UPGRADING
NEW FEATURES/CHANGES
====================
-Using x86_64 Accelerated AES Crypto Instructions
-================================================
-Samba on x86_64 can now be configured to use the Intel accelerated AES
-instruction set, which has the potential to make SMB3 signing and
-encryption much faster on client and server. To enable this, configure
-Samba using the new option --accel-aes=intelaesni.
+net ads setspn
+---------------
-This is a temporary solution that is being included to allow users
-to enjoy the benefits of Intel accelerated AES on the x86_64 platform,
-but the longer-term solution will be to move Samba to a fully supported
-external crypto library.
+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.
-The third_party/aesni-intel code will be removed from Samba as soon as
-external crypto library performance reaches parity.
+The format of the command is:
-The default is to build without setting --accel-aes, which uses the
-existing Samba software AES implementation.
+net ads setspn list [machine]
+net ads setspn [add | delete ] SPN [machine]
-KDC GPO application
--------------------
+'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.
-Adds Group Policy support for the samba kdc. Applies password policies
-(minimum/maximum password age, minimum password length, and password
-complexity) and kerberos policies (user/service ticket lifetime and
-renew lifetime).
+The format of a Windows SPN is
+ 'serviceclass/host:port/servicename' (servicename and port are optional)
-Adds the samba_gpoupdate script for applying and unapplying
-policy. Can be applied automatically by setting
+serviceclass/host is generally sufficient to specify a host based service.
- 'server services = +gpoupdate'.
+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.
-smb.conf changes
-================
-
- Parameter Name Description Default
- -------------- ----------- -------
- oplock contention limit Removed
-
-NT4-style replication based net commands removed
-================================================
+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.
-The following commands and sub-commands have been removed from the
-"net" utility:
+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 rpc samdump
-net rpc vampire ldif
-
-Also, replicating from a real NT4 domain with "net rpc vampire" and
-"net rpc vampire keytab" has been removed.
+REMOVED FEATURES
+================
-The NT4-based commands were accidentially broken in 2013, and nobody
-noticed the breakage. So instead of fixing them including tests (which
-would have meant writing a server for the protocols, which we don't
-have) we decided to remove them.
-For the same reason, the "samsync", "samdeltas" and "database_redo"
-commands have been removed from rpcclient.
-"net rpc vampire keytab" from Active Directory domains continues to be
-supported.
+smb.conf changes
+================
-vfs_aio_linux module removed
-============================
+ Parameter Name Description Default
+ -------------- ----------- -------
-The current Linux kernel aio does not match what Samba would
-do. Shipping code that uses it leads people to false
-assumptions. Samba implements async I/O based on threads by default,
-there is no special module required to see benefits of read and write
-request being sent do the disk in parallel.
