I’m using generic oauthenticator to setup on-premise oauth2 service. This is the configuration I have done.

In the configmap file:
> auth:

          type: custom
          custom:
            className: oauthenticator.generic.GenericOAuthenticator
            config:
              login_service: "myservice"
              client_id: "client-id" 
              client_secret: "string"
              token_url: https://my-company.com/adfs/oauth2/token/
              userdata_url: https://my-company.com/adfs/userinfo
              userdata_method: GET
              userdata_params: {'state': 'state'}
              username_key: Name
             hub:
              extraEnv:
                OAUTH2_AUTHORIZE_URL: https://my-company.com/adfs/oauth2/authorize/
                OAUTH2_TOKEN_URL: https://my-company.com/adfs/oauth2/token/
                OAUTH_CALLBACK_URL: https://my-notebook.com/hub/oauth_callback

And this is my logs, It is redirecting to same url again and again.

What is the issue?
Thanks

I’m experiencing the same issue with helm chart version 0.9.0 (JupyterHub 1.1). Any help would be appreciated.

I’m curious if you figured out a solution? Thanks

Unfortunately, No. My applicaition is still stuck with dummy authenticator.

Did you try exporting these environment variables:
OAUTH2_TOKEN_URL # the same as token_url param
OAUTH2_AUTHORIZE_URL # oauth2 provider’s authorization endpoint
