title: Get All Domain users in Google App Engine
body: <p>I want to get the list of all the users for the domain on a GAE app (using python). When I hit this URL <a href="https://apps-apis.google.com/a/feeds/domain/user/2.0" rel="nofollow">https://apps-apis.google.com/a/feeds/domain/user/2.0</a> . I get an authorization error. How can I authenticate for this GET hit.</p>
