+Bugfix: Fix the idm and settings extensions' admin user id configuration option
+
+We've fixed the admin user id configuration of the settings and idm extensions.
+The have previously only been configurable via the oCIS shared configuration and
+therefore have been undocumented for the extensions. This config option is now part
+of both extensions' configuration and can now also be used when the extensions are
+compiled standalone.
