Automatic certificate download with ClearPass

To improve the ease of deployment, Aruba switch allows automatic downloading of the root CA certificate of ClearPass servers. As a part of the ZTP process, if the configuration of the switch is provided with an additional keyword ClearPass in RADIUS configuration, the switch will contact ClearPass and download the root CA certificates. This simplifies use cases such as Downloadable User Roles as well as Device Fingerprinting with ClearPass.
