Is it possible to allow a client or server, that doesn't have the Novell Client running (and thus not client trust either) to get through the Bordermanager?

I've got a Blackberry server which I want to allow to access HTTP, because if it can't then it means our ends users cant (they get the bordermanager 403 "forbidden" page.)

I made an access rule to allow HTTP to any URL, with the source IP that of the Blackberry server but it still brings up the authentication page when you go to browse to something.
