title: Heroku ssl:endpoint with GlobalSign ExtendedSSL
body: <p>I have signed up for GlobalSign ExtendedSSL.</p>
  
  <p>I just can't figure out how to add this to <code>ssl:endpoint</code> addon.</p>
  
  <p>When I signed up for ExtendedSSL i had to generate CSR certificate, which has the following files:</p>
  
  <ul>
  <li>private-key.key</li>
  <li>www.domain.com_csr.pem</li>
  </ul>
  
  <p>Once the sign was complete, GlobalSign gave me the following:</p>
  
  <ul>
  <li>SSL Certificate</li>
  <li>ExtendedSSL Intermediate Certificate</li>
  <li>Extended Validation Cross Certificate</li>
  </ul>
  
  <p>I have combined SSL Certificate, ExtendedSSL Intermediate Certificate and Extended Validation Cross Certificate server.crt.
  And I have copied private-key.key to server.key</p>
  
  <p>When i try to add it to the add, i get:</p>
  
  <pre><code>$ heroku certs:add server.crt server.key --app myapp
  Resolving trust chain... failed
  ! No valid, non-passphrase-protected keys given.
  </code></pre>
  
  <p>Does anyone know what I did wrong?</p>
