Step 3: User Attribute Mapping.

  • User Attribute Mapping is mandatory for enabling users to successfully login into WordPress. We will be setting up user profile attributes for WordPress using below settings.
  • Finding user attributes

    • Go to Configure OAuth tab. Scroll down and click on Test Configuration.
    • WSO2 Single Sign-On (SSO) with WSO2 login credentials : test congifuration
    • 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.
    • WSO2 Single Sign-On (SSO) with WSO2 login credentials : test congifuration result
    • 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.
    • WSO2 Single Sign-On (SSO) with WSO2 login credentials : attribute/role mapping

Step 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.
  • wordpress oauth client plugin sso : attribute mapping
  • 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

  • wordpress oauth client plugin sso : test configuration - role mapping
  • 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.
  • wordpress oauth client plugin sso : test configuration - role mapping
  • 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.

Step 5: Login Settings / Sign In Settings.
