DreamFactory OAuth support.

1. Log in to the DreamFactory admin interface.
2. Navigate to Security > Authentication > Add Service.
3. Choose the desired provider from the Service Type dropdown.
4. Enter the required details:
   • Namespace: Must end with _oauth (e.g., github_oauth).
   • Label: Example: GitHub Sign In. This label will be displayed on DreamFactory's login page as the text on the provider's sign-in button.
   • Client ID: Obtained from the provider's application settings.
   • Client Secret: Obtained from the provider's application settings.
   • Redirect URL: This must match the provider's application settings and the DreamFactory configuration. It should point to the /sso endpoint.
     • Example: If your namespace is github_oauth, the redirect URL should be:

       https://your-dreamfactory-instance.com/api/v2/github_oauth/sso
       

5. Save the configuration.
6. Log out, reload the page, and the new OAuth login option for the configured provider should be visible.
