title: WWW-Authenticate uses NTLM and not Kerberos
body: <p>I'm running a NodeJS server on a Windows Server 2008.</p>
  
  <p>The server doesn't do much but I set the header for 401, WWW-Authenticate Negotiation which I know can go either with his default Kerberos authentication or if it's not available then with NTLM.</p>
  
  <p>I downloaded fiddler and discovered that when I try to reach the server it tries to authenticate with NTLM(prompt me for username and password) rather than Kerberos, even though the computer is in the same domain as the server and when I do run the command "klist" it does show me that he has tokens which means that he already authenticated with Kerberos(doesn't it?).</p>
  
  <p>My question is how can I make it authenticate with Kerberos rather than NTLM - why does he go to NTLM in the first place?</p>
  
  <p>Any ideas?</p>
