What process involves managing authentication on the same network as Teradata?

External Authentication involves managing user identities and their access rights outside of the Teradata database itself, while still applying these controls over the same network where Teradata operates. This method leverages existing authentication systems, such as LDAP or Active Directory, to validate users before granting access to Teradata resources.

This is beneficial for organizations that want to maintain centralized user management and leverage existing security infrastructures. By using external authentication, enterprises can simplify user administration and enhance security by not duplicating user credential storage within Teradata, ensuring that user management aligns with organizational policies and can be managed across multiple systems.

Other approaches, although they may address aspects of user access and security, do not focus on the integration of external systems for user identity verification in a manner that enhances network-wide security and control.
