SAML allows information to be exchanged between Service Providers and Identity Providers; SAML is the integration of Service Providers and Identity Providers. When a user attempts to log in, your Service provider delivers SAML assertions to Identity Provider, which contain information about the user. The assertion is received by Identity Provider, which validates it against your Service Provider settings before allowing the user access to your org.

Steps to configure SimpleSAML SAML Single Sign-On (SSO) Login into Magento SAML SP

1. Setup SimpleSAML as IdP (Identity Provider)

Follow the steps below to configure SimpleSAML as IdP for Magento

 Configure SimpleSAML as IdP

• In the Magento SAML SP SSO plugin, navigate to Service Provider Metadata tab. In this tab you will find the SP metadata such as SP Entity ID and ACS (AssertionConsumerService) URL which are required to configure SimpleSAML as the Identity Provider.

• In config/config.php, make sure that 'enable.saml20-idp' is true. Example: ‘enable.saml20-idp’ => true
• In metadata/saml20-idp-hosted.php, configure SimpleSAML as Identity Provider like this:

  $metadata['__DYNAMIC:1__'] = [ 
  
              'host' => '__DEFAULT__',
  
              /* X.509 key and certificate. Relative to the cert directory.*/ 
  
              'privatekey' => '<YOUR_PRIVATE_KEY_FILE_NAME>',    //eg. RSA_Private_Key.pem 
  
              'certificate' => '<YOUR_PUBLIC_KEY_FILE_NAME>',    //eg. RSA_Public_Key.cer 
  
              /* Authentication source to use. Configured in 'config/authsources.php'. */ 
  
              'auth' => '<YOUR_AUTH_SOURCE_NAME>'
  
          ];

• In metadata/saml20-sp-remote.php, register your Servider Provider like this:
  /* Replace example.com with your Magento domain name. */
  

          $metadata['https://example.com/miniorange-saml-20-single-sign-on/'] = [ 
  
              'AssertionConsumerService' => 'https://example.com/', 
  
              'SingleLogoutService'      => 'https://example.com/', 
  
              'NameIDFormat' => 'urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress', 
  
              'SimpleSAML.nameidattribute' => 'mail', 
  
              'SimpleSAML.attributes'      => true,  
   
              'attributes' => array('mail', 'givenname', 'sn', 'memberOf'),
  
          ];

• Here, you can also add user attributes you want to send from SimpleSAML to your Service Provider i.e Magento.
• 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 SimpleSAMLphp path. (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.

You have successfully configured SimpleSAML as SAML IdP (Identity Provider) for achieving SimpleSAML Single Sign-On (SSO) Login, ensuring secure SimpleSAML Login into Magento Site.

2. Configure Magento as SP (Service Provider)

• 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	x.509 Certificate in the Federation Metadata document

• Click on Save button to save all your settings.

• To check if your Magento as SP is configured correctly, click the Test Configuration button.

3: Attribute Mapping (Optional). *This is Premium feature.

• Attributes are user details that are stored in your Identity Provider.
• Attribute Mapping helps you to get user attributes from your Identity Provider (IdP) and map them to Magento user attributes like firstname, lastname etc.
• While auto registering the users in your Magento site these attributes will automatically get mapped to your Magento user details.
• Only NameID can be mapped to Magento's Email and Username characteristics with the free plugin. Multiple user attributes from the IdP, on the other hand, can be mapped to Magento attributes in the premium version of the plugin. You can map custom attributes that you've added to your IdP in addition to the default attributes.
• When a user performs SSO, the NameID value sent by the IdP will get mapped to the email and the username of the Magento user.


Username:	Name of the username attribute from IdP (Keep NameID by default)
Email:	Name of the email attribute from IdP (Keep NameID by default)
Group/Role:	Name of the Role attribute from Identity Provider (IdP)

• You can check the Test Configuration Results under Service Provider Setup tab to get a better idea of which values to map here.

4: Role Mapping (Optional). *This is Premium feature.

• You can specify a default role in the free plugin that will be allocated to all non-admin users when they conduct SSO.
• Go to Attribute/Role mapping tab and navigate to Role Mapping section.
• Select the Default Role and click on the Save button.
