-What's new in Samba 4 alpha5
-============================
+ =================================
+ Release Notes for Samba 3.4.0pre2
+ June 02, 2009
+ =================================
-Samba 4 is the ambitious next version of the Samba suite that is being
-developed in parallel to the stable 3.0 series. The main emphasis in
-this branch is support for the Active Directory logon protocols used
-by Windows 2000 and above.
-Samba4 alpha5 follows on from the alpha release series we have been
-publishing since September 2007
+This is the second preview release of Samba 3.4. 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/.
-WARNINGS
-========
-Samba4 alpha5 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.
+Major enhancements in Samba 3.4.0 include:
+------------------------------------------
-For example, while Samba 3.0 is an excellent member of a Active
-Directory domain, Samba4 is happier as a domain controller, and it is
-in this role where it has seen deployment into production.
+General changes:
+o Samba4 and Samba3 sources are included in the tarball
-Samba4 is subjected to an awesome battery of tests on an
-automated basis, 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, because there may be the features on
-which you may rely that are not present, or the mapping of
-your configuration and user database may not be complete.
+Authentication Changes:
+o Changed the way smbd handles untrusted domain names given during user
+ authentication.
-If you are upgrading, or looking to develop, test or deploy Samba4, you should
-backup all configuration and data.
+Printing Changes:
+o Various fixes including printer change notificiation for Samba spoolss
+ print servers.
-NEW FEATURES
-============
+Internal changes:
+o The remaining hand-marshalled DCE/RPC services (ntsvcs, svcctl, eventlog
+ and spoolss) were replaced by autogenerated code based on PIDL.
+o Samba3 and Samba4 do now share a common tevent library.
+o The code has been cleaned up and the major basic interfaces are shared with
+ Samba4 now.
+o An asynchronous API has been added.
-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.
+net Command Changes:
+o Parameter syntax made more consistent.
-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.
+General Changes
+===============
-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.
+On the way towards a standalone Samba AD domain controller, Samba3 and Samba4
+branches can be built as "merged" build. That's why Samba3 and Samba4 sources
+are included in the tarball. The merged build is possible in Samba 3.4.0, but
+disabled by default. To learn more about the merged build,
+please see http://wiki.samba.org/index.php/Franky.
-A new scripting interface has been added to Samba 4, allowing
-Python programs to interface to Samba's internals.
+According to this one, there is no "source" directory included in the tarball at
+all. Samba3 sources are located in "source3", Samba4 sources are located in
+"source4". The libraries have been moved to the toplevel directory.
-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.
+To build plain Samba3, please change to "source3" and start the build as usual.
+To build Samba4 as well, please use the "--enable-merged-build" configure
+option.
-CHANGES SINCE Alpha4
-=====================
-In the time since Samba4 Alpha4 was released in June 2008, Samba has
-continued to evolve, but you may particularly notice these areas:
+Authentication Changes
+======================
- LDAP backend support restored (issues preventing the use of the LDAP
- backend in alpha4 have been addressed)
+Previously, when Samba was a domain member and a client was connecting using an
+untrusted domain name, such as BOGUS\user smbd would remap the untrusted
+domain to the primary domain smbd was a member of and attempt authentication
+using that DOMAIN\user name. This differed from how a Windows member server
+would behave. Now, smbd will replace the BOGUS name with it's SAM name. In
+the case where smbd is acting as a PDC this will be DOMAIN\user. In the case
+where smbd is acting as a domain member server this will be WORKSTATION\user.
+Thus, smbd will never assume that an incoming user name which is not qualified
+with the same primary domain, is part of smbd's primary domain.
- SMB2 Support: The SMB2 server, while still disabled, has improved,
- and now supports SMB2 signing.
+While this behavior matches Windows, it may break some workflows which depended
+on smbd to always pass through bogus names to the DC for verification. A new
+parameter "map untrusted to domain" can be enabled to revert to the legacy
+behavior.
- OpenChange support: Updates have been made since alpha4 to better
- support OpenChange's use of Samba4's libraries.
- Faster ldb loading: A fix to avoid calling 'init_module' (which was
- not defined by Samba modules, but was by the C library) will fix
- some of the slowness in authentication.
+Printing Changes
+================
- 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).
+The spoolss subsystem was replaced by autogenerated code based on PIDL. That fixes
+several printing issues including printer change notificiation on Samba print
+servers and will stabilize the printing functionality generally.
+The support for spoolss printing with Windows Vista has been improved.
- GNU Make: To try and simplfy our build system, we rely on GNU Make
- to avoid autogenerating a massive single makefile.
+Internal Changes
+================
-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.
+The remaining hand-marshalled DCE/RPC services (ntsvcs, svcctl, eventlog and
+spoolss) were replaced by autogenerated code based on PIDL.
+So Günther Deschner finally corrected one of the biggest mistakes in the
+development of Samba: Hand-marshalled RPC stubs.
+Thanks a lot! :-)
-CHANGES
-=======
+Samba3 and Samba4 do now share a common tevent library for fd and timer events.
-Those familiar with Samba 3 can find a list of user-visible changes
-since that release series in the NEWS file.
+The code has been cleaned up and Samba3 and Samba4 do share the major basic
+interfaces now. That is why the libraries were moved to the toplevel directory.
+That is one of the first steps to share code and minimize the gap between
+these two versions.
-KNOWN ISSUES
-============
+An asynchronous API has been added.
-- 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.
+net Command Changes
+===================
-- There is no netbios browsing support in the current release
+The net command now accepts the common command line parameters most other Samba
+command line utilities use, with a couple of remaining differences:
-- The Samba4 port of the CTDB clustering support is not yet complete
+-l still gives long output for net commands supporting the --long flag. This was
+more useful than the common --log-base parameter.
-- 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 in the previous alpha is partly to assist
- with this problem).
+-i still tells net to read data from stdin (like --stdin) instead of toggling
+the common --scope flag.
-- Samba4 alpha5 is currently only portable to recent Linux
- distributions. Work to return support for other Unix varients is
- expected during the next alpha cycle
+-S still tells net the server to connect to (like --server) instead of
+negotiating the common --signing flag. As -S is probably used by most scripts
+doing net rpc commands, this would have been a high-impact change for little
+gain.
-- Samba4 alpha5 is incompatible with GnuTLS 2.0, found in Fedora 9 and
- recent Ubuntu releases. GnuTLS use may be disabled using the
- --disable-gnutls argument to ./configure. (otherwise 'make test' and
- LDAPS operations will hang).
+This change was mainly done to unify the authentification options. Here, one
+flag changed it's meaning and one useful flag was added.
-RUNNING Samba4
-==============
+-N used to be the short version of --ntname. It now matches the Samba default of
+--no-pass. Use this to stop net from prompting for a password if you want
+anonymous authentication.
-A short guide to setting up Samba 4 can be found in the howto.txt file
-in root of the tarball.
+-A --authentication-file now takes an authentication file with the username and
+password you want net to use, avoiding a password prompt as with plain -U user
+or having to give a password on the command line as in -U user%pass.
-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.
+Last but not least net now always falls back to your local unix username if no
+-U is specified and a username is needed. net rpc commands will now prompt for a
+password unless one is specified using either -U user%pass or -A auth_file
-The Samba Wiki at http://wiki.samba.org should detail some of these
-development plans.
