JCIFS + Tomcat 5 + NTLM Challenge Question

All,

I've recently implemented the jcifs library with a servlet on Tomcat v5.0.28 and
it works very well.

However I have one question.

When someone get's the NTLM challenge screen and they hit cancel they are
directed to a blank screen vs. getting the 401 Unautorized. How can I resolve
this, is it something I'm not configuring properly?

I hope this is the right board to post this topic to...

Thanks in advance!

Matt
