- WHATS NEW IN 1.9.18alpha7 Oct 29th 1997
- =======================================
+ WHATS NEW IN Samba 3.0 alpha23
+ 30th March 2003
+ ==============================
-This is NOT a production release of Samba code.
-For production servers please run Samba 1.9.17p4
-or later releases in the 1.9.17 series.
+This is a pre-release of Samba 3.0. This is NOT a stable release.
+Use at your own risk.
-This release contains some experimental features and
-changes and is being made available so people can
-test and provide feedback and patches for ongoing
-Samba development.
+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.
-Please note that only the Domain controller code
-is truly experimental. The other changes have
-been extensively tested and are of the same
-quality as normal Samba alpha releases. The
-Domain controller code is disabled in the Makefile
-by default and is being made available to Samba
-programmers in the interests of advancing a
-public implementation of this important protocol.
+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.
-This release contains three major changes to the
-1.9.17 series and much re-written code.
+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.
-The main changes are :
+- 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.
-1). Oplock support now operational.
------------------------------------
+- 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.
-Samba now supports 'exclusive' and 'batch' oplocks.
-These are an advanced networked file system feature
-that allows clients to obtain a exclusive use of a
-file. This allows a client to cache any changes it
-makes locally, and greatly improves performance.
+- 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.
-Windows NT has this feature and prior to this
-release this was one of the reasons Windows NT
-could be faster in some situations.
+- 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.
-The oplock code in Samba has been extensively
-tested and is believed to be completely stable.
+- Samba now negotiates NT-style status32 codes on the wire. This
+ improves error handling a lot.
-Please report any problems to the samba-bugs alias.
+- better w2k printing support including publishing printer
+ attributes in active directory
+- new loadable RPC modules
-2). Experimental Primary Domain controller code.
-------------------------------------------------
+- new dual-daemon winbindd support for better performance
-Samba now contains a *VERY* experimental client and
-server implementation of part of the Windows NT
-4.x Domain Controller specification, as
-published by Paul Ashton (now a Samba Team
-member).
+- support for migrating from a Windows NT 4.0 domain
-This code is not enabled in the Makefile by default,
-and to work on this code you must read the file :
+- support for establishing trust relationships with Windows NT 4.0
+ domain controllers
- docs/NTDOMAIN.txt
+Plus lots of other changes!
-Please note that as this code is not complete,
-it is being made available as part of this release
-to allow interested parties to contribute and help
-the Samba Team in documenting and implementing
-this important feature.
-Please do not expect to be able to replace your
-NT Domain Controllers with Samba until this code
-is finished, tested and an announcement is made.
+Reporting bugs & Development Discussion
+---------------------------------------
-At present the Domain Controller code is for
-programmers and people interested in Microsoft
-protocols only.
+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.
-3). New Internationalization support.
--------------------------------------
-With this release Samba no longer needs to be
-separately compiled for Japanese (Kanji) support,
-the same binary will serve both Kanji and non-Kanji
-clients.
+Changes in alpha23:
+-------------------
-A new method of dynamically loading client code pages
-has been added to allow the case insensitivity to
-be done dependent on the code page of the client.
+ LDAP Group Mapping
+ ------------------
-Note that Samba still will only handle one client
-code page at a time. This will be fixed when
-Samba is fully UNICODE enabled.
+ 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()
-Please see the new man page for make_smbcodepage
-for details on adding additional client code page
-support.

-
-Changed code.
--------------
-
-Samba no longer needs the libdes library to support
-encrypted passwords. Samba now contains a restricted
-version of DES that can only be used for authentication
-purposes (to comply with the USA export encryption
-regulations and to allow USA Mirror sites to carry
-Samba source code). The 'encrypt passwords' parameter
-may now be used without recompiling.
-
-Much of the internals of Samba has been re-structured
-to support the oplock and Domain controller changes.
-
-The WINS client and WINS server capabilities in nmbd
-are also being restructured, to make it easier to
-understand and maintain.
-
-Samba supports the NT 3.51 and 4.0 Domain Authentication
-Protocol to a degree sufficient to download Profiles to an
-NT 3.51 or 4.0 Workstation ("Welcome to the SAMBA Domain").
-
-There is also code in smbclient to generate the same
-requests as an NT Workstation would when doing an NT
-Domain Logon. This has only been tested against a Samba
-"Experimental" PDC so far.
-
-Some of the new parameters for NT Domain Logons and
-Profile support are now also used by the Win95 Domain
-Logons and Profile support.
-
-The Automount code has been slightly reshuffled, such
-that the home directory (and profile location) can be
-specified by \\%N\homes and \\%N\homes\profiles
-respectively, which are the defaults for these values.
-If -DAUTOMOUNT is enabled, then %N is the server
-component of the user's NIS auto.home entry. Obviously,
-you will need to be running Samba on the user's home
-server as well as the one they just logged in on.
-
-
-New parameters in smb.conf.
----------------------------
-
-New Global parameters.
-----------------------
-
-Documented in the smb.con man pages :
-
-"bind interfaces only"
-"username level"
-
-"domain sid"
-"domain groups"
-
-"logon drive"
-"logon home"
-
-
-Not yet documented in the smb.conf man page, please
-read docs/NTDOMAIN.txt or examine the source code for
-information on the next parameters :
-
-"domain other sids"
-"domain admin users"
-"domain guest users"
-
-
-New Share level parameters.
----------------------------
-
-Documented in the smb.con man pages :

-
-Reporting bugs.
----------------
-
-If you have problems, or think you have found a
-bug please email a report to :
-
-samba-bugs@samba.anu.edu.au
-
-Please state the version number of Samba that
-you are running, and *full details* of the steps
-we need to reproduce the problem.
-
-As always, all bugs are our responsibility.
