UPGRADING
NEW FEATURES/CHANGES
====================
-GPO Improvements
-----------------
+Default samba process model
+---------------------------
-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.
+The default for the --model argument passed to the samba executable has changed
+from 'standard' to 'prefork'. This means a difference in the number of samba
+child processes that are created to handle client connections. The previous
+default would create a separate process for every LDAP or NETLOGON client
+connection. For a network with a lot of persistent client connections, this
+could result in significant memory overhead. Now, with the new default of
+'prefork', the LDAP, NETLOGON, and KDC services will create a fixed number of
+worker processes at startup and share the client connections amongst these
+workers. The number of worker processes can be configured by the 'prefork
+children' setting in the smb.conf (the default is 4).
-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).
+Authentication Logging.
+-----------------------
-kdc prefork
------------
+Winbind now logs PAM_AUTH and NTLM_AUTH events, a new attribute "logonId" has
+been added to the Authentication JSON log messages. This contains a random
+logon id that is generated for each PAM_AUTH and NTLM_AUTH request and is passed
+to SamLogon, linking the windbind and SamLogon requests.
-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.
+The serviceDescription of the messages is set to "winbind", the authDescription
+is set to one of:
+ "PASSDB, <command>, <pid>"
+ "PAM_AUTH, <command>, <pid>"
+ "NTLM_AUTH, <command>, <pid>"
+where:
+ <command> is the name of the command makinmg the winbind request i.e. wbinfo
+ <pid> is the process id of the requesting process.
-prefork 'prefork children'
---------------------------
+The version of the JSON Authentication messages has been changed to 1.2 from 1.1
-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.
REMOVED FEATURES
================
+Web server
+----------
+
+As a leftover from work related to the Samba Web Administration Tool (SWAT),
+Samba still supported a Python WSGI web server (which could still be turned on
+from the 'server services' smb.conf parameter). This service was unused and has
+now been removed from Samba.
