Hi:
Thanks for the rapid reply.
Is there another way to do the same thing? That is, provide some form of
authentication for the requests for host/service certificates, while keeping
the request of user certificates open.
Or maybe I am thinking about it all wrong, and there are completely
different (better?) ways of doing the same thing.
