WHATS NEW IN Samba 3.0.1pre3 November 14, 2003 ============================== This is a preview release of the Samba 3.0.1 code base and is provided for testing only. This release is *not* intended for production servers. Use at your own risk. There have been several bug fixes since the 3.0.0 release that we feel are important to make available to the Samba community for wider testings. See the "Changes" section for details on exact updates. ###################################################################### Changes ####### Changes since 3.0.1pre2 ----------------------- Please refer to the CVS log for the SAMBA_3_0 branch for complete details: 1) Skip over the winbind separator when looking up a user. This fixes the bug that prevented local users from matching an AD user when not running winbindd (bug 698). 2) Fix a problem with configure on *BSD systems. Make sure we add -liconv etc to LDFLAGS. 3) Fix core dump bug when "security = server" and the authentication server goes away. 4) Correct crash bug due to an empty munged dial string. 5) Show files locked by a specific user (smbstatus -u 'user') (bug 590). 6) Fix bug preventing print jobs from display in the queue monitor used by Windows NT and later clients (bug 660). 7) Fix several reported problems with point-n-print from Windows 2000/XP clients due to a bug in the EnumPrinterDataEx() reply (bug 338, 527 & 643). 8) Fix a handful of potential memory leaks in the LDAP code used by ldapsam[_compat] and the LDAP idmap backend. Changes since 3.0.1pre1 ----------------------- 1) Match Samba 2.2 behavior; make ACB_NORMAL the default ACB value. 2) Updated Japanese welcome file in SWAT. 3) Fix to nt-time <-> unix-time functions reversible. 4) Ensure that winbindd uses the the escaped DN when querying an AD ldap server. 5) Fix portability issues when compiling (bug 505, 550) 6) Compile fix for tdbbackup when Samba needs to override non-C99 compliant implementations of snprintf(). 7) Use @PICSUFFIX@ instead of .po in Makefile.in (bug 574). 8) Make sure we break out of samsync loop on error. 9) Ensure error code path doesn't free unmalloc()'d memory (bug 628). 10) Add configure test for krb5_keytab_entry keyblock vs key member (bug 636). 11) Fixed spinlocks. 12) Modified testparm so that all output so all debug output goes to stderr, and all file processing goes to stdout. 13) Fix error return code for BUFFER_TOO_SMALL in smbcacls and smbcquotas. 14) Fix "NULL dest in safe_strcpy()" log message by ensuring that we have a devmode before copying a string to the devicename. 15) Support mapping REALM.COM\user to a local user account (without running winbindd) for compatibility with 2.2.x release. 16) Ensure we don't use mmap() on blacklisted systems. 17) fixed a number of bugs and memory leaks in the AIX winbindd shim 18) Call initgroups() in SWAT before becomming the user so that secondary group permissions can be used when writing to smb.conf. 19) Fix signing problems when reverse connecting back to a client for printer notify 20) Fix signing problems caused by a miss-sequence bug. 21) Missing map in errormap for ERROR_MORE_DATA -> ERRDOS, ERRmoredata. Fixes NEXUS tools running on Win9x clients (bug 64). 22) Don't leave the domain field uninitialized in cli_lsa.c if some SID could not be mapped. 23) Fix segfault in mount.cifs helper when there is no options specified during mount. 24) Change the \n after the password prompt to go to tty instead of stdout (bug 668). 25) Stop net -P from prompting for machine account password (bug 451). 26) Change in behavior to Not only change the effective uid but also the real uid when becoming unprivileged. 27) Cope with Exchange 5.5 cleartext pop password auth. 28) New files for support of initshutdown pipe. Win2k doesn't respond properly to all requests on the winreg pipe, so we need to handle this new pipe (bug 534). 29) Added more va_copy() checks in configure.in. 30) Include fixes for libsmbclient build problems. 31) Missing UNIX -> DOS codepage conversion in lanman.c. 32) Allow DFMS-S filenames can now have arbitrary case (bug 667). 33) Parameterize the listen backlog in smbd and make it larger by default. A backlog of 5 is way too small these days. 34) Check for an invalid fid before dereferencing the fsp pointer (bug 696). 35) Remove invalid memory frees and return codes in pdb_ldap.c. 36) Prompt for password when invoking --set-auth-user and no password is given. 37) Bind the nmbd sending socket to the 'socket address'. 38) Re-order link command for smbd, rpcclient and smbpasswd to ensure $LDFLAGS occurs before any library specification (bug 661). 39) Fix large number of printf() calls for 64-bit size_t. 40) Fix AC_CHECK_MEMBER so that SLES8 does correctly finds the keyblock in the krb5 structs. 41) Remove #include <compat.h> in hopes to avoid problems with apache header files. 42) COrrect winbindd build problems on HP-UX 11 43) Lowercase netgroups lookups (bug 703). 44) Use the actual size of the buffer in strftime instead of a made up value which just happens to be less than sizeof(fstring). (bug 713). 45) Add ldaplibs to pdbedit link line (bug 651). 46) Fix crash bug in smbclient completion (bug 659). 47) Fix packet length for browse list reply (bug 771). 48) Fix coredump in cli_get_backup_list(). 49) Make sure that we expand %N (bug 612). 50) Allow rpcclient adddriver command to specify printer driver version (bug 514). 51) Compile tdbdump by default. 52) Apply patches to fix iconv detection for FreeBSD. 53) Do not allow the 'guest account' to be added to a passdb backend using smbpasswd or pdbedit (bug 624). 54) Save LDFLAGS during iconv detection (bug 57). 55) Run krb5 logins through the username map if the winbindd lookup fails (bug 698). 56) Add const for lp_set_name_resolve_order() to avoid compiler warnings (bug 471). 57) Add support for the %i macro in smb.conf to stand in for the for the local IP address to which a client connected. 58) Allow winbindd to match local accounts to domain SID when 'winbind trusted domains only = yes' (bug 680). 59) Remove code in idmap_ldap that searches the user suffix and group suffix. It's not needed and provides inconsistent functionality from the tdb backend. 60) Patch to handle munged dial string for Windows 200 TSE. 61) Correct the "smbldap_open: cannot access when not root error" messages when looking up group information (bug 281). Changes since 3.0.0 ------------------- Modified parameters * mangled map (deprecated) Removed Parameters * mangled stack (unused) 1) Change the interface for init_unistr2 to not take a length but a flags field. We were assuming that 2*strlen(mb_string) == length of ucs2-le string. (bug 480). 2) Allow d_printf() to handle strings with escaped quotation marks since the msg file includes the escape character (bug 489). 3) Fix bad html table row termination in SWAT wizard code (bug 413). 4) Fix to parse the level-2 strings. 5) Fix for "valid users = %S" in [homes]. Fix read/write list as well. 6) Change AC_CHECK_LIB_EXT to prepend libraries instead of append. This is the same way AC_CHECK_LIB works (bug 508). 7) Testparm output fixes for clarity. 8) Fix broken wins hook functionality -- i18n bug (bug 528). 9) Take care of condition where DOS and NT error codes must differ. 10) Default to using only built-in charsets when a working iconv implementation cannot be located. 11) Wrap internals of sys_setgroups() so the sys_XX() call can be done unconditionally (bug 550). 12) Remove duplicate smbspool link on SWAT's front page (bug 541). 13) Save and restore CFLAGS before/after AC_PROG_CC. Ensures that --enable-debug=[yes|no] works correctly. 14) Allow ^C to interrupt smbpasswd if using our getpass (e.g. smbpasswd command). 15) Support signing only on RPC's (bug 167). 16) Correct bug that prevented Excel 2000 clients from opening files marked as read-only. 17) Portability fix bugs 546 - 549). 18) Explicitly initialize the value of AR for vendor makes that don't do this (e.g. HPUX 11). (bug 552). 19) More i18n fixes for SWAT (bug 413). 20) Change the cwd before the postexec script to ensure that a umount will succeed. 21) Correct double free that caused winbindd to crash when a DC is rebooted (bug 437). 22) Fix incorrect mode sum (bug 562). 23) Canonicalize SMB_INFO_ALLOCATION in the same was as SMB_FS_FULL_SIZE_INFORMATION (bug 564). 24) Add script to generate *msg files. 25) Add Dutch SWAT translation file. 26) Make sure to call get_user_groups() with the full winbindd name for a user if he/she has one (bug 406). 27) Fix up error code returns from Samba4 tester. Ensure invalid paths are validated the same way. 28) Allow Samba3 to pass the Samba4 RAW-READ tests. 29) Refuse to configure if --with-expsam=$BACKEND was used but no libraries were found for $BACKEND. 30) Move sysquotas autoconf tests to a separate file. 31) Match W2K w.r.t. writelock and writeclose. Samba4 torture tester 32) Make sure that the files that contain the static_init_$subsystem; macro get recompiled after configure by removing the object files. 33) Ensure canceling a blocking lock returns the correct error message. 34) Match Samba 2.2, and make ACB_NORMAL the default ACB value. ###################################################################### ======================================= The original 3.0.0 release notes follow ======================================= 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. ###################################################################### 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 * nt smb support * postscript * printer driver * printer driver file * printer driver location * 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 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 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=..." > 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. 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. This server, located at https://bugzilla.samba.org/, has replaced the older jitterbug server previously located at http://bugs.samba.org/.
