[RADIATOR] Calling-Station-Id

[MKS]

Hi list

I'm looking for a Authby module or a hook that can give out ip's on
the content on "Calling-Station-Id" attribute,

Basic process
  1) authenticate all users (we don't care about user and passwords)
  2) do a sql query on the Calling-Station-Id field
            the db would just contains two fields, calling-station-id
string and ip-address
  3) if a match is found in the db, the ip-address should be send in
the response as Framed-IP-Address
      else access-denied...

Does someone already have something like this available, before a
brush up my perl skills;)

Regards
MKS
