+these beta releases, and to provide high quality feedback on what
+needs fixing.
+
+Samba 3.0 is feature complete. However there is still some final
+work to be done on certain pieces of functionality. Please refer to
+the section on "Known Issues" for more details.
-Note that Samba 3.0 is not feature complete yet. There is a more

-widely tested we will have a hard time doing a stable release in a
-reasonable time frame.
Major new features:
-------------------
-- Active Directory support. This release is able to join a ADS realm
- as a member server and authenticate users using LDAP/kerberos.
-
-- 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.
-
-- 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.
-
-- new filename mangling system. The filename mangling system has been
- completely rewritten. An internal database now stores mangling maps
- persistently. This needs lots of testing.
-
-- new "net" command. A new "net" command has been added. It is
- somewhat similar to the "net" command in windows. Eventually we plan
- to replace a bunch of other utilities (such as smbpasswd) with
- subcommands in "net", at the moment only a few things are
- implemented.

+Changes since 3.0beta2
+######################
+
+Please refer to the CVS log for the SAMBA_3_0 branch for complete
+details
+
+1) Added fix for Japanese case names in statcache code;
+ these can change size on upper casing.
+2) Correct issues with iconv detection in configure script
+ (support needed to find iconv libraries on FreeBSD).
+3) Fix bug that caused a WINS server to be marked as dead
+ incorrectly (bug #190).
+4) Removing additional deadlocks conditions that prevented
+ winbindd from running on a Samba PDC (used for trust
+ relationships).
+5) Add support for searching for Active Directory for
+ published printers (net ads printer search).
+6) Separate UNIX username from DOMAIN\username in pipe
+ credentials.
+7) Auth modules now support returning NT_STATUS_NOT_IMPLEMENTED
+ for cases that they cannot handle.
+8) Flush winbindd connection cache when the machine trust account
+ password is changed while a connection is open (bug #200).

+27) Add support to nmbd and winbindd for 'smbcontrol <pid>
+ reload-config'.
+28) Correct problem with smbtar when dealing with files > 8Gb
+ (bug #102).
+
+
+
+Changes since 3.0beta1
+######################
+
+1) Rework our smb signing code again, this factors out some of
+ the common MAC calculation code, and now supports multiple
+ outstanding packets (bug #40).

+ failures.
+5) Fix bug when aliased 'winbind uid/gid' parameters are used.
+ ('winbind uid/gid' are now replaced with 'idmap uid/gid').
+6) Added an auth flag that indicates if we should be allowed
+ to fall back to NTLMSSP for SASL if krb5 fails.
+7) Fixed the bug that forced us not to use the winbindd cache when
+ we have a primary ADS domain and a secondary (trusted) NT4
+ domain.

+14) Add trivial extension to 'net' to dump current local idmap
+ and restore mappings as well.
+15) Modify 'net rpc vampire' to add new and existing users to
+ both the idmap and the SAM. This code needs further testing.
+16) Fix crash bug in ADS searches.
+17) Build libnss_wins.so as part of nsswitch target (bug #160).
+18) Make net rpc vampire return an error if the sam sync RPC
+ returns an error.
+19) Fail to join an NT 4 domain as a BDC if a workstation account
+ using our name exists.
+20) Fix various memory leaks in server and client code
+21) Remove the short option to --set-auth-user for wbinfo (-A) to
+ prevent confusion with the -a option (bug #158).

+ ( if you installed beta1, be sure to
+ 'mv idmap.tdb winbindd_idmap.tdb' ).
+35) Fix pdb_ldap segfaults, and wrong default values for
+ ldapsam_compat.
+36) Enable negative connection cache for winbindd's ADS backend
+ functions.
+37) Enable address caching for active directory DC's so we don't
+ have to hit DNS so much.
+38) Fix bug in idmap code that caused mapping to randomly be
+ redefined.
+39) Add tdb locking code to prevent race condition when adding a
+ new mapping to idmap.
+40) Fix 'map to guest = bad user' when acting as a PDC supporting
+ trust relationships.
+41) Prevent deadlock issues when running winbindd on a Samba PDC
+ to handle allocating uids & gids for trusted users and groups
+42) added LOCALE patch from Steve Langasek (bug #122).
+43) Add the 'guest' passdb backend automatically to the end of
+ the 'passdb backend' list if 'guest account' has a valid
+ username.
+44) Remove samstrict_dc auth method. Rework 'samstrict' to only
+ handle our local names (or domain name if we are a PDC).
+ Move existing permissive 'sam' method to 'sam_ignoredomain'
+ and make 'samstrict' the new default 'sam' auth method.
+45) Match Windows NT4/2k behavior when authenticating a user with
+ and unknown domain (default to our domain if we are a DC or
+ domain member; default to our local name if we are a
+ standalone server).
+46) Fix Get_Pwnam() to always fall back to lookup 'user' if the
+ 'DOMAIN\user' lookup fails. This matches 2.2. behavior.
+47) Fix the trustdom_cache code to update the list of trusted
+ domains when operating as a domain member and not using
+ winbindd.
+48) Remove 'nisplussam' passdb backend since it has suffered for
+ too long without a maintainer.

+######################################################################
+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.

+${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
+-------------------
-- new dual-daemon winbindd support for better performance
+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.
+
+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:
-- support for migrating from a Windows NT 4.0 domain
+ $ smbclient //crystal/netlogon -U root -W WINDOWS
+ Password:
-- support for establishing trust relationships with Windows NT 4.0
- domain controllers
+######################################################################
+Changes in Winbind
+##################
-Plus lots of other changes!
+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
+----------------------------
-Please discuss this release on the samba-technical mailing list or by
-joining the #samba-technical IRC channel on irc.freenode.net.
+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:
-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) 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.
-Changes in alpha23:
--------------------
+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.
- LDAP Group Mapping
- ------------------
+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).
- pdbedit -i -e sets all SAM_ACCOUNT elements to CHANGED to
- satisfy the new pdb_ldap.c handling. pdbedit -g transfers group
- mappings. I made this separate from the user database, as current
- installations have to live with a split backend. So, if you are
- running 3_0 alphas with LDAP as a backend and upgrade to 3.0alpha23,
- you must call
+ 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.
- root# pdbedit -i tdbsam -e ldapsam -g
+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).
- to transfer your group mapping database to LDAP.
+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.
- All groups must be represented as posixGroup objects in
- the directory and you must adapt your LDAP schema to support the
- sambaGroupMapping before running this command. Refer to
- examples/LDAP/samba.schema for details on the objectclass.
+Examples
+--------
- Parameters
- ----------
+* security = server running winbindd to allocate accounts on demand
- Modified Parameters (see smb.conf(5) for details):
+* Samba PDC running winbindd to handle the automatic creation of UNIX
+ identities for machine trust accounts
- * passdb backend
+* 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.
- Added Parameters

+Known Issues
+############
- * ldap del only sam attr
- * ldap delete dn
+* The smbldap perl scripts for managing user entries in an LDAP
+ directory have not be updated to function with the Samba 3.0
+ schema changes. This (or an equivalent solution) work is planned
+ to be completed prior to the stable 3.0.0 release.
+Please refer to https://bugzilla.samba.org/ for a current list of bugs
+filed against the Samba 3.0 codebase.
- ChangeLog
- ---------
-
- See cvs log for SAMBA_3_0 for complete details. There are many
- smaller numerous changes that would clutter the release notes.
-
-0) Include security fix from Samba 2.2.8
-1) Fix interop bug in tconX on port 445 with Windows 2000
-2) Interpret missing SMB_ACL_USER_OBJ, SMB_ACL_GROUP_OBJ, or
- SMB_ACL_OTHER as "preserve current value" instead of attempting
- to build one ourself.
-3) Rearrange set_nt_acl() such that chown is only done before
- setting ACLs if there is either no change of owning user, or
- change of owning user is towards the current user. Otherwise
- chown is done after setting ACLs.
-4) Continuing work on NTLMSSP-based SMB signing
-5) When opening an existing TDB, don't require the hash_size
- specified to the open call to be the same as that of the
- existing tdb. The specified hash_size is only used if the
- tdb needs to be (re)created.
-6) Add support for "WinXP" and "Win2K3" client architectures.
-7) Fixed the unmarshalling of the queryaliasmem SAMR call
-8) Windows 2000 can take much longer than the specified time to
- respond to a lock - so to make the torture tests valid I give
- it a grace time of 10 seconds instead of 2
-9) Continued work on string handling paranoia
-10) Merge new statcache.c from HEAD
-11) Add new 'net ads dn' option
-12) Sync up SessionSetup code to HEAD, including Luke Howard's
- session key and auth verifier patches
-13) Work on cleaning up winbindd's mutex locking
-14) Add support for LDAP based Windows group mapping
-15) Improve LDAP update routines
-16) Fix memory leaks found by Valgrind
-17) Add a 'privileged' mode to Winbindd
-18) Work around platforms that have broken getgrnam() implementations
-19) Merge real time signal fixes for kernel oplock code from HEAD
-20) Fix CIDR hosts allow/deny notation
-21) Fixup tcon&X server responses and error codes
-22) Set domain for users in passdb created by "net rpc vampire"
-23) More scalable printing updates

+Please discuss this release on the samba-technical mailing list or by
+joining the #samba-technical IRC channel on irc.freenode.net.
-1) remove the global_myname string and replace with wrapper function
- global_myname()
-2) create vfs/ and pdb/ subdirectories for library installs
-3) Fixup of ordered cleanup of get_dc_list()
-4) Added more autoconf tests for Stratus VOS
-5) Fixed nasty bug where file writes with start offsets in the
- range 0x80000000 -> 0xFFFFFFFF would fail as they were being cast
- from IVAL (uint32) to SMB_OFF_T (off_t or off64_t, both *signed*
- types). The sign extension would cause the offset to be treated
- as negative.
-6) Add support to automatically retrieve the dns host name and domain
- name of an AD server
-7) Add support for PRINTER_INFO_7 and publishing printer attributes
- in active directory
-8) Fix for 64 bit issues with oplocks and allocation size
-9) Remove assert(count ==1) for multi-homed PDCs when resolving
- DOMAIN<0x1b>

- the PDC
-11) Add some docs on CUPS printing
-12) Fix rpcclient querygroup command
-13) The _abs time functions should not be converting from/to GMT
-14) Fix broken incremental tar in smbclient

-19) Add some friendly versions of NT_STATUS codes
-20) Protect nmbd against malformed reply packets
-21) Removal of unpopular winbind client environment variable
-22) Add msdfs proxy functionality; a CIFS share can directly be a
- stand-in for another share, and when clients connect to the first
- share, they will be redirected to the proxied share
-23) Make Samba compile cleanly with -Wwrite-strings
-24) Add new timegm() that actually works on solaris
-25) Add support for running smbd, nmbd, & winbindd under the daemontools

-45) Add NTLMv2 client code (that works) and some SMB signing fixes
-46) Add caching of PRINTER_INFO_2 structures to open printer handles
-47) Add 1/3 second delay in OpenPrinter() reply to trigger a LAN/WAN
- optimization in Windows 2000 clients
-48) Add "WinXP" to the possible values of the %a variable
-49) Fix to allow blocking lock notification to be done rapidly (no wait for
- smb -> smb lock release). Adds new PENDING_LOCK type to lockdb (does
- not interfere with existing locks)
-50) Limit the unix domain sockets used by winbindd (also solves FD_SETSIZE
- problem in winbindd to boot !). Adds a "last_access" field to winbindd
