I have an BSSID enabled AP and all Vlan clients should be authenticated on one IAS Server. On the Server the Vlans should be mapped to different Remote-Access Policies. I was not able to find any command for the "aaa group server" configuration, that adds an attribute wich allows the server to select the correct Remote-Access Policy.
Does anyone know an answer (without using different source addresses for aaa request)
Not really understanding what you said. You want to authenticate certain users to a different policy? Usually with radius, once you hit a policy, you either pass or fail. You specify a certain NAS IP ADDRESS... this you cant get around.
