accounts. If the email address is not a cs.utah.edu address, then
  cross check the uid against the cslogins DB in /usr/testbed/etc.
  The DB is created with /users/stoller/cslogins.pl like this:

    ypcat passwd | awk -F : '{print $1}' | cslogins.pl cslogins

  This creates cslogins.db, which I then copied to /usr/testbed/etc.

  As soon as I get a clear idea of whether ypcat is going to work
  in the future, I will automate this part.
* Also added some sanity checking to make sure the email address looks
  reasonable (since I needed the domain anyway).
