2 Release Notes for Samba 3.0.6
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 issues fixes since
9 the 3.0.4/5 release and new features have been added as well.
10 See the "Changes" section for details on exact updates.
12 Common bugs fixed in 3.0.6 include:
14 o Schannel failure in winbindd.
15 o Numerous memory leaks.
16 o Incompatibilities between the 'write list' and 'force user'
18 o Premature optimization of the open_directory() internal
19 function that broke tools such as the ArcServe backup
20 agent, Macromedia HomeSite, and Robocopy.
21 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
25 o Browsing problems caused by an apostrophe (') in the
26 computer's description field.
27 o Problems creating special file types from UNIX CIFS
28 clients and enabling 'unix extensions'.
29 o Fix stalls in smbd caused by inaccessible LDAP servers.
30 o Remove various memory leaks.
31 o Fix issues in the password lockout feature.
33 New features introduced in this release include:
35 O Support symlinks created by CIFS clients which
36 can be followed on the server.
37 o Using a cups server other than localhost.
38 o Maintaining the service principal entry in the system
39 keytab for integration with other kerberized services.
40 Please refer to the 'use kerberos keytab' entry in
41 smb.conf(5). When using the heimdal kerberos libraries,
42 you must also specify the following in /etc/krb5.conf:
44 default_keytab_name = FILE:/etc/krb5.keytab
45 o Support for maintaining individual printer names
46 stored separately from the printer's sharename.
47 o Support for maintaining user password history.
48 o Support for honoring the logon times for user in a
51 --------------------------------------------
52 unix extensions = yes (default) and symlinks
53 --------------------------------------------
55 Beginning with Samba 3.0.6pre1 (formerly known as 3.0.5pre1),
56 clients supporting the UNIX extensions to the CIFS protocol
57 can create symlinks to absolute paths which will be **followed**
58 by the server. This functionality has been requested in order
59 to correctly support certain applications when the user's home
60 directory is mounted using some type of CIFS client (e.g. the
61 cifsvfs in the Linux 2.6 kernel).
63 If this behavior is not acceptable for your production environment
64 you can set 'wide links = no' in the specific share declaration in
65 the server's smb.conf. Be aware that disabling wide link support
66 out of a share in Samba may impact the server's performance due
67 to the fact that smbd will now have to check each path additional
68 times before traversing it.
70 ------------------------
71 Password History Support
72 ------------------------
74 The new password history feature allows smbd to check the new
75 password in password change requests against a list of the user's
76 previous passwords. The number of previous passwords to save can
77 be set using pdbedit (4 in this example):
79 root# pdbedit -P "password history" -C 4
81 When using the ldapsam passdb backend, it is vital to secure the
82 following attributes from access by non-administrative users:
86 * sambaPasswordHistory
88 You should refer to your directory server's documentation on how
89 to implement this restriction.

537 Release Notes for Samba 3.0.5
539 =============================
541 Please note that Samba 3.0.5 is identical to Samba 3.0.4 with
542 the exception of correcting the two security issues outlined
545 ######################## SECURITY RELEASE ########################
547 Summary: Multiple Potential Buffer Overruns in Samba 3.0.x
548 CVE ID: CAN-2004-0600, CAN-2004-0686
549 (http://cve.mitre.org/)
552 This is the latest stable release of Samba. This is the version
553 that production Samba servers should be running for all current
556 It has been confirmed that versions of Samba 3 prior to v3.0.4
557 are vulnerable to two potential buffer overruns. The individual
558 details are given below.
564 Affected Versions: Samba 3.0.2 and later
566 The internal routine used by the Samba Web Administration
567 Tool (SWAT v3.0.2 and later) to decode the base64 data
568 during HTTP basic authentication is subject to a buffer
569 overrun caused by an invalid base64 character. It is
570 recommended that all Samba v3.0.2 or later installations
571 running SWAT either (a) upgrade to v3.0.5, or (b) disable
572 the swat administration service as a temporary workaround.
574 This same code is used internally to decode the
575 sambaMungedDial attribute value when using the ldapsam
576 passdb backend. While we do not believe that the base64
577 decoding routines used by the ldapsam passdb backend can
578 be exploited, sites using an LDAP directory service with
579 Samba are strongly encouraged to verify that the DIT only
580 allows write access to sambaSamAccount attributes by a
581 sufficiently authorized user.
583 The Samba Team would like to heartily thank Evgeny Demidov
584 for analyzing and reporting this bug.
590 Affected Versions: Samba 3.0.0 and later
592 A buffer overrun has been located in the code used to support
593 the 'mangling method = hash' smb.conf option. Please be aware
594 that the default setting for this parameter is 'mangling method
595 = hash2' and therefore not vulnerable.
597 Affected Samba 3 installations can avoid this possible security
598 bug by using the default hash2 mangling method. Server
599 installations requiring the hash mangling method are encouraged
600 to upgrade to Samba 3.0.5.

1175 Release Notes for Samba 3.0.2a
1177 ==============================
1179 Samba 3.0.2a is a minor patch release for the 3.0.2 code base
1180 to address, in particular, a problem when using pdbedit to
1181 sanitize (--force-initialized-passwords) Samba's tdbsam
1182 backend. This is the latest stable release of Samba. This
1183 is the version that all production Samba servers should be
1184 running for all current bug-fixes.
1186 ******************* Attention! Achtung! Kree! *********************
1188 Beginning with Samba 3.0.2, passwords for accounts with a last
1189 change time (LCT-XXX in smbpasswd, sambaPwdLastSet attribute in
1190 ldapsam, etc...) of zero (0) will be regarded as uninitialized
1191 strings. This will cause authentication to fail for such
1192 accounts. If you have valid passwords that meet this criteria,
1193 you must update the last change time to a non-zero value. If you
1194 do not, then 'pdbedit --force-initialized-passwords' will disable
1195 these accounts and reset the password hashes to a string of X's.
1197 ******************* Attention! Achtung! Kree! *********************
1206 Please refer to the CVS log for the SAMBA_3_0 branch for complete
1207 details. The list of changes per contributor are as follows:
1210 o Jeremy Allison <jra@samba.org>
1211 * Added paranoia checks in parsing code.
1214 o Andrew Bartlett <abartlet@samba.org>
1215 * Ensure that changes to uninitialized passwords in ldapsam
1216 are written to the DIT.
1219 o Gerald (Jerry) Carter <jerry@samba.org>
1220 * Fixed iterator in tdbsam.
1221 * Fix bug that disabled accounts with a valid NT password
1222 hash, but no LanMan hash.
1225 o Steve French <sfrench@us.ibm.com>
1226 * Added missing nosetuid and noexec options.
1229 o Bostjan Golob <golob@gimb.org>
1230 * BUG 1046: Don't overwrite usernames of entries returned
1234 o Sebastian Krahmer <krahmer@suse.de>

1248 =============================
1249 Release Notes for Samba 3.0.2
1251 =============================
1253 It has been confirmed that previous versions of Samba 3.0 are
1254 susceptible to a password initialization bug that could grant an
1255 attacker unauthorized access to a user account created by the
1256 mksmbpasswd.sh shell script.
1258 The Common Vulnerabilities and Exposures project (cve.mitre.org)
1259 has assigned the name CAN-2004-0082 to this issue.
1261 Samba administrators not wishing to upgrade to the current
1262 version should download the 3.0.2 release, build the pdbedit
1265 root# pdbedit-3.0.2 --force-initialized-passwords
1267 This will disable all accounts not possessing a valid password
1268 (e.g. the password field has been set a string of X's).
1270 Samba servers running 3.0.2 are not vulnerable to this bug
1271 regardless of whether or not pdbedit has been used to sanitize
1274 Some of the more visible bugs in 3.0.1 addressed in the 3.0.2
1277 o Joining a Samba domain from Pre-SP2 Windows 2000 clients.
1278 o Logging onto a Samba domain from Windows XP clients.
1279 o Problems with the %U and %u smb.conf variables in relation to
1280 Windows 9x/ME clients.
1281 o Kerberos failures due to an invalid in memory keytab detection
1283 o Updates to the ntlm_auth tool.
1284 o Fixes for various SMB signing errors.
1285 o Better separation of WINS and DNS queries for domain controllers.
1286 o Issues with nss_winbind FreeBSD and Solaris.
1287 o Several crash bugs in smbd and winbindd.
1288 o Output formatting fixes for smbclient for better compatibility
1289 with scripts based on the 2.2 version.

1861 The original 3.0.0 release notes follow
1862 =======================================
1863 WHATS NEW IN Samba 3.0.0
1865 =======================================
1871 1) Active Directory support. Samba 3.0 is now able to
1872 join a ADS realm as a member server and authenticate
1873 users using LDAP/Kerberos.
1875 2) Unicode support. Samba will now negotiate UNICODE on the wire
1876 and internally there is now a much better infrastructure for
1877 multi-byte and UNICODE character sets.
1879 3) New authentication system. The internal authentication system
1880 has been almost completely rewritten. Most of the changes are
1881 internal, but the new auth system is also very configurable.
1883 4) New default filename mangling system.
1885 5) A new "net" command has been added. It is somewhat similar to
1886 the "net" command in windows. Eventually we plan to replace
1887 numerous other utilities (such as smbpasswd) with subcommands
1890 6) Samba now negotiates NT-style status32 codes on the wire. This
1891 improves error handling a lot.
1893 7) Better Windows 2000/XP/2003 printing support including publishing
1894 printer attributes in active directory.
1896 8) New loadable module support for passdb backends and character
1899 9) New default dual-daemon winbindd support for better performance.
1901 10) Support for migrating from a Windows NT 4.0 domain to a Samba
1902 domain and maintaining user, group and domain SIDs.
1904 11) Support for establishing trust relationships with Windows NT 4.0
1907 12) Initial support for a distributed Winbind architecture using
1908 an LDAP directory for storing SID to uid/gid mappings.
1910 13) Major updates to the Samba documentation tree.
1912 14) Full support for client and server SMB signing to ensure
1913 compatibility with default Windows 2003 security settings.
1915 15) Improvement of ACL mapping features based on code donated by
1919 Plus lots of other improvements!
1922 Additional Documentation
1923 ------------------------
1925 Please refer to Samba documentation tree (included in the docs/
1926 subdirectory) for extensive explanations of installing, configuring
1927 and maintaining Samba 3.0 servers and clients. It is advised to
1928 begin with the Samba-HOWTO-Collection for overviews and specific
1929 tasks (the current book is up to approximately 400 pages) and to
1930 refer to the various man pages for information on individual options.
1932 We are very glad to be able to include the second edition of
1933 "Using Samba" by Jay Ts, Robert Eckstein, and David Collier-Brown
1934 (O'Reilly & Associates) in this release. The book is available
1935 on-line at http://samba.org/samba/docs/ and is included with
1936 the Samba Web Administration Tool (SWAT). Thanks to the authors and
1937 publisher for making "Using Samba" under the GNU Free Documentation
1941 ######################################################################
1942 Upgrading from a previous Samba 3.0 beta
1943 ########################################
1945 Beginning with Samba 3.0.0beta3, the RID allocation functions
1946 have been moved into winbindd. Previously these were handled
1947 by each passdb backend. This means that winbindd must be running
1948 to automatically allocate RIDs for users and/or groups. Otherwise,
1949 smbd will use the 2.2 algorithm for generating new RIDs.
1951 If you are using 'passdb backend = tdbsam' with a previous Samba
1952 3.0 beta release (or possibly alpha), it may be necessary to
1953 move the RID_COUNTER entry from /usr/local/samba/private/passdb.tdb
1954 to winbindd_idmap.tdb. To do this:
1956 1) Ensure that winbindd_idmap.tdb exists (launch winbindd at least
1958 2) build tdbtool by executing 'make tdbtool' in the source/tdb/
1960 3) run: (note that 'tdb>' is the tool's prompt for input)
1962 root# ./tdbtool /usr/local/samba/private/passdb.tdb
1963 tdb> show RID_COUNTER
1967 [000] 0A 52 00 00 .R.
1969 tdb> move RID_COUNTER /usr/local/samba/var/locks/winbindd_idmap.tdb
1973 If you are using 'passdb backend = ldapsam', it will be necessary to
1974 store idmap entries in the LDAP directory as well (i.e. idmap backend
1975 = ldap). Refer to the 'net idmap' command for more information on
1976 migrating SID<->UNIX id mappings from one backend to another.
1978 If the RID_COUNTER record does not exist, then these instructions are
1979 unneccessary and the new RID_COUNTER record will be correctly generated

2159 This section contains brief descriptions of any new databases
2160 introduced in Samba 3.0. Please remember to backup your existing
2161 ${lock directory}/*tdb before upgrading to Samba 3.0. Samba will
2162 upgrade databases as they are opened (if necessary), but downgrading
2163 from 3.0 to 2.2 is an unsupported path.
2165 Name Description Backup?
2166 ---- ----------- -------
2167 account_policy User policy settings yes
2168 gencache Generic caching db no
2169 group_mapping Mapping table from Windows yes
2170 groups/SID to unix groups
2171 winbindd_idmap ID map table from SIDS to UNIX yes
2173 namecache Name resolution cache entries no
2174 netsamlogon_cache Cache of NET_USER_INFO_3 structure no
2175 returned as part of a successful

2177 printing/*.tdb Cached output from 'lpq no
2178 command' created on a per print
2180 registry Read-only samba registry skeleton no
2181 that provides support for exporting
2182 various db tables via the winreg RPCs
2188 The following issues are known changes in behavior between Samba 2.2 and
2189 Samba 3.0 that may affect certain installations of Samba.
2191 1) When operating as a member of a Windows domain, Samba 2.2 would
2192 map any users authenticated by the remote DC to the 'guest account'
2193 if a uid could not be obtained via the getpwnam() call. Samba 3.0
2194 rejects the connection as NT_STATUS_LOGON_FAILURE. There is no
2195 current work around to re-establish the 2.2 behavior.
2197 2) When adding machines to a Samba 2.2 controlled domain, the
2198 'add user script' was used to create the UNIX identity of the
2199 machine trust account. Samba 3.0 introduces a new 'add machine
2200 script' that must be specified for this purpose. Samba 3.0 will
2201 not fall back to using the 'add user script' in the absence of
2202 an 'add machine script'
2205 ######################################################################
2206 Passdb Backends and Authentication
2207 ##################################
2209 There have been a few new changes that Samba administrators should be
2210 aware of when moving to Samba 3.0.
2212 1) encrypted passwords have been enabled by default in order to
2213 inter-operate better with out-of-the-box Windows client
2214 installations. This does mean that either (a) a samba account
2215 must be created for each user, or (b) 'encrypt passwords = no'
2216 must be explicitly defined in smb.conf.
2218 2) Inclusion of new 'security = ads' option for integration
2219 with an Active Directory domain using the native Windows
2220 Kerberos 5 and LDAP protocols.
2222 MIT kerberos 1.3.1 supports the ARCFOUR-HMAC-MD5 encryption
2223 type which is neccessary for servers on which the
2224 administrator password has not been changed, or kerberos-enabled
2225 SMB connections to servers that require Kerberos SMB signing.
2226 Besides this one difference, either MIT or Heimdal Kerberos
2227 distributions are usable by Samba 3.0.
2230 Samba 3.0 also includes the possibility of setting up chains
2231 of authentication methods (auth methods) and account storage
2232 backends (passdb backend). Please refer to the smb.conf(5)
2233 man page for details. While both parameters assume sane default
2234 values, it is likely that you will need to understand what the
2235 values actually mean in order to ensure Samba operates correctly.
2237 The recommended passdb backends at this time are
2239 * smbpasswd - 2.2 compatible flat file format
2240 * tdbsam - attribute rich database intended as an smbpasswd
2241 replacement for stand alone servers
2242 * ldapsam - attribute rich account storage and retrieval
2243 backend utilizing an LDAP directory.
2244 * ldapsam_compat - a 2.2 backward compatible LDAP account
2247 Certain functions of the smbpasswd(8) tool have been split between the
2248 new smbpasswd(8) utility, the net(8) tool, and the new pdbedit(8)
2249 utility. See the respective man pages for details.
2252 ######################################################################
2256 This section outlines the new features affecting Samba / LDAP
2262 A new object class (sambaSamAccount) has been introduced to replace
2263 the old sambaAccount. This change aids us in the renaming of
2264 attributes to prevent clashes with attributes from other vendors.
2265 There is a conversion script (examples/LDAP/convertSambaAccount) to
2266 modify and LDIF file to the new schema.
2270 $ ldapsearch .... -b "ou=people,dc=..." > sambaAcct.ldif
2271 $ convertSambaAccount --sid=<Domain SID> \
2272 --input=sambaAcct.ldif --output=sambaSamAcct.ldif \
2273 --changetype=[modify|add]
2275 The <DOM SID> can be obtained by running 'net getlocalsid
2276 <DOMAINNAME>' on the Samba PDC as root. The changetype determines
2277 the format of the generated LDIF output--either create new entries
2278 or modify existing entries.
2280 The old sambaAccount schema may still be used by specifying the
2281 "ldapsam_compat" passdb backend. However, the sambaAccount and
2282 associated attributes have been moved to the historical section of
2283 the schema file and must be uncommented before use if needed.
2284 The 2.2 object class declaration for a sambaAccount has not changed
2285 in the 3.0 samba.schema file.
2287 Other new object classes and their uses include:
2289 * sambaDomain - domain information used to allocate rids
2290 for users and groups as necessary. The attributes are added
2291 in 'ldap suffix' directory entry automatically if
2292 an idmap uid/gid range has been set and the 'ldapsam'
2293 passdb backend has been selected.
2295 * sambaGroupMapping - an object representing the
2296 relationship between a posixGroup and a Windows
2297 group/SID. These entries are stored in the 'ldap
2298 group suffix' and managed by the 'net groupmap' command.
2300 * sambaUnixIdPool - created in the 'ldap idmap suffix' entry
2301 automatically and contains the next available 'idmap uid' and
2304 * sambaIdmapEntry - object storing a mapping between a
2305 SID and a UNIX uid/gid. These objects are created by the
2306 idmap_ldap module as needed.
2308 * sambaSidEntry - object representing a SID alone, as a Structural
2309 class on which to build the sambaIdmapEntry.
2312 New Suffix for Searching
2313 ------------------------
2315 The following new smb.conf parameters have been added to aid in directing
2316 certain LDAP queries when 'passdb backend = ldapsam://...' has been
2319 * ldap suffix - used to search for user and computer accounts
2320 * ldap user suffix - used to store user accounts
2321 * ldap machine suffix - used to store machine trust accounts
2322 * ldap group suffix - location of posixGroup/sambaGroupMapping entries
2323 * ldap idmap suffix - location of sambaIdmapEntry objects
2325 If an 'ldap suffix' is defined, it will be appended to all of the
2326 remaining sub-suffix parameters. In this case, the order of the suffix
2327 listings in smb.conf is important. Always place the 'ldap suffix' first
2330 Due to a limitation in Samba's smb.conf parsing, you should not surround
2331 the DN's with quotation marks.
2337 Samba 3.0 supports an ldap backend for the idmap subsystem. The
2338 following options would inform Samba that the idmap table should be
2339 stored on the directory server onterose in the "ou=idmap,dc=plainjoe,
2344 idmap backend = ldap:ldap://onterose/
2345 ldap idmap suffix = ou=idmap,dc=plainjoe,dc=org
2346 idmap uid = 40000-50000
2347 idmap gid = 40000-50000
2349 This configuration allows winbind installations on multiple servers to
2350 share a uid/gid number space, thus avoiding the interoperability problems
2351 with NFS that were present in Samba 2.2.
2355 ######################################################################
2356 Trust Relationships and a Samba Domain
2357 ######################################
2359 Samba 3.0.0beta2 is able to utilize winbindd as the means of
2360 allocating uids and gids to trusted users and groups. More
2361 information regarding Samba's support for establishing trust
2362 relationships can be found in the Samba-HOWTO-Collection included
2363 in the docs/ directory of this release.
2365 First create your Samba PDC and ensure that everything is
2366 working correctly before moving on the trusts.
2368 To establish Samba as the trusting domain (named SAMBA) from a Windows NT
2369 4.0 domain named WINDOWS:
2371 1) create the trust account for SAMBA in "User Manager for Domains"
2372 2) connect the trust from the Samba domain using
2373 'net rpc trustdom establish GLASS'
2375 To create a trustlationship with SAMBA as the trusted domain:
2377 1) create the initial trust account for GLASS using
2378 'smbpasswd -a -i GLASS'. You may need to create a UNIX
2379 account for GLASS$ prior to this step (depending on your
2380 local configuration).
2381 2) connect the trust from a WINDOWS DC using "User Manager
2384 Now join winbindd on the Samba PDC to the SAMBA domain using
2385 the normal steps for adding a Samba server to an NT4 domain:
2386 (note that smbd & nmbd must be running at this point)
2388 root# net rpc join -U root
2389 Password: <enter root password from smbpasswd file here>
2391 Start winbindd and test the join with 'wbinfo -t'.
2393 Now test the trust relationship by connecting to the SAMBA DC
2394 (e.g. POGO) as a user from the WINDOWS domain:
2396 $ smbclient //pogo/netlogon -U Administrator -W WINDOWS
2399 Now connect to the WINDOWS DC (e.g. CRYSTAL) as a Samba user:
2401 $ smbclient //crystal/netlogon -U root -W WINDOWS
2404 ######################################################################
2408 Beginning with Samba3.0.0beta3, winbindd has been given new account
2409 manage functionality equivalent to the 'add user script' family of
2410 smb.conf parameters. The idmap design has also been changed to
2411 centralize control of foreign SID lookups and matching to UNIX
2415 Brief Description of Changes
2416 ----------------------------
2418 1) The sid_to_uid() family of functions (smbd/uid.c) have been
2419 reverted to the 2.2.x design. This means that when resolving a
2420 SID to a UID or similar mapping:
2422 a) First consult winbindd
2423 b) perform a local lookup only if winbindd fails to
2424 return a successful answer
2426 There are some variations to this, but these two rules generally
2429 2) All idmap lookups have been moved into winbindd. This means that
2430 a server must run winbindd (and support NSS) in order to achieve
2431 any mappings of SID to dynamically allocated UNIX ids. This was
2432 a conscious design choice.
2434 3) New functions have been added to winbindd to emulate the 'add user
2435 script' family of smbd functions without requiring that external
2436 scripts be defined. This functionality is controlled by the 'winbind
2437 enable local accounts' smb.conf parameter (enabled by default).
2439 However, this account management functionality is only supported
2440 in a local tdb (winbindd_idmap.tdb). If these new UNIX accounts
2441 must be shared among multiple Samba servers (such as a PDC and BDCs),
2442 it will be necessary to define your own 'add user script', et. al.
2443 programs that place the accounts/groups in some form of directory
2444 such as NIS or LDAP. This requirement was deemed beyond the scope
2445 of winbind's account management functions. Solutions for
2446 distributing UNIX system information have been deployed and tested
2447 for many years. We saw no need to reinvent the wheel.
2449 4) A member of a Samba controlled domain running winbindd is now able
2450 to map domain users directly onto existing UNIX accounts while still
2451 automatically creating accounts for trusted users and groups. This
2452 behavior is controlled by the 'winbind trusted domains only' smb.conf
2453 parameter (disabled by default to provide 2.2.x winbind behavior).
2455 5) Group mapping support is wrapped in the local_XX_to_XX() functions
2456 in smbd/uid.c. The reason that group mappings are not included
2457 in winbindd is because the purpose of Samba's group map is to
2458 match any Windows SID with an existing UNIX group. These UNIX
2459 groups can be created by winbindd (see next section), but the
2460 SID<->gid mapping is retreived by smbd, not winbindd.
2466 * security = server running winbindd to allocate accounts on demand
2468 * Samba PDC running winbindd to handle the automatic creation of UNIX
2469 identities for machine trust accounts
2471 * Automtically creating UNIX user and groups when migrating a Windows NT
2472 4.0 PDC to a Samba PDC. Winbindd must be running when executing
2473 'net rpc vampire' for this to work.
