edX OAuth2 Provider Build Status codecov

OAuth2 provider for edX Platform.

edx_oauth2_provider is a Django application used for authentication and authorization in the edx-platform. The authentication mechanism is aligned with the OpenID Connect specification, supporting some of its basic features.

Usage

The OAuth2 clients must be registered to obtain their client_id and client_secret. The registration can be done using the /admin web interface by adding new entries to the OAuth2 Clients table.

Apart from the two basic OAuth2 client types (public and confidential), this provider has a notion of a trusted client. Trusted clients do not require user consent for accessing user resources, and will not show up the approval page during the sign-in process. To make a client trusted after it has been created, add it to the OAuth2-provider TrustedModel tables using the /admin web interface.

Open ID Connect

Currently, only the OpenID Connect profile scope is supported. Following the specification, OpenID Connect request should use the openid scope.

The id_token is signed (HMAC) using the client_secret with the SHA-256 algorithm.

The value of the setting OAUTH_OIDC_ISSUER MUST be set to the issuer URL. According to the OpenID connect to specification, it should use the https scheme, host and optionally the port number and path.

The id_token expiration, which defaults to 30 seconds, can be overriden by setting OAUTH_ID_TOKEN_EXPIRATION to a different value.

It is possible to customize the OpenID Connect scopes and claims, using the settings OAUTH_OIDC_ID_TOKEN_HANDLERS and OAUTH_OIDC_USERINFO_HANDLERS, which manage the claims associated with the id_token during authorization, and the results of the userinfo endpoint respectively. For more information see edx_oauth2_provider/oidc/handlers.py.

Adding new OpenID Connect scopes

Currently, because of a limitation of django-oauth2-provider, new scopes have to manually be added to the value of SCOPES in edx_oauth2_provider/constants.py. Future work could address this problem by making the configuration of new scopes occur dynamically or via registration.

Single Sign-Out

This library supports single sign-out/logout. In order to activate the functionality for your client, add a URL to the logout_uri field. Additionally, your provider's logout page should be updated to load the logout URL in a hidden iframe when the user logs out.

Testing

  • create a virtual environment
  • make requirements
  • make test # currently succeeds with warnings on python 2.7
  • make test-all # run tox tests, currently fails
