What's new in Samba 4 alpha16
|
|
=============================
|
|
|
|
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
|
|
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.
|
|
|
|
WARNINGS
|
|
========
|
|
|
|
Samba4 alpha16 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
|
|
domain member installation, please run a Samba 3.x release, as we are
|
|
still bedding down the new single build system.
|
|
|
|
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.
|
|
|
|
If you are upgrading, or looking to develop, test or deploy Samba 4.0
|
|
alpha releases, you should backup all configuration and data.
|
|
|
|
NEW FEATURES
|
|
============
|
|
|
|
Samba 4.0 alpha 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.
|
|
|
|
Our Domain Controller (DC) implementation includes our own built-in
|
|
LDAP server and Kerberos Key Distribution Center (KDC) as well as the
|
|
Samba3-like logon services provided over CIFS. We correctly generate
|
|
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
|
|
internal workings of the DC code is now implemented in python.
|
|

CHANGES SINCE alpha15
|
|
=====================
|
|
|
|
For a list of changes since alpha 15, 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
|
|
|
|
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.

KNOWN ISSUES
|
|
============
|
|
|
|
- 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 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
|
|
and server. (The NTP work in the previous alphas are partly to assist
|
|
with this problem).
|
|
|
|
- The DRS replication code may fail. Please contact the team if you
|
|
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!
