Set proxy server authentication for clusters using Kerberos
In a cluster using Kerberos, applications check host credentials to verify that the host they are connecting to is the same one that is actually processing the request, to prevent man-in-the-middle attacks. To clarify that the load-balancing proxy server is legitimate, you need to perform these extra Kerberos setup steps.
This procedure assumes you are starting with a Kerberos-enabled cluster.
