Cross realm and/or referral issue?

[Davalos, Jeff (STL-MOM)]

Hey everyone,

Is there way to configure Safari 3.x or 4.x or Firefox 3.x on Mac OS X Leopard so that the browser will request a service ticket for a web server that is located in an extranet forest?
Extranet forest trusts the internal forest.

Is there any configuration on the internal forest to enable Mac OS X Leopard to obtain a referral for this service ticket, if necessary? Perhaps an additional SPN is needed? It is helpful to note that Internet Explorer 7.x and 8.x as well as Firefox 3.x users on PCs in the internal forest are receiving service tickets for the web server in the extranet forest without issue.

Thank you all...

Jeff
