NTLMv2 authentication from linux

Question

Hello All,
I spent good amount of time on Internet tyring to figure this out, without any success. So i thought i would better ask.
We use corporate proxy to access internet. We have both linux & win box. We access internet from linux, via firefox, after authenticating with our win domain id/pass.
Recently our proxy authentication module was upgraded/configured to accept only NTLMv2. After this, firefox keeps on prompting for id/pass as if we provided in-correct credentials.
From whatever i read, NTLMv2 is an authentication protocol. A bit advanced from LM or NTLM protocols.
So i am not sure whether firefox doesn't support NTLMv2 or should i install some package helping firefox to speak NTLMv2 or i am missing something.
Cheers,
Uday.

It's an old post but the basic problem is that the code shown doesn't implement NTLMv2 authentication at all. It just implements basic password authentication.
Does anyone know whether Sun's Linux implementation of JDK 1.6 supports NTLMv2 authentication protocol?@OP: you should have read the link you provided! It clearly says that NTLM authentication via java.net.Authenticator only works on Windows platforms, and it works by not calling your installed Authenticator. If yours gets called, it is not working or not available.
There are other problems:
public static PrintStream setupPrintStream( String fileName ) throws FileNotFoundException
PrintStream out  = null;
File        file = new File( fileName );
file.delete();
FileOutputStream stream  = new FileOutputStream(fileName, true);
out     = new PrintStream( stream );
return out;
}All that could be reduced to new PrintStream(new FileOutputStream(fileName), false). You don't even need the method.
