WHATS NEW IN Samba 3.0 alpha23 30th March 2003 ============================== This is a pre-release of Samba 3.0. This is NOT a stable release. Use at your own risk. The purpose of this alpha release is to get wider testing of the major new pieces of code in the current Samba 3.0 development tree. We have officially ceased development on the 2.2.x release of Samba and are concentrating on Samba 3.0. To reduce the time before the final Samba 3.0 release we need as many people as possible to start testing these alpha releases, and hopefully giving us some high quality feedback on what needs fixing. Note that Samba 3.0 is not feature complete yet. There is a more coding we have planned, but unless we get what we have done already 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. - Samba now negotiates NT-style status32 codes on the wire. This improves error handling a lot. - better w2k printing support including publishing printer attributes in active directory - new loadable RPC modules - new dual-daemon winbindd support for better performance - support for migrating from a Windows NT 4.0 domain - support for establishing trust relationships with Windows NT 4.0 domain controllers Plus lots of other changes! 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. Changes in alpha23: ------------------- LDAP Group Mapping ------------------ 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 root# pdbedit -i tdbsam -e ldapsam -g to transfer your group mapping database to LDAP. 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. Parameters ---------- Modified Parameters (see smb.conf(5) for details): * passdb backend Added Parameters * ldap del only sam attr * ldap delete dn 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 =============================== Changes in older alpha releases follow: --------------------------------------------------------------------- Changes in alpha22: ------------------- Added Parameters * client NTLMv2 auth * client lanman auth * client signing * client use spnego * max reported print jobs * msdfs proxy 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> 10) Ensure that change_trust_account_password() always talks to 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 15) Adding supporting code for better testing using Valgrind 16) Fix for old DOS client when veto files is set to /.*/ 17) Add win32 utility to query driver capabilities to publish (examples/printing/prtpub.c) 18) Fix memory leak when constructing an driver_level_6 structure and no dependent files 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 package 26) Move user password changes into the NTSTATUS era, and add support for the 'min password age' and 'min passwd len' concepts 27) Add new gencache based namecache code 28) Add profiles utility support to Samba 3.0.x 29) Fix open problem with changing attributes on an existing file 30) Efficiency fixes for internal messaging system 31) Make sure to update print queue cache during timeout_processing() to send notify events 32) Make -i flag work like it did in 2.2 33) Merge some rpcclient and net functionality from HEAD 34) Add support for compiling with Heimdal kerberos libraries 35) Connect to the actual netbios name in smb.conf and not LOCALHOST 36) Add support for CUPS-PRINTER_CLASS 37) Add ntlm_auth tool and update NTLMSSP support 38) require Autoconf 2.53 and remove configure from CVS 39) Check for too many processes *before* the fork 40) Fix delete on close semantics to match W2K. 41) merge desired_access for open_printer_ex from HEAD, allowing cupsaddsmb to work again! 42) Add support for dynamic RPC modules 43) wrap all cm_get_XX calls and their subsequent requests in a retry loop in case we've temporarily lost connection to the DC. Makes winbindd more reliable 44) Optimize user_ok() and user_in_group() when verifying group membership 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 connections, and will close the oldest idle connection once the number of open connections goes over WINBINDD_MAX_SIMULTANEOUS_CLIENTS (defined in local.h as 200 currently) 51) Limit the number of print jobs returned in EnumJobs()
