This is the version -that production Samba servers should be running for all -current bug-fixes. There have been several issues fixes since -the 3.0.4/5 release and new features have been added as well. -See the "Changes" section for details on exact updates. - -Common bugs fixed in 3.0.6 include: - - o Schannel failure in winbindd. - o Numerous memory leaks. - o Incompatibilities between the 'write list' and 'force user' - smb.conf options. - o Premature optimization of the open_directory() internal - function that broke tools such as the ArcServe backup - agent, Macromedia HomeSite, and Robocopy. - o Corrupt workgroup names in nmbd's browse.dat. - o Sharing violation errors commonly seen when opening - when serving Microsoft Office documents from a Samba - file share. - o Browsing problems caused by an apostrophe (') in the - computer's description field. - o Problems creating special file types from UNIX CIFS - clients and enabling 'unix extensions'. - o Fix stalls in smbd caused by inaccessible LDAP servers. - o Remove various memory leaks. - o Fix issues in the password lockout feature. - -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 -####### - -Changes since 3.0.6rc2 ----------------------- - -o Jeremy Allison <jra@samba.org> - * Ensure we return the same ACL revision on the wire that - W2K3 does. - * BUG 1578: Hardcode replacement for invalid characters as '_' - (based on fix from Alexander E.

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.

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.

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=<Domain SID> \ - --input=sambaAcct.ldif --output=sambaSamAcct.ldif \ - --changetype=[modify|add] - -The <DOM SID> can be obtained by running 'net getlocalsid -<DOMAINNAME>' 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: <enter root password from smbpasswd file here> - -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. This bugs should be released in an early - 3.0.x release. - -Please refer to https://bugzilla.samba.org/ for a current list of bugs -filed against the Samba 3.0 codebase. - - -###################################################################### -Reporting bugs & Development Discussion -####################################### - -Please discuss this release on the samba-technical mailing list or by -joining the #samba-technical IRC channel on irc.freenode.net. - -If you do report problems then please try to send high quality -feedback. If you don't provide vital information to help us track down -the problem then you will probably be ignored. - -A new bugzilla installation has been established to help support the -Samba 3.0 community of users.
