You can designate a default authentication mechanism other than TD2 on a client (for information, see the appropriate TTU reference or user guide for your specific client), the Unity server (if used), or on the database, using the DefaultMechanism property. See DefaultMechanism.

The system determines the default mechanism according to the following hierarchy:

  1. Client default
  2. Unity server (if used) default
  3. Teradata Database default
If the mechanism is disabled in the configuration file for the client, the Unity server (if used), or the database to which the user is connecting, the logon fails, regardless of how the mechanism was determined.
