- Release Notes for Samba 3.2.x
- XX ##, 200Y
- ==============================
+What's new in Samba 4 alpha17
+=============================
+
+Samba 4.0 will be the next version of the Samba suite and incorporates
+all the technology found in both the Samba4 alpha series and the
+stable 3.x series. The primary additional features over Samba 3.6 are
+support for the Active Directory logon protocols used by Windows 2000
+and above.
+
+WARNINGS
+========
+
+Samba4 alpha17 is not a final Samba release, however we are now making
+good progress towards a Samba 4.0 release, of which this is a preview.
+Be aware the this release contains both the technology of Samba 3.6
+(that you can reasonably expect to upgrade existing Samba 3.x releases
+to) and the AD domain controller work previously known as 'samba4'.
+
+While binaries for the stable file server are provided in this
+release, for a stable, supported file server, Samba3 domain or AD
+domain member installation, please run a Samba 3.x release, as we are
+still bedding down the new single build system.
+
+Samba4 is subjected to an awesome battery of tests on an automated
+basis, we have found Samba 4.0 to be very stable in it's behavior.
+However, we still recommend against upgrading production servers from
+Samba 3.x release to Samba 4.0 alpha at this stage.
+
+If you are upgrading, or looking to develop, test or deploy Samba 4.0
+alpha releases, you should backup all configuration and data.
+
+NEW FEATURES
+============
+
+Samba 4.0 alpha 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.
+
+Samba 4.0 alpha ships with two distinct file servers. The file server
+from the Samba 3.x series is 'smbd', and works with the binaries users
+would expect from that series (nmbd, winbindd, smbpasswd).
+
+Samba 4.0 also ships with a new file server, which is tuned to match
+the requirements of an AD domain controller. Users should not use the
+file server in the 'samba' binary for non-DC related tasks.
+
+A new scripting interface has been added to Samba 4, allowing Python
+programs to interface to Samba's internals, and many tools and
+internal workings of the DC code is now implemented in python.
+
+
+CHANGES SINCE alpha16
+=====================
+
+For a list of changes since alpha 15, please see the git log.
+
+$ git clone git://git.samba.org/samba.git
+$ cd samba.git
+$ git log release-4-0-0alpha16..release-4-0-0alpha17
+
+Some major user-visible changes include:
+
+samba-tool dbcheck
+------------------
+
+We now have an fsck-like tool for Samba's internal sam.ldb database.
+Run samba-tool dbcheck after installation to check your database for
+self-consistency. Any database created with a previous Samba4 alpha
+will have a very large number of consistency errors, which this tool
+can fix.
+
+See also the -H option to point dbcheck at a different database to the
+default, and the --fix and --yes options to make changes and to not
+prompt about those changes.
+
+After upgrading Samba, it is suggested that you do the following:
+
+ - stop samba
+ - take a backup copy of your sam.ldb and sam.ldb.d/* database files
+ - run samba-tool dbcheck --cross-ncs --fix
+ - use 'all' to say yes to fixing each type of error found
+ - after it has finished, run dbcheck again to ensure it reports no
+ errors
+
+There will be a lot of errors fixed, particularly related to
+bad/missing GUID values. This is due to a bug in previous releases
+that left many objects with bad GUID values. These can all be fixed
+using dbcheck with steps above.
+
+
+New default paths
+-----------------
+
+The configure options for paths have changed again, and the
+--enable-fhs option has been reinstated. Packagers should attempt to
+first package Samba using:
+
+./configure --enable-fhs --prefix=/usr --sysconfdir=/etc --localstatedir=/var
+
+and only after examining the location Samba uses with these options
+should further changes be made. Existing packaging scripts are not
+expected to work unmodified, instead the Samba Team's aim is to
+simplify such scripts for the long term.
+
+samba-tool domain samba3upgrade
+-------------------------------
+
+The new samba-tool domain samba3upgrade command is a supported upgrade route from Samba
+3.x domain controllers to Samba 4.0 AD domain controllers. This
+provides a one-time migration of all users, domain members, passwords,
+groups, group members and account polcies.
+
+This tool is still under development and may fail when presented with
+an inconsistant Samba3 database (such as many LDAP configurations).
+We hope to improve the error handling and recovery in these
+situations, so please provide feedback using the samba-technical
+mailing list.
+
+KNOWN ISSUES
+============
+
+- Installation on systems without a system iconv (and developer
+ headers at compile time) is known to cause errors when dealing with
+ non-ASCII characters.
+
+- In some situations, group members may not be upgraded by the
+ samba-tool domain upgrade_from_s3 script
+
+- The samba-tool domain join script will not join Windows 2000 domains.
+
+- Domain member support in the 'samba' binary is in it's infancy, and
+ is not comparable to the support found in winbindd. As such, do not
+ use the 'samba' binary (provided for the AD server) on a member
+ server.
+
+- There is no printing support in the 'samba' binary (use smbd instead)
+
+- There is no NetBIOS browsing support (network neighbourhood) in the
+ 'samba' binary (use nmbd and smbd instead)
+
+- 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 alphas are partly to assist
+ with this problem).
+
+- The DRS replication code may fail. Please contact the team if you
+ experience issues with DRS replication, as we have fixed many issues
+ here in response to feedback from our production users.
