Set up Single Sign-On (SSO) on your WordPress website via the PingFederate Identity Provider (IDP) with the WordPress OAuth & OpenID Connect Single Sign-On plugin. Implementing Ping SSO allows users to log into your websites and applications with a single set of credentials using the enterprise-level PingFederate OAuth provider.

The PingFederate OAuth WordPress plugin also provides advanced SSO features such as user profile attribute mapping, role mapping, and role-based access for user profiles. You can also protect your complete WordPress site behind SSO. Ping WordPress OAuth SSO plugin secure’s the user’s login process and improves user authentication authority.

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.
• Once you see all the values in Test Configuration, go to Attribute / Role Mapping tab, you will get the list of attributes in a Username dropdown.

4: Role Mapping [Premium]

• 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 SSO.
  Example: As per the given example, Users with role ‘teacher’ will be added as Administrator in WordPress and ‘student’ will be added as Subscriber.
