SAML Single Sign-On (SSO) into Tableau using Joomla IDP Plugin

Single Sign-On in Tableau using Joomla IDP allows users to log in to Tableau using Joomla by configuring Tableau as a Service Provider (SP) and Joomla as a SAML Identity Provider (IDP). This guide will take you through a step-by-step process to configure SSO between the two platforms.

What is Tableau?
Tableau is a powerful business intelligence tool used for data visualization in the form of charts, graphs, and more, to gain business insights for better company development. It is an interactive tool that helps business managers and team leaders make quicker and more appropriate decisions. Non-technical staff can also create customized dashboards for their work using Tableau's drag-and-drop interface.
