Re: We are using the Cisco ACS 5.3 as a RADIUS for database authentication and authorization. The purpose is to authenticate incoming users based on the NAS-PORT-ID. The problem is that we cannot find any solution for the Service Router (Alcatel 7750) to send the NAS-PORT-ID to act as USERNAME. The username field is set to the MAC address. The ACS requires a USERNAME and there is not a way to manipulate the User-Name value once it is received. We heard that it could be possible to use the freeradius to act as a proxy for the Cisco secure ACS. This is what we want: User --> [SR] --> User-Name = “MAC:xx.xx.xx.xx” Password = “secret” NAS-Port-Id = 1/1/4.1001.129 --> [FR] --> User-Name = “1/1/4.1001.129” Password = “secret” --> [ACS 5.3] Is there a solution for this option in the Freeradius? Is there a way to manipulate the User-Name sent from the service router, (MA =?UTF-8?Q?C_address), __and_change_it_to_its_NAS-Port-Id_before_it_reaches?= the ACS RADIUS with help from the freeradius acting as a proxy?
