[jcifs] Windows login username required at server end

[Yannick Lavanant]

Well, there is a class called jcifs.http.NTLMHttpFilter that you should 
be able to extend. You could then override some methods to stop the 
authentication. Then of course, change you web.xml to use the new filter 
class.

I'm not sure how doable that is, but your best bet is to read the filter 
class and see what you can do with it.

There are a lot of message exchange going on between the client and the 
server during the authentication. So if you manage to intercept that 
process at the right time, you might be able to do what you want.

Yannick
