Ping, does anyone else have an opinion on this using the context of the service 
rather than the pam name of the service? I still think the context is more 
appropriate.

Also, if we do this I think we should get rid of the old way of having seusers 
since it isn't clear where to do seuser updates anymore and it isn't even noted 
which of these take precedence.
