  <h1>OpenID consumer demo</h1>
  <p>
   The login form below uses a hidden iframe to process the form
   (assuming the user has javascript enabled; if they don't, it falls back
   gracefully). If your identity provider implements checkid_immediate
   properly (which several don't appear to), and has enough information to
   authorise you without requiring your input, the entire login process
   should happen without any noticable change except for the status message.
  </p><p>
   If your identity provider requires interaction with you, the form
   will be submitted as usual and you'll leave this page (but, as usual, will
   return when your IdP is done with you). If your identity provider is
   <em>broken</em>, you won't see anything happening after the initial page
   load and redirect. This is because the identity provider is trying to
   interact with you (via a hidden iframe) when it has been explicitly told
   not to. This is the identity provider's fault (it's violating the OpenID
   specifications), not Poidsy's. If you were implementing this on a live site,
   you'd probably add a timer to detect if it wasn't working and do a normal
   login.
  </p>
  <p>
   Note: if you are using Firefox and have the 'Disallow third party cookies'
   preference enabled, Firefox won't send cookies to your provider when it's
   loaded in the iframe. This almost certainly will mean that your provider
   can't validate your identity immediately, and thus you'll be redirected.
   Other browsers (such as IE and Safari) allow these cookies to be sent even
   if they disallow setting of third-party cookies.
