[jcifs] How to customize HTTP Status 401 Error message

[Richard Caper]

In jcifs.http.NtlmSsp, you can add the following at the bottom:

    resp.setStatus(HttpServletResponse.SC_UNAUTHORIZED);
    // add this line
    req.getRequestDispatcher("/error401.jsp").include(req, resp);
    resp.flushBuffer();
    return null;

This page will be seen if the request gets cancelled after the
challenge is sent (NTLM type 2 message).  Also in
jcifs.http.NtlmHttpFilter you would add similar lines at about line
182 and line 196 (between the setStatus and flushBuffer).  Line 182 is
seen if authentication fails and the user is prompted again.  Line 196
is seen when the site is first visited and NTLM is started.
