Sign-on URL :	For "Web app / API" applications, provide the base URL of your app. eg, https://<domain-name> might be the URL for a web app running on your local machine. Users would use this URL to sign in to a web client 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.
