Hi,
It seems, that I see regression with claim port functionality in my OVN
installation between v20.06.2 and latest branch-20.06 (78174ea) on cluster with
enabled rbac.
On v20.06.2 ovn-controller successfully claims port:
# ovn-controller --version
ovn-controller 20.06.2

I’ve configured rbac consulting with this instruction:

Can anybody point me what could go wrong?
Am I missing something?
