As a side note, if the patch that I submitted isn't accepted, then
PW_ACCESS_CHALLENGE
should be added to the list of items giving a REJECT_RC in rc_send_server().

Per RFC 2865, section 4.4:

"If the NAS does not support challenge/response, it MUST treat an
 Access-Challenge as though it had received an Access-Reject
 instead."
