Configuration with Negotiate/NTLM

[Markus Moeller]

I would like to test NTLM authentication but my (very) simple config does 
not work when the proxy asks for Negotiate.  I see an NTLM token going to 
the proxy but with DOMAIN NULL. I also don't see any traffic from the client 
nor proxy to AD.  I know my client can talk to AD ( at least the winbind 
check work).

Robot R3 = {
        kind = "R101";
        pop_model = { pop_distr = popUnif(); };
        recurrence = 55% / SimpleContent.cachable; // adjusted to get 55% 
DHR

        origins = S.addresses;      // where the origin servers are
        addresses = [ '192.168.1.127' ]; // where these robot agents will be 
created
        credentials = [ "WIN2003R2/mm at client1:pwd" ];
        dns_resolver = dr;
        pconn_use_lmt = exp(10*1024);
};

Do I have to configure more ?

Thank you
