-to do so , what you need to is follows: 
-1. create a application on you IdP(purple line)
-2. change your [oauth2 proxy issuer](https://github.com/kubeflow/manifests/blob/35539f162ea7fafc8c5035d8df0d8d8cf5a9d327/common/oauth2-proxy/base/oauth2-proxy-config.yaml#L10) to your IdP. 
-3. under istio-system namespace, there is a requestauthentication , you also need change it issuer to your own IdP.( or you can just directly write a new one)
-4. finally , now you can directly use issue a token from your IdP. and take thit token to access you kubeflow platform.
