Traefik and rbac on microk8s

Traefik Traefik v2
1

I got 2 test cluster with microk8s and traefik installed via helm. One worked, the other didn't... until I realized the cluster that didn't work had rbac enabed ("microk8s.enable rbac").

I installed as follows:

helm repo add traefik https://containous.github.io/traefik-helm-chart
helm repo update
kubectl create ns traefik
helm install traefik traefik/traefik --values traefik-values.yaml -n traefik

What do I need to do to make it work with rbac?
Here is the content of traefik-values.yaml are:
