auth module: update for messagemapper changes

Since commit a993d1c358e24ab85621568c10411c5496e2dea8, the message
mappers have a more rational way of reporting failures, but the auth
module was not using it, resulting in the wrong permissions being
granted/revoked whenever allow/deny was being used.
