Instead of using the IP XML document method, you can create IP restrictions in a supported directory that serves the Teradata Vantage system(s).
If directory users log on through Unity, IP restrictions must be configured exactly the same for each database system managed by Unity. IP restrictions are not configured on Unity, which only passes the user IP address to Vantage.
You must use Teradata schema extensions to configure IP filter directory objects. Directories configured using only native directory schema cannot employ directory-based IP restrictions. See Using Native Directory Schema to Provision Directory Users.
