* http_auth: authentication
*
* Rob McCool & Brian Behlendorf.
*
* Adapted to Apache by rst.
*
* dirkx - Added Authoritative control to allow passing on to lower
* modules if and only if the userid is not known to this
* module. A known user with a faulty or absent password still
* causes an AuthRequired. The default is 'Authoritative', i.e.
* no control is passed along.
