Open Stack

We are in the process of integrating MAGNUM into our OpenStack distribution.
We are working with NEWTON version of MAGNUM.
We have the MAGNUM processes up and running and configured.

However we are seeing the following error (see stack trace below) on virtually all MAGNUM CLI calls.

The code where the stack trace is triggered:
def add_policy_attributes(target):
    """Adds extra information for policy enforcement to raw target object"""
    admin_context = context.make_admin_context()
    admin_osc = clients.OpenStackClients(admin_context)
    trustee_domain_id = admin_osc.keystone().trustee_domain_id
    target['trustee_domain_id'] = trustee_domain_id
    return target

( NOTE: that this code was introduced upstream as part of a fix for CVE-2016-7404:
 https://github.com/openstack/magnum/commit/2d4e617a529ea12ab5330f12631f44172a623a14 )

NotFound: The resource could not be found. (HTTP 404)


Any ideas on what our issue could be ?
Or next steps to investigate ?

thanks in advance,
Greg.
