-What's new in Samba 4.0 beta4
-=============================
-
-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
-========
-
-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.
-Be aware the 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.
+Release Announcements
+=====================
-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.
+This is the first preview release of Samba 4.8. 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/.
-If you are upgrading, or looking to develop, test or deploy Samba 4.0
-beta releases, you should backup all configuration and data.
+Samba 4.8 will be the next version of the Samba suite.
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'. Users upgrading
-from earlier alpha releases should contact the team for advice.
-
-
-NEW FEATURES
-============
-
-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.
-
-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 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. For pure file server work, the binaries users would expect
-from that series (nmbd, winbindd, smbpasswd) continue to be available.
-
-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.
-
-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).
-
-To provide accurate timestamps to Windows clients, we integrate with
-the NTP project to provide secured NTP replies.
-
-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.
-
-
-CHANGES SINCE beta3
-=====================
-
-For a list of changes since beta3, please see the git log.
-
-$ git clone git://git.samba.org/samba.git
-$ cd samba.git
-$ git log samba-4.0.0beta3..samba-4.0.0beta4
-
-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.
+NEW FEATURES/CHANGES
+====================
-- Improved 'samba-tool gpo' subcommands
-- --disable-ntdb now works properly
+smb.conf changes
+================
-- 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
+ Parameter Name Description Default
+ -------------- ----------- -------
-- 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
============
-- 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
- 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.
-
-- Replication may fail on FreeBSD due to getaddrinfo() rejecting names
- containing _. A workaround will be in the next 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.
-
-- Installation on systems without a system iconv (and developer
- headers at compile time) is known to cause errors when dealing with
- non-ASCII characters.
-
-- 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 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
- 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.
