Your OpenStack services must now point their OpenStack Identity configuration to the highly available, virtual cluster IP address — rather than a OpenStack Identity server’s physical IP address as you normally would.
For example with OpenStack Compute, if your OpenStack Identity service IP address is
192.168.42.103 as in the configuration explained here, you would use
the following line in your API configuration file
(api-paste.ini):
auth_host = 192.168.42.103
You also need to create the OpenStack Identity Endpoint with this IP.
NOTE : If you are using both private and public IP addresses, you should create two Virtual IP addresses and define your endpoint like this:
keystone endpoint-create --region $KEYSTONE_REGION --service-id $service-id --publicurl 'http://PUBLIC_VIP:5000/v2.0' --adminurl 'http://192.168.42.103:35357/v2.0' --internalurl 'http://192.168.42.103:5000/v2.0'
If you are using the Horizon Dashboard, you should edit the local_settings.py file:
OPENSTACK_HOST = 192.168.42.103
