Oauth2/OpenID authentication for cubicweb

Summary

Oauth2/OpenID connect authentication client for cubicweb.

All configuration is done in all-in-one.conf. Defaults values should work fine with Keycloak, for other provider refer to the documentation of the content of the JWT token.

• oauth2-enabled should be set to yes once it is configured

• oauth2-client-id and oauth2-client-secret should be set (given by the provider).

• For OpenID connect providers oauth2-server-url can be set. For keycloak it is https://<server>/auth/realms/<realm>. The configuration is then obtained from the metadata url /.well-known/openid-configuration

• If you want to avoid a request to the metadata url, or if your provider doesn’t implement OpenID, you should to configure oauth2-authorization-url, oauth2-token-url and oauth2-jwk-path.

• oauth2-token-login is used to map a field of the JWT token with CubicWeb login.

• On the provider side, the callback url should be configured to https://<cubicweb>/oauth2/callback

At this point you should be able to log in an existing user through the login page using the “Log in with Oauth2” button.

If you want to automatically register new users, you must set oauth2-register-user to yes and configure oauth2-default-group, oauth2-token-firstname, oauth2-token-surname and oauth2-token-email.

If your instance only accepts users from the Oauth2 provider, you can set oauth2-auto-login which skip the login page and start oauth2 authentication directly.

If your instance require authenticated users from Oauth2 provider only, you can set oauth2-force-login to yes, this will redirect all unauthenticated requests to oauth2 login.

How to test this with keycloak

Using standard flow and confidential (client_id/client_secret) access.

test_full_login() might be a good entry point to understand the authentication flow.

Here is how to test this with keycloak:

1. Create a new client using url http://:8080

2. Set Access Type to “confidential” with standard flow enabled

3. Get client_id & client_secret from the “Credentials” tab

4. Enable the oauth2 cube to your project

5. In all-in-one.conf set these parameters:

   oauth2-enabled=yes oauth2-server-url=https://keycloak/auth/realms/master oauth2-client-id=<client_id> oauth2-client-secret=<client_secret>

6. Start your instance, go to login page and click on “Log in with Oauth2”
