Yes.

Yes and No. ACLs are authorization only; not authentication.

Yes. We're providing a channel for the application to do per-object
authorization, if it so wishes. Otherwise, there's also an ACL to set
access to the whole Web server, and that authorization is checked at
the transport layer we're providing by using DCE. For more details,
see the information at http://riwww.osf.org:8001

Yes, it has. Sorry, I was terse, because I know Phill knows all about
what we're doing. The DCE Web project is using DCE to provide a
transport to tunnel application data (in this case, HTTP) over RPC,
and it also uses DCE location-independant naming for server lookup,
and ACLs for authorization (as sketched above).
