Expiration Feature / Session-Timeout Problem

What all Attributes are supported depends on the NAS implementation. So
there could be some session terminal attribute supported by your NAS, if
you are using chillispot you have option to
return WISPr-Session-Terminate-Time. Chillspot then just terminates user
session at the timestamp returned by radius
(as WISPr-Session-Terminate-Time).

In any case if you want to not use (or selectively return Session-Timeout)
then you can do it in unlang. Like you can keep a list of MAC addresses
(for which Session-Timeout will be returned) in sql table and do a lookup.
If lookup returns true then add Session-Timeout to your reply else dont.
