[horizon][keystone] Adding different rules in the same protocol for federated logon

Hi all, I have yoga version openstack with the deployment tool of kolla-ansible. I am trying to combine different mapping rules such as allowing user to login to different domain. However, I am not able to do that in a single JSON file. When I try to include different rule in the same JSON file, only the first rule is being considered. Is there a way to allow multiple rule to redirect user to their account in a different domain. Best, James
