Drupal (SP-initiated) Integration Guide


Use this guide to enable Multi-Factor Authentication and Single Sign-on (SSO) access via SAML to Drupal.


These instructions apply to Linux instances of Drupal only


1. On the Drupal host server, SimpleSAMLphp must be installed and configured – review the readme for information

2. Create a New Realm for the Drupal integration with the SecureAuth IdP Web Admin

3. Configure the following tabs on the Web Admin before configuring the Post Authentication tab:

  • Overview – the description of the realm and SMTP connections must be defined

  • Data – an enterprise directory must be integrated with SecureAuth IdP

  • Workflow – the way in which users will access this application must be defined

  • Multi-Factor Methods – the Multi-Factor Authentication methods that will be used to access this page (if any) must be defined

SecureAuth IdP Configuration Steps



1. In the Profile Fields section, map the directory field that contains the user's Drupal ID to the SecureAuth IdP Property

For example, use the Email 1 Property if this Property is not currently used


Click Save once the configuration is complete and before leaving the Data page to avoid losing changes

Post Authentication

Post Authentication


2. In the Post Authentication section, select SAML 2.0 (SP Initiated) Assertion from the Authenticate User Redirect dropdown

The uneditable Authorized/SAML20SPInit.aspx URL populates the Redirect To field – this content will append to the domain name and realm number on the address bar


A customized post authentication page can be uploaded, but is not required

User ID Mapping


3. Select the SecureAuth IdP Property corresponding to the directory Field that contains the Drupal username

For this example, select Email 1 from the User ID Mapping dropdown

4. Select urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified from the Name ID Format dropdown (default)

5. Select False from the Encode to Base64 dropdown

SAML Assertion / WS Federation


6. Set the SAML Consumer URL to https://drupalserver/simplesaml/module.php/saml/sp/saml2-acs.php/default-sp

This is the setting made in Drupal Configuration Step 5 below

7. Set the WSFed/SAML Issuer to https://secureauthidp

This setting should match the Entity ID value from Drupal Configuration Step 6a below

8. Set the SAML Audience to https://drupalserver/simplesaml/module.php/saml/sp/metadata.php/default-sp

This setting should match the Entity ID value from Drupal Configuration Step 3 below

9. Set SP Start URL to https://drupalserver/saml_login

10. Leave the Signing Cert Serial Number as the default value, unless a third-party certificate is used for the SAML assertion

If using a third-party certificate, click Select Certificate and choose the appropriate certificate

11. OPTIONAL: Provide the Domain URL

12. Click certificate.wse3.cer to download the SecureAuth IdP certificate

SAML Attributes / WS Federation


13. Under Attribute 1, set the Name to eduPersonPrincipalName

14. Select Authenticated User ID from the Value dropdown

15. Under Attribute 2, set the Name to mail

16. Select Email 1 from the Value dropdown


Click Save once the configuration is complete and before leaving the Post Authentication page to avoid losing changes
