> James uses binary operation code in order to store user's ACL on a single int.
> This was buggy as a or was used to see if the user have a given right. A and
> should have been used.
> So, as a consequence, setting any write to a user gives him full rights on
> the given mailbox, wich is a major security issue.
> All mailbox implementations are affected.
