Set up Single Sign-On (SSO) on your WordPress website via Salesforce with the WordPress OAuth & OpenID Connect Single Sign-On plugin. Implementing Salesforce SSO allows users to log into your websites and applications with a single set of credentials using the Salesforce login credentials.

Salesforce acts as the OAuth Provider and WordPress acts as the OAuth Client. WordPress Salesforce Authentication provides smooth login between these two, removing the need to remember usernames and passwords.

The Salesforce OAuth WordPress plugin also provides advanced SSO features like user profile attribute mapping, role mapping, and granting site access based on Salesforce badges. You can also protect your complete WordPress site behind SSO. Salesforce WordPress OAuth SSO plugin secure’s the user’s login process and improves user authentication authority.

3. User Attribute Mapping

• User Attribute Mapping is mandatory for enabling users to successfully Single Sign-On (SSO) into WordPress using Salesforce SSO. We will be setting up user profile attributes for WordPress using the below settings

Finding user attributes

• Go to Configure OAuth tab. Scroll down and click on Test Configuration.

• You will see all the values returned by your OAuth Provider to WordPress in a table. If you don't see value for First Name, Last Name, Email or Username, make the required settings in your OAuth Provider to return this information.

• Click on “Test Configuration” and you will get the list of Attribute Names and Attribute Values that are sent by your OAuth provider.
• From the Test Configuration window, map the Attribute Names in the Attribute Mapping section of the plugin. Refer to the screenshot for more details.

• Enable Role Mapping: To enable Role Mapping, you need to map Group Name Attribute. Select the attribute name from the list of attributes which returns the roles from your provider application.
  Eg: Role


• Assign WordPress role to the Provider role: Based on your provider application, you can allocate the WordPress role to your provider roles. It can be a student, teacher, administrator or any other depending on your application. Add the provider roles under Group Attribute Value and assign the required WordPress role in front of it under WordPress Role.
  
  For example, in the below image. Teacher has been assigned the role of Administrator & Student is assigned the role of Subscriber.

• Once you save the mapping, the provider role will be assigned the WordPress administrator role after Salesforce SSO Login..
  Example: As per the given example, Users with role ‘teacher’ will be added as Administrator in WordPress and ‘student’ will be added as Subscriber.
