Yes. The idea here is that I want the directory to be protected but still
in AFS. To do this and allow the web server access, I must get credentials
to the web server process -- and that means creating a principal and pt
entry for the webserver, and starting the web server so that it can use
the principal and get a token.

Yes and no, not directly actually, I mean web browsers connecting to the
web server without having a Kerberos Ticket. They are unauthenticated
=66rom an AFS point of view, and they access the data over HTTP, but this
might actually be what the sysadmin wants ;-)
