title: C# AuthenticationTypes?
body: <p>I came across the following line in a piece of code that uses Microsoft Active Directory:</p>
  
  <pre><code>const AuthenticationTypes ADS_EDMSERVER_BIND = (AuthenticationTypes)0x8000;
  </code></pre>
  
  <p>What exactly does this line mean ? Particularly, what is the <code>0x8000</code> mean ?</p>
