622 Release Notes for Samba 4.10.0
624 ==============================
627 This is the first stable release of the Samba 4.10 release series.
628 Please read the release notes carefully before upgrading.
637 A new 'samba-tool gpo backup' command has been added that can export a
638 set of Group Policy Objects from a domain in a generalised XML format.
640 A corresponding 'samba-tool gpo restore' command has been added to
641 rebuild the Group Policy Objects from the XML after generalization.
642 (The administrator needs to correct the values of XML entities between
643 the backup and restore to account for the change in domain).
648 The KDC now supports the pre-fork process model and worker processes will be
649 forked for the KDC when the pre-fork process model is selected for samba.
651 Prefork 'prefork children'
652 --------------------------
654 The default value for this smdb.conf parameter has been increased from 1 to
660 DCERPC now supports pre-forked NETLOGON processes. The netlogon processes are
661 pre-forked when the prefork process model is selected for samba.
663 Offline domain backups
664 ----------------------
666 The 'samba-tool domain backup' command has been extended with a new 'offline'
667 option. This safely creates a backup of the local DC's database directly from
668 disk. The main benefits of an offline backup are it's quicker, it stores more
669 database details (for forensic purposes), and the samba process does not have
670 to be running when the backup is made. Refer to the samba-tool help for more
671 details on using this command.
673 Group membership statistics
674 ---------------------------
676 A new 'samba-tool group stats' command has been added. This provides summary
677 information about how the users are spread across groups in your domain.
678 The 'samba-tool group list --verbose' command has also been updated to include
679 the number of users in each group.
681 Paged results LDAP control
682 --------------------------
684 The behaviour of the paged results control (1.2.840.113556.1.4.319, RFC2696)
685 has been changed to more closely match Windows servers, to improve memory
686 usage. Paged results may be used internally (or is requested by the user) by
687 LDAP libraries or tools that deal with large result sizes, for example, when
688 listing all the objects in the database.
690 Previously, results were returned as a snapshot of the database but now,
691 some changes made to the set of results while paging may be reflected in the
692 responses. If strict inter-record consistency is required in answers (which is
693 not possible on Windows with large result sets), consider avoiding the paged
694 results control or alternatively, it might be possible to enforce restrictions
695 using the LDAP filter expression.
697 For further details see https://wiki.samba.org/index.php/Paged_Results
699 Prefork process restart
700 -----------------------
702 The pre-fork process model now restarts failed processes. The delay between
703 restart attempts is controlled by the "prefork backoff increment" (default = 10)
704 and "prefork maximum backoff" (default = 120) smbd.conf parameters. A linear
705 back off strategy is used with "prefork backoff increment" added to the
706 delay between restart attempts up until it reaches "prefork maximum backoff".
708 Using the default sequence the restart delays (in seconds) are:
709 0, 10, 20, ..., 120, 120, ...
711 Standard process model
712 ----------------------
714 When using the standard process model samba forks a new process to handle ldap
715 and netlogon connections. Samba now honours the 'max smbd processes' smb.conf
716 parameter. The default value of 0, indicates there is no limit. The limit
717 is applied individually to netlogon and ldap. When the process limit is
718 exceeded Samba drops new connections immediately.
723 This is the first release of Samba which has full support for Python 3.
724 Samba 4.10 still has support for Python 2, however, Python 3 will be used by
725 default, i.e. 'configure' & 'make' will execute using python3.
727 To build Samba with python2 you *must* set the 'PYTHON' environment variable
728 for both the 'configure' and 'make' steps, i.e.
729 'PYTHON=python2 ./configure'
730 'PYTHON=python2 make'
731 This will override the python3 default.
733 Alternatively, it is possible to produce Samba Python bindings for both
734 Python 2 and Python 3. To do so, specify '--extra-python=/usr/bin/python2'
735 as part of the 'configure' command. Note that python3 will still be used as
736 the default in this case.
738 Note that Samba 4.10 supports Python 3.4 onwards.
740 Future Python support
741 ---------------------
743 Samba 4.10 will be the last release that comes with full support for
744 Python 2. Unfortunately, the Samba Team doesn't have the resources to support
745 both Python 2 and Python 3 long-term.
747 Samba 4.11 will not have any runtime support for Python 2. This means if
748 you use Python 2 bindings it is time to migrate to Python 3 now.
750 If you are building Samba using the '--disable-python' option (i.e. you're
751 excluding all the run-time Python support), then this will continue to work
752 on a system that supports either python2 or python3.
754 Also note that Samba 4.11 will most likely only support Python 3.6 onwards.
759 Authentication messages now contain the Windows Event Id "eventId" and logon
760 type "logonType". The supported event codes and logon types are:
762 4624 Successful logon
763 4625 Unsuccessful logon
770 The version number for Authentication messages is now 1.1, changed from 1.0
772 Password change messages now contain the Windows Event Id "eventId", the
773 supported event Id's are:
774 4723 Password changed
777 The version number for PasswordChange messages is now 1.1, changed from 1.0
779 Group membership change messages now contain the Windows Event Id "eventId",
780 the supported event Id's are:
781 4728 A member was added to a security enabled global group
782 4729 A member was removed from a security enabled global group
783 4732 A member was added to a security enabled local group
784 4733 A member was removed from a security enabled local group
785 4746 A member was added to a security disabled local group
786 4747 A member was removed from a security disabled local group
787 4751 A member was added to a security disabled global group
788 4752 A member was removed from a security disabled global group
789 4756 A member was added to a security enabled universal group
790 4757 A member was removed from a security enabled universal group
791 4761 A member was added to a security disabled universal group
792 4762 A member was removed from a security disabled universal group
795 The version number for GroupChange messages is now 1.1, changed from 1.0. Also
796 A GroupChange message is generated when a new user is created to log that the
797 user has been added to their primary group.
799 The leading "JSON <message type>:" and source file prefix of the JSON formatted
800 log entries has been removed to make the parsing of the JSON log messages
801 easier. JSON log entries now start with 2 spaces followed by an opening brace
804 SMBv2 samba-tool support
805 ------------------------
807 On previous releases, some samba-tool commands would not work against a remote
808 DC that had SMBv1 disabled. SMBv2 support has now been added for samba-tool.
809 The affected commands are 'samba-tool domain backup|rename' and the
810 'samba-tool gpo' set of commands. Refer also bug #13676.
812 New glusterfs_fuse VFS module
813 -----------------------------
815 The new vfs_glusterfs_fuse module improves performance when Samba
816 accesses a glusterfs volume mounted via FUSE (Filesystem in Userspace
817 as part of the Linux kernel). It achieves that by leveraging a
818 mechanism to retrieve the appropriate case of filenames by querying a
819 specific extended attribute in the filesystem. No extra configuration
820 is required to use this module, only glusterfs_fuse needs to be set in
821 the "vfs objects" parameter. Further details can be found in the
822 vfs_glusterfs_fuse(8) manpage. This new vfs_glusterfs_fuse module does
823 not replace the existing vfs_glusterfs module, it just provides an
824 additional, alternative mechanism to access a Gluster volume.
829 MIT Kerberos build of the AD DC
830 -------------------------------
832 While not removed, the MIT Kerberos build of the Samba AD DC is still
833 considered experimental. Because Samba will not issue security
834 patches for this configuration, such builds now require the explicit
835 configure option: --with-experimental-mit-ad-dc
837 For further details see
838 https://wiki.samba.org/index.php/Running_a_Samba_AD_DC_with_MIT_Kerberos_KDC
843 The samba_backup script has been removed. This has now been replaced by the
844 'samba-tool domain backup offline' command.
846 SMB client Python bindings
847 --------------------------
849 The SMB client python bindings are now deprecated and will be removed in future
850 Samba releases. This will only affects users that may have used the Samba
851 Python bindings to write their own utilities, i.e. users with a custom Python
852 script that includes the line 'from samba import smb'.
857 Parameter Name Description Default
858 -------------- ----------- -------
859 prefork backoff increment Delay added to process restart 10 (seconds)
861 prefork maximum backoff Maximum delay for process between 120 (seconds)
862 process restart attempts
863 smbd search ask sharemode Name changed, old name was
864 "smbd:search ask sharemode"
865 smbd async dosmode Name changed, old name was
867 smbd max async dosmode Name changed, old name was
868 "smbd:max async dosmode"
869 smbd getinfo ask sharemode New: similar to "smbd search ask yes
870 sharemode" but for SMB getinfo
