System Information OS : UBUNTU 16.04 openstack version : stable/stein

when trying to register a kubernetes vim using the openstack cli error returned is 404 Not Found (On analysing the packet data with tcp dump) openstack is wrongly hitting v3 identity server at the kubernetes authentication host (ie trying to hit /v3 in the kubernetes api, which is non-existing which in-turn results in the 404), is this a bug, or is there any configuration change or workaround to get this kubernetes vim registered?
