Using python-keystoneclient on glance server:

>>> import keystoneclient.v2_0.client as k_client
>>> kc = 
k_client.Client(username='user',password='pass',tenant_name='tenant',auth_url="http://url:35357/v2.0";)
>>> kc.auth_token
u'07faf8d1e2b140aa9da3079949af7de6'
>>> import glance.client as g_client
>>> gc = g_client.Client(host='localhost', auth_tok=kc.auth_token)
>>> gc.get_images()
