This is the -version that all production Samba servers should be running -for all current bug-fixes. - -New/Changed parameters in 2.0.4 -------------------------------- - -There are 5 new parameters and one modified parameter in -the smb.conf file. - -allow trusted domains -restrict anonymous -mangle locks -oplock break wait time -oplock contention limit - -The new parameters are : - -allow trusted domains ---------------------- - -This option is used in "security=domain" settings and allows -the Samba admin to restrict access to users within the domain -the the Samba server is in. - -restrict anonymous ------------------- - -This parameter allows the Samba admin to cause Samba to -refuse access to anonymous users. Use of this parameter -is only recommened for homogenous NT client environments. - -mangle locks ------------- - -This parameter was added to get around a bug in Windows NT -when dealing with Samba running on 32-bit systems (such -as Linux x86). This bug causes NT to send 64 bit locking -requests to 32-bit systems even though Samba correctly -tells the NT client not to do so. This option causes Samba -to map the lock requests from 64 bits to 32 bits on these -systems. - -oplock break wait time ----------------------- - -This tuning parameter, added to help with clients that don't -respond to oplock break requests, causes Samba to deley for -this number of milliseconds before sending an oplock break -request to a client that caused the break to be sent. The -default is 10ms. This is an advanced tuning parameter and -should not be changed lightly. - -oplock contention limit ------------------------ - -This tuning parameter causes Samba not to grant oplocks -when an smbd daemon notices that there have been this -many concurrent requests for an oplock on a file. This -prevents the "baton passing" oplock problem where many -clients accessing one file pass the oplock between themselves -like a baton. The default is 2. This is an advanced tuning -parameter and should not be changed lightly. - -The modified parameter is : - -nt acl support --------------- - -This is a global parameter that defaulted to False in -the previous release (2.0.3) and now defaults to True -as the RPC code has been added to Samba to allow it to -map UNIX permissions to NT ACLs. - -All of these new parameters and changes are documented in the -smb.conf man pages and html pages. - -Updated and New documentation ------------------------------ - -A new document describing the manipulation of UNIX permissions -via the Windows NT security dialogs and their interaction with -Samba 2.0.4 is provided as : - -docs/textdocs/NT_Security.txt -docs/htmldocs/NT_Security.html - -Changes in 2.0.4b ------------------ - -A bug with MS-Word 97 saving files with zero UNIX permissions -was fixed. Even though a workaround is available (set force -create mode = 644 on the share) Word is such an important -application that a point fix was neccessary. - -Changes in 2.0.4a ------------------ - -The text and html versions of NT_Security were missing from -the shipping tarball. Also a compile bug for platforms that -don't have usleep was fixed. - -Bugfixes added since 2.0.3 --------------------------- - -1). Fix for 8 character password problem when using HPUX and -plaintext passwords. -2). --with-pam option added to ./configure. -3). Client fixes for memory leak and display of 64 bit values. -4). Fixes for -E and -s option with smbclient. -5). smbclient now allows -L //server or -L \\server -6). smbtar fix for display of 64 bit values. -7). Endian independence added to DCE/RPC code. -8). DCE/RPC marshalling/unmarshalling code re-written to provide -overflow reporting and sign and seal support. -9). Bind NAK reply packet added to DCE/RPC code, used to correctly -refuse bind requests (prevents NT system event log messages). -10). Mapping of UNIX permissions into NT ACL's for get and set -added. -11). DCE/RPC enumeration of numbers of shares made dynamic. -Samba now has no limit on the number of exported shares seen. -12). Fix to speed up random number seed generation on /dev/urandom -being unavailable. -13). Several memory fixes added by running Purify on the code. -14). Read from client error messages improved. -15). Fixed endianness used in UNICODE strings. -16). Cope with ERRORmoredata in an RPC pipe client call. -17). Check for malformed responses in nmbd register name. -18). NT Encrypted password changing from the NT password dialog box -now fully implmented. -19). Mangle 64-bit lock ranges into 32-bits (NT bug!) on a 32-bit -Samba platform. -20). Allow file to be pseudo-openend in order to read security only. -21). Improve filename mangling to reduce chance of collisions. -22). Added code to prevent granting of oplocks when a file is under -contention. -23). Added tunable wait time before sending an oplock break request -to a client if the client caused the break request. Helps with clients -not responding to oplock breaks. -24). Always respond negatively to queued local oplock break messages -before shutdown. This can prevent "freezes" on an oplock error. -25). Allow admin to restrict logons to correct domain when in domain -level security. -26). Added "restrict anonymous" patch from Andy (thwartedefforts@wonky.org) -to prevent parameter substitution problems with anonymous connections. -27). Fix SMBseek where seeking to a negative number sets the offset -to zero. -28). Fixed problem with mode getting corrupted in trans2 request -(setting to zero means please ignore it). -29). Correctly become the authenticated user on an authenticated -DCE/RPC pipe request. -30). Correctly reset debug level in nmbd if someone set it on the -command line. -31). Added more checking into testparm -32). NetBench simulator added to smbtorture by Andrew. -33). Fixed NIS+ option compile (was broken in 2.0.3). -34). Recursive smbclient directory listing fix. Patch from E. Jay Berkenbilt -(ejb@ql.org) - -Bugfixes added since 2.0.2 --------------------------- - -1). --with-ssl configure now include ssl include directory. Fix -from Richard Sharpe. -2). Patch for configure for glibc2.1 support (large files etc.). -3). Several bugfixes for smbclient tar mode from Bob Boehmer -(boehmer@worldnet.att.net) to fix smbclient aborting problems -when restoring tar files. -4). Some automount fixes for smbmount. -5). Attempt to fix the AIX 4.1.x/3.x problems where smbd runs as -root. As no-one has given us root access to such a server this -cannot be tested fully, but should work. -6). Crash bug fix in debug code where *real* uid rather than -*effective* uid was being checked before attempting to rotate -log files. This fix should help a *lot* of people who were -reporting smbd aborting in the middle of a copy operation. -7). SIGALRM bugfix to ensure infinate file locks time out. -8). New code to implement NT ACL reporting for cacls.exe program. -9). UDP loopback socket rebind fix for Solaris. -10). Ensure all UNICODE strings are correctly in little-endian -format. -11). smbpasswd file locking fix. -12). Fixes for strncpy problems with glibc2.1. -13). Ensure smbd correctly reports major and minor version number -and server type when queried via NT rpc calls. -14). Bugfix for short mangled names not being pulled off the -mangled stack correctly. -15). Fix for mapping of rwx bits being incorrectly overwritten -when doing ATTRIB.EXE -16). Fix for returning multiple PDU packets in NT rpc code. Should -allow multiple shares to be returned correctly). -17). Improved mapping of NT open access requests into UNIX open -modes. -18). Fix for copying files from an NTFS volume that contain -multiple data forks. Added 'magic' error code NT needs. -19).

Now will -always occur even if smbd is under load. -21). Fixed signed/unsigned problem in quotas code. -22). Fixed bug where setting the password of a completely fresh -user would end up setting the account disabled flag. -23). Improved user logon messages to help admins having -trouble with user authentication. - -Bugfixes added since 2.0.1 --------------------------- - -Note that due to a critical signal handling bug in 2.0.1, -this release has been removed and replaced immediately with -2.0.2. The Samba Team would like to apologise for any problem -this may have caused. - -1). Fixed smbd looping on SIGCLD problem. This was - caused by a missing break statement in a critical - piece of code. - -Bugfixes added since 2.0.0 --------------------------- - -1). Autoconf changes for gcc2.7.x and Solaris 2.5/2.6 -2). Autoconf changes to help HPUX configure correctly. -3). Autoconf changes to allow lock directory to be set. -4).

These have mainly been in the areas of performance and -SMB protocol correctness. In addition, a Web based GUI interface -for configuring Samba has been added. - -In addition, Samba has been re-written to help portability to -other POSIX-based systems, based on the GNU autoconf tool. - -There are many major changes in Samba for version 2.0. Here are -some of them: - -===================================================================== - -1). Speed ---------- - -Samba has been benchmarked on high-end UNIX hardware as out-performing -all other SMB/CIFS servers using the Ziff-Davis NetBench benchmark. -Many changes to the code to optimise high-end performance have been made. - -2). Correctness ---------------- - -Samba now supports the Windows NT specific SMB requests. This -means that on platforms that are capable Samba now presents a -64 bit view of the filesystem to Windows NT clients and is -capable of handling very large files. - -3). Portability ---------------- - -Samba is now self-configuring using GNU autoconf, removing -the need for people installing Samba to have to hand configure -Makefiles, as was needed in previous versions. - -You now configure Samba by running "./configure" then "make". See -docs/textdocs/UNIX_INSTALL.txt for details. - -4). Web based GUI configuration -------------------------------- - -Samba now comes with SWAT, a web based GUI config system. See -the swat man page for details on how to set it up. - -5). Cross protocol data integrity ---------------------------------- - -An open function interface has been defined to allow -"opportunistic locks" (oplocks for short) granted by Samba -to be seen by other UNIX processes. This allows complete -cross protocol (NFS and SMB) data integrety using Samba -with platforms that support this feature. - -6). Domain client capability ----------------------------- - -Samba is now capable of using a Windows NT PDC for user -authentication in exactly the same way that a Windows NT -workstation does, i.e. it can be a member of a Domain. See -docs/textdocs/DOMAIN_MEMBER.txt for details. - -7). Documentation Updates -------------------------- - -All the reference parts of the Samba documentation (the -manual pages) have been updated and converted to a document -format that allows automatic generation of HTML, SGML, and -text formats. These documents now ship as standard in HTML -and manpage format. - -===================================================================== - -NOTE - Some important option defaults changed ---------------------------------------------- - -Several parameters have changed their default values. The most -important of these is that the default security mode is now user -level security rather than share level security. - -This (incompatible) change was made to ease new Samba installs -as user level security is easier to use for Windows 95/98 and -Windows NT clients. - -********IMPORTANT NOTE**************** - -If you have no "security=" line in the [global] section of -your current smb.conf and you update to Samba 2.0 you will -need to add the line : - -security=share - -to get exactly the same behaviour with Samba 2.0 as you -did with previous versions of Samba. - -********END IMPORTANT NOTE************* - -In addition, Samba now defaults to case sensitivity options that -match a Windows NT server precisely, that is, case insensitive -but case preserving. - -The default format of the smbpasswd file has also been -changed for this release, although the new tools will read -and write the old format, for backwards compatibility. - -===================================================================== - -NOTE - Primary Domain Controller Functionality ----------------------------------------------- - -This version of Samba contains code that correctly implements -the undocumented Primary Domain Controller authentication -protocols. However, there is much more to being a Primary -Domain Controller than serving Windows NT logon requests. - -A useful version of a Primary Domain Controller contains -many remote procedure calls to do things like enumerate users, -groups, and security information, only some of which Samba currently -implements. In addition, there are outstanding (known) bugs with -using Samba as a PDC in this release that the Samba Team are actively -working on. For this reason we have chosen not to advertise and -actively support Primary Domain Controller functionality with this -release. - -This work is being done in the CVS (developer) versions of Samba, -development of which continues at a fast pace. If you are -interested in participating in or helping with this development -please join the Samba-NTDOM mailing list. Details on joining -are available at : - -http://samba.org/listproc/ - -Details on obtaining CVS (developer) versions of Samba -are available at: - -http://samba.org/cvs.html - -===================================================================== - -If you have problems, or think you have found a bug please email -a report to : - - samba-bugs@samba.org - -As always, all bugs are our responsibility. - -Regards, - - The Samba Team. + WHATS NEW IN Samba 3.0 alpha0 + ============================= + +This is a pre-release of Samba 3.0 alpha0. 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 are +planning on ceasing development on the 2.2.x release of Samba very +shortly and after that we will be concentrating on Samba 3.0. To +reduce the time before the final Samba 3.0 release we need as many +poeple 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 anywhere near feature complete yet. There +is a lot 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 is also missing major pieces of documentation, and there +are many parts of the docs that have not been updated to reflect the +new options and features in 3.0. + +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. Please read ADS-HOWTO.txt in the release for a very + rough guide on how to set this up. + +- Unicode support. Samba will now negotiate unicode on the wire and + interally there is now a much better infrastructure for multi-byte + and unicode character sets. You may need the "dos charset", "unix + charset" and "display charset" options. The unicode support is not + yet documented. + +- 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. Not documented + yet. + +- new filename mangling system. The filename mangling system has been + completely rewritten. An internal database now stores mangling maps + persistantly. 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. The support for printing from win2000 + clients has improved greatly. + +Plus lots of other changes! + +Note that many new features are not documented. Don't let this stop +you from using Samba 3.0. It is particularly important that the basic +file/print serving abilities of Samba 3.0 are widely tested to ensure +that we have not broken any of the basic functionality. As we do more +alpha releases we will start to document the new features. + + +Reporting bugs & Development Discussion +--------------------------------------- + +Please discuss this release on the samba-technical mailing list or by +joining the #samba-technical IRC channel on irc.openprojects.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. |
