> in revision 1076596 in made some improvements in ImpersonationImpl removing
> the shortcut for "AdminPrincipal" which from my point of view is problematic.
> however, this introduced the following compatibility issue (detected by tom):
> while - according to my tests - a user is allowed to impersonate itself (jcr
> isn't totally clear about this but states that Session.impersonate is used to
> "[...] impersonate" another [...]" this was possible for the admin-user due
> to the shortcut mentioned above.
> in order not to break existing code relying on that special case, i would
> suggest to change the code accordingly.
