Does an AD Query cache results?

As an FYI regarding updating the lifetime (probably with clearing the cache as well), I tested it in our development environment and it seemed to work fine. When I made the change in production, I didn't "apply access policy" (since it marks all associated policies as needing to be applied) for our Exchange stuff, but even still, all our Exchange and OWA users could no longer log in. Only after applying the access policy were they able to get back in.

Just thought I'd mention this. Apparently the change does something on the back end to disrupt access (in certain situations, I guess) if the policy is not immediately applied.
