Configuring SSO Using WSO2 Identity Server

Single sign-on is a feature that allows users to access more than one application with the same credentials. This article shows how we can configure SSO using the WSO2 Identity Server. There is a cab company called Pickup that has two web applications called pickup-manager and pickup-dispatch, which use WSO2 IS as their identity provider. After SSO configuration is done for both applications, the users need to provide credentials only for one application, and they can automatically log in to the other application. This article shows SSO implementation using two ways — SAML 2.0 and OpenID Connect/OAuth 2.0.

Prerequisites

1. WSO2 Identity Server (IS) 5.11.0.
2. Apache Tomcat 8.5.
3. Download saml2-web-app-pickup-dispatch.com.war, saml2-web-app-pickup-manager.com.war and pickup-dispatch.war, pickup-manager.war from this repository.

Implementation Steps (SAML 2.0)

1. Start the WSO2 IS server by running wso2server.bat or wso2server.sh present under <WSO2IS_HOME>/bin.
