> If jobhistory/job.* is filtered to bypass acl, resulting page will always 
> show Null user. This differs from 0.20 where filtering on this page, bypasses 
> security to allow all access to the page. essentially passes a null user to 
> AppController where an exception is thrown. If a null user is detected, we 
> should acl checking is disabled on this page.
