You can optionally use a RADIUS (Remote Authentication Dial-in User Service) server to centrally manage passwords for iSCSI authentication. Using RADIUS simplifies password management, increases security, and offloads authentication processing from Data ONTAP storage systems only.
You can configure either one-way authentication (the target authenticates the initiator), or mutual authentication (the initiator also authenticates the target).
For information about configuring this RADIUS server, see the Windows online Help.
For information about configuring the storage system to use RADIUS, see the SAN Administration Guide for your version of Data ONTAP.
