depends on your NAR - you need to send back the correct return attributes -
eg use the users file, or populate the SQL radreply table with the things you need.

for example, a Cisco device would want the tunnel medium type, type and
private group id 

   Tunnel-Medium-Type = "IEEE-802"
   Tunnel-Type = "VLAN"
   Tunnel-Private-Group-Id = "100"

this would tell the NAS to put the user onto VLAN 100
