Help overriding Nova policies (Ussuri)

Hello,

I should miss something, and I need some help. I've updated some rules that I placed in the /etc/nova/policy.yaml file. I use all defaults for the olso policies (ie scope is not enabled).

When I generate the fulle policy with oslopolicy-policy-generator, the rules are applied in the generated output. If I test the policy with oslopolicy-checker under the user's token, the results matches the permissions, but Nova API continue to refuse the operation

Policy check for os_compute_api:os-flavor-manage:create failed with credentials

I'm using the openstack cli to make the request (openstack flavor create)

Thanks for your help
