Which process acts as a proxy between Tableau Server and SAML Identity Providers?

The SAML Service acts as a proxy between Tableau Server and SAML Identity Providers. This is crucial in environments where organizations utilize Single Sign-On (SSO) capabilities for user authentication and authorization. When Tableau Server needs to authenticate a user, it communicates with the SAML Identity Provider (IdP) to verify the user's identity. The SAML Service facilitates this communication by managing the SAML assertions and handling the authentication workflow, ensuring that users can log in seamlessly without having to enter credentials multiple times.

In this role, the SAML Service streamlines the process of authentication by encapsulating the necessary protocols and security measures required to exchange information with the IdP securely. This ensures a smooth and efficient user experience while maintaining robust security standards for user access to Tableau Server.

Other options do not fulfill this proxy function. The Repository is responsible for storing configuration data and metadata used by Tableau Server. The Administration/TSM Agent is involved in the management and administration of server processes but does not handle authentication. Tableau Prep Conductor is a tool for managing and scheduling Tableau Prep workflows, and is unrelated to the SAML authentication process.
