SAML Single Sign-On into Joomla using ADFS

miniOrange Joomla SAML SP SSO plugin helps you to integrate your Joomla site to ADFS using SAML 2.0 protocol. Our user-friendly plugin simplifies the process of setting up Single Sign-on (SSO) with ADFS (Active Directory Federation Services) in Joomla, ensuring a secure login experience. This enables users to access various Joomla sites effortlessly using their ADFS IDP credentials.

Our plugin is designed to be compatible with Joomla 3, 4 as well as 5 and works seamlessly with all SAML 2.0 compliant Identity Providers. For a detailed overview of the comprehensive features offered by the Joomla SAML SP plugin, please visit our page here. Below, we provide a step-by-step guide on configuring SAML SSO login between your Joomla site and ADFS, with ADFS serving as the Identity Provider (IDP) and Joomla as the Service Provider (SP).

Email: Name of the email attribute from IdP (Keep NameID by default)
Name: Name of the name attribute from IdP

More FAQs ➔

There are a couple of reasons why this can happen:

1. Caching is enabled on the website.
When auto-redirect is enabled, the user is redirected to the IDP login page and after logging in back to the main site but as caching is enabled it redirects to the IDP login page hence a loop.

2. HTTP/HTTPS discrepancy:
This happens when HTTPS is not enforced on the site but is configured on the IDP side with an HTTPS URL. This can be solved by enforcing HTTPS on the site by defining a redirect rule in the .htaccess file or at the Apache level.

3. Cookie adulteration:
The cookie created by the plugin after logging in the user is altered by another plugin which causes the user to not log in to the Joomla site but the session is created on IDP.

In Joomla SAML plugin, when an extension is not enabled after installing the plugin, after clicking on ‘Test Configuration’ it takes you to your own site instead of redirecting you to IDP. To resolve it, you need to enable all the extensions of the plugin after installing it.

Please follow the below steps to resolve this issue:

1. In the Joomla admin interface, go to Extensions -> Manage -> Manage.
2. Search for ‘miniorange’.
3. Enable all the extensions of the plugins.

Here are some frequent errors that can occur:

INVALID_ISSUER: This means that you have NOT entered the correct Issuer or Entity ID value provided by your Identity Provider. You’ll see in the error message what was the expected value (that you have configured) and what actually found in the SAML Response.
INVALID_AUDIENCE: This means that you have NOT configured Audience URL in your Identity Provider correctly. It must be set to https://base-url-of-your-joomla-site/plugins/authentication/miniorangesaml/ in your Identity Provider.
INVALID_DESTINATION: This means that you have NOT configured Destination URL in your Identity Provider correctly. It must be set to https://base-url-of-your-joomla-site/plugins/authentication/miniorangesaml/saml2/acs.php in your Identity Provider.
INVALID_SIGNATURE: This means that the certificate you provided did not match the certificate found in the SAML Response. Make sure you provide the same certificate that you downloaded from your IdP. If you have your IdP’s Metadata XML file then make sure you provide certificate enclosed in X509 Certificate tag which has an attribute use=’ signing’.
INVALID_CERTIFICATE: This means that the certificate you provided is not in a proper format. Make sure you have copied the entire certificate provided by your IdP. If copied from IdP’s Metadata XML file, make sure that you copied the entire value.

This is possible only when a certificate coming in SAML Response does not match with the certificate configured in the plugin. Copy the certificate value shown in the Test Configuration window and paste it in X.509 Certificate field in the Service Provider tab in the plugin.

1. Navigate to Admin tools >> Control Panel then click on the .htaccess maker option.
2. Then disable the option ‘Protect against common file injection attacks’.

Click on the Test Configuration and review the configuration result window. Ensure that the Attribute Mapping has been done correctly and verify that the X.509 Certificate Value is accurate.
