Release Announcements
---------------------

This is the sixth 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/.

In this release candidate, we have a significant number of improvements
to our Access Control List (ACL) code, particularly for the Active
Directory Domain Controller, but also in our general purpose file
server.

These changes are important, as they enable Group Policy Objects to work
correctly, allow administrators to impose restrictions on some users
reading certain parts of the directory and correctly propagating
inherited ACLs down the LDAP directory tree.

Users of the Active Directory Domain Controller upgrading 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.

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 4.0.0rc5 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.

CHANGES SINCE 4.0.0rc4
======================

With this release candidate the location of the socket samba accepts
connections from NTPd has changed, as has the enforced permissions.

This means the ntp.conf will need to change from (eg)

ntpsigndsocket /usr/local/samba/var/run/ntp_signd/

to

ntpsigndsocket /usr/local/samba/var/lib/ntp_signd/

To use the socket with ntp on a system with an ntp user and group, you must
run:

chgrp ntp /usr/local/samba/var/lib/ntp_signd/

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.

  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.

- 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 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.
