title: OpenID Connect, redirect without login form if not already logged in?
body: <p>In OpenID Connect, I would like my users to be automatically connected to my client if they are connected to the identity provider (given that they already authorized my client app).</p>
  
  <p>Here is the workflow I want :</p>
  
  <ul>
  <li>USER arrives on CLIENT homepage</li>
  <li>USER is redirected to IdP (Authorization request)
  
  <ul>
  <li>If he's logged in IdP, he's redirected to CLIENT and OIDC workflow begins, then he's logged in CLIENT</li>
  <li>If he's not logged in IdP or he did not authorize CLIENT to access his identity, the login form of IdP is NOT displayed to USER and he's redirected to CLIENT homepage, not logged in</li>
  </ul></li>
  </ul>
  
  <p>It would be like "Gateway" mode in CAS.
  I use Authorization Code Flow and I don't want to use Javascript with Implicit Flow to login through JS dynamically.</p>
  
  <p>Do you know if it is possible ? I can not find it in the spec.</p>
  
  <p>Thanks :)</p>
