Release Announcements
|
|
=====================
|
|
|
|
This is the first preview release of Samba 4.10. 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 4.10 will be the next version of the Samba suite.

UPGRADING
|
|
=========
|
|
|
|
|
|
NEW FEATURES/CHANGES
|
|
====================
|
|
|
|
GPO Improvements
|
|
----------------
|
|
|
|
A new 'samba-tool gpo export' command has been added that can export a
|
|
set of Group Policy Objects from a domain in a generalised XML format.
|
|
|
|
A corresponding 'samba-tool gpo restore' command has been added to
|
|
rebuild the Group Policy Objects from the XML after generalization.
|
|
(The administrator needs to correct the values of XML entities between
|
|
the backup and restore to account for the change in domain).
|
|
|
|
kdc prefork
|
|
-----------
|
|
|
|
The KDC now supports the pre-fork process model and worker processes will be
|
|
forked for the KDC when the pre-fork process model is selected for samba.
|
|
|
|
prefork 'prefork children'
|
|
--------------------------
|
|
|
|
The default value for this smdb.conf parameter has been increased from 1 to
|
|
4.
|
|
|
|
netlogon prefork
|
|
----------------
|
|
|
|
DCERPC now supports pre-forked NETLOGON processes. The netlogon processes are
|
|
pre-forked when the prefork process model is selected for samba.
|
|
|
|
Offline domain backups
|
|
----------------------
|
|
|
|
The 'samba-tool domain backup' command has been extended with a new 'offline'
|
|
option. This safely creates a backup of the local DC's database directly from
|
|
disk. The main benefits of an offline backup are it's quicker, it stores more
|
|
database details (for forensic purposes), and the samba process does not have
|
|
to be running when the backup is made. Refer to the samba-tool help for more
|
|
details on using this command.
|
|
|
|
Group membership statistics
|
|
---------------------------
|
|
|
|
A new 'samba-tool group stats' command has been added. This provides summary
|
|
information about how the users are spread across groups in your domain.
|
|
The 'samba-tool group list --verbose' command has also been updated to include
|
|
the number of users in each group.
|
|
|
|
prefork process restart
|
|
-----------------------
|
|
|
|
The pre-fork process model now restarts failed processes. The delay between
|
|
restart attempts is controlled by the "prefork backoff increment" (default = 10)
|
|
and "prefork maximum backoff" (default = 120) smbd.conf parameters. A linear
|
|
back off strategy is used with "prefork backoff increment" added to the
|
|
delay between restart attempts up until it reaches "prefork maximum backoff".
|
|
|
|
Using the default sequence the restart delays (in seconds) are:
|
|
0, 10, 20, ..., 120, 120, ...
|
|
|
|
REMOVED FEATURES
|
|
================
|
|
|
|
MIT Kerberos build of the AD DC
|
|
-------------------------------
|
|
|
|
While not removed, the MIT Kerberos build of the Samba AD DC is still
|
|
considered experimental. Because Samba will not issue security
|
|
patches for this configuration, such builds now require the explicit
|
|
configure option: --with-experimental-mit-ad-dc
|
|
|
|
For further details see
|
|

|
|
|
|
samba_backup
|
|
------------
|
|
|
|
The samba_backup script has been removed. This has now been replaced by the
|
|
'samba-tool domain backup offline' command.
|
|
|
|
smb.conf changes
|
|
================
|
|
|
|
Parameter Name Description Default
|
|
-------------- ----------- -------
|
|
prefork backoff increment Delay added to process restart 10 (seconds)
|
|
between attempts.
|
|
prefork maximum backoff Maximum delay for process between 120 (seconds)
|
|
process restart attempts
|
