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.

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

Did you try exporting these environment variables:  
OAUTH2\_TOKEN\_URL # the same as token\_url param  
OAUTH2\_AUTHORIZE\_URL # oauth2 provider’s authorization endpoint
