From Backstage feedback:
3.2. Implementing Identity Data Stores When you first set up a realm, the new real inherits the data store from the parent realm. For example, in an installation where the Top Level Realm has the embedded OpenDJ server as the identity data store, any new realm created would have the embedded OpenDJ server as the identity data store by default. typo: "the new real inherits", "real" should be realm.
