- Release Notes for Samba 3.2.0pre2
- Oct XX, 2007
- =================================
+Release Announcements
+=====================
-This is the second preview release of Samba 3.2.0. This is *not*
+This is the second release candidate of Samba 4.0. 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/.
-Please be aware that Samba is now distributed under the version 3
-of the new GNU General Public License. You may refer to the COPYING
-file that accompanies these release notes for further licensing details.
+Samba 4.0 will be the next version of the Samba suite and incorporates
+all the technology found in both the Samba4 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 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'.
+
+If you are upgrading, or looking to develop, test or deploy Samba 4.0
+releases candidates, you should backup all configuration and data.
+
+
+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).
+
+If you used the BIND9_FLATFILE or BIND9_DLZ features,
+you'll have to add '-dns' to the 'server services' option,
+as the internal dns server (SAMBA_INTERNAL) is the default now.
+
+
+NEW FEATURES
+============
+
+Samba 4.0 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 4.0.0rc2 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 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 two DNS
+solutions, a simple internal DNS server for 'out of the box' configurations
+and a more elaborate BIND plugin using the BIND DLZ mechanism in versions
+9.8 and 9.9. During the provision, you can select which backend to use.
+With the internal backend, your DNS server is good to go.
+If you chose the BIND_DLZ backend, a configuration file will be generated
+for bind to make it use this plugin, as well as a file explaining how to
+set up bind.
+
+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.

+======================
-Support for LanMan passwords is now disabled in both client and server
-applications. Additionally, clear text authentication requests are
-disabled by default in client utilities such as smbclient and all
-libsmbclient based applications. This will affect connection both
-to and from hosts running DOS, Windows 9x/ME, and OS/2. Please refer
-to the "Changes" section for details on the exact parameters that were
-updated.

+ blob.
+ * BUG 9213: Bad ASN.1 NegTokenInit packet can cause invalid free.
-Registry Configuration Backend

+KNOWN ISSUES
+============
+- '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.
-o Lars Mueller <lars@samba.org>
- * Makefile and build fixes.
- * Add pam_pwd_expire for pam_winbind (original patch from Andreas
- Schneider).
+ 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.
+- 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.
-o James Peach <jpeach@apple.com>
- * Fixes for setgroups() and *BSD and Darwin.
- * Support membership of >16 groups on Darwin.
+- 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.
-o Jiri Sasek <Jiri.Sasek@Sun.COM>
- * Added vfs_vfsacl module.
+- Replication may fail on FreeBSD due to getaddrinfo() rejecting names
+ containing _. A workaround will be in a future release.
+- samba_upgradeprovision should not be run when upgrading to this release
+ from a recent release. No important database format changes have
+ been made since alpha16.
-o Karolin Seeger <ks@sernet.de>
- * Add deletelocalgroup and unmapunixgroup subcommand to "net sam".
- * Cleanup internal passdb functions.
+- 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 its 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.
-o Simo Sorce <idra@samba.org>
- * Fixes for IDmap and Passdb backends.
+- 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
+ and server. (The NTP work in the previous alphas are partly to assist
+ with this problem).
-o Andrew Tridgell <tridge@samba.org>
- * Port ldb from the Samba 4 tree and add ldb group mapping plugin.
- * Move several file serving related tdb files to use the dbwrap
- API internally.
- * Cleanup the GPFS VFS plugin.
- * Experimental clustered file system support.
+- 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.
-o Jelmer Vernooij <jelmer@samba.org>
- * Implement NDR basic to support utilizing IDL files from Samba 4
- tree for general DCE/RPC parsing stubs.
