Work +on the SAMBA_3_0 CVS branch continues. Please refer to the section +on "Known Issues" for more details. + + +Major new features: +------------------- + +1) Active Directory support. 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. + + +###################################################################### +Changes since 3.0rc4 +#################### + +Please refer to the CVS log for the SAMBA_3_0 branch for complete +details: + +1) Fix bug that prevented restoring filenames of length + >100 characters. +2) Fix bug that prevented fast path code in strchr_m + from being used. +3) Make sure we store the desired access flag on incoming + SAMR rpc calls. +4) Fix smbd crash when dealing with mangled file names. +5) Ensure that the group comment field is not overwritten + if it already exists. +6) Fix bug that prevented 'net rpc join' from working + with mixed mode AD domains (bug 442). +7) Fix crash in smbd when a Samba PDC is not able to + enumerate trusted domains (bug 450). +8) Fix crash bug found by the Samba4 testsuite. +9) Fix bug that prevented smbd from returning an ACL list + if one of the SIDs could not be resolved (bug 470). +10) Remove -P option from smbclient printing scripts since it + has a different meaning in Samba 3.0 (bug 473). +11) Sync smbldap-tools with latest version +12) Cleanup some warnings produced by the Sun C compiler. +13) Several fixes for SWAT relating to international character + sets. + + +Changes since 3.0rc3 +#################### + +1) Fix incorrect error message in testparm.c regarding 'map system'. +2) Protect against core dump if ioctl for print job sends invalid + fid. +3) Fix bug in generic hash cacluation. +4) Remove references to unused 'strip dot' parameter +5) Fix CPU burn bug in multi-byte character conversion. +6) Use opt_target_workgroup instead of lp_workgroup() in vampire + code so we can override the value in smb.conf with the -w option. +7) Display an error if we can't create a posix account for the + user when running 'net rpc vampire' (bug 323). +8) Fix UTF8 conversion bugs in LDAP passdb and idmap code (bug 296). +9) Fix smbd crash when changing the machine trust account password + (bug 273). +10) Remove getpwnam() calls from init_sam_from_xxx(). This means + that %u & %g will no longer expand in the "login ..." set of + smb.conf options, but %U and %G still do. The payback is that + winbindd local accounts for users work with 'wbinfo -u' + when winbind is running on a Samba PDC. +11) Fix unitiailized timestamp where merging print_jobs and + lpq listing. +12) Fix bug in debian packaging files affecting non-i386 platforms. + + +Changes since 3.0rc2 +#################### + +1) Remove Perl module dependencies in generated RedHat 8/9 RPMS. +2) Update mount helper to take synonyms for file_mode and + dir_mode (fmask and dmask). +3) Fix portability bug with log2pcaphex. +4) Use different algorithm to generate codepages source code which + allows to take gaps into account thus making unnecessary + extended [index] = value, syntax in to_ucs2 array (bug 380). +5) Fix comment strings to 43 bytes as per spec. +6) Fix pam_winbind compile bug on FreeBSD (bug 261). +7) Support for in-memory keytabs, which are needed to make heimdal + work properly. MIT does not support them, so this check will be + used to decide whether to use them. (partial fix for bug 372). +8) Disable RC4-HMAC on broken heimdal setups. (remainder of bug + 372). +9) Correct bug in smbclient that resulted in errors when untarring + long filenames (bug 308). +10) Improve autoconf checks for PAM header files and libs. +11) Added fast path to convert_string() when dealing with + ASCII->ASCII, UCS2-LE->ASCII, and ASCII->UCS2-LE with + values <= 0x7F. +12) Quiet debug messages when we don't find a module and it is not + a critical error (bug 375). +13) Fix UNIX passwd sync properly. +14) Fix more transitive trust issues in winbindd (bug 305). +15) Ensure that winbindd functions with 'disable netbios = yes' +16) Store the real short domain name in secrets.tdb as soon as we + know it. Also display an error message when joining an AD + domain and the 'workgroup' parameter has not been specified. +17) Return 0 DFS links instead of -1 when dfs support is not enabled. +18) Update LDAP schema for Netscape DS 4.x and Novell eDirectory 8.7 +19) Ensure that name types can be specified using name#type notation + in the 'net' command (bug 73). +20) Add retry looks to ADS sequence number and domain SID lookups + (bug 364). +21) use a variant of alloc_sub_basic() for string lists such as + 'valid users', 'write list', and 'read list' (bug 397). +22) Fix seg fault when winbindd receives an error from the AD server + in response to an LDAP search (bug 282). +23) Update findsmb to use the new syntax for smbclient and nmblookup. +24) Fix bug that prevented variables from being used in explicitly + defined path in [homes]. +25) Only set SIDs when they're returned by the MySQL query + (pdb_mysql.so). +26) Include support for NTLMv2 key exchange. +27) Revert default for 'client ntlmv2 auth' to off (bug 359). +28) Fix crash in winbindd when the trust account password gets + changed underneath us via 'net rpc changetrustpw' (bug 382). +29) Use djb-algorithm string hash - faster than the tdb one we + used to use. Does not change on disk format or hashing location. +30) Implements some kind of improved AFS support for Samba on + Linux with OpenAFS 1.2.10. './configure --with-fake-kaserver' + assumes that you have OpenAFS on your machine. +31) When enumerating dfs shares loop from 0 to lp_numservices() instead + of relying on lp_servicename(n) to return an empty string for + invalid service numbers (bug 403). +32) Fix crash bug in 'net rpc samdump' (bug 334). +33) Fix crash bug in WINS NSS module (bug 299). +34) Fix a few minor compile errors on HP-UX. + + + +Changes since 3.0rc1 +#################### + +1) Add levels 261 and 262 to search.

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=..." > old.ldif + $ convertSambaAccount <DOM SID> old.ldif new.ldif + +The <DOM SID> can be obtained by running 'net getlocalsid <DOMAINNAME>' +on the Samba PDC as root. + +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.
