If you manage Teradata Vantage users in a directory, you must provision the users, that is, create and configure the directory objects that define user privileges in the database.
You can provision users using only the native directory schema, or you can add Teradata schema extensions, which provide additional capabilities.
You cannot restrict user access by IP address unless you use Teradata schema extensions. See Restricting Logons by IP Address.
For information on directory provisioning using the native directory schema, see Using Native Directory Schema to Provision Directory Users.
