-What's new in Samba 4 alpha19
+What's new in Samba 4.0 beta8
=============================
Samba 4.0 will be the next version of the Samba suite and incorporates
support for the Active Directory logon protocols used by Windows 2000
and above.

WARNINGS
========
-Samba4 alpha19 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'.
+Samba 4.0 beta8 is not a final Samba release, however we are now making
+good progress towards a Samba 4.0 release. However, this is expected to be the
+last beta release before we start on our release candidate series.
-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.
+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'.
-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.

+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
+
+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).
NEW FEATURES
============
-Samba 4.0 alpha supports the server-side of the Active Directory logon
+Samba 4.0 beta 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.
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
+Samba 4.0 beta ships with two distinct file servers. We now use the
+file server from the Samba 3.x series 'smbd' for all file serving by
+default.
+
+Samba 4.0 also ships with the 'NTVFS' file server. This file server
+is what was used in all previous alpha 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-coordinated by this
+master binary.
+
+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).
+
+To provide accurate timestamps to Windows clients, we integrate with
+the NTP project to provide secured NTP replies. To use you need to
+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:
-CVE-2012-1182:
- Samba 3.0.x to 3.6.3 are affected by a
- vulnerability that allows remote code
- execution as the "root" user.
-
-Portability to MacOS X. By using the CC_MD5*() routines we no longer
-segfault on MacOS X.
-
-The source4/librpc layer has been reworked to be much more robust to
-connection failures.
+- A fix for a segfault/abort on startup of the 'samba' binary in the
+ credentials_secrets code.
-security=share in smbd has now been removed.
+- A fix for samba-tool classicupgrade of pdb_ldap-based domains
-A segfault in vfs_aio_fork for the smbd file server has been fixed
+- A fix for samba-tool domain exportkeyab only exporting DES keys
-ldbadd and ldbmodify now handle each ldif file in a single
-transaction, when modifying a local ldb.
+- Printing is now enabled on the AD DC
-Further improvements to the dlz_bind9 and internal DNS servers.
+- Fix bug #9124 - Samba fails to set "inherited" bit on inherited ACE's.
+- We now avoid printing secret attributes (such as unicodePwd and
+ suppliementalCredentials) in ldb trace logs
-Some major but less visible changes include:
+- s3-printing: fix bug 9123 lprng job tracking errors
-Initial support for s3fs, using the smbd file server in the AD Domain
-controller has been added (but not yet finished, so not exposed)
+- A fix for building with MIT Kerberos
-Samba now only uses the _FILE_OFFSET_BITS=64 API for accessing large
-files, not the _LARGEFILE64_SOURCE API.
+KNOWN ISSUES
+============
-All Samba daemons now monitor stdin when launched in the foreground,
-and shutdown when stdin is closed. We also ensure that all child
-processes are clened up by a similar mechanism. This ensures that
-stray processes do not hang around, particularly in make test.
+- '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.
-Further preparation work for moving to TDB2, a new version of Samba's core TDB
-database.
+ 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.
-Early implementation work on the SMB 2.2 protocol client and server as
-the team improves and develops support these new protocols.
+- 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.
-The last of the old-style krb5 ticket handling has been removed.
+- 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.
+- Replication of DNS data from one AD server to another may not work.
+ The DNS data used by the internal DNS server and bind9_dlz is stored
+ in an application partition in our directory. The replication of
+ this partition is not yet reliable.
-KNOWN ISSUES
-============
+- Replication may fail on FreeBSD due to getaddrinfo() rejecting names
+ containing _. A workaround will be in a future beta.
- upgradeprovision should not be run when upgrading to this release
from a recent release. No important database format changes have
been made since alpha16.
-- The BIND 9 DLZ plugin is compatible only with BIND 9.8, not BIND 9.9.
-
-- Systems with tdb or ldb installed as a system library may have
- difficulty building this release of Samba4. The --disable-tdb2
- configure switch may be of assistance.
-
- 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 samba3upgrade tool
-
- 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)
+- There is no NetBIOS browsing support (network neighbourhood)
+ available for the AD domain controller. (Support in nmbd and smbd
+ for classic domains and member/standalone servers is unchanged).
- Clock Synchronisation is critical. Many 'wrong password' errors are
actually due to Kerberos objecting to a clock skew between client
experience issues with DRS replication, as we have fixed many issues
here in response to feedback from our production users.
