Authorization through Unity | Teradata Vantage - About Authentication of Users Logging On through Unity - Advanced SQL Engine - Teradata Database

In an environment that contains multiple Teradata Vantage systems, you can use Unity to process and selectively route user queries to the systems based on defined rules. The query processing by Unity is unknown to the user, who is authenticated and authorized in the standard way, according to the security mechanism (default or specified) in effect at the time of logon.

To use Kerberos or LDAP authentication, you must complete several setup tasks on the Unity server and on all connected Vantage systems. For information about Unity, see Teradata® Unity™ Installation, Configuration, and Upgrade Guide for Customers, B035-2523 and Teradata® Unity™ User Guide, B035-2520.
