When Teradata Database 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.
