Below, we provide a step-by-step guide on configuring SAML SSO login between your Joomla site and SiteMinder, with SiteMinder serving as the Identity Provider (IDP) and Joomla as the Service Provider (SP).

What is SSO ?

Single sign-on (SSO) is an authentication method that enables users to access multiple applications with one-click login and one set of credentials. For example, after users log in to your Joomla site, they can automatically access all resources of the Joomla site. The implementation of SSO involves configuring one system to trust another for user authentication, removing the need for users to log in separately to each system. The system that authenticates users is called an Identity Provider. The system that trusts the Identity Provider for authentication is called the Service Provider.
In this context, the system responsible for authenticating users is referred to as the Identity Provider (IDP), while the system relying on the Identity Provider for authentication is known as the Service Provider (SP). When a user initiates a login attempt, the Service Provider sends a SAML request to the Identity Provider. Upon successful IDP authentication, SAML assertions containing user information are transmitted back to the Service Provider. Subsequently, the Service Provider receives the assertion, verifies it based on the Identity Provider configuration, and grants the user access to your Joomla website.
