Purpose
Controls whether Teradata Database users can be authenticated outside (external) of the Teradata Database software authentication system.
Syntax
SET EXTAUTH { OFF | ON | ONLY }
- OFF
- Rejects external authentication logons; traditional logons are accepted.
- ON
- Accepts both external authentication and traditional logons. This is the default.
- ONLY
- Accepts external authentication logons only; traditional logons are rejected.
Usage Notes
External authentication may eliminate the need for your application to declare or store a password on your client system.
To configure how the network allows or disallows traditional and new external authentication logons, see Gateway Control (gtwcontrol).
The new setting is effective immediately.
To check the current setting, use GET EXTAUTH.
The SET EXTAUTH database command duplicates the functionality of the ExternalAuthentication setting in DBS Control. For more information on DBS Control, see DBS Control (dbscontrol).
For additional information on external authentication, see Teradata Vantage™ - Advanced SQL Engine Security Administration, B035-1100.
