  That's what a RADIUS server does.

  Specific authentication methods allow for Access-Challenges.  If
you're not using one of those methods, you won't get Access-Challenges.

  You're trying to solve one problem, but not saying what it is.  You've
somehow convinced yourself that Access-Challenges are the solution to
that problem. So you're asking questions about that instead.

  What, exactly, is the problem, and why do you think Access-Challenges
are the solution?
