Outbound response to SP

Hi folks, I hope someone can point me in the right direction on this one.. My BB provider advises me that I am still sending them incorrect information in the outbound response when I authenticate a user, but are unable (so far) to tell me what it is that¹s incorrect. This is the info that they have requested I send them as part of the users response; Tunnel-Type = L2TP Tunnel-Medium-Type = IP Service-Type = Framed-User Tunnel-Password = XXXXXXX Tunnel-Server-Endpoint = IP of your LNS Tunnel-Client-Auth-ID = YYYYYYY I am getting authentication success on FR but at the client its still rejected. TIA! Kind Regards, Neil
