 ### About the kube-api-auth Authentication Webhook
 
-The `kube-api-auth` microservice is deployed to provide the user authentication functionality for the [authorized cluster endpoint,](../../../../reference-guides/rancher-manager-architecture/communicating-with-downstream-user-clusters.md#4-authorized-cluster-endpoint). When you access the user cluster using `kubectl`, the cluster's Kubernetes API server authenticates you by using the `kube-api-auth` service as a webhook.

 During cluster provisioning, the file `/etc/kubernetes/kube-api-authn-webhook.yaml` is deployed and `kube-apiserver` is configured with `--authentication-token-webhook-config-file=/etc/kubernetes/kube-api-authn-webhook.yaml`. This configures the `kube-apiserver` to query `http://127.0.0.1:6440/v1/authenticate` to determine authentication for bearer tokens.
