NEW FEATURES/CHANGES
====================
-Support for LDAP_SERVER_NOTIFICATION_OID
-----------------------------------------
-
-The ldap server has support for the LDAP_SERVER_NOTIFICATION_OID
-control. This can be used to monitor the active directory database
-for changes.
-
-VLV - Virtual List View
------------------------
-
-The VLV Control allows applications to page the LDAP directory in the
-way you might expect a live phone book application to operate, without
-first downloading the entire directory.
-
-DRS Replication for the AD DC
------------------------------
-
-DRS Replication in Samba 4.5 is now much more efficient in handling
-linked attributes, particularly in large domains with over 1000 group
-memberships or other links.
-
-Replication is also much more reliable in the handling of tree
-renames, such as the rename of an organizational unit containing many
-users. Extensive tests have been added to ensure this code remains
-reliable, particularly in the case of conflicts between objects added
-with the same name on different servers.
-
-Schema updates are also handled much more reliably.
-
-replPropertyMetaData Changes
-----------------------------
-
-During the development of the DRS replication, tests showed that Samba
-stores the replPropertyMetaData object incorrectly. To address this,
-be aware that dbcheck will now detect and offer to fix all objects in
-the domain for this error.
-
-Linked attributes on deleted objects
-------------------------------------
-
-In Active Directory, an object that has been tombstoned or recycled
-has no linked attributes. However, Samba incorrectly maintained such
-links, slowing replication and run-time performance. dbcheck now
-offers to remove such links, and they are no longer kept after the
-object is tombstoned or recycled.
-
-Improved AD DC performance
---------------------------
-Many other improvements have been made to our LDAP database layer in
-the AD DC, to improve performance, both during samba-tool domain
-provision and at runtime.
+net ads setspn
+---------------
-Other dbcheck improvements
---------------------------
+There is a new 'net ads setspn' sub command for managing Windows SPN(s)
+on the AD. This command aims to give the basic functionaility that is
+provided on windows by 'setspn.exe' e.g. ability to add, delete and list
+Windows SPN(s) stored in a Windows AD Computer object.
- - samba-tool dbcheck can now find and fix a missing or corrupted
- 'deleted objects' container.
- - BUG 11433: samba-dbcheck no longer offers to resort auxiliary class values
- in objectClass as these were then re-sorted at the next dbcheck indefinitely.
+The format of the command is:
-Tombstone Reanimation
----------------------
+net ads setspn list [machine]
+net ads setspn [add | delete ] SPN [machine]
-Samba now supports tombstone reanimation, a feature in the AD DC
-allowing tombstones, that is objects which have been deleted, to be
-restored with the original SID and GUID still in place.
+'machine' is the name of the computer account on the AD that is to be managed.
+If 'machine' is not specified the name of the 'client' running the command
+is used instead.
-Multiple DNS Forwarders on the AD DC
-------------------------------------
+The format of a Windows SPN is
+ 'serviceclass/host:port/servicename' (servicename and port are optional)
-Multiple DNS forwarders are now supported on the AD DC, allowing
-samba to fall back between two different DNS servers for forwarded queries.
+serviceclass/host is generally sufficient to specify a host based service.
-Password quality plugin support in the AD DC
---------------------------------------------
-
-The check password script now operates correctly in the AD DC (this
-was silently ignored in past releases)
+net ads keytab changes
+----------------------
+net ads keytab add no longer attempts to convert the passed serviceclass
+(e.g. nfs, html etc.) into a Windows SPN which is added to the Windows AD
+computer object. By default just the keytab file is modified.
-pwdLastSet is now correctly honoured
-------------------------------------
+A new keytab subcommand 'add_update_ads' has been added to preserve the
+legacy behaviour. However the new 'net ads setspn add' subcommand should
+really be used instead.
-BUG 9654: the pwdLastSet attribute is now correctly handled (this previously
-permitted passwords that next expire).
+net ads keytab create no longer tries to generate SPN(s) from existing
+entries in a keytab file. If it is required to add Windows SPN(s) then
+'net ads setspn add' should be used instead.
-net ads dns unregister
-----------------------
+REMOVED FEATURES
+================
-It is now possible to remove the DNS entries created with 'net ads register'
-with the matching 'net ads unregister' command.
-Samba-tool improvements
-------------------------
-Running samba-tool on the command line should now be a lot snappier. The tool
-now only loads the code specific to the subcommand that you wish to run.
+smb.conf changes
+================
+As the most popular Samba install platforms (Linux and FreeBSD) both
+support extended attributes by default, the parameters "map readonly",
+"store dos attributes" and "ea support" have had their defaults changed
+to allow better Windows fileserver compatibility in a default install.
+ Parameter Name Description Default
+ -------------- ----------- -------
+ map readonly Default changed no
+ store dos attributes Default changed yes
+ ea support Default changed yes
-REMOVED FEATURES
-================
+VFS interface changes
+=====================
-only user and username parameters
----------------------------------
-These two parameters have long been deprecated and superseded by
-"valid users" and "invalid users".
+The VFS ABI interface version has changed to 39. Function changes
+are:
-smb.conf changes
-----------------
+SMB_VFS_FSYNC: Removed: Only async versions are used.
+SMB_VFS_READ: Removed: Only PREAD or async versions are used.
+SMB_VFS_WRITE: Removed: Only PWRITE or async versions are used.
+SMB_VFS_CHMOD_ACL: Removed: Only CHMOD is used.
+SMB_VFS_FCHMOD_ACL: Removed: Only FCHMOD is used.
- Parameter Name Description Default
- -------------- ----------- -------
- only user Removed
- username Removed
+Any external VFS modules will need to be updated to match these
+changes in order to work with 4.9.x.
