Freeradius with Caller-station-id

[Richard J Palmer]

Hi we have several FreeRadius servers talking in our case to SM SQL and 
these work fine for all our users logging in using Username & passwords.

We are just getting a new L2TP link in and with sessions on this link I 
want to auhenticate *just* on the calling station ID - there will be a 
username/password BUT these are not what we need. I therefore want to be 
able to keep username/password for the current sessions, BUT if these 
fail authenticate on callingtation ID and return IP address details, etc.

is there a way to do this ? I worked round it previously by hacking the 
code BUT I'm sure there is a better way here...
