With new RBAC enabled: Tempest test failing on NetworkNotFound

[Ghanshyam Mann]

I was testing the tempest with new RBAC enabled which mean in neutron.conf enable the below options:

[oslo_policy]
enforce_scope = True
enforce_new_defaults = True

https://zuul.opendev.org/t/openstack/build/930366c016de49c4b7c26f69b371411a/log/controller/logs/etc/neutron/neutron_conf.txt#1928

In that case tempest tests are failing with NetworkNotFound. For example verfy first test failure in

From the q-svc log (screen-q-svc.txt): below error is coming from ovn side:

[None req-1e9ba6eb-84f1-4091-bf3a-862d6e6cb127 admin admin] Mechanism driver 'ovn' failed in create_network_postcommit: neutron_lib.exceptions.NetworkNotFound: Network 75ccd449-9526-4dc2-96c3-4f76ac9dcbe2 could not be found.
