In amAuthentication.error [audit log] log of OpenAM, it does not log the UserID/LoginID if user is not found in the datastore. In other cases [invalid password/user locked] UserID/LoginID is being logged with proper message by OpenAM.
Current Behavior [ in case of "User not found"]
Expected Behavior [in case of "User not found"] with proper message.
In 13.x when new audit logging was introduced, non of the auth module will log username in failure case.
In 11.0.x and 12.0.x, LDAP auth module does not log the username in case user wasn't found.
