OpenStack Mitaka Issue starting the Nova API service on the controller "ERROR nova MissingRequiredOptions: Auth plugin requires parameters which were not given: auth_url"
This issue was faced at the time of starting the nova-api service on the controller node on the OpenStack Setup. The reason was a misconfigured nova api.
As usual for nova related service best place to look out are the logs in /var/log/nova/* on the controller machine.
The below messages appear in the /var/log/nova/nova-api log
==> nova-api.log <==

2016-07-06 06:32:18.257 27284 ERROR nova
The fix:
This comes if you have not define or improperly defined the auth_url in the /etc/nova/nova.conf
in my case this has been in /etc/nova/nova.conf as
auth_url = http://controller1.example.com:35357
Also is worth noting another entry in the file as auth_uri in the /etc/nova/nova.conf
as
auth_uri = http://controller1.example.com:5000
