Teradata Database automatically grants permission for all users defined in the database to logon from all connected client systems. But administrators can, for example:
- Modify current or default logon privileges for specific users.
- Give individual users permission to log on to the database only from specific mainframe or workstation interfaces.
- Set the maximum number of times a user can submit an unsuccessful logon string.
- Enable authentication of the user by an external application, such as Kerberos or LDAP.
- Restrict access to the database based on the IP address of the machine from which a user logs on.
