  Yes, it is.  But you need to write the code to make it do that.  There
is no pre-packaged configuration saying "implement Access-Challenge here"

  All Access-Challenge scenarios are tied to pre-existing authentication
methods.  e.g. EAP, SecurID, etc.  If you're technical enough to
implement your own Access-Challenge method, you're technical enough to
*implement* your own Access-Challenge method.

  If you can't figure out how to implement Access-Challenge in the
server (hint: there are examples), then you don't need to implement it.
