Hello, this is by design. We often may want masters and replicas to have a different set of rules. If you want the same rules, you should propagate the same ACL rules to all the instances. Maybe in the future we may add a feature that allows replicas to have a copy of the ACLs from the master, and in that case the replicas will not accept any ACL command that modifies the rules.
