+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

and above.

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

-However, we still recommend against upgrading production servers from

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' 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
============

issue.

file server from the Samba 3.x series 'smbd' for all file serving by

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.

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-ordinated by this

-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).

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.
-- 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. Recursivly giving 'domain administrators' write
- access to the contents of the sysvol share using a windows client
- will fix this in the interim.
-
- For similar reasons, sites with ACLs stored by the ntvfs file server
may wish to continue to use that file server implementation, as a
posix ACL will similarly not be set in this case.
