If cacheResults() returns true the caching mechanism in ExternalStore is used. I can't remember if Oliver added timeouts to that cache (I think he did recently), but if not objects are expired when the cache fills or when the object changes. With the roundtrip times involved in loading information from LDAP the preemptive caching strategy was a necessity. I'd recommend avoiding it if possible since it adds a bit of complexity.
