  This solution is based on the fact that the !RevisionControler bypasses all checks if the user is "System". It might be better to introduce a parameter in the !ReservedCheckinAction class that would enable setting the identity or to set an override flag.

+ By default any user can change permissions to pages. This allows them to upgrade their capabilities on any page to either an editor or reviewer. This solution is from the user list:
+ 
+  * Assign admin group to the role of admin for your site tree
+  * In lenya/pubs/<your-pub>/config/ac/usecase-policies.xml add the following inside of the usecases tags: <usecase id="info-ac-authoring"><role id="admin"/></usecase>
+ 
+ Now, whenever a none admin tries to use the AC Auth page they will be prevented from doing so.
