-What's new in Samba 4 beta3
-=============================
+Release Announcements
+=====================
-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.
+This is the first preview release of Samba 4.5. 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 4.5 will be the next version of the Samba suite.
-WARNINGS
-========
-Samba4 beta3 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'.
+UPGRADING
+=========
-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 beta at this stage.
+Nothing special.
-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.
-If you are upgrading, or looking to develop, test or deploy Samba 4.0
-beta releases, you should backup all configuration and data.
+NEW FEATURES/CHANGES
+====================
+Support for LDAP_SERVER_NOTIFICATION_OID
+----------------------------------------
-UPGRADING
-=========
+The ldap server has support for the LDAP_SERVER_NOTIFICATION_OID
+control. This can be used to monitor the active directory database
+for changes.
-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
+VLV - Virtual List View
+-----------------------
-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.
+The VLV Control allows applications to page the LDAP directory in the
+way you might expect a live phone book application to operate, without
+first downloading the entire directory.
+DRS Replication for the AD DC
+-----------------------------
-NEW FEATURES
-============
+DRS Replication in Samba 4.5 is now much more efficient in handling
+linked attributes, particularly in large domains with over 1000 group
+memberships or other links.
-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 beta2
-=====================
+Replication is also much more reliable in the handling of tree
+renames, such as the rename of an organizational unit containing many
+users. Extensive tests have been added to ensure this code remains
+reliable, particularly in the case of conflicts between objects added
+with the same name on different servers.
-For a list of changes since beta2, please see the git log.
+Schema updates are also handled much more reliably.
-$ git clone git://git.samba.org/samba.git
-$ cd samba.git
-$ git log samba-4.0.0beta2..samba-4.0.0beta3
+replPropertyMetaData Changes
+----------------------------
-Some major user-visible changes include:
+During the development of the DRS replication, tests showed that Samba
+stores the replPropertyMetaData object incorrectly. To address this,
+be aware that dbcheck will now detect and offer to fix all objects in
+the domain for this error.
-Samba now includes support for version 2.1 of the SMB protocol,
-the SMB2 version of Windows 7 and 2008R2, including dynamic
-reauthentication and support for multi-credit (large MTU).
-Consequently, Samba negotiates SMB 2.1 by default: The value "SMB2"
-for the configuration parameter "max protocol" has been changed to
-be an alias for SMB 2.1. Previously, the default SMB2 version of
-Samba was the original version 2.0 of SMB that was shipped with
-Windows Vista and 2008.
+Linked attributes on deleted objects
+------------------------------------
-Samba now offers basic experimental support for SMB3, the next version
-of the SMB protocol (formerly known as SMB 2.2) that will be available
-with Windows 8 and Windows Server 2012. Negotiation of SMB3 can be
-activated by setting "max protocol" to "SMB3" in smb.conf.
+In Active Directory, an object that has been tombstoned or recycled
+has no linked attributes. However, Samba incorrectly maintained such
+links, slowing replication and run-time performance. dbcheck now
+offers to remove such links, and they are no longer kept after the
+object is tombstoned or recycled.
+Improved AD DC performance
+--------------------------
-KNOWN ISSUES
-============
+Many other improvements have been made to our LDAP database layer in
+the AD DC, to improve performance, both during samba-tool domain
+provision and at runtime.
-- 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.
+Other dbcheck improvements
+--------------------------
-- 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 replicaton of
- this partition is not yet reliable.
+ - samba-tool dbcheck can now find and fix a missing or corrupted
+ 'deleted objects' container.
+ - BUG 11433: samba-dbcheck no longer offers to resort auxiliary class values
+ in objectClass as these were then re-sorted at the next dbcheck indefinitely.
-- Replication may fail on FreeBSD due to getaddrinfo() rejecting names
- containing _. A workaround will be in the next beta.
+Tombstone Reanimation
+---------------------
-- upgradeprovision should not be run when upgrading to this release
- from a recent release. No important database format changes have
- been made since alpha16.
+Samba now supports tombstone reanimation, a feature in the AD DC
+allowing tombstones, that is objects which have been deleted, to be
+restored with the original SID and GUID still in place.
-- Installation on systems without a system iconv (and developer
- headers at compile time) is known to cause errors when dealing with
- non-ASCII characters.
+Multiple DNS Forwarders on the AD DC
+------------------------------------
-- 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.
+Multiple DNS forwarders are now supported on the AD DC, allowing
+samba to fall back between two different DNS servers for forwarded queries.
-- There is no NetBIOS browsing support (network neighbourhood) in the
- 'samba' binary (use nmbd and smbd instead)
+Password quality plugin support in the AD DC
+--------------------------------------------
-- 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 check password script now operates correctly in the AD DC (this
+was silently ignored in past releases)
-- 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.
+pwdLastSet is now correctly honoured
+------------------------------------
+BUG 9654: the pwdLastSet attribute is now correctly handled (this previously
+permitted passwords that next expire).
-RUNNING Samba 4.0 as an AD DC
-=============================
+net ads dns unregister
+----------------------
-A short guide to setting up Samba 4 as an AD DC can be found on the wiki:
+It is now possible to remove the DNS entries created with 'net ads register'
+with the matching 'net ads unregister' command.
+
+
+
+REMOVED FEATURES
+================
+
+only user and username parameters
+---------------------------------
+These two parameters have long been deprecated and superseded by
+"valid users" and "invalid users".
+
+smb.conf changes
+----------------
+
+ Parameter Name Description Default
+ -------------- ----------- -------
+ only user Removed
+ username Removed
