If you created the driver in a driver set where you already activated the Identity Manager engine and service drivers, the driver inherits the activation. If you created the driver in a driver set that has not been activated, you must activate the driver within 90 days. Otherwise, the driver stops working.
For information on activation, refer to Activating Identity Manager in NetIQ Identity Manager Setup Guide for Linux or Activating Identity Manager in NetIQ Identity Manager Setup Guide for Windows..
