Directory Notification

Active Directory provides a control for clients to register to receive changes notifications. Note the following constraints when configuring your search:

scope Must be one-level or object-level
filter Must be ‘(objectClass=*)’
attributes list of attributes to be returned when a change occurs. Does not specify attributes which will generate notifications.

A notification client is provided to encapsulate the asychronous search and expose a blocking queue.
