2 Release Notes for Samba 3.0.5rc1
3 July 8, 2004
4 ================================
6 This is a release candidate snapshot of the Samba 3.0.5 code
7 base and should be considered for testing only. A release
8 candidate (RC) means that we are close to the final, stable
9 release and in provided for Quality Assurance (QA) purposes.
10 This release is *not* intended for production servers. Use
11 at your own risk.
13 There have been several bug fixes since the 3.0.4 release that
14 we feel are important to make available to the Samba community
15 for wider testings. See the "Changes" section for details on
16 exact updates.
18 Common bugs fixed in this 3.0.5rc1 include:
20 o Corrupt workgroup names in nmbd's browse.dat.
22 o Sharing violation errors commonly seen when opening
23 when serving Microsoft Office documents from a Samba
24 file share.
26 o Browsing problems caused by an apostrophe (') in the
27 computer's description field.
29 o Problems creating special file types from UNIX CIFS
30 clients and enabling 'unix extensions'.
33 New features introduced in this release include:
35 o Using a cups server other than localhost.
37 o Maintaining the service principal entry in the system
38 keytab for integration with other kerberized services.
39 Please refer to the 'use kerberos keytab' entry in
40 smb.conf(5). When using the heimdal kerberos libraries,
41 you must also specify the following in /etc/krb5.conf:
42 [libdefaults]
43 default_keytab_name = FILE:/etc/krb5.keytab
45 o Support for maintaining individual printer names
46 stored separately from the printer's sharename.

164 feature.
165 * Correctly honor the info level parameter in 'rpcclient
166 enumprinters'.
167 * Reintroduce 'force unknown acl user' parameter. When getting a
168 security descriptor for a file, if the owner sid is not known,

180 * Install libsmbclient into $(LIBDIR), not into hard coded
181 ${prefix}/lib. This helps amd64 systems with /lib and /lib64
182 and an explicit configure --libdir setting.
185 o <kawasa_r@itg.hitachi.co.jp>
186 * Memory leak fixes.
189 o Volker Lendecke <vl@samba.org>
190 * Fix DOS error code bug in reply_chkpath().

192 cli_samr_enum_als_groups; it is more like an account_control
193 field with individual bits what to retrieve.
194 * Implement 'net rpc group rename' -- rename domain groups.
195 * Implement the 'cups server' option. This makes it possible
196 to have virtual smbd's connect to different cups daemons.
197 * Paranoia fixes when adding local aliases to a user's NT_TOKEN.
198 * Fix sid_to_gid() calls in winbindd to prevent loops.

200 return.
201 * Make sure that the clients are given back the IP address to
202 which they connected in the case of a multi-homed host. Only
203 affects strings the spoolss printing replies.
204 * Fix the bad password lockout. This has not worked as pdb_ldap.c
205 did not ask for the modifyTimestamp attribute, so it could
206 not find it. Try not to regress by not putting that attrib
207 in the main list but append it manually for the relevant searches.
208 * Fix two memleaks in login_cache.c.
209 * fixes memory bloat when unmarshalling strings.
210 * Fix compile errors using gcc 3.2 on SuSE 8.2.

215 * Fix interaction between share security descriptor and the
216 'read only' smb.conf option.
217 * Fix bug that caused _samr_lookupsids() with more than 32 (
218 MAX_REF_DOMAINS) SIDs to fail.
221 o Herb Lewis <herb@samba.org>
222 * Fix errno tromping before calling iconv to reset the
223 conversion state.
224 * need to leave empty dacl so we can remove last ACE.
227 o Jianliang Lu <Jianliang.Lu@getronics.com>
228 * Reset the bad password count password counts upon a successful login.
231 o Joe Meadows "Joe Meadows" <jameadows@webopolis.com>
232 * Add optional timeout parameter to ldap open calls.

237 * BUG 1385: Don't use non-consts in a structure initialization.
240 o Stefan Metzmacher <metze@samba.org>
241 * print out the SVN revision by configure,
244 o Lars Mueller <lmuelle@suse.de>
245 * Fix afs related build issues on SuSE.
248 o Dan Peterson
249 * Implement NFS quota support on FreeBSD.
252 o Nick Wellnhofer <wellnhofer@aevum.de>
253 * Prevent lp_interfaces() list from being corrupted. Fixes
254 bug where nmbd would lose the list of network interfaces
255 on the system and consequently shutdown.
258 o James Wilkinson <jwilk@alumni.cse.ucsc.edu>
259 * Fix ntlm_auth memory leaks.
262 o Jelmer Vernooij <jelmer@samba.org>
263 * BUG 478: Rename vsnprintf to smb_vsnprintf so we don't
264 get duplicate symbol errors.
265 * Return an error when the last command read from stdin
266 fails in smbclient.
267 * Prepare for better error checking in tar.

275 =================================
276 Release Notes for Samba 3.0.5pre1
277 May 25, 2004
278 =================================
280 Common bugs fixed in this preview release include:
282 o Schannel failure in winbindd.
283 o Numerous memory leaks.
284 o Incompatibilities between the 'write list' and 'force user'
285 smb.conf options.
286 o Premature optimization of the open_directory() internal
287 function that broke tools such as the ArcServe backup
288 agent, Macromedia HomeSite, and Robocopy.
291 ATTENTION! NEW BEHAVIOR!
292 -------------------------
294 Beginning with Samba 3.0.5pre1, clients supporting the UNIX
295 extensions to the CIFS protocol can create symlinks to
296 absolute paths which will be **followed** by the server. This
297 functionality has been requested in order to correctly support
298 certain applications when the user's home directory is mounted
299 using some type of CIFS client (e.g. the cifsvfs in the Linux
300 2.6 kernel).
302 If this behavior is not acceptable for your production environment
303 you can set 'wide links = no' in the specific share declaration in
304 the server's smb.conf. Be aware that disabling wide link support
305 out of a share in Samba may impact the server's performance due
306 to the fact that smbd will now have to check each path additional
307 times before traversing it.

1001 Release Notes for Samba 3.0.2a
1002 February 13, 2004
1003 ==============================
1005 Samba 3.0.2a is a minor patch release for the 3.0.2 code base
1006 to address, in particular, a problem when using pdbedit to
1007 sanitize (--force-initialized-passwords) Samba's tdbsam
1008 backend. This is the latest stable release of Samba. This
1009 is the version that all production Samba servers should be
1010 running for all current bug-fixes.
1012 ******************* Attention! Achtung! Kree! *********************
1014 Beginning with Samba 3.0.2, passwords for accounts with a last
1015 change time (LCT-XXX in smbpasswd, sambaPwdLastSet attribute in
1016 ldapsam, etc...) of zero (0) will be regarded as uninitialized
1017 strings. This will cause authentication to fail for such
1018 accounts. If you have valid passwords that meet this criteria,
1019 you must update the last change time to a non-zero value. If you
1020 do not, then 'pdbedit --force-initialized-passwords' will disable
1021 these accounts and reset the password hashes to a string of X's.
1023 ******************* Attention! Achtung! Kree! *********************
1026 Changes since 3.0.2

1074 =============================
1075 Release Notes for Samba 3.0.2
1076 February 9, 2004
1077 =============================
1079 It has been confirmed that previous versions of Samba 3.0 are
1080 susceptible to a password initialization bug that could grant an
1081 attacker unauthorized access to a user account created by the
1082 mksmbpasswd.sh shell script.
1084 The Common Vulnerabilities and Exposures project (cve.mitre.org)
1085 has assigned the name CAN-2004-0082 to this issue.
1087 Samba administrators not wishing to upgrade to the current
1088 version should download the 3.0.2 release, build the pdbedit
1089 tool, and run
1091 root# pdbedit-3.0.2 --force-initialized-passwords
1093 This will disable all accounts not possessing a valid password
1094 (e.g. the password field has been set a string of X's).
1096 Samba servers running 3.0.2 are not vulnerable to this bug
1097 regardless of whether or not pdbedit has been used to sanitize
1098 the passdb backend.
1100 Some of the more visible bugs in 3.0.1 addressed in the 3.0.2
1101 release include:
1103 o Joining a Samba domain from Pre-SP2 Windows 2000 clients.
1104 o Logging onto a Samba domain from Windows XP clients.
1105 o Problems with the %U and %u smb.conf variables in relation to
1106 Windows 9x/ME clients.
1107 o Kerberos failures due to an invalid in memory keytab detection
1108 test.
1109 o Updates to the ntlm_auth tool.
1110 o Fixes for various SMB signing errors.
1111 o Better separation of WINS and DNS queries for domain controllers.
1112 o Issues with nss_winbind FreeBSD and Solaris.
1113 o Several crash bugs in smbd and winbindd.
1114 o Output formatting fixes for smbclient for better compatibility
1115 with scripts based on the 2.2 version.

1553 the local IP address to which a client connected.
1554 o Allow winbindd to match local accounts to domain SID when
1555 'winbind trusted domains only = yes' (bug 680).
1556 o Remove code in idmap_ldap that searches the user suffix and group
1557 suffix. It's not needed and provides inconsistent functionality
1558 from the tdb backend.
1559 o Patch to handle munged dial string for Windows 2000 TSE.
1560 Thanks to Gaz de France, Direction de la Recherche, Service
1561 Informatique Métier for their supporting this work by Aurelien
1562 Degrémont <adegremont@idealx.com>.
1563 o Correct the "smbldap_open: cannot access when not root error"
1564 messages when looking up group information (bug 281).

1592 know the winbindd pipe protocol.
1593 o Adds a variant of the winbindd_getgroups() call called
1594 winbindd_getusersids() that provides direct SID->SIDs listing of
1595 a users supplementary groups. This is enough to allow non-Samba
1596 applications to do ACL checking.
1597 o Make sure we don't append the 'ldap suffix' when writing out the
1598 'ldap XXX suffix' values in SWAT (bug 328).
1599 o Fix renames across file systems.
1600 o Ensure that items in a list of strings containing whitespace are
1601 written out surrounded by single quotes. This means that both
1602 double and single quotes are now used to surround strings in
1603 smb.conf (bug 481).
1604 o Enable SWAT to correctly determine if winbindd is running (bug
1605 398).

1617 authentication.
1618 o Change the name of the job passed off to cups from "Test Page"
1619 to "smbprn.00000033 Test Page" so that we can get the smb
1620 jobid back. This allow users to delete jobs with cups printing
1621 backend (partial work on bug 770).
1622 o Fix build of winbindd with static pdb modules.
1623 o Retrieve the correct ACL group bits if the file has an ACL
1624 (bug 802).
1625 o Implement "net rpc group members": Get members of a domain group
1626 in human-readable format.
1627 o Add MacOSX (Darwin) specific charset module code.
1628 o Use samr_dispinfo(level == 1) for enumerating domain users so we
1629 can include the full name in gecos field (bug 587).

1631 o Implement 'net rpc group list [global|local|builtin]*' for a
1632 select listing of the respective user databases.
1633 o Don't automatically set NT status code flag unless client tells
1634 us it can cope.
1635 o Add 'net status [sessions|shares] [parseable]'.
1636 o Don't mistake pre-existing UNIX jobs for smb jobs (remainder of
1637 bug 770).
1638 o Add 'Replicator' and 'RAS Servers' to list of builtin SIDs
1639 (bug 608).
1640 o Fix inverted logic in hosts allow/deny checks caused by
1641 s/strcmp/strequal/ (bug 846).
1642 o Implement correct version SamrRemoveSidForeignDomain() (bug 252).
1643 o Fix typo in 'hash' mangling algorithm.
1644 o Support munged dial for ldapsam (bug 800).
1645 o Fix process_incoming_data() to return the number of bytes handled
1646 this call whether we have a complete PDU or not; fixes bug
1647 with multiple PDU request rpc's broken over SMBwriteX calls
1648 each.
1649 o Fix incorrect smb flags2 for connections to pre-NT servers
1650 (causes smbclient to fail to OS2 for example) (bug 821).

1685 ######################################################################
1687 The original 3.0.0 release notes follow
1688 =======================================
1689 WHATS NEW IN Samba 3.0.0
1690 September 24, 2003
1691 =======================================
1694 Major new features:
1695 -------------------
1697 1) Active Directory support. Samba 3.0 is now able to
1698 join a ADS realm as a member server and authenticate
1699 users using LDAP/Kerberos.
1701 2) Unicode support. Samba will now negotiate UNICODE on the wire
1702 and internally there is now a much better infrastructure for
1703 multi-byte and UNICODE character sets.
1705 3) New authentication system. The internal authentication system
1706 has been almost completely rewritten. Most of the changes are
1707 internal, but the new auth system is also very configurable.
1709 4) New default filename mangling system.
1711 5) A new "net" command has been added. It is somewhat similar to
1712 the "net" command in windows. Eventually we plan to replace
1713 numerous other utilities (such as smbpasswd) with subcommands
1714 in "net".
1716 6) Samba now negotiates NT-style status32 codes on the wire. This
1717 improves error handling a lot.
1719 7) Better Windows 2000/XP/2003 printing support including publishing
1720 printer attributes in active directory.
1722 8) New loadable module support for passdb backends and character
1723 sets.
1725 9) New default dual-daemon winbindd support for better performance.
1727 10) Support for migrating from a Windows NT 4.0 domain to a Samba
1728 domain and maintaining user, group and domain SIDs.
1730 11) Support for establishing trust relationships with Windows NT 4.0
1731 domain controllers.
1733 12) Initial support for a distributed Winbind architecture using
1734 an LDAP directory for storing SID to uid/gid mappings.
1736 13) Major updates to the Samba documentation tree.
1738 14) Full support for client and server SMB signing to ensure
1739 compatibility with default Windows 2003 security settings.
1741 15) Improvement of ACL mapping features based on code donated by
1742 Andreas Grünbacher.
1745 Plus lots of other improvements!
1748 Additional Documentation
1749 ------------------------
1751 Please refer to Samba documentation tree (included in the docs/
1752 subdirectory) for extensive explanations of installing, configuring
1753 and maintaining Samba 3.0 servers and clients. It is advised to
1754 begin with the Samba-HOWTO-Collection for overviews and specific
1755 tasks (the current book is up to approximately 400 pages) and to
1756 refer to the various man pages for information on individual options.
1758 We are very glad to be able to include the second edition of
1759 "Using Samba" by Jay Ts, Robert Eckstein, and David Collier-Brown
1760 (O'Reilly & Associates) in this release. The book is available
1761 on-line at http://samba.org/samba/docs/ and is included with
1762 the Samba Web Administration Tool (SWAT). Thanks to the authors and
1763 publisher for making "Using Samba" under the GNU Free Documentation
1764 License.

1768 Upgrading from a previous Samba 3.0 beta
1769 ########################################
1771 Beginning with Samba 3.0.0beta3, the RID allocation functions
1772 have been moved into winbindd. Previously these were handled
1773 by each passdb backend. This means that winbindd must be running
1774 to automatically allocate RIDs for users and/or groups. Otherwise,
1775 smbd will use the 2.2 algorithm for generating new RIDs.
1777 If you are using 'passdb backend = tdbsam' with a previous Samba
1778 3.0 beta release (or possibly alpha), it may be necessary to
1779 move the RID_COUNTER entry from /usr/local/samba/private/passdb.tdb
1780 to winbindd_idmap.tdb. To do this:
1782 1) Ensure that winbindd_idmap.tdb exists (launch winbindd at least
1783 once)
1784 2) build tdbtool by executing 'make tdbtool' in the source/tdb/
1785 directory
1786 3) run: (note that 'tdb>' is the tool's prompt for input)
1788 root# ./tdbtool /usr/local/samba/private/passdb.tdb
1789 tdb> show RID_COUNTER
1790 key 12 bytes
1791 RID_COUNTER
1792 data 4 bytes
1793 [000] 0A 52 00 00 .R.
1795 tdb> move RID_COUNTER /usr/local/samba/var/locks/winbindd_idmap.tdb
1796 ....
1797 record moved
1799 If you are using 'passdb backend = ldapsam', it will be necessary to
1800 store idmap entries in the LDAP directory as well (i.e. idmap backend
1801 = ldap). Refer to the 'net idmap' command for more information on
1802 migrating SID<->UNIX id mappings from one backend to another.
1804 If the RID_COUNTER record does not exist, then these instructions are
1805 unneccessary and the new RID_COUNTER record will be correctly generated
1806 if needed.

1987 ${lock directory}/*tdb before upgrading to Samba 3.0. Samba will
1988 upgrade databases as they are opened (if necessary), but downgrading
1989 from 3.0 to 2.2 is an unsupported path.
1991 Name Description Backup?
1992 ---- ----------- -------
1993 account_policy User policy settings yes
1994 gencache Generic caching db no
1995 group_mapping Mapping table from Windows yes
1996 groups/SID to unix groups
1997 winbindd_idmap ID map table from SIDS to UNIX yes
1998 uids/gids.
1999 namecache Name resolution cache entries no
2000 netsamlogon_cache Cache of NET_USER_INFO_3 structure no
2001 returned as part of a successful
2002 net_sam_logon request
2003 printing/*.tdb Cached output from 'lpq no
2004 command' created on a per print
2005 service basis
2006 registry Read-only samba registry skeleton no
2007 that provides support for exporting
2008 various db tables via the winreg RPCs
2011 Changes in Behavior
2012 -------------------
2014 The following issues are known changes in behavior between Samba 2.2 and
2015 Samba 3.0 that may affect certain installations of Samba.
2017 1) When operating as a member of a Windows domain, Samba 2.2 would
2018 map any users authenticated by the remote DC to the 'guest account'
2019 if a uid could not be obtained via the getpwnam() call. Samba 3.0
2020 rejects the connection as NT_STATUS_LOGON_FAILURE. There is no
2021 current work around to re-establish the 2.2 behavior.
2023 2) When adding machines to a Samba 2.2 controlled domain, the
2024 'add user script' was used to create the UNIX identity of the
2025 machine trust account. Samba 3.0 introduces a new 'add machine
2026 script' that must be specified for this purpose. Samba 3.0 will
2027 not fall back to using the 'add user script' in the absence of
2028 an 'add machine script'
2031 ######################################################################
2032 Passdb Backends and Authentication
2033 ##################################
2035 There have been a few new changes that Samba administrators should be
2036 aware of when moving to Samba 3.0.
2038 1) encrypted passwords have been enabled by default in order to
2039 inter-operate better with out-of-the-box Windows client
2040 installations. This does mean that either (a) a samba account
2041 must be created for each user, or (b) 'encrypt passwords = no'
2042 must be explicitly defined in smb.conf.
2044 2) Inclusion of new 'security = ads' option for integration
2045 with an Active Directory domain using the native Windows
2046 Kerberos 5 and LDAP protocols.
2048 MIT kerberos 1.3.1 supports the ARCFOUR-HMAC-MD5 encryption
2049 type which is neccessary for servers on which the
2050 administrator password has not been changed, or kerberos-enabled
2051 SMB connections to servers that require Kerberos SMB signing.
2052 Besides this one difference, either MIT or Heimdal Kerberos
2053 distributions are usable by Samba 3.0.
2056 Samba 3.0 also includes the possibility of setting up chains
2057 of authentication methods (auth methods) and account storage
2058 backends (passdb backend). Please refer to the smb.conf(5)
2059 man page for details. While both parameters assume sane default
2060 values, it is likely that you will need to understand what the
2061 values actually mean in order to ensure Samba operates correctly.
2063 The recommended passdb backends at this time are
2065 * smbpasswd - 2.2 compatible flat file format
2066 * tdbsam - attribute rich database intended as an smbpasswd
2067 replacement for stand alone servers
2068 * ldapsam - attribute rich account storage and retrieval
2069 backend utilizing an LDAP directory.
2070 * ldapsam_compat - a 2.2 backward compatible LDAP account
2071 backend
2073 Certain functions of the smbpasswd(8) tool have been split between the
2074 new smbpasswd(8) utility, the net(8) tool, and the new pdbedit(8)
2075 utility. See the respective man pages for details.
2078 ######################################################################
2079 LDAP
2080 ####
2082 This section outlines the new features affecting Samba / LDAP
2083 integration.
2085 New Schema
2086 ----------
2088 A new object class (sambaSamAccount) has been introduced to replace
2089 the old sambaAccount. This change aids us in the renaming of
2090 attributes to prevent clashes with attributes from other vendors.
2091 There is a conversion script (examples/LDAP/convertSambaAccount) to
2092 modify and LDIF file to the new schema.
2094 Example:
2096 $ ldapsearch .... -b "ou=people,dc=..." > sambaAcct.ldif
2097 $ convertSambaAccount --sid=<Domain SID> \
2098 --input=sambaAcct.ldif --output=sambaSamAcct.ldif \
2099 --changetype=[modify|add]
2101 The <DOM SID> can be obtained by running 'net getlocalsid
2102 <DOMAINNAME>' on the Samba PDC as root. The changetype determines
2103 the format of the generated LDIF output--either create new entries
2104 or modify existing entries.
2106 The old sambaAccount schema may still be used by specifying the
2107 "ldapsam_compat" passdb backend. However, the sambaAccount and
2108 associated attributes have been moved to the historical section of
2109 the schema file and must be uncommented before use if needed.
2110 The 2.2 object class declaration for a sambaAccount has not changed
2111 in the 3.0 samba.schema file.
2113 Other new object classes and their uses include:
2115 * sambaDomain - domain information used to allocate rids
2116 for users and groups as necessary. The attributes are added
2117 in 'ldap suffix' directory entry automatically if
2118 an idmap uid/gid range has been set and the 'ldapsam'
2119 passdb backend has been selected.
2121 * sambaGroupMapping - an object representing the
2122 relationship between a posixGroup and a Windows
2123 group/SID. These entries are stored in the 'ldap
2124 group suffix' and managed by the 'net groupmap' command.
2126 * sambaUnixIdPool - created in the 'ldap idmap suffix' entry
2127 automatically and contains the next available 'idmap uid' and
2128 'idmap gid'
2130 * sambaIdmapEntry - object storing a mapping between a
2131 SID and a UNIX uid/gid. These objects are created by the
2132 idmap_ldap module as needed.
2134 * sambaSidEntry - object representing a SID alone, as a Structural
2135 class on which to build the sambaIdmapEntry.
2138 New Suffix for Searching
2139 ------------------------
2141 The following new smb.conf parameters have been added to aid in directing
2142 certain LDAP queries when 'passdb backend = ldapsam://...' has been
2143 specified.
2145 * ldap suffix - used to search for user and computer accounts
2146 * ldap user suffix - used to store user accounts
2147 * ldap machine suffix - used to store machine trust accounts
2148 * ldap group suffix - location of posixGroup/sambaGroupMapping entries
2149 * ldap idmap suffix - location of sambaIdmapEntry objects
2151 If an 'ldap suffix' is defined, it will be appended to all of the
2152 remaining sub-suffix parameters. In this case, the order of the suffix
2153 listings in smb.conf is important. Always place the 'ldap suffix' first
2154 in the list.
2156 Due to a limitation in Samba's smb.conf parsing, you should not surround
2157 the DN's with quotation marks.
2160 IdMap LDAP support
2161 ------------------
2163 Samba 3.0 supports an ldap backend for the idmap subsystem. The
2164 following options would inform Samba that the idmap table should be
2165 stored on the directory server onterose in the "ou=idmap,dc=plainjoe,
2166 dc=org" partition.
2168 [global]
2169 ...
2170 idmap backend = ldap:ldap://onterose/
2171 ldap idmap suffix = ou=idmap,dc=plainjoe,dc=org
2172 idmap uid = 40000-50000
2173 idmap gid = 40000-50000
2175 This configuration allows winbind installations on multiple servers to
2176 share a uid/gid number space, thus avoiding the interoperability problems
2177 with NFS that were present in Samba 2.2.
2181 ######################################################################
2182 Trust Relationships and a Samba Domain
2183 ######################################
2185 Samba 3.0.0beta2 is able to utilize winbindd as the means of
2186 allocating uids and gids to trusted users and groups. More
2187 information regarding Samba's support for establishing trust
2188 relationships can be found in the Samba-HOWTO-Collection included
2189 in the docs/ directory of this release.
2191 First create your Samba PDC and ensure that everything is
2192 working correctly before moving on the trusts.
2194 To establish Samba as the trusting domain (named SAMBA) from a Windows NT
2195 4.0 domain named WINDOWS:
2197 1) create the trust account for SAMBA in "User Manager for Domains"
2198 2) connect the trust from the Samba domain using
2199 'net rpc trustdom establish GLASS'
2201 To create a trustlationship with SAMBA as the trusted domain:
2203 1) create the initial trust account for GLASS using
2204 'smbpasswd -a -i GLASS'. You may need to create a UNIX
2205 account for GLASS$ prior to this step (depending on your
2206 local configuration).
2207 2) connect the trust from a WINDOWS DC using "User Manager
2208 for Domains"
2210 Now join winbindd on the Samba PDC to the SAMBA domain using
2211 the normal steps for adding a Samba server to an NT4 domain:
2212 (note that smbd & nmbd must be running at this point)
2214 root# net rpc join -U root
2215 Password: <enter root password from smbpasswd file here>
2217 Start winbindd and test the join with 'wbinfo -t'.
2219 Now test the trust relationship by connecting to the SAMBA DC
2220 (e.g. POGO) as a user from the WINDOWS domain:
2222 $ smbclient //pogo/netlogon -U Administrator -W WINDOWS
2223 Password:
2225 Now connect to the WINDOWS DC (e.g. CRYSTAL) as a Samba user:
2227 $ smbclient //crystal/netlogon -U root -W WINDOWS
2228 Password:
2230 ######################################################################
2231 Changes in Winbind
2232 ##################
2234 Beginning with Samba3.0.0beta3, winbindd has been given new account
2235 manage functionality equivalent to the 'add user script' family of
2236 smb.conf parameters. The idmap design has also been changed to
2237 centralize control of foreign SID lookups and matching to UNIX
2238 uids and gids.
2241 Brief Description of Changes
2242 ----------------------------
2244 1) The sid_to_uid() family of functions (smbd/uid.c) have been
2245 reverted to the 2.2.x design. This means that when resolving a
2246 SID to a UID or similar mapping:
2248 a) First consult winbindd
2249 b) perform a local lookup only if winbindd fails to
2250 return a successful answer
2252 There are some variations to this, but these two rules generally
2253 apply.
2255 2) All idmap lookups have been moved into winbindd. This means that
2256 a server must run winbindd (and support NSS) in order to achieve
2257 any mappings of SID to dynamically allocated UNIX ids. This was
2258 a conscious design choice.
2260 3) New functions have been added to winbindd to emulate the 'add user
2261 script' family of smbd functions without requiring that external
2262 scripts be defined. This functionality is controlled by the 'winbind
2263 enable local accounts' smb.conf parameter (enabled by default).
2265 However, this account management functionality is only supported
2266 in a local tdb (winbindd_idmap.tdb). If these new UNIX accounts
2267 must be shared among multiple Samba servers (such as a PDC and BDCs),
2268 it will be necessary to define your own 'add user script', et. al.
2269 programs that place the accounts/groups in some form of directory
2270 such as NIS or LDAP. This requirement was deemed beyond the scope
2271 of winbind's account management functions. Solutions for
2272 distributing UNIX system information have been deployed and tested
2273 for many years. We saw no need to reinvent the wheel.
2275 4) A member of a Samba controlled domain running winbindd is now able
2276 to map domain users directly onto existing UNIX accounts while still
2277 automatically creating accounts for trusted users and groups. This
2278 behavior is controlled by the 'winbind trusted domains only' smb.conf
2279 parameter (disabled by default to provide 2.2.x winbind behavior).
2281 5) Group mapping support is wrapped in the local_XX_to_XX() functions
2282 in smbd/uid.c. The reason that group mappings are not included
2283 in winbindd is because the purpose of Samba's group map is to
2284 match any Windows SID with an existing UNIX group. These UNIX
2285 groups can be created by winbindd (see next section), but the
2286 SID<->gid mapping is retreived by smbd, not winbindd.
2289 Examples
2290 --------
2292 * security = server running winbindd to allocate accounts on demand
2294 * Samba PDC running winbindd to handle the automatic creation of UNIX
2295 identities for machine trust accounts
2297 * Automtically creating UNIX user and groups when migrating a Windows NT
2298 4.0 PDC to a Samba PDC. Winbindd must be running when executing
2299 'net rpc vampire' for this to work.
