TTU 16.10 and later no longer supports an independent TeraGSS package for client machines. Instead, the client interfaces embed TeraGSS functionality and the previous method of configuring TeraGSS is not possible. If you need to configure TeraGSS, you must install the Teradata Generic Security Service Administrative package (teragssAdmin) included in TTU.
Although teragssAdmin is provided for configuring TeraGSS, Teradata recommends not configuring TeraGSS on the clients.
