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

  • The GRANT LOGON and REVOKE LOGON statements control which users have access from which client system connections.
  • A REVOKE LOGON statement inhibits only future logon attempts; it does not affect users who are currently logged on.
