMBA DC
736 (e.g. POGO) as a user from the WINDOWS domain:
738 $ smbclient //pogo/netlogon -U Administrator -W WINDOWS
741 Now connect to the WINDOWS DC (e.g. CRYSTAL) as a Samba user:
743 $ smbclient //crystal/netlogon -U root -W WINDOWS

750 Beginning with Samba3.0.0beta3, winbindd has been given new account
751 manage functionality equivalent to the 'add user script' family of
752 smb.conf parameters. The idmap design has also been changed to
753 centralize control of foreign SID lookups and matching to UNIX
757 Brief Description of Changes
758 ----------------------------
760 1) The sid_to_uid() family of functions (smbd/uid.c) have been
761 reverted to the 2.2.x design. This means that when resolving a
762 SID to a UID or similar mapping:
764 a) First consult winbindd
765 b) perform a local lookup only if winbindd fails to
766 return a successful answer
768 There are some variations to this, but these two rules generally
771 2) All idmap lookups have been moved into winbindd. This means that
772 a server must run winbindd (and support NSS) in order to achieve
773 any mappings of SID to dynamically allocated UNIX ids. This was
774 a conscious design choice.
776 3) New functions have been added to winbindd to emulate the 'add user
777 script' family of smbd functions without requiring that external
778 scripts be defined. This functionality is controlled by the 'winbind
779 enable local accounts' smb.conf parameter (enabled by default).
781 However, this account management functionality is only supported
782 in a local tdb (winbindd_idmap.tdb). If these new UNIX accounts
783 must be shared among multiple Samba servers (such as a PDC and BDCs),
784 it will be necessary to define your own 'add user script', et. al.
785 programs that place the accounts/groups in some form of directory
786 such as NIS or LDAP. This requirement was deemed beyond the scope
787 of winbind's account management functions. Solutions for
788 distributing UNIX system information have been deployed and tested
789 for many years. We saw no need to reinvent the wheel.
791 4) A member of a Samba controlled domain running winbindd is now able
792 to map domain users directly onto existing UNIX accounts while still
793 automatically creating accounts for trusted users and groups. This
794 behavior is controlled by the 'winbind trusted domains only' smb.conf
795 parameter (disabled by default to provide 2.2.x winbind behavior).
797 5) Group mapping support is wrapped in the local_XX_to_XX() functions
798 in smbd/uid.c. The reason that group mappings are not included
799 in winbindd is because the purpose of Samba's group map is to
800 match any Windows SID with an existing UNIX group. These UNIX
801 groups can be created by winbindd (see next section), but the
802 SID<->gid mapping is retreived by smbd, not winbindd.
808 * security = server running winbindd to allocate accounts on demand
810 * Samba PDC running winbindd to handle the automatic creation of UNIX
811 identities for machine trust accounts
813 * Automtically creating UNIX user and groups when migrating a Windows NT
814 4.0 PDC to a Samba PDC. Winbindd must be running when executing
815 'net rpc vampire' for this to work.
