Teradata Vantage provides the following methods to control external authentication:
For a host group:- The DBSControl utility controls external authentication for all users.
- The Gateway Control utility controls external authentication for users that log on through a particular gateway or host group.
- If either the DBSControl or Gateway Control utility is set to disable external authentication, external authentication is disabled. Users entering through that gateway cannot be externally authenticated.
- If either the DBSControl or Gateway Control utility is set to allow only external authentication, users entering through that gateway can only be authenticated externally. Setting either of these controls to allow only external authentication also prevents mainframe connections unless the TDP is also set up for external authentication.
You can also use the Database Window interface, or comparable command-line interfaces to the Console Subsystem (CNS), such as cnsterm and cnstool, to manage external authentication. The SET EXTAUTH command toggles the same internal control switch used by the DBSControl utility. You can use the GET EXTAUTH command to check whether or not external authentication is enabled.
