                   =============================
                   Release Notes for Samba 4.0.0
                         December 11, 2012
                   =============================

This is is the first stable release of Samba 4.0.

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'.

Major enhancements in Samba 4.0.0 include:

Active Directory services
=========================

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.

When running an AD DC, you only need to run 'samba' (not smbd/nmbd/winbindd),
as the required services are co-coordinated by this master binary.
The tool to administer the Active Directory services is called 'samba-tool'.

A short guide to setting up Samba 4 as an AD DC can be found on the wiki:

  http://wiki.samba.org/index.php/Samba4/HOWTO

File Services
=============

Samba 4.0.0 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 prior to the beta2 release 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 (smbd, nmbd, winbindd, smbpasswd) continue to be available.

DNS
===

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.

NTP
===

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.

Python Scripting Interface
==========================

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.

Known Issues
============

- 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 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.

- 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.

- 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).

- 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.

- Linux inotify will now only be supported on systems where glibc also supports
  it (for details, please refer to bug #8850).

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.
