+ID Mapping
+----------
+We discovered that the majority of users have an invalid or incorrect
+ID mapping configuration. We implemented checks in the 'testparm' tool to
+validate the ID mapping configuration. You should run it and check if it prints
+any warnings or errors after upgrading! If it does you should fix them. See the
+'IDENTITY MAPPING CONSIDERATIONS' section in the smb.conf manpage.
+There are some ID mapping backends which are not allowed to be used for the
+default backend. Winbind will no longer start if an invalid backend is
+configured as the default backend.
+
+To avoid problems in future we advise all users to run 'testparm' after
+changing the smb.conf file!
