Ah, there is your problem. IPrincipal does not promise to implement 
"getLogin". In fact, the login name is commonly well-protected for security 
reasons.

Because if you have several different principal folders they might duplicate 
principal names (local ids). The prefix helps to distinguish between the 
various principal folders.
