SAML Single Sign-On into Joomla using SimpleSAML | SimpleSAML SSO | Login using SimpleSAML
miniOrange Joomla SAML SP SSO plugin helps you to integrate your Joomla site to SimpleSAML using SAML 2.0 protocol. The miniOrange Joomla SAML SP Single Sign-on (SSO) plugin is simple to set up SimpleSAML SSO into Joomla and enable secure login into Joomla. As a result, users can access multiple Joomla applications with one login after authenticating with their SimpleSAML IDP credentials.
Our plugin is compatible with Joomla 3 as well as Joomla 4 with all the SAML 2.0 compliant Identity Providers. Here we will go through a step-by-step guide to configure SAML SSO login between the Joomla site and SimpleSAML by considering SimpleSAML as IDP (Identity Provider) & Joomla as SP (Service Provider).
What is SSO ?
Single sign-on (SSO) is an authentication method that enables users to access multiple applications with one-click login and one set of credentials. For example, after users log in to your Joomla site, they can automatically access all resources of the Joomla site. When you set up SSO, you configure one system to trust another to authenticate users, eliminating users' need to log in to each system separately. The system that authenticates users is called an Identity Provider. The system that trusts the Identity Provider for authentication is called the Service Provider.
Your SP then sends a SAML request to IDP when a user attempts to log in. Upon IDP authentication, it sends SAML assertions to the SP that provide information about the user. The assertion is received by SP, which then verifies it in accordance with the Identity Provider configuration and grants the user access to your Joomla website.
This detailed Handbook for the Joomla SAML SP Single Sign On plugin gives an in-depth explanation of the features of the plugin.

Steps to Integrate SimpleSAML Single Sign-On (SSO) with Joomla SAML SP
1. Download and setup Joomla SAML SP Plugin
Download the zip file for the miniOrange SAML SP plugin for Joomla from the link here.
Login into your Joomla site’s Administrator console.
From left toggle menu, click on System, then under Install section click on
Here click on Browse for file button to locate and install the plugin file downloaded earlier.
Once Installation of plugin is successful. Now click on Start Using miniOrange SAML SP plugin.
Then go to the Service Provider Metadata tab, scroll down and copy the
SP-EntityID and the ACS URL.
2. Configure SimpleSAML as IdP
Enabling the Identity Provider functionality
The first that must be done is to enable the identity provider functionality. This is done by editing
config/config.php (You can find this file in your simplesaml installation directory).
The option enable.saml20-idp controls whether SAML 2.0 IdP support is enabled. Enable
it by assigning true to them
Example: ‘enable.saml20-idp’ => true
Configuring the authentication module:
The exampleauth: UserPass authentication module is part of the exampleauth module. This module isn't enabled by default, so you will have to enable it. This is done by
creating a file named enable (file name) in modules/ exampleauth/.
On unix, this can be done by running (from the SimpleSAMLphp installation directory):
The next step is to create an authentication source with this module. An authentication source is an authentication module with a specific configuration. Each authentication source has a name, which is
used to refer to this specific configuration in the IdP configuration. Configuration for authentication
sources can be found in config/ authsources.php.
In this setup, this file should contain a single entry:
This configuration creates two users - student and employee, with the passwords studentpass and
employeepass. The username and password are stored in the array index (student: studentpass for the
student-user). The attributes for each user are configured in the array referenced by the index. So for
the student user, these are:
The attributes will be returned by the IdP when the user logs on.
Creating a self-signed certificate :-
The IdP needs a certificate to sign its SAML assertions with. Here is an example of an openssl-command which can
be used to generate a new private key key and the corresponding self-signed certificate. The private key and
certificate go into the directory defined in the certdir setting (defaults to cert/)
This key and certificate can be used to sign SAML messages:
openssl req -newkey rsa:3072 -new -x509 -days 3652 -nodes -out example.org.crt -keyout example.org.pem
The certificate above will be valid for 10 years.
You can generate it by using any online Tools and add them in cert directory.
The extension should be like:
example.org.crt //(Public Key)
example.org.pem //(Private Key)
SimpleSAMLphp will only work with RSA certificates. DSA certificates are not supported.
Configuring the IdP:- The SAML 2.0 IdP is configured by the metadata stored in metadata/saml20-idp-hosted.php. This is a minimal
$metadata['__DYNAMIC:1__'] = [
* The hostname for this IdP. This makes it possible to run multiple
* IdPs from the same configuration. '__DEFAULT__' means that this one
* should be used by default.
'host' => '__DEFAULT__',
* The private key and certificate to use when signing responses.
* These are stored in the cert-directory.
'privatekey' => 'example.org.pem',
'certificate' => 'example.org.crt',
* The authentication source which should be used to authenticate the
* user. This must match one of the entries in config/authsources.php.
'auth' => '' Example:- 'example-userpass', // You can find this in Step Number 3
Adding SPs to the IdP:-
The identity provider you are configuring needs to know about the service providers you are going to connect to
it. This is configured by metadata stored in metadata/saml20-sp-remote.php. This is a minimal example of a
metadata/saml20-sp-remote.php metadata file for a SimpleSAMLphp SP:
Replace example.com with your Joomla domain name.
$metadata['https://example.com/plugins/authentication/miniorangesaml/'] = [
'Assertion Consumer Service' => 'https://example.com/?morequest=acs',
'SingleLogoutService' => 'https://example.com/index.php?option=com_users&task=logout',
'NameIDFormat' => 'urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress',
'simplesaml.nameidattribute' => 'mail',
'simplesaml.attributes' => true,
'attributes' => array('mail', 'givenname', 'sn', 'memberOf'),
Note that the URI in the entityID and the URLs to the Assertion Consumer Service
and Single Logout Service endpoints change between different service providers. If you
have the metadata of the remote SP as an XML file, you can use the built-in XML to
SimpleSAMLphp metadata converter, which by default is available as
/admin/metadata-converter.php in your SimpleSAMLphp installation.
Here, you can also add user attributes you want to send from SimpleSAML to your Service Provider i.e
Go to SimpleSAMLphp homepage of installation.
The URL of an installation can be e.g.:
https://service.example.com/simplesaml/ where service.example.com has to be replaced by your
(Note: The installation page URL may differ depending on how SimpleSAML installation has been done)
Now go to Federation Tab and click on Show Metadata for SAML 2.0 IdP Metadata.
You can get the IdP metadata from here which will be required to configure the plugin.
Configure SimpleSAML Identity Provider with Joomla SAML Service Provider
In Joomla SAML plugin, go to Service Provider Setup Tab. There are three ways to configure
By Metadata URL :
Click on Upload IDP Metadata.
Enter Metadata URL (Copied from SimpleSAML) and click on Fetch Metadata.
By Uploading Metadata File:
Click on choose metadata file and click on Upload.
Manual Configuration :
Copy SAML Entity ID, SAML Single-Sign-On Endpoint URL and X.509 certificate from
Federation Metadata document and paste it in Idp Entity ID or Issuer, Single Sign-on Service
URL, X.509 Certificate fields respectively in the plugin.
Idp Entity ID or Issuer
SAML Entity ID in the Federation Metadata document
Single Sign-On Service URL
SAML Single-Sign-On Endpoint URL in the Federation Metadata document
X.509 Certificate in the Federation Metadata document
Click on Test Configuration.
Congratulaions we have successfully configured Joomla SAML Service Provider with SimpleSAML as Identity Provider.
