title: Invalid signature while validating Azure ad access token, but id token works
body: <p>I am getting invalid signature while using jwt.io to validate my azure ad access token. My id token, however, validates just fine!</p>
  
  <p>I have seen and tried the solutions suggested in<br>
  <a href="https://stackoverflow.com/questions/45038651/invalid-signature-while-validating-azure-ad-access-token">Invalid signature while validating Azure ad access token</a><br>
  and<br>

  but neither works for my access token.</p>
  
  <p>The access and Id token is generated via Adal.js:</p>
  
  <pre><code>    var endpoints = {
          "https://graph.windows.net": "https://graph.windows.net"
      };
      var configOptions = {
          tenant: "&lt;ad&gt;.onmicrosoft.com", // Optional by default, it sends common
          clientId: "&lt;app ID from azure portal&gt;",
          postLogoutRedirectUri: window.location.origin,
          endpoints: endpoints,
      }
      window.authContext = new AuthenticationContext(configOptions);
  </code></pre>
  
  <p>Why can I validate my ID token, but not my access token?</p>
