-What's new in Samba 4.0 beta4
-=============================
+Release Announcements
+=====================
+
+This is the second release candidate of Samba 4.0. 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 4.0 will be the next version of the Samba suite and incorporates
-all the technology found in both the Samba4 alpha series and the
+all the technology found in both the Samba4 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.

-Samba 4.0 beta4 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.

+This release contains the best of all of Samba's
technology parts, both a file server (that you can reasonably expect
to upgrade existing Samba 3.x releases to) and the AD domain
controller work previously known as 'samba4'.
-Samba 4.0 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 beta at this stage.
-
-In particular note that the new default configuration 's3fs' may have
-different stability characteristics compared with our previous default
-file server. We are making this release so that we can find and fix
-any of these issues that arise in the real world. New AD DC
-installations can provision or join with --use-ntvfs to obtain the
-previous default file server. See below how to continue using ntvfs
-in an existing installation.

If you are upgrading, or looking to develop, test or deploy Samba 4.0

UPGRADING
Users upgrading from Samba 3.x domain controllers and wanting to use
Samba 4.0 as an AD DC should use the 'samba-tool domain
classicupgrade' command. See the wiki for more details:
-https://wiki.samba.org/index.php/Samba4/samba3upgrade/HOWTO
+https://wiki.samba.org/index.php/Samba4/samba3upgrade/HOWTO.
-Users upgrading from Samba 4.0 alpha and beta releases since alpha15
-should run 'samba-tool dbcheck --cross-ncs --fix'. Users upgrading
-from earlier alpha releases should contact the team for advice.
+Users upgrading from Samba 4.0 alpha and beta releases since alpha15
+should run 'samba-tool dbcheck --cross-ncs --fix' before re-starting
+Samba. Users upgrading from earlier alpha releases should contact the
+team for advice.
+
+Users upgrading an AD DC from any previous release should run
+'samba-tool ntacl sysvolreset' to re-sync ACLs on the sysvol share
+with those matching the GPOs in LDAP and the defaults from an initial
+provision. This will set an underlying POSIX ACL if required (eg not
+using the NTVFS file server).
+
+If you used the BIND9_FLATFILE or BIND9_DLZ features,
+you'll have to add '-dns' to the 'server services' option,
+as the internal dns server (SAMBA_INTERNAL) is the default now.
NEW FEATURES
============
-Samba 4.0 beta supports the server-side of the Active Directory logon

join and domain logon operations with these clients.

issue.

Samba 4.0 also ships with the 'NTVFS' file server. This file server

+is what was used in all previous releases of Samba 4.0, and is
tuned to match the requirements of an AD domain controller. We
continue to support this, not only to provide continuity to
installations that have deployed it as part of an AD DC, but also as a
running example of the NT-FSA architecture we expect to move smbd to in
-the longer term.

-As mentioned above, this change to the default file server may cause
-instability, as we learn about the real-world interactions between
-these two key components.
-
-As DNS is an integral part of Active Directory, we also provide a DNS
-solution, using the BIND DLZ mechanism in versions 9.8 and 9.9.
-During the provision, a configuration file will be generated for bind
-to make it use this plugin. We also have a project to provide a
-minimal internal DNS server from within the Samba process, for easier
-'out of the box' configuration. Note however that this is not yet
-complete (pending addition of secure DNS update support).

+
+For pure file server work, the binaries users would expect from that
+series (nmbd, winbindd, smbpasswd) continue to be available. When
+running an AD DC, you only need to run 'samba' (not
+nmbd/smbd/winbind), as the required services are co-coordinated by this
+master binary.
+
+As DNS is an integral part of Active Directory, we also provide two DNS
+solutions, a simple internal DNS server for 'out of the box' configurations
+and a more elaborate BIND plugin using the BIND DLZ mechanism in versions
+9.8 and 9.9. During the provision, you can select which backend to use.
+With the internal backend, your DNS server is good to go.
+If you chose the BIND_DLZ backend, a configuration file will be generated
+for bind to make it use this plugin, as well as a file explaining how to
+set up bind.
To provide accurate timestamps to Windows clients, we integrate with

+start ntpd and configure it with the 'restrict ... ms-sntp' and
+ntpsigndsocket options.
Finally, 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.

-Some major user-visible changes include:
-
-- The issue with beta3 being unable to build with a released version of
- ldb has been resolved.
-
-- A new tool 'samba-tool domain dcpromo' has been added to allow the
- promotion of existing domain member accounts to a DC without creating
- a new SID
-
-- When provisioning with --use_rfc2307=yes we will populate the
- subtree CN=ypServ30,CN=RpcServices,CN=System,${DOMAINDN}. This makes
- it possible to manipulate the posix attributes via ADUC.
-
-- Improved 'samba-tool gpo' subcommands
-
-- --disable-ntdb now works properly
-
-- Bug 9026 - 3.6.6 upgrade from 3.5.x fails with "Couldn't migrate
- printers tdb file: NT_STATUS_NO_MEMORY" has been resolved
-
-- Bug 9016 - Connection to outbound trusted domain goes offline has
- been resolved
-
-Less visible, but important changes under the hood include:
-
-- Continued work to support SMB2 and SMB3
-
-- Correct restrictions and permissions on LSA calls over TCP and via
- Schannel have been implemented and tested
-
-- Continued work to use async IO to improve file server performance.
KNOWN ISSUES
============
+- 'samba-tool domain classicupgrade' will fail when setting ACLs on
+ the GPO folders with NT_STATUS_INVALID_ONWER in the default
+ configuration. This happens if, as is typical a 'domain admins'
+ group (-512) is mapped in the passdb backend being upgraded. This
+ is because the group mapping to a GID only prevents Samba from
+ allocating a uid for that group. The uid is needed so the 'domain
+ admins' group can own the GPO file objects.
+
+ To work around this issue, remove the 'domain admins' group before
+ upgrade, as it will be re-created automatically. You will
+ of course need to fill in the group membership again. A future release
+ will make this automatic, or find some other workaround.
+
- This release makes the s3fs file server the default, as this is the
file server combination we will use for the Samba 4.0 release.
- Users should still expect some rough edges: in particular, there are
- warnings about invalid parameters from the two respective parameter
- parsing engines.
-
-- Modifying of group policies by members of the Domain Administrators
- group is not possible with the s3fs file server, only with the ntvfs
- file server. This is due to the underlying POSIX ACL not being set
- at provision time.
- For similar reasons, sites with ACLs stored by the ntvfs file server
may wish to continue to use that file server implementation, as a
this partition is not yet reliable.
- Replication may fail on FreeBSD due to getaddrinfo() rejecting names
- containing _. A workaround will be in the next beta.

- Installation on systems without a system iconv (and developer

+- Domain member support in the 'samba' binary is in its infancy, and
is not comparable to the support found in winbindd. As such, do not
