Building Custom AutoLogin Module for Liferay Integration with Azure AD B2C

Azure AD B2C provides a robust, cloud-based identity management solution that offers secure authentication, multi-factor authentication support, and seamless integration with enterprise systems. When combined with Liferay's flexible portal capabilities, you get a powerful platform that can handle complex authentication scenarios while maintaining a great user experience. The Solution: Custom AutoLogin Module The approach involves creating a custom AutoLogin component that intercepts the authentication flow, validates tokens from Azure B2C, and automatically logs users into Liferay. Let's break down the implementation. Step 1: Create the AutoLogin Class First, we need to create a class that extends BaseAutoLogin. This class will handle the authentication logic: public class WebsiteAutoLogin extends BaseAutoLogin { @Reference private UserLocalService userLocalService ; private RestTemplate restTemplate ; @Activate public void activateComponent () { restTemplate = new RestTemplate (); } }
