SAML Single Sign-On (SSO) into Drupal using Auth0 as IdP

Overview

The Drupal SAML integration using the miniOrange SAML SP module establishes seamless SSO between Auth0 and the Drupal site. The users will be able to log in to the Drupal site using their Auth0 credentials. This document will walk you through the steps to configure Single Sign-On - SSO between Drupal as a Service Provider (SP) and Auth0 as an Identity Provider (IdP). The module is compatible with Drupal 7, Drupal 8, Drupal 9, and Drupal 10, and Drupal 11.

Setup Auth0 as SAML Identity Provider

• Log into your Auth0 admin console.
• Navigate to the Applications and select Applications.

• Click on Create Application button.

• On the Create application, enter the Name of application (in this case, DrupalSAML) and select Regular Web Applications. Click on the Create button.

• Navigate to the Addons tab and enable the SAML2 WEB APP toggle.

• On the Addon: SAML2 Web App window, navigate to the Settings tab and provide the information into the corresponding text field from the Service Provider Metadata tab of the module.

  Auth0 Field	Service Provider Information (Drupal)
  Application Callback URL	SP ACS URL
  audience	SP Entity ID/Issuer
  recipient	SP ACS URL

• Scroll down and click on Enable button, then click Save button to save SAML SP information.

On the same window, navigate to the Usage tab, find the Identity Provider Metadata and click the Download link to get the IdP metadata file. Keep the IdP metdata file handy. This information is required to configure Drupal as SAML Service Provider (SP).

Configure Drupal as SAML Service Provider:

• Navigate to the Service Provider Setup tab of the Drupal site and click on Upload IDP Metadata.

• In the Upload Metadata File field and upload the IdP metadata file that you downloaded from Auth0. Then, click on Upload File button to proceed.

• Click on the Test link to test the connection between Drupal and Auth0.

• On a Test Configuration popup, if you don't have an active session in the Auth0 on the same browser, you will be asked to sign in to Auth0. After successfully login into Auth0, you will be provided with a list of attributes that are received from the Auth0. Click on Done

Congratulations! you have successfully configure Auth0 as SAML Identity Provider (IdP) and Drupal as SAML Service Provider.

How does SAML SSO login work?

• Open a new browser/private window and navigate to the Drupal site login page.
• Click the Login using Identity Provider (Auth0) link.
• You will be redirected to the Auth0 login page. Enter the Auth0 credentials. After successful authentication, the user will be redirected back to the Drupal site.
