In an environment that contains multiple Teradata Database 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.

Unity supports logons using of the following authentication mechanisms:

  • TD2
  • KRB5
  • SPNEGO
  • LDAP

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