UPGRADING
NEW FEATURES/CHANGES
====================
-The "strict sync" global parameter has been changed from
-a default of "no" to "yes". This means smbd will by default
-obey client requests to synchronize unwritten data in operating
-system buffers safely onto disk. This is a safer default setting
-for modern SMB1/2/3 clients.
-
-Authentication and Authorization audit support
-----------------------------------------------
-
-Detailed authentication and authorization audit information is now
-logged to Samba's debug logs under the "auth_audit" debug class,
-including in particular the client IP address triggering the audit
-line. Additionally, if Samba is compiled against the jansson JSON
-library, a JSON representation is logged under the "auth_json_audit"
-debug class.
-
-Audit support is comprehensive for all authentication and
-authorisation of user accounts in the Samba Active Directory Domain
-Controller, as well as the implicit authentication in password
-changes. In the file server and classic/NT4 domain controller, NTLM
-authentication, SMB and RPC authorization is covered, however password
-changes are not at this stage, and this support is not currently
-backed by a testsuite.

+net ads setspn
+---------------
+
+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 format of the command is:
+
+net ads setspn list [machine]
+net ads setspn [add | delete ] SPN [machine]
+
+'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.
+
+The format of a Windows SPN is
+ 'serviceclass/host:port/servicename' (servicename and port are optional)
+
+serviceclass/host is generally sufficient to specify a host based service.
+
+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.
+
+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.
+
+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.
+
+Local authorization plugin for MIT Kerberos
+-------------------------------------------
+
+This plugin controls the relationship between Kerberos principals and AD
+accounts through winbind. The module receives the Kerberos principal and the
+local account name as inputs and can then check if they match. This can resolve
+issues with canonicalized names returned by Kerberos within AD. If the user
+tries to log in as 'alice', but the samAccountName is set to ALICE (uppercase),
+Kerberos would return ALICE as the username. Kerberos would not be able to map
+'alice' to 'ALICE' in this case and auth would fail. With this plugin account
+names can be correctly mapped. This only applies to GSSAPI authentication,
+not for the geting the initial ticket granting ticket.
