When evaluating authentication plugins, stop further evaluation
once the first failure is detected.
Implementation notes: Refactoring from a switch-case to an
if-else block allows the break statement to break out of the
outer for loop without additional control variables. Also,
moving the pr->n setting to within the loop keeps the value
correct if one does break out early.
First email patch submission and first patch submitted to this
list; be gentle please... -- Pete
