title: Keycloak - Missing data in the userinfo response
body: <p>When I hit <code>/auth/realms/{realm}/protocol/openid-connect/userinfo</code> I get very little details about the user. </p>
  
  <pre><code>{
      "sub": "ed291f7a-a799-4d8b-a776-e634d727668c",
      "email_verified": true,
      "preferred_username": "admin"
  }
  </code></pre>
  
  <p>More info (such as role lists) is inside the access token that I'm actually sending to this endpoint. I could just decode the access token instead of hitting this endpoint, is this expected/normal behavior or am I doing something wrong?</p>
