That's correct. OpenID, in a vacuum, is a fine mechanism. It's the  
way people are doing authentication to their OpenID IDPs on the wider  
Internet that's problematic and dangerous; we can generally avoid the  
issues entirely by authenticating transparently to the school server  
in the background.
