Subject: pac responder: add user principal and name alias to cached user
 object

The principal name for the user is generated with the user name and the
domain from the PAC. It is stored in the cache so that if e.g. can be
used by password authentication. Additionally the name alias is stored
to allow case-insensitive searches.
