TDGSS uses the default mechanism when a user logon does not specify a mechanism. See Determining the Authentication Mechanism for a Logon for an explanation of how TDGSS determines the mechanism for a session.

Default Property Value

TDGSS initially sets the value of this property to yes for TD2, and to no for all other mechanisms, in the Teradata Vantage configuration files. TDGSS does not preset a default mechanism in the client configuration files.

Valid Settings

Setting Description
yes The mechanism is the default.
no The mechanism is not the default.

Editing Guidelines

  • You can set the DefaultMechanism property on Teradata Vantage nodes, Vantage clients, and on the Unity server.
  • You can set one only mechanism as the default on a Vantage system, but you can designate a different default mechanism for each client.
  • If you designate a new default mechanism, reset this property to no for the previous default mechanism.
  • If you do not designate a default mechanism, or if a user needs to use a non-default mechanism, the user must specify a mechanism.
