  Unfortunately, that's not how RADIUS works.  The documents have a
number of SHOULD and SHOULD NOT statements.  These make the specs very

  The documents are also *silent* on a number of subjects.  This makes
certain insane behavior "allowed", because it's not forbidden.  :(

  As for the Class attribute, pretty much every NAS vendor supports one,
and only one Class attribute.  If you're lucky, they support more than 8
bytes for Class.  Asking anyone to support multiple Class attributes is
probably a waste of time.

  Most of the RADIUS space is absurd.

  To be honest, there's probably another way to solve the problem you're
seeing.  Describe it in detail, and we may be able to help you.
