    Let me see what I can figure out.  That's essentially what it was before, 
and only the username was returned.  When this transitioned to also providing a 
password I re-arranged things so that it would be a little more 
straight-forward to retrieve both the username and the password from the 
AttributePrincipal object without having to try to pass a HashMap or something 
like that.  If you have a direction in mind let me know...otherwise I'll just 
take a stab at something and see what I can figure out.
