+Samba4 alpha11 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.

Directory domain, Samba4 is happier as a domain controller, and it is
in this role where it has seen deployment into production.
We are aiming for Samba 4 to be powerful frontend to large
directories.
-CHANGES SINCE Alpha5
+CHANGES SINCE alpha10
=====================
-In the time since Samba4 Alpha5 was released in June 2008, Samba has
-continued to evolve, but you may particularly notice these areas
-(in no particular order):
+Since the alpha10 release, we have fixed a number of serious bugs in
+the implementation of AD-compatible 'Directory Replication Services'.
+We can now join an AD domain as a read-write DC
- The source code for various libraries that are used by both Samba 3 and
- Samba 4 are now shared between the two rather than duplicated
- (and being slightly diverged).
+Importantly, since alpha10, the following serious issues were
+addressed:
+ - We now allocate RID values safely (previous implementations would
+ add users and groups without regard to allocated RID pools, possibly
+ creating duplicates)
+ - In previous Samba4 versions, a failure to 'prepare' a transaction
+ would silently commit the transaction.
- The tevent library has been split out and is now usable on its own.
-
- Several crash bugs and memory leaks in the registry library have been fixed.
-
- The Python modules have been extended and are no longer generated using SWIG.
-
- Stream renames are now supported.
-
- The provision script now has an interactive mode.
-
- The (broken) copy of CTDB has been removed.
-
- More work towards supporting an OpenLDAP backend.
-
- Initial work on using the Microsoft LDAP schema.
-
- The storage of schemas in LDB is now much more efficient.
-
- Support for extended DNs in LDB has been added.
-
- Incoming trusts are now supported.
-
- Compatibility of the registry server with several Windows versions has been
- improved.
-
- Improvements to LSA.idl for better functionality in the usrmgr.exe.
-
- Improved handling of non-standard characters in passwords.
-
- The embedded JavaScript library has been removed in favor of Python.
-
- The WMI implementation has been re-added, but does not completely work yet.
-
- xpress compression is now supported in the NDR layer.
-
- The main binary is now named "samba" rather than "smbd".
-
- A simple script for setting the expiration of a user was added.
-
- It is now possible to use the system-installed Heimdal using the
- experimental --enable-external-heimdal option to configure.
-
- The LDB library is now completely asynchronous internally.
-
- Various unknowns and correctness issues in the drsblobs and drsuapi RPC
- interface implementations have been fixed.
-
- It is now possible to connect to an LDAP backend using SASL credentials.
-
- Multi-fragment NTtrans request support has been added.
-
- The DCE/RPC server can now listen on a separate pipe to allow DCE/RPC
- connections forwarded from Samba 3. The user credentials are provided
- by the client.
-
- A large number of bugs in the SMB2 implementation have been fixed.
-
- Auxiliary classes in LDAP schema conversion are now collapsed.
-
-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.
+Any deployments of Samba4 before this alpha are very strongly
+encouraged to upgrade. Assistance may be found in the
+upgradeprovision script, and the advice of the Samba Team should be
+sought to determine the impact of these issues in your particular
+deployment.
+Our progress on DRS is being tracked in the Samba wiki:

CHANGES
=======
- 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
+ and server. (The NTP work in the previous alphas are partly to assist
with this problem).
-- Samba4 alpha6 is currently only portable to recent Linux
- distributions. Work to return support for other Unix varients is
- expected during the next alpha cycle
+- The DRS replication code often fails, and is very new
+
+- Users upgrading existing databases to Samba4 should carefully
+ consult upgrading-samba4.txt. We have made a number of changes in
+ this release that should make it easier to upgrade in future.
+ Btw: there exists also a script under the "setup" directory of the
+ source distribution called "upgrade_from_s3" which should allow a step-up
+ from Samba3 to Samba4. It's not included yet in the binary distributions
+ since it's completely experimental!
-- Samba4 alpha6 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).
+- ACL are not set by default on shares created by the provision.
+ Work is underway on this subject and it should be fixed in Alpha12.
