Subject Re: List/Empty queue on a Cluster
Date Mon, 20 Mar 2017 19:53:12 GMT
I observed that only the Cluster Coordinator Node (which also happens to be
the Primary Node) needed to be on the Access Policy, not all Nodes.

More to the point, why do the Node(s) themselves need to be on the policy?
When not Clustered, the machine does not need to be on the policy. Perhaps
this is necessary in a Cluster because one Node propagates the request the
remaining Nodes.. so it is the Node making the request, not the individual

Looking for clarification.
