New features included in the 3.0.8 release are: o New migration functionality added the the net tool for files/directories, printers, and shares. o New experimental idmap backend for assigning uids/gids directly based on the user/group RID when acting as a member of single domain without any trusts. o Additional printer migration support for XP/2003 platforms. Change in Winbindd Behavior --------------------------- All usernames returned by winbindd are now converted to lower case for better consistency. This means any winbind installation relying on the winbind username will need to rename existing directories and/or files based on the username (%u and %U) to lower case (e.g. mv $name `echo $name | tr '[A-Z]' '[a-z]'`). This may include mail spool files, home directories, valid user lines in smb.conf, etc.... Change in Username Map ---------------------- Previous Samba releases would only support reading the fully qualified username (e.g. DOMAIN\user) from the username map when performing a kerberos login from a client. However, when looking up a map entry for a user authenticated by NTLM[SSP], only the login name would be used for matches. This resulted in inconsistent behavior sometimes even on the same server. Samba 3.0.8 obeys the following rules when applying the username map functionality: * When performing local authentication, the username map is applied to the login name before attempting to authenticate the connection. * When relying upon a external domain controller for validating authentication requests, smbd will apply the username map to the fully qualified username (i.e. DOMAIN\user) only after the user has been successfully authenticated. ###################################################################### Changes ####### Changes since 3.0.7 ------------------- smb.conf changes ---------------- Parameter Name Action -------------- ------ force printername New sendfile disabled by default commits ------- o Jeremy Allison * Ensure extended security bit is on only if we negotiated extended security. * Simplify statcache to use an in-memory tdb. * If you're selecting a hash algorithm for tdb, you need to do it at open time. * Removed old dir caching code - not being used now we have the statcache anyway. * Simplify the mangle hash code to use an in-memory tdb. * Merge iconv changes from Samba 4 branch. * Fix parsing of names ending in dot and a few other error returns. * BUG 1667: Smbpasswd file could be left locked on some error exits. * Fixes for smbclient tar functionality. * BUG 1743: Fix logic bug the deferred open code. * Don't try to set security descriptors on shares where this has been turned off. * Return correct error codes on old SEARCH call. * Ensure we set errno = E2BIG when we overflow in the fast-path character conversion code. * Fix the roundup problem (returning 1mb roundup) for non-Windows clients. * Added 'stat' command to smbclient to exercise the UNIX_FILE_BASIC info level. * Fix bug where we could incorrectly set sparse attribute. * Fix incorrect locks/unlocks in tdb_lockkeys()/tdb_unlockkeys() (reported by Taj Khattra ). * Remove locked keys tdb code. * BUG 1886: Prevent delete on close being set for readonly files (and return the correct error code). * Ensure we pass most of the new lock tests except for the cancel lock which is yet to be added (merged from Samba 4 branch). * BUG 1947: Fix incorrect use of getpwnam() etc. interface. * BUG 1956: Ensure errno is saved and restored consistently on a normal_close. * BUG 1651: Adapted patch from Nalin Dahyabhai for ensuring that all of the appropriate service principal names are set upon joining an AD domain. * Fix the correct use of resume name in the trans2 code. * BUG 1717: Adapted patch from Nalin Dahyabhai to detect the correct salt used when generated the DES key after joining an AD domain. * Enhanced krb5 detection routines in the autoconf scripts. o Andrew Bartlett * Avoid changing the machine account password in the passdb backend, when it has 'already been changed'.

New features introduced in this release include: O Support symlinks created by CIFS clients which can be followed on the server. o Using a cups server other than localhost. o Maintaining the service principal entry in the system keytab for integration with other kerberized services. Please refer to the 'use kerberos keytab' entry in smb.conf(5). When using the heimdal kerberos libraries, you must also specify the following in /etc/krb5.conf: [libdefaults] default_keytab_name = FILE:/etc/krb5.keytab o Support for maintaining individual printer names stored separately from the printer's sharename. o Support for maintaining user password history. o Support for honoring the logon times for user in a Samba domain. -------------------------------------------- unix extensions = yes (default) and symlinks -------------------------------------------- Beginning with Samba 3.0.6pre1 (formerly known as 3.0.5pre1), clients supporting the UNIX extensions to the CIFS protocol can create symlinks to absolute paths which will be **followed** by the server. This functionality has been requested in order to correctly support certain applications when the user's home directory is mounted using some type of CIFS client (e.g. the cifsvfs in the Linux 2.6 kernel). If this behavior is not acceptable for your production environment you can set 'wide links = no' in the specific share declaration in the server's smb.conf. Be aware that disabling wide link support out of a share in Samba may impact the server's performance due to the fact that smbd will now have to check each path additional times before traversing it. ------------------------ Password History Support ------------------------ The new password history feature allows smbd to check the new password in password change requests against a list of the user's previous passwords. The number of previous passwords to save can be set using pdbedit (4 in this example): root# pdbedit -P "password history" -C 4 When using the ldapsam passdb backend, it is vital to secure the following attributes from access by non-administrative users: * sambaNTPassword * sambaLMPassword * sambaPasswordHistory You should refer to your directory server's documentation on how to implement this restriction. Changes since 3.0.5 ------------------- smb.conf changes ---------------- Parameter Name Action -------------- ------ cups server New defer sharing violations New force unknown acl user New ldap timeout New printcap cache time New use kerberos keytab New commits ------- o Jeremy Allison * Correct path parsing bug that broke DeletePrinterDriverEx(). * Fix bugs in check_path_syntax() caught by asserts. * Internal change - rearrange internal global case setting variables to a per connection basis. * BUG 1345: Fix premature optimization in unix_convert(). * Allow clients to truncate a locked file. * BUG 1319: Always check to see if a user as write access to a share, even when 'force user' is set. * Fix specific case of open that doesn't cause oplock break, or share mode check. * Correct sid type is WKN_GROUP, not alias. Added some more known types (inspired by patch from Jianliang Lu). * Allow creation of absolute symlink paths via CIFS clients. * Fix charset bug in when invoking send_mailslot(). * When using widelinks = no, use realpath to canonicalize the connection path on connection create for the user. * Enhance stat open code. * Fix unix extensions mknod code path. * Allow unix domain socket creation via unix extensions. * Auto disable the 'store dos attribute' parameter if the underlying filesystem doesn't support EAs. * Implement deferred open code to fix a bug with Excel files on Samba shares. * BUG 1427: Catch bad path errors at the right point.

This is the version that production Samba servers should be running for all current bug-fixes. It has been confirmed that versions of Samba 3 prior to v3.0.4 are vulnerable to two potential buffer overruns. The individual details are given below. ------------- CAN-2004-0600 ------------- Affected Versions: Samba 3.0.2 and later The internal routine used by the Samba Web Administration Tool (SWAT v3.0.2 and later) to decode the base64 data during HTTP basic authentication is subject to a buffer overrun caused by an invalid base64 character. It is recommended that all Samba v3.0.2 or later installations running SWAT either (a) upgrade to v3.0.5, or (b) disable the swat administration service as a temporary workaround. This same code is used internally to decode the sambaMungedDial attribute value when using the ldapsam passdb backend. While we do not believe that the base64 decoding routines used by the ldapsam passdb backend can be exploited, sites using an LDAP directory service with Samba are strongly encouraged to verify that the DIT only allows write access to sambaSamAccount attributes by a sufficiently authorized user. The Samba Team would like to heartily thank Evgeny Demidov for analyzing and reporting this bug. ------------- CAN-2004-0686 ------------- Affected Versions: Samba 3.0.0 and later A buffer overrun has been located in the code used to support the 'mangling method = hash' smb.conf option. Please be aware that the default setting for this parameter is 'mangling method = hash2' and therefore not vulnerable. Affected Samba 3 installations can avoid this possible security bug by using the default hash2 mangling method. Server installations requiring the hash mangling method are encouraged to upgrade to Samba 3.0.5. ################################################################## -------------------------------------------------- ============================= Release Notes for Samba 3.0.4 May 8, 2004 ============================= Common bugs fixed in Samba 3.0.4 include: o Password changing after applying the patch described in the Microsoft KB828741 article to Windows clients. o Crashes in smbd. o Managing print jobs via Windows on Big-Endian servers. o Several memory leaks in winbindd and smbd. o Compile issues on AIX and *BSD.

This is the latest stable release of Samba. This is the version that all production Samba servers should be running for all current bug-fixes. ******************* Attention! Achtung! Kree! ********************* Beginning with Samba 3.0.2, passwords for accounts with a last change time (LCT-XXX in smbpasswd, sambaPwdLastSet attribute in ldapsam, etc...) of zero (0) will be regarded as uninitialized strings. This will cause authentication to fail for such accounts. If you have valid passwords that meet this criteria, you must update the last change time to a non-zero value. If you do not, then 'pdbedit --force-initialized-passwords' will disable these accounts and reset the password hashes to a string of X's. ******************* Attention! Achtung! Kree! ********************* Changes since 3.0.2 ------------------- commits ------- Please refer to the CVS log for the SAMBA_3_0 branch for complete details. The list of changes per contributor are as follows: o Jeremy Allison * Added paranoia checks in parsing code. o Andrew Bartlett * Ensure that changes to uninitialized passwords in ldapsam are written to the DIT. o Gerald (Jerry) Carter * Fixed iterator in tdbsam. * Fix bug that disabled accounts with a valid NT password hash, but no LanMan hash. o Steve French * Added missing nosetuid and noexec options. o Bostjan Golob * BUG 1046: Don't overwrite usernames of entries returned by getpwent_list(). o Sebastian Krahmer * Fixed potential crash bug in NTLMSSP parsing code. o Tim Potter * Fixed logic in tdb_brlock error checking. o Urban Widmark * Set nosuid,nodev flags in smbmnt by default. -------------------------------------------------- ============================= Release Notes for Samba 3.0.2 February 9, 2004 ============================= It has been confirmed that previous versions of Samba 3.0 are susceptible to a password initialization bug that could grant an attacker unauthorized access to a user account created by the mksmbpasswd.sh shell script. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0082 to this issue. Samba administrators not wishing to upgrade to the current version should download the 3.0.2 release, build the pdbedit tool, and run root# pdbedit-3.0.2 --force-initialized-passwords This will disable all accounts not possessing a valid password (e.g. the password field has been set a string of X's). Samba servers running 3.0.2 are not vulnerable to this bug regardless of whether or not pdbedit has been used to sanitize the passdb backend.

Samba 3.0 is now able to join a ADS realm as a member server and authenticate users using LDAP/Kerberos. 2) Unicode support. Samba will now negotiate UNICODE on the wire and internally there is now a much better infrastructure for multi-byte and UNICODE character sets. 3) New authentication system. The internal authentication system has been almost completely rewritten. Most of the changes are internal, but the new auth system is also very configurable. 4) New default filename mangling system. 5) A new "net" command has been added. It is somewhat similar to the "net" command in windows. Eventually we plan to replace numerous other utilities (such as smbpasswd) with subcommands in "net". 6) Samba now negotiates NT-style status32 codes on the wire. This improves error handling a lot. 7) Better Windows 2000/XP/2003 printing support including publishing printer attributes in active directory. 8) New loadable module support for passdb backends and character sets. 9) New default dual-daemon winbindd support for better performance. 10) Support for migrating from a Windows NT 4.0 domain to a Samba domain and maintaining user, group and domain SIDs. 11) Support for establishing trust relationships with Windows NT 4.0 domain controllers. 12) Initial support for a distributed Winbind architecture using an LDAP directory for storing SID to uid/gid mappings. 13) Major updates to the Samba documentation tree. 14) Full support for client and server SMB signing to ensure compatibility with default Windows 2003 security settings. 15) Improvement of ACL mapping features based on code donated by Andreas Grünbacher. Plus lots of other improvements! Additional Documentation ------------------------ Please refer to Samba documentation tree (included in the docs/ subdirectory) for extensive explanations of installing, configuring and maintaining Samba 3.0 servers and clients. It is advised to begin with the Samba-HOWTO-Collection for overviews and specific tasks (the current book is up to approximately 400 pages) and to refer to the various man pages for information on individual options. We are very glad to be able to include the second edition of "Using Samba" by Jay Ts, Robert Eckstein, and David Collier-Brown (O'Reilly & Associates) in this release. The book is available on-line at http://samba.org/samba/docs/ and is included with the Samba Web Administration Tool (SWAT). Thanks to the authors and publisher for making "Using Samba" under the GNU Free Documentation License. ###################################################################### Upgrading from a previous Samba 3.0 beta ######################################## Beginning with Samba 3.0.0beta3, the RID allocation functions have been moved into winbindd. Previously these were handled by each passdb backend. This means that winbindd must be running to automatically allocate RIDs for users and/or groups. Otherwise, smbd will use the 2.2 algorithm for generating new RIDs. If you are using 'passdb backend = tdbsam' with a previous Samba 3.0 beta release (or possibly alpha), it may be necessary to move the RID_COUNTER entry from /usr/local/samba/private/passdb.tdb to winbindd_idmap.tdb. To do this: 1) Ensure that winbindd_idmap.tdb exists (launch winbindd at least once) 2) build tdbtool by executing 'make tdbtool' in the source/tdb/ directory 3) run: (note that 'tdb>' is the tool's prompt for input) root# ./tdbtool /usr/local/samba/private/passdb.tdb tdb> show RID_COUNTER key 12 bytes RID_COUNTER data 4 bytes [000] 0A 52 00 00 .R. tdb> move RID_COUNTER /usr/local/samba/var/locks/winbindd_idmap.tdb .... record moved If you are using 'passdb backend = ldapsam', it will be necessary to store idmap entries in the LDAP directory as well (i.e. idmap backend = ldap). Refer to the 'net idmap' command for more information on migrating SID<->UNIX id mappings from one backend to another. If the RID_COUNTER record does not exist, then these instructions are unneccessary and the new RID_COUNTER record will be correctly generated if needed. ######################## Upgrading from Samba 2.2 ######################## This section is provided to help administrators understand the details involved with upgrading a Samba 2.2 server to Samba 3.0. Building -------- Many of the options to the GNU autoconf script have been modified in the 3.0 release. The most noticeable are: * removal of --with-tdbsam (is now included by default; see section on passdb backends and authentication for more details) * --with-ldapsam is now on used to provided backward compatible parameters for LDAP enabled Samba 2.2 servers. Refer to the passdb backend and authentication section for more details * inclusion of non-standard passdb modules may be enabled using --with-expsam. This includes an XML backend and a mysql backend. * removal of --with-msdfs (is now enabled by default) * removal of --with-ssl (no longer supported) * --with-utmp now defaults to 'yes' on supported systems * --with-sendfile-support is now enabled by default on supported systems Parameters ---------- This section contains a brief listing of changes to smb.conf options in the 3.0.0 release. Please refer to the smb.conf(5) man page for complete descriptions of new or modified parameters. Removed Parameters (order alphabetically): * admin log * alternate permissions * character set * client codepage * code page directory * coding system * domain admin group * domain guest group * force unknown acl user * hide local users * mangled stack * nt smb support * postscript * printer driver * printer driver file * printer driver location * read size * source environment * status * strip dot * total print jobs * use rhosts * valid chars * vfs options New Parameters (new parameters have been grouped by function): Remote management ----------------- * abort shutdown script * shutdown script User and Group Account Management --------------------------------- * add group script * add machine script * add user to group script * algorithmic rid base * delete group script * delete user from group script * passdb backend * set primary group script Authentication -------------- * auth methods * realm * passwd chat timeout Protocol Options ---------------- * client lanman auth * client NTLMv2 auth * client schannel * client signing * client use spnego * disable netbios * ntlm auth * paranoid server security * server schannel * server signing * smb ports * use spnego File Service ------------ * get quota command * hide special files * hide unwriteable files * hostname lookups * kernel change notify * mangle prefix * map acl inherit * msdfs proxy * set quota command * use sendfile * vfs objects Printing -------- * max reported print jobs UNICODE and Character Sets -------------------------- * display charset * dos charset * unicode * unix charset SID to uid/gid Mappings ----------------------- * idmap backend * idmap gid * idmap uid * winbind enable local accounts * winbind trusted domains only * template primary group * enable rid algorithm LDAP ---- * ldap delete dn * ldap group suffix * ldap idmap suffix * ldap machine suffix * ldap passwd sync * ldap replication sleep * ldap user suffix General Configuration --------------------- * preload modules * private dir Modified Parameters (changes in behavior): * encrypt passwords (enabled by default) * mangling method (set to 'hash2' by default) * passwd chat * passwd program * restrict anonymous (integer value) * security (new 'ads' value) * strict locking (enabled by default) * unix extensions (enabled by default) * winbind cache time (increased to 5 minutes) * winbind uid (deprecated in favor of 'idmap uid') * winbind gid (deprecated in favor of 'idmap gid') Databases --------- This section contains brief descriptions of any new databases introduced in Samba 3.0. Please remember to backup your existing ${lock directory}/*tdb before upgrading to Samba 3.0. Samba will upgrade databases as they are opened (if necessary), but downgrading from 3.0 to 2.2 is an unsupported path. Name Description Backup? ---- ----------- ------- account_policy User policy settings yes gencache Generic caching db no group_mapping Mapping table from Windows yes groups/SID to unix groups winbindd_idmap ID map table from SIDS to UNIX yes uids/gids. namecache Name resolution cache entries no netsamlogon_cache Cache of NET_USER_INFO_3 structure no returned as part of a successful net_sam_logon request printing/*.tdb Cached output from 'lpq no command' created on a per print service basis registry Read-only samba registry skeleton no that provides support for exporting various db tables via the winreg RPCs Changes in Behavior ------------------- The following issues are known changes in behavior between Samba 2.2 and Samba 3.0 that may affect certain installations of Samba. 1) When operating as a member of a Windows domain, Samba 2.2 would map any users authenticated by the remote DC to the 'guest account' if a uid could not be obtained via the getpwnam() call. Samba 3.0 rejects the connection as NT_STATUS_LOGON_FAILURE. There is no current work around to re-establish the 2.2 behavior. 2) When adding machines to a Samba 2.2 controlled domain, the 'add user script' was used to create the UNIX identity of the machine trust account. Samba 3.0 introduces a new 'add machine script' that must be specified for this purpose. Samba 3.0 will not fall back to using the 'add user script' in the absence of an 'add machine script' ###################################################################### Passdb Backends and Authentication ################################## There have been a few new changes that Samba administrators should be aware of when moving to Samba 3.0. 1) encrypted passwords have been enabled by default in order to inter-operate better with out-of-the-box Windows client installations. This does mean that either (a) a samba account must be created for each user, or (b) 'encrypt passwords = no' must be explicitly defined in smb.conf. 2) Inclusion of new 'security = ads' option for integration with an Active Directory domain using the native Windows Kerberos 5 and LDAP protocols. MIT kerberos 1.3.1 supports the ARCFOUR-HMAC-MD5 encryption type which is neccessary for servers on which the administrator password has not been changed, or kerberos-enabled SMB connections to servers that require Kerberos SMB signing. Besides this one difference, either MIT or Heimdal Kerberos distributions are usable by Samba 3.0. Samba 3.0 also includes the possibility of setting up chains of authentication methods (auth methods) and account storage backends (passdb backend). Please refer to the smb.conf(5) man page for details. While both parameters assume sane default values, it is likely that you will need to understand what the values actually mean in order to ensure Samba operates correctly. The recommended passdb backends at this time are * smbpasswd - 2.2 compatible flat file format * tdbsam - attribute rich database intended as an smbpasswd replacement for stand alone servers * ldapsam - attribute rich account storage and retrieval backend utilizing an LDAP directory. * ldapsam_compat - a 2.2 backward compatible LDAP account backend Certain functions of the smbpasswd(8) tool have been split between the new smbpasswd(8) utility, the net(8) tool, and the new pdbedit(8) utility. See the respective man pages for details. ###################################################################### LDAP #### This section outlines the new features affecting Samba / LDAP integration. New Schema ---------- A new object class (sambaSamAccount) has been introduced to replace the old sambaAccount. This change aids us in the renaming of attributes to prevent clashes with attributes from other vendors. There is a conversion script (examples/LDAP/convertSambaAccount) to modify and LDIF file to the new schema. Example: $ ldapsearch .... -b "ou=people,dc=..." > sambaAcct.ldif $ convertSambaAccount --sid= \ --input=sambaAcct.ldif --output=sambaSamAcct.ldif \ --changetype=[modify|add] The can be obtained by running 'net getlocalsid ' on the Samba PDC as root. The changetype determines the format of the generated LDIF output--either create new entries or modify existing entries. The old sambaAccount schema may still be used by specifying the "ldapsam_compat" passdb backend. However, the sambaAccount and associated attributes have been moved to the historical section of the schema file and must be uncommented before use if needed. The 2.2 object class declaration for a sambaAccount has not changed in the 3.0 samba.schema file. Other new object classes and their uses include: * sambaDomain - domain information used to allocate rids for users and groups as necessary. The attributes are added in 'ldap suffix' directory entry automatically if an idmap uid/gid range has been set and the 'ldapsam' passdb backend has been selected. * sambaGroupMapping - an object representing the relationship between a posixGroup and a Windows group/SID. These entries are stored in the 'ldap group suffix' and managed by the 'net groupmap' command. * sambaUnixIdPool - created in the 'ldap idmap suffix' entry automatically and contains the next available 'idmap uid' and 'idmap gid' * sambaIdmapEntry - object storing a mapping between a SID and a UNIX uid/gid. These objects are created by the idmap_ldap module as needed. * sambaSidEntry - object representing a SID alone, as a Structural class on which to build the sambaIdmapEntry. New Suffix for Searching ------------------------ The following new smb.conf parameters have been added to aid in directing certain LDAP queries when 'passdb backend = ldapsam://...' has been specified. * ldap suffix - used to search for user and computer accounts * ldap user suffix - used to store user accounts * ldap machine suffix - used to store machine trust accounts * ldap group suffix - location of posixGroup/sambaGroupMapping entries * ldap idmap suffix - location of sambaIdmapEntry objects If an 'ldap suffix' is defined, it will be appended to all of the remaining sub-suffix parameters. In this case, the order of the suffix listings in smb.conf is important. Always place the 'ldap suffix' first in the list. Due to a limitation in Samba's smb.conf parsing, you should not surround the DN's with quotation marks. IdMap LDAP support ------------------ Samba 3.0 supports an ldap backend for the idmap subsystem. The following options would inform Samba that the idmap table should be stored on the directory server onterose in the "ou=idmap,dc=plainjoe, dc=org" partition. [global] ... idmap backend = ldap:ldap://onterose/ ldap idmap suffix = ou=idmap,dc=plainjoe,dc=org idmap uid = 40000-50000 idmap gid = 40000-50000 This configuration allows winbind installations on multiple servers to share a uid/gid number space, thus avoiding the interoperability problems with NFS that were present in Samba 2.2. ###################################################################### Trust Relationships and a Samba Domain ###################################### Samba 3.0.0beta2 is able to utilize winbindd as the means of allocating uids and gids to trusted users and groups. More information regarding Samba's support for establishing trust relationships can be found in the Samba-HOWTO-Collection included in the docs/ directory of this release. First create your Samba PDC and ensure that everything is working correctly before moving on the trusts. To establish Samba as the trusting domain (named SAMBA) from a Windows NT 4.0 domain named WINDOWS: 1) create the trust account for SAMBA in "User Manager for Domains" 2) connect the trust from the Samba domain using 'net rpc trustdom establish GLASS' To create a trustlationship with SAMBA as the trusted domain: 1) create the initial trust account for GLASS using 'smbpasswd -a -i GLASS'. You may need to create a UNIX account for GLASS$ prior to this step (depending on your local configuration). 2) connect the trust from a WINDOWS DC using "User Manager for Domains" Now join winbindd on the Samba PDC to the SAMBA domain using the normal steps for adding a Samba server to an NT4 domain: (note that smbd & nmbd must be running at this point) root# net rpc join -U root Password: Start winbindd and test the join with 'wbinfo -t'. Now test the trust relationship by connecting to the SAMBA DC (e.g. POGO) as a user from the WINDOWS domain: $ smbclient //pogo/netlogon -U Administrator -W WINDOWS Password: Now connect to the WINDOWS DC (e.g. CRYSTAL) as a Samba user: $ smbclient //crystal/netlogon -U root -W WINDOWS Password: ###################################################################### Changes in Winbind ################## Beginning with Samba3.0.0beta3, winbindd has been given new account manage functionality equivalent to the 'add user script' family of smb.conf parameters. The idmap design has also been changed to centralize control of foreign SID lookups and matching to UNIX uids and gids. Brief Description of Changes ---------------------------- 1) The sid_to_uid() family of functions (smbd/uid.c) have been reverted to the 2.2.x design. This means that when resolving a SID to a UID or similar mapping: a) First consult winbindd b) perform a local lookup only if winbindd fails to return a successful answer There are some variations to this, but these two rules generally apply. 2) All idmap lookups have been moved into winbindd. This means that a server must run winbindd (and support NSS) in order to achieve any mappings of SID to dynamically allocated UNIX ids. This was a conscious design choice. 3) New functions have been added to winbindd to emulate the 'add user script' family of smbd functions without requiring that external scripts be defined. This functionality is controlled by the 'winbind enable local accounts' smb.conf parameter (enabled by default). However, this account management functionality is only supported in a local tdb (winbindd_idmap.tdb). If these new UNIX accounts must be shared among multiple Samba servers (such as a PDC and BDCs), it will be necessary to define your own 'add user script', et. al. programs that place the accounts/groups in some form of directory such as NIS or LDAP. This requirement was deemed beyond the scope of winbind's account management functions. Solutions for distributing UNIX system information have been deployed and tested for many years. We saw no need to reinvent the wheel. 4) A member of a Samba controlled domain running winbindd is now able to map domain users directly onto existing UNIX accounts while still automatically creating accounts for trusted users and groups. This behavior is controlled by the 'winbind trusted domains only' smb.conf parameter (disabled by default to provide 2.2.x winbind behavior). 5) Group mapping support is wrapped in the local_XX_to_XX() functions in smbd/uid.c. The reason that group mappings are not included in winbindd is because the purpose of Samba's group map is to match any Windows SID with an existing UNIX group. These UNIX groups can be created by winbindd (see next section), but the SID<->gid mapping is retreived by smbd, not winbindd. Examples -------- * security = server running winbindd to allocate accounts on demand * Samba PDC running winbindd to handle the automatic creation of UNIX identities for machine trust accounts * Automtically creating UNIX user and groups when migrating a Windows NT 4.0 PDC to a Samba PDC. Winbindd must be running when executing 'net rpc vampire' for this to work. ###################################################################### Known Issues ############ * There are several bugs currently logged against the 3.0 codebase that affect the use of NT 4.0 GUI domain management tools when run against a Samba 3.0 PDC.
