Basic auth authorization on istio ingress



We are using Istio in version 1.0.3, k8s cluster in version 1.12.3

Is it possible to establish authorization using basic auth on istio ingress level?
We have tried to provide proper ServiceRoleBinding and ServiceRole resources but in case of invalid request we are expecting 401 response, not 403 like in mentioned case (some http client based on first 401 return code send again request with basic auth header).

Do you have any suggestions?

Thanks for help in advance :slight_smile:
