Teradata Vantageā„¢

When Vantage is connected to multiple client systems, the initial default is that logon permission is granted to all users from all client systems, and that all logons must include a password.

Logging on without a password requires the following things:
  • A GRANT LOGON statement that includes the WITH NULL PASSWORD option must be performed for the defined user name or must be the default for the host ID.
  • A security exit installed in the client system must acknowledge that the logon string for this user is valid without a password.
