i find out the issue. the issue is with doc https://docs.openstack.org/cinder/queens/install/cinder-controller-install-ubuntu.html still pointing to auth_url = http://magellan:35357 it should be
auth_url = http://magellan:5000. after changing that its working fine.

Hi, i think this doc is queen base which is not updated to auth_url = http://controller:5000 and yes after doing the same we can resolve the issue .

The latest release have updated reference.[1]
