Subject: [PATCH] Hide AccountLocked exception from end users

This change hides the AccountLocked exception from being returned
to the end user to hide sensitive information that a potential
malicious person could gain insight from.

The notification handler catches the AccountLocked exception as
before, but after sending the audit notification, it instead
bubbles up Unauthorized rather than AccountLocked.
