Release Announcements
=====================
-This is the first preview release of Samba 4.8. This is *not*
+This is the first preview release of Samba 4.12. 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/.
-Samba 4.8 will be the next version of the Samba suite.
+Samba 4.12 will be the next version of the Samba suite.
UPGRADING
NEW FEATURES/CHANGES
====================
-KDC GPO application
--------------------
-Adds Group Policy support for the samba kdc. Applies password policies
-(minimum/maximum password age, minimum password length, and password
-complexity) and kerberos policies (user/service ticket lifetime and
-renew lifetime).
+GnuTLS 3.4.7 required
+---------------------
-Adds the samba_gpoupdate script for applying and unapplying
-policy. Can be applied automatically by setting
+Samba is making efforts to remove in-tree cryptographic functionality,
+and to instead rely on externally maintained libraries. To this end,
+Samba has chosen GnuTLS as our standard cryptographic provider.
- 'server services = +gpoupdate'.
+Samba now requires GnuTLS 3.4.7 to be installed (including development
+headers at build time) for all configurations, not just the Samba AD
+DC.
-smb.conf changes
-================
-
- Parameter Name Description Default
- -------------- ----------- -------
- binddns dir New
- gpo update command New
- oplock contention limit Removed
- prefork children New 1
-
-
-NT4-style replication based net commands removed
-================================================
-
-The following commands and sub-commands have been removed from the
-"net" utility:
-
-net rpc samdump
-net rpc vampire ldif
+NOTE WELL: The use of GnuTLS means that Samba will honour the
+system-wide 'FIPS mode' (a reference to the US FIPS-140 cryptographic
+standard) and so will not operate in many still common situations if
+this system-wide parameter is in effect, as many of our protocols rely
+on outdated cryptography.
-Also, replicating from a real NT4 domain with "net rpc vampire" and
-"net rpc vampire keytab" has been removed.
+A future Samba version will mitigate this to some extent where good
+cryptography effectively wraps bad cryptography, but for now that above
+applies.
-The NT4-based commands were accidentially broken in 2013, and nobody
-noticed the breakage. So instead of fixing them including tests (which
-would have meant writing a server for the protocols, which we don't
-have) we decided to remove them.
-For the same reason, the "samsync", "samdeltas" and "database_redo"
-commands have been removed from rpcclient.
-
-"net rpc vampire keytab" from Active Directory domains continues to be
-supported.
-
-vfs_aio_linux module removed
-============================
+REMOVED FEATURES
+================
-The current Linux kernel aio does not match what Samba would
-do. Shipping code that uses it leads people to false
-assumptions. Samba implements async I/O based on threads by default,
-there is no special module required to see benefits of read and write
-request being sent do the disk in parallel.
+BIND9_FLATFILE deprecated
+-------------------------
-smbclient reparse point symlink parameters reversed
-===================================================
+The BIND9_FLATFILE DNS backend is deprecated in this release and will
+be removed in the future. This was only practically useful on a single
+domain controller or under expert care and supervision.
-A bug in smbclient caused the 'symlink' command to reverse the
-meaning of the new name and link target parameters when creating a
-reparse point symlink against a Windows server. As this is a
-little used feature the ordering of these parameters has been
-reversed to match the parameter ordering of the UNIX extensions
-'symlink' command. The usage message for this command has also
-been improved to remove confusion.
+This release removes the "rndc command" smb.conf parameter, which
+supported this configuration by writing out a list of DCs permitted to
+make changes to the DNS Zone and nudging the 'named' server if a new
+DC was added to the domain. Administrators using BIND9_FLATFILE will
+need to maintain this manually from now on.
-REMOVED FEATURES
+smb.conf changes
================
-The two commands "net serverid list" and "net serverid wipe" have been
-removed, because the file serverid.tdb is not used anymore.
-
-"net serverid list" can be replaced by listing all files in the
-subdirectory "msg.lock" of Samba's "lock directory". The unique id
-listed by "net serverid list" is stored in every process' lockfile in
-"msg.lock".
+ Parameter Name Description Default
+ -------------- ----------- -------
-"net serverid wipe" is not necessary anymore. It was meant primarily
-for clustered environments, where the serverid.tdb file was not
-properly cleaned up after single node crashes. Nowadays smbd and
-winbind take care of cleaning up the msg.lock and msg.sock directories
-automatically.
+ nfs4:acedup Changed default merge
+ rndc command Removed
