	NoServerRefErr = eris.New("no extauth server reference configured")
	ServerNotFound = func(usRef *core.ResourceRef) error {

var FilterStage = plugins.DuringStage(plugins.AuthNStage)

Note that although this configures the "envoy.filters.http.ext_authz" filter, we still want the ordering to be within the AuthNStage because we are using this filter for authentication purposes
