That sentence doesn't make any sense.

Yes, that should happen.

Ah... *that* is the explanation I was looking for. Saying things like
"the access challenge is returned by the pam module" is *very* confusing.
All I know is that I last tested the module with Access-Challenge a
long time ago... and it worked then.
I would suggest updating the module source to print out what it's
doing, and why. That will help you understand the decisions it's making.
