Setup OAuth Client for Internal Services (Django Oauth Toolkit version)

Step-by-step guide

1. Create a new worker user with staff access in LMS (usually <service>-worker)

Also see this devstack script for creating the service worker.

2. Create 2 different OAuth applications at https://<lms>/admin/oauth2_provider/application/
   

1.        Client_id: <autogenerated>
          User: select <service> worker that you created with app-permissions
          Redirect Uris: <blank>
          Client type: Confidential
          Authorization grant type: Client credentials
          Client secret: <autogenerated> (not sure if autogenerated is secure enough for prod)
          Name: <service>-backend-service
   
   
2.        Client_id: <autogenerated>
          User: select <service> worker that you created with app-permissions
          Redirect Uris: https://<service_url>/complete/edx-oauth2/
          Client type: Confidential
          Authorization grant type: Authorization code
          Client secret: <autogenerated> (not sure if autogenerated is secure enough for prod)
          Name: <service>-sso
          Skip Authorization: checked

Also see this devstack script for creating the oauth applications.

1. Add a user_id application access scope for the new <service>-sso app here:
   https://courses-internal.edx.org/admin/oauth_dispatch/applicationaccess
   1. Note: This is handled by the management command in the devstack script and is only needed if doing this manually.
2. Set the following keys in the configuration settings of your service

SOCIAL_AUTH_EDX_OAUTH2_KEY = '<service-sso-key>'
SOCIAL_AUTH_EDX_OAUTH2_SECRET = '<service-sso-secret>'
SOCIAL_AUTH_EDX_OAUTH2_ISSUER = 'https://<lms_url>'
SOCIAL_AUTH_EDX_OAUTH2_URL_ROOT = 'https://<lms>'
SOCIAL_AUTH_EDX_OAUTH2_LOGOUT_URL = 'https:<lms>/logout'
BACKEND_SERVICE_EDX_OAUTH2_KEY = '<service-backend-service-key>'
BACKEND_SERVICE_EDX_OAUTH2_SECRET = '<service-backend-service-secret>'
