The main emphasis in -this branch is support for the Active Directory logon protocols used -by Windows 2000 and above. - -Samba 4 is currently not yet in a state where it is usable in -production environments. Note the WARNINGS below, and the STATUS file, -which aims to document what should and should not work. - -Samba4 alpha4 follows on from the alpha release series we have been -publishing since September last year. - -WARNINGS -======== - -Samba4 alpha4 is not a final Samba release. That is more a reference -to Samba4's lack of the features we expect you will need than a -statement of code quality, but clearly it hasn't seen a broad -deployment yet. If you were to upgrade Samba3 (or indeed Windows) to -Samba4, you would find many things work, but that other key features -you may have relied on simply are not there yet. - -For example, while Samba 3.0 is an excellent member of a Active -Directory domain, Samba4 is happier as a domain controller: (This is -where we have done most of the research and development). - -While Samba4 is subjected to an awesome battery of tests on an -automated basis, and we have found Samba4 to be very stable in it's -behaviour, we have to recommend against upgrading production servers -from Samba 3 to Samba 4 at this stage. If you are upgrading an -experimental server, or looking to develop and test Samba, you should -backup all configuration and data. - -NEW FEATURES -============ - -Samba4 supports the server-side of the Active Directory logon environment -used by Windows 2000 and later, so we can do full domain join -and domain logon operations with these clients. - -Our Domain Controller (DC) implementation includes our own built-in -LDAP server and Kerberos Key Distribution Center (KDC) as well as the -Samba3-like logon services provided over CIFS. We correctly generate -the infamous Kerberos PAC, and include it with the Kerberos tickets we -issue. - -The new VFS features in Samba 4 adapts the filesystem on the server to -match the Windows client semantics, allowing Samba 4 to better match -windows behaviour and application expectations. This includes file -annotation information (in streams) and NT ACLs in particular. The -VFS is backed with an extensive automated test suite. - -A new scripting interface has been added to Samba 4, allowing -Python programs to interface to Samba's internals. - -The Samba 4 architecture is based around an LDAP-like database that -can use a range of modular backends. One of the backends supports -standards compliant LDAP servers (including OpenLDAP), and we are -working on modules to map between AD-like behaviours and this backend. -We are aiming for Samba 4 to be powerful frontend to large -directories. - -CHANGES SINCE Alpha3 +Release Announcements ===================== -In the time since Samba4 Alpha2 was released in December 2007, Samba has -continued to evolve, but you may particularly notice these areas: +This is the first preview release of Samba 4.4. This is *not* +intended for production environments and is designed for testing +purposes only. Please report any defects via the Samba bug reporting +system at https://bugzilla.samba.org/. - Python Bindings: Bindings for Python are now used for all internal - scripting, and the system python installation is used to run all - Samba python scripts (in place of smbpython found in the previous - alpha). +Samba 4.4 will be the next version of the Samba suite. - As such Python is no longer optional, and configure will generate an - error if it cannot locate an appropriate Python installation. - SWAT Remains Disabled: Due to a lack of developer time and without a - long-term web developer to maintain it, the SWAT web UI remains been - disabled (and would need to be rewritten in python in any case). +UPGRADING +========= - GNU Make: To try and simplfy our build system, we rely on GNU Make - to avoid autogenerating a massive single makefile. +Nothing special. + +NEW FEATURES +============ - Registry: Samba4's registry library has continued to improve. +Flush requests from SMB2/3 clients are handled asynchronously and do +not block the processing of other requests. Note that 'strict sync' +has to be set to 'yes' for Samba to honor flush requests from SMB +clients. - ID mapping: Samba4 uses the internal ID mapping in winbind for all - but a few core users. Samba users should not appear in /etc/passwd, - as Samba will generate new user and group IDs regradless. +WINS nsswitch module +==================== - NTP: Samba4 can act as a signing server for the ntp.org NTP deamon, - allowing NTPd to reply using Microsoft's non-standard signing - scheme. A patch to make NTPd talk to Samba for this purpose has - been submitted to the ntp.org project. +The WINS nsswitch module has been rewritten to address memory issues and to +simplify the code. The module now uses libwbclient to do WINS queries. This +means that winbind needs to be running in order to resolve WINS names using +the nss_wins module. This does not affect smbd. - CLDAP: Users should experience less arbitary delays and more success with - group policy, domain joins and logons due to an improved - implementation of CLDAP and the 'netlogon' mailslot datagrams. +###################################################################### +Changes +####### - SMB2: The Samba4 SMB2 server and testsuite have been greatly - improved, but the SMB2 server remains off by default. +smb.conf changes +---------------- - Secure DNS update: Configuration for GSS-TSIG updates of DNS records - is now generated by the provision script. + Parameter Name Description Default + -------------- ----------- ------- + aio max threads New 100 -These are just some of the highlights of the work done in the past few -months. More details can be found in our GIT history. +CTDB changes +------------ +* The CTDB tunable parameter EventScriptTimeoutCount has been renamed + to MonitorTimeoutCount -CHANGES -======= + It has only ever been used to limit timed-out monitor events. -Those familiar with Samba 3 can find a list of user-visible changes -since that release series in the NEWS file. + Configurations containing CTDB_SET_EventScriptTimeoutCount= will + cause CTDB to fail at startup. Useful messages will be logged. KNOWN ISSUES ============ -- Domain member support is in it's infancy, and is not comparable to - the support found in Samba3. - -- There is no printing support in the current release. - -- There is no netbios browsing support in the current release - -- The Samba4 port of the CTDB clustering support is not yet complete - -- Clock Synchronisation is critical. Many 'wrong password' errors are - actually due to Kerberos objecting to a clock skew between client - and server. (The NTP work is partly to assist with this problem). - -- Samba4 alpha4 is currently only portable to recent Linux - distributions. Work to return support for other Unix varients is - expected during the next alpha cycle - -- Samba4 alpha4 is incompatible with GnuTLS 2.0, found in Fedora 9 and - recent Ubuntu releases. Please remove the - gnutls-devel/libgnutls-dev package before compiling (otherwise 'make - test' and LDAPS operations will hang). +Currently none. -RUNNING Samba4 -============== +####################################### +Reporting bugs & Development Discussion +####################################### -A short guide to setting up Samba 4 can be found in the howto.txt file -in root of the tarball. +Please discuss this release on the samba-technical mailing list or by +joining the #samba-technical IRC channel on irc.freenode.net. -DEVELOPMENT and FEEDBACK -======================== -Bugs can be filed at https://bugzilla.samba.org/ but please be aware -that many features are simply not expected to work at this stage. +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. All bug reports should +be filed under the Samba 4.3 product in the project's Bugzilla +database (https://bugzilla.samba.org/). -The Samba Wiki at http://wiki.samba.org should detail some of these -development plans. -Development and general discussion about Samba 4 happens mainly on -the #samba-technical IRC channel (on irc.freenode.net) and -the samba-technical mailing list (see http://lists.samba.org/ for -details). +====================================================================== +== Our Code, Our Bugs, Our Responsibility. +== The Samba Team +======================================================================
