[LON-CAPA-admin] Kerberos?

It really should be as easy as getting krb5.conf set up on your library 
server. The other servers do not need the setup as your library server is 
the only one doing the authentication.

I use kinit to make sure the system is configured okay as far as the 
server is concerned. (kinit simply 'grabs a ticket' if it authenticates 
okay.) If kinit works, then LON-CAPA should be able to authenticate.

I don't think there are any mechanisms for changing logins once they are 
set. If you are really certain this is something you want to do, it 
probably wouldn't be too hard to write a script to do this, but you'd need 
to be pretty careful.
