Due to the design of the mobile network, the actual session is 
originated from the network rather than the device, which iirc presents 
only CHAP, but may or may not include a username/password pair and 
thusly the calling station id can include identifying info such as sim 
id or phone number

Using the Auth-Type method does work, but as the username is the lookup 
key,  it doesn't provide the ability to deliver attributes to the NAS 
(from what I can see), I ran into this exact issue when first looking at 
implementing it
