title: How does SPN with Kerberos works
body: <p>As I understand it,</p>
  
  <ul>
  <li>SPN is an authenticating tool for windows services.  </li>
  <li>Kerberos is a
  user authentication service</li>
  <li>SPNEGO-GSSAPI is the third party API to
  be able to use those services.  </li>
  <li>SSPI : is the Neutral layer to send
  request from SPNEGO to SPN service.</li>
  </ul>
  
  <p>Am I completely lost? </p>
  
  <p>Trying to figure out how it works but information, is either too precise or not enough. </p>
