  • 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

  • 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.
