Hello Paul,

as long as there is a path of trust between all parties - this should work.

Make sure that Kerberos is used between browser and web server, e.g. by inspecting
the security log - you should see a log on event for the client - the authentication
package has to be Kerberos (instead of NTLM) - or use a sniffer like www.ethereal.com
so see if Kerberos Service Ticket Requests are being made. For delegation
to work you need Kerb auth all the way through.
