body: <p>I am trying to list all the keystone projects present on my setup. The snippet i am using displays only few of them.</p>
  
  <p><strong>CODE-1:</strong></p>
  
  <pre><code>from keystoneclient.auth.identity import v3
  from keystoneclient import session
  from keystoneclient.v3 import client as ksclient3
  auth_url = "http://192.16.66.10:5000/v3"
  token = '0112efcb75e9411b965b423edb321827'
  auth = v3.Token(auth_url=auth_url, token=token, unscoped=True)
  sess = session.Session(auth=auth)
  ks = ksclient3.Client(session=sess);
  project_list = [t.name for t in ks.projects.list(user=sess.get_user_id())]
  print project_list
