> With this series applied, enabling role-based ACLs is a matter of:

> - Configuring southbound ovsdb-server and ovn-controller to use SSL,
> configuring an ovn-controller "role" for SSL connections via e.g.:
> ovn-sbctl set-connection role=ovn-controller pssl:6642
> - Using unique certificates for each ovn-controller with a unique
> CN for each chassis, generated e.g. via:
> ovs-pki -B 1024 req+sign chassis1 switch
> ovs-pki -B 1024 req+sign chassis2 switch
> ovs-pki -B 1024 req+sign chassis3 switch
> - Starting the southbound ovsdb-server with the "--rbac" command-line
> option:
> --rbac=db:OVN_Southbound,RBAC_Role

Here are the local modifications I've been using to exercise ovn with
rbac enabled in the sandbox environment:
