An new RPC set_iscsi_target_node_auth enables users to configure CHAP authentication for the target node dynamically. New setting is used for new iSCSI sessions. For existing iSCSI sessions, new setting is not used until user logout and login again. Try to use descriptive message in the RPC when error occurs.
