Diagnosis
By default, API calls require authentication. For the sake of lab testing, it is possible to disable this authentication.
root@openstack:~# cat /etc/contrail/contrail-api.conf | grep auth
auth = keystone
Solution
Replace "keystone" with "none" and restart.
Here is an example Python session that no longer requires authentication:
root@openstack:~# python
