Thanks, Marek. Will follow instructions there to check how things are
working when enabling a remote store with JDG.
I've also changed the authz cache mode to local, what I think makes more
sense than use a distributed cache as it stands today. We basically want to
cache things locally and invalidate entries accordingly to avoid stale
entries across nodes.
