With Istio, you can enable authenticating end user. Currently, the end user credential supported by the Istio authentication policy is JWT.
|
||
The following is a guide for troubleshooting the end user JWT authentication.
|
||
|
||
1. Check your Istio authentication policy, `principalBinding` should be set as `USE_ORIGIN` to authenticate the end user.
|
||
|
||
1. If `jwksUri` isn’t set, make sure the JWT issuer is of url format and `url + /.well-known/openid-configuration` can be opened in browser; for example, if the JWT issuer is `https://accounts.google.com`, make sure `https://accounts.google.com/.well-known/openid-configuration` is a valid url and can be opened in a browser.

1. If the JWT token is placed in the Authorization header in http requests, make sure the JWT token is valid (not expired, etc). The fields in a JWT token can be decoded by using online JWT parsing tools, e.g., [jwt.io](https://jwt.io/).
|
||
|
||
1. Get the Istio proxy (i.e., Envoy) logs to verify the configuration which Pilot distributes is correct.
|
||
|
||
For example, if the authentication policy is enforced on the `httpbin` service in the namespace `foo`, use the command below to get logs from the Istio proxy, make sure `local_jwks` is set and the http response code is in the Istio proxy logs.

$ kubectl logs httpbin-68fbcdcfc7-hrnzm -c istio-proxy -n foo
