  I tried with keeping the keystone V2.0 confgurations but that is giving authentication problems.
  admin_username=ironic
  admin_password=IRONIC_PASSWORD
  admin_url=http://IDENTITY_IP:35357/v2.0
  admin_tenant_name=service
  api_endpoint=http://IRONIC_NODE:6385/v1

  when i try the above values in ironic as per officeial document I am getting below error
   oslo_service.service DiscoveryFailure: Could not determine a suitable URL for the plugin

  Keystone endpoints are with v3
