It's even worse. All you're sure of getting is "authentication" (i.e. you know who you're talking to), but not necessarily "authorization" (i.e. what you are allowed to do). You might get authorization by using certificates as capabilities, but X.509 does not address such uses. All you can count on for "sure" is authentication. If you only get authentication you still another system for managing your authorization information (e.g. Athena's Moira Service Management System). -- Jon
