692 Release Notes for Samba 4.15.0
694 ==============================
697 This is the first stable release of the Samba 4.15 release series.
698 Please read the release notes carefully before upgrading.
701 Removed SMB (development) dialects
702 ==================================
704 The following SMB (development) dialects are no longer
705 supported: SMB2_22, SMB2_24 and SMB3_10. They are were
706 only supported by Windows technical preview builds.
707 They used to be useful in order to test against the
708 latest Windows versions, but it's no longer useful
709 to have them. If you have them explicitly specified
710 in your smb.conf or an the command line,
711 you need to replace them like this:
715 Note that it's typically not useful to specify
716 "client max protocol" or "server max protocol"
717 explicitly to a specific dialect, just leave
718 them unspecified or specify the value "default".

741 New minimum version for the experimental MIT KDC
742 ================================================
744 The build of the AD DC using the system MIT Kerberos, an
745 experimental feature, now requires MIT Kerberos 1.19. An up-to-date
746 Fedora 34 has this version and has backported fixes for the KDC crash
747 bugs CVE-2021-37750 and CVE-2021-36222
756 The effort to modernize Samba's VFS interface is complete and Samba 4.15.0 ships
757 with a modernized VFS designed for the post SMB1 world.
759 For details please refer to the documentation at source3/modules/The_New_VFS.txt
760 or visit the <https://wiki.samba.org/index.php/The_New_VFS>.
763 Bind DLZ: add the ability to set allow/deny lists for zone transfer clients
764 ---------------------------------------------------------------------------
766 Up to now, any client could use a DNS zone transfer request to the
767 bind server, and get an answer from Samba. Now the default behaviour
768 will be to deny those request. Two new options have been added to
769 manage the list of authorized/denied clients for zone transfer
770 requests. In order to be accepted, the request must be issued by a
771 client that is in the allow list and NOT in the deny list.
774 "server multi channel support" no longer experimental
775 -----------------------------------------------------
777 This option is enabled by default starting with 4.15 (on Linux and FreeBSD).
778 Due to dependencies on kernel APIs of Linux or FreeBSD, it's only possible
779 to use this feature on Linux and FreeBSD for now.
782 samba-tool available without the ad-dc
783 --------------------------------------
785 The 'samba-tool' command is now available when samba is configured
786 "--without-ad-dc". Not all features will work, and some ad-dc specific options
787 have been disabled. The 'samba-tool domain' options, for example, are limited
788 when no ad-dc is present. Samba must still be built with ads in order to enable
792 Improved command line user experience
793 -------------------------------------
795 Samba utilities did not consistently implement their command line interface. A
796 number of options were requiring to specify values in one tool and not in the
797 other, some options meant different in different tools.
799 These should be stories of the past now. A new command line parser has been
800 implemented with sanity checking. Also the command line interface has been
801 simplified and provides better control for encryption, signing and kerberos.
803 Previously many tools silently ignored unknown options. To prevent unexpected
804 behaviour all tools will now consistently reject unknown options.
806 Also several command line options have a smb.conf variable to control the
809 All tools are now logging to stderr by default. You can use "--debug-stdout" to
810 change the behavior. All servers will log to stderr at early startup until logging
811 is setup to go to a file by default.
816 --client-protection=off|sign|encrypt
819 --kerberos -> --use-kerberos=required|desired|off
820 --krb5-ccache -> --use-krb5-ccache=CCACHE
821 --scope -> --netbios-scope=SCOPE
822 --use-ccache -> --use-winbind-ccache
826 -C removed from --use-winbind-ccache
827 -i removed from --netbios-scope
831 ### Duplicates in command line utils
833 ldbadd/ldbdel/ldbedit/ldbmodify/ldbrename/ldbsearch:
834 -e is still available as an alias for --editor,
836 -s is no longer reported as an alias for --configfile,
837 it never worked that way as it was shadowed by '-s' for '--scope'.
840 -l is not available for --load-dso anymore
843 -l is not available for --long anymore
846 -V is not available for --viewsddl anymore
849 --user -> --quota-user
852 --log-stdout -> --debug-stdout
855 --log-stdout -> --debug-stdout
858 --log-stdout -> --debug-stdout
861 Scanning of trusted domains and enterprise principals
862 -----------------------------------------------------
864 As an artifact from the NT4 times, we still scanned the list of trusted domains
865 on winbindd startup. This is wrong as we never can get a full picture in Active
866 Directory. It is time to change the default value to "No". Also with this change
867 we always use enterprise principals for Kerberos so that the DC will be able
868 to redirect ticket requests to the right DC. This is e.g. needed for one way
869 trusts. The options `winbind use krb5 enterprise principals` and
870 `winbind scan trusted domains` will be deprecated in one of the next releases.
873 Support for Offline Domain Join (ODJ)
874 -------------------------------------
876 The net utility is now able to support the offline domain join feature
877 as known from the Windows djoin.exe command for many years. Samba's
878 implementation is accessible via the 'net offlinejoin' subcommand. It
879 can provision computers and request offline joining for both Windows
880 and Unix machines. It is also possible to provision computers from
881 Windows (using djoin.exe) and use the generated data in Samba's 'net'
882 utility. The existing options for the provisioning and joining steps
883 are documented in the net(8) manpage.
886 'samba-tool dns zoneoptions' for aging control
887 ----------------------------------------------
889 The 'samba-tool dns zoneoptions' command can be used to turn aging on
890 and off, alter the refresh and no-refresh periods, and manipulate the
891 timestamps of existing records.
893 To turn aging on for a zone, you can use something like this:
895 samba-tool dns zoneoptions --aging=1 --refreshinterval=306600
897 which turns on aging and ensures no records less than five years old
898 are aged out and scavenged. After aging has been on for sufficient
899 time for records to be renewed, the command
901 samba-tool dns zoneoptions --refreshinterval=168
903 will set the refresh period to the standard seven days. Using this two
904 step process will help prevent the temporary loss of dynamic records
905 if scavenging happens before their first renewal.
908 Marking old records as static or dynamic with 'samba-tool'
909 ----------------------------------------------------------
911 A bug in Samba versions prior to 4.9 meant records that were meant to
912 be static were marked as dynamic and vice versa. To fix the timestamps
913 in these domains, it is possible to use the following options,
914 preferably before turning aging on.
916 --mark-old-records-static
917 --mark-records-dynamic-regex
918 --mark-records-static-regex
920 The "--mark-old-records-static" option will make records older than the
921 specified date static (that is, with a zero timestamp). For example,
922 if you upgraded to Samba 4.9 in November 2018, you could use ensure no
923 old records will be mistakenly interpreted as dynamic using the
926 samba-tool dns zoneoptions --mark-old-records-static=2018-11-30
928 Then, if you know that that will have marked some records as static
929 that should be dynamic, and you know which those are due to your
930 naming scheme, you can use commands like:
932 samba-tool dns zoneoptions --mark-records-dynamic-regex='\w+-desktop'
934 where '\w+-desktop' is a perl-compatible regular expression that will
935 match 'bob-desktop', 'alice-desktop', and so on.
937 These options are deliberately long and cumbersome to type, so people
938 have a chance to think before they get to the end. You can make a
939 mess if you get it wrong.
941 All 'samba-tool dns zoneoptions' modes can be given a "--dry-run/-n"
942 argument that allows you to inspect the likely results before going
945 NOTE: for aging to work, you need to have "dns zone scavenging = yes"
946 set in the smb.conf of at least one server.
949 DNS tombstones are now deleted as appropriate
950 ---------------------------------------------
952 When all the records for a DNS name have been deleted, the node is put
953 in a tombstoned state (separate from general AD object tombstoning,
954 which deleted nodes also go through). These tombstones should be
955 cleaned up periodically. Due to a conflation of scavenging and
956 tombstoning, we have only been deleting tombstones when aging is
959 If you have a lot of tombstoned DNS nodes (that is, DNS names for
960 which you have removed all the records), cleaning up these DNS
961 tombstones may take a noticeable time.
964 DNS tombstones use a consistent timestamp format
965 ------------------------------------------------
967 DNS records use an hours-since-1601 timestamp format except for in the
968 case of tombstone records where a 100-nanosecond-intervals-since-1601
969 format is used (this latter format being the most common in Windows).
970 We had mixed that up, which might have had strange effects in zones
971 where aging was enabled (and hence tombstone timestamps were used).
974 samba-tool dns update and RPC changes
975 -------------------------------------
977 The dnsserver DCERPC pipe can be used by 'samba-tool' and Windows tools
978 to manipulate dns records on the remote server. A bug in Samba meant
979 it was not possible to update an existing DNS record to change the
980 TTL. The general behaviour of RPC updates is now closer to that of
983 'samba-tool dns update' is now a bit more careful in rejecting and
984 warning you about malformed IPv4 and IPv6 addresses.
986 CVE-2021-3671: Crash in Heimdal KDC and updated security release policy
987 -----------------------------------------------------------------------
989 An unuthenticated user can crash the AD DC KDC by omitting the server
990 name in a TGS-REQ. Per Samba's updated security process a specific
991 security release was not made for this issue as it is a recoverable
994 See https://wiki.samba.org/index.php/Samba_Security_Proces
996 samba-tool domain backup offline with the LMDB backend
997 ------------------------------------------------------
999 samba-tool domain backup offline, when operating with the LMDB backend
1000 now correctly takes out locks against concurrent modification of the
1001 database during the backup. If you use this tool on a Samba AD DC
1002 using LMDB, you should upgrade to this release for safer backups.
1007 Tru64 ACL support has been removed from this release. The last
1008 supported release of Tru64 UNIX was in 2012.
1010 NIS support has been removed from this release. This is not
1011 available in Linux distributions anymore.
1013 The DLZ DNS plugin is no longer built for Bind versions 9.8 and 9.9,
1014 which have been out of support since 2018.
