Integrating Drupal with Salesforce SSO via SAML and Dynamic User Sync

Single Sign-On (SSO) is a crucial part of modern web applications, enabling users to authenticate once and access multiple systems securely. If your organization uses Salesforce as an Identity Provider (IdP) and Drupal as a Service Provider (SP), you can establish a secure SSO connection using the SAML protocol.

In this blog, we’ll walk through how to integrate Drupal with Salesforce for SSO using the SAML Authentication module. We’ll also explore how to dynamically sync user data—like first name, last name, company, and roles—from Salesforce into Drupal during login.
