Setting up Kerberos on a High Availability Environment

Hi,
My team have currently setup an AD Connection with two connector instances for High Availability. We have a requirement to enable Kerberos. We have followed the auth0 document (https://auth0.com/docs/connector/kerberos#configuration). However Kerberos works perfectly only on one machine. We face random failures on the second machine where the login page gets displayed frequently instead of using Kerberos. There is no pattern to this and we are stuck. Please provide your insights on this. Kindly let us know the correct sequence of steps to be followed to implement kerberos Authentication on a HA environment. Provide any detailed document if you have.

We do not see any logs getting generated for Kerberos even after adding “DEBUG=kerberos-server” environment variable. Kindly let us know if any custom logs can be added to monitor Kerberos transactions.
Please help. Thanks in advance.
