SAML Single Sign-On (SSO) into Joomla Using SharePoint as IDP
miniOrange Joomla SAML SP SSO plugin helps you to integrate your Joomla site to SharePoint using SAML 2.0 protocol. Our user-friendly plugin simplifies the process of setting up Single Sign-on (SSO) with SharePoint in Joomla, ensuring a secure login experience. This enables users to access various Joomla sites effortlessly using their SharePoint IDP credentials.
Our plugin is designed to be compatible with Joomla 3, 4 as well as 5 and works seamlessly with all SAML 2.0 compliant Identity Providers. For a detailed overview of the comprehensive features offered by the Joomla SAML SP plugin, please visit our page here. Below, we provide a step-by-step guide on configuring SAML SSO login between your Joomla site and SharePoint, with SharePoint 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. Users can automatically access all resources of the Joomla site once they are login using SSO.
- 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.
- When a user initiates a login attempt, the Service Provider sends a SAML request to the Identity Provider. Upon successful IDP authentication, a SAML response containing user information is transmitted back to the Service Provider. Subsequently, the Service Provider verifies SAML response based on the Identity Provider configuration, and grants the user access to your Joomla website.
Pre-requisites: Download And Installation
Steps to Integrate SharePoint Single Sign-On (SSO) with Joomla SAML SP
