I agree with Vish here. A common set of group names would be a good first step and allow us to federate authn without the upfront complexity of trying to also federate authz. Come to think of it, there's no reason that role A would need to have similar privileges in zones X and Y. More likely than not, they would have different privileges, and therefore a federated authz service wouldn't really make sense.
