[jcifs] NTLM authentication performance

[Eric]

Attached is a simple web app which uses the JSP stuff.  You will have to 
edit the jcifs.http.domainController init-param to point to an SMB box; 
also, make sure the jCIFS jar is available (this was tested under 0.7.6, 
but should work at least a few revisions back).

You should then be able to go to http://somebox/test/index.jsp, and 
click around.  index.jsp itself doesn't use the class, but the target of 
the POST (test.jsp) does.

Note that use of the extends attribute for JSP pages is generally 
considered poor practice; many servlet containers make assumptions about 
the page implementation which don't hold when you provide a different 
implementation.  This could be the issue you're seeing, although without 
access to a WebSphere container I couldn't tell for sure.  The 
<jsp:forward> might also be causing flukes (I haven't tested that).

As I'm looking at this more closely, I think I see the issue -- there is 
a bug in NtlmServlet.  You're using jcifs.http.domainController = 
"ngsmobile"; is that a domain?  The reason I'm asking is that I just 
noticed NtlmServlet does

UniAddress.getByName(value);

instead of

UniAddress.getByName(value, true);

The difference is that the second will allow for the possibility that 
"value" is a domain/workgroup (rather than a hostname).  This needs to 
be fixed; in the meantime, see if it works by changing the 
jcifs.http.domainController to an IP address.
