The clusterRoleBindings check can output false alarm even if `cluster-reader` role is assigned to fluentd service account and logging works as expected. The check used to query for `cluster-readers` CRB, but the common command `oc adm policy add-cluster-role-to-user cluster-reader system:serviceaccount:logging:aggregated-logging-fluentd` no longer appers to add the SA into `cluster-readers` group but instead creates cluster-reader-1 CRB. ``` $ oc get clusterrolebindings cluster-readers -o yaml ... roleRef: name: cluster-reader ... userNames: null $ oc get clusterrolebindings NAME ROLE USERS GROUPS SERVICE ACCOUNTS SUBJECTS ... cluster-reader /cluster-reader management-infra/management-admin cluster-reader-0 /cluster-reader default/router cluster-reader-1 /cluster-reader logging/aggregated-logging-fluentd cluster-readers /cluster-reader system:cluster-readers ... ``` This fix queries all clusterrolebindings, iterates over those, that have role `cluster-reader` and then validates there is a `cluster-reader` entry for `system:serviceaccount:logging:aggregated-logging-fluentd`
