Delegation in Kerberos appears to be only a single hop mechanism. Does 
anyone want to comment on whether this is totally true.  It appears
to me, that is possible to use forwardable tickets to give a form
of multi-hop delegatiob, but this is does not restrict the priveleges
and so is a poor option.

On reading the RFC it says that the TGS issues a ticket on request
that can be sent to a proxy, but is not a TGS ticket, so from that I 
believe the proxy application cannot use the proxy in a second hop.

Comments?
