    Monitor the communicated data with a tcp tracer (e.g. TcpTrace by
    http://www.pocketsoap.com/tcpTrace/) on the client- and (!) server-side, to
    check if your exceptions get transmitted. Some weeks ago I observed, that if
    client and server are hosted by different machines, the exception got
    filtered at the server's boundary. TcpTrace on the server showed the
    exception, whereas TcpTrace on the client never saw any of this. NB:
    internals like a stacktrace shouldn't be published to clients, because of
    security reasons.
    If you are doing serverside authentication, you seem to have some custom
    authentication sinks - in this case you can simply use the response header
    to transfer status informations to the client (e.g. "AccessGranted" vs.
    "AccessDenied").

    Regards,
    Michael
