I'm trying to test an AD driver policy for when an attribute changes but for some reason, no event seems to be happening. I modify the attribute in LDAP and watch the trace for the AD driver but see nothing happening on the subscriber channel. I stopped the AD driver, tried modifying the attribute in LDAP again and looked at the unprocessed transaction for the AD driver but there aren't any. I'm not quite sure why. Am I misunderstanding something? I don't have much experience with the AD driver.
