title: IdSrv4 - Access Token Validator EndPoint
body: <p>I set up an Identity Server 4 server. In identity server 3 we have the endpoint available, so we can do the following:</p>
  
  <pre><code>POST /connect/accesstokenvalidation
  
  token=&lt;token&gt;
  </code></pre>
  
  <p>I supposed it is the same on identity server 4, but I get a <code>404 NOT FOUND</code>. Then I entered to: <code>http://my-endpoint.com/.well-known/openid-configuration</code> and the endpoint is not present.</p>
  
  <p>Should I set up something to make it available on identity server 4?</p>
