title: 407 Proxy Authentication Required
body: <p>I'm trying to use django-social-auth in my django app. While everything is ok on my mac, I got  407 Proxy Authentication Required when I'm trying to use same code on windows machine.</p>
  
  <pre><code> &lt;urlopen error Tunnel connection failed: 407 Proxy Authentication Required ( Forefront 
  
  TMG requires authorization to fulfill the request. Access to the Web Proxy filter is denied.  )&gt;
