The DefaultNegotiatingMechanism property is used to specify a default mechanism from among the mechanisms with the NegotiationSupported property set to yes. This property is used to determine the default mechanism when both the client and the server support mechanism negotiation.

For mechanisms that support the DefaultNegotiatingMechanism property, see Supporting Mechanisms for DefaultNegotiatingMechanism.

Any mechanism that has the mechanism property DefaultNegotiatingMechanism set to yes must also have the mechanism property NegotiationSupported set to yes; otherwise, the tdgssconfig executable reports an error.

If both client and server support negotiation, but no common negotiating mechanism exists between them, then the existing DefaultMechanism property is used to select a default mechanism.

Default Property Value

TDGSS sets the value of this property to no for all mechanisms for all platforms (Teradata Database, Unity servers, and clients).

Valid Settings

Setting Description

Mechanism Property Editable?
TDNEGO May Be Edited. Any mechanism that has this property set to yes, must also have NegotiationSupported set to yes.

Editing Guidelines

  • You can set the DefaultNegotiatingMechanism property on Teradata Database nodes, Unity server, and Teradata clients.
  • Any mechanism that has the mechanism property DefaultNegotiatingMechanism set to yes must also have the mechanism property NegotiationSupported set to yes, otherwise the tdgssconfig executable reports an error.
  • You can designate a different default mechanism and default negotiating mechanism for each client.
