-What's new in Samba 4 alpha16
+What's new in Samba 4 alpha20
=============================
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.
+SECURITY RELEASE
+================
+
+This is a security release in order to address CVE-2012-2111
+(Incorrect permission checks when granting/removing privileges can
+compromise file server security).
+
+o CVE-2012-2111:
+ Samba 3.4.x to 3.6.4 are affected by a
+ vulnerability that allows arbitrary users
+ to modify privileges on a file server.
+
+This is in regards to the smbd file server, which is shipped in Samba
+4.0 alpha. The AD DC is not directly impacted, as the LSA
+implementation differs.
+
WARNINGS
========
-Samba4 alpha16 is not a final Samba release, however we are now making
+Samba4 alpha20 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'.
-No migration path is currently provided between these two sets of
-technology. These missing migration paths will be the focus of
-development between now and a Samba 4.0 release.
While binaries for the stable file server are provided in this
release, for a stable, supported file server, Samba3 domain or AD
internal workings of the DC code is now implemented in python.
-CHANGES SINCE alpha15
+CHANGES SINCE alpha19
=====================
-For a list of changes since alpha 15, please see the git log.
+For a list of changes since alpha 19, please see the git log.
$ git clone git://git.samba.org/samba.git
$ cd samba.git
-$ git log release-4-0-0alpha15..release-4-0-0alpha16
+$ git log samba-4.0.0alpha19..samba-4.0.0alpha20
+
+Some major user-visible changes include:
+
+Improvements to the 'samba-tool domain samba3upgrade' and
+samba_upgradedns tools
+
+Stability improvements in the Samba4 winbind implementation (that
+used in the AD DC mode).
-The biggest user-visible change is that binaries from the Samba 3.x
-series of development are now built and installed. These binaries
-(smbd, nmbd, winbindd, net, testparm, etc) operate much as they do in
-the Samba 3.6 release candidates.
+The BIND 9 DLZ plugin is now compatible with both BIND 9.8, and BIND 9.9.
-CHANGES
-=======
+dbcheck and runtime protection for the fSMORoleOwner attribute. This
+allows us to recover from a situation where the fSMORoleOwner is
+deleted.
-smb.conf changes
-----------------
+Support for storing the posixAccount and other auxiliary objectClass
+values (the values are not used by Samba as an AD DC at this stage,
+but may be used by clients).
- Parameter Name Description Default
- -------------- ----------- -------
- announce version Removed
- announce as Removed
-Those familiar with Samba 3 can find a list of user-visible changes
-between the two technology sets provided in the NEWS file.
+Some major but less visible changes include:
+
+Continued early implementation work on the SMB 2.2 protocol client and server as
+the team improves and develops support these new protocols.
+
+Initial work to build Samba using MIT kerberos in the top level waf
+build system. This is not complete at this time, but good progress is
+being made.
+
KNOWN ISSUES
============
+- upgradeprovision should not be run when upgrading to this release
+ from a recent release. No important database format changes have
+ been made since alpha16.
+
+- 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
- There is no printing support in the 'samba' binary (use smbd instead)
-- There is no NetBIOS browsing support in the 'samba' binary (use nmbd
- and 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
experience issues with DRS replication, as we have fixed many issues
here in response to feedback from our production users.
-- Users upgrading existing databases to Samba4 should carefully
- consult upgrading-samba4.txt. We have made a number of changes in
- this release that should make it easier to upgrade in future.
- Btw: there exists also a script under the "setup" directory of the
- source distribution called "upgrade_from_s3" which should allow a step-up
- from Samba3 to Samba4. It's not included yet in the binary distributions
- since it's completely experimental!
