Web Gateway access with Kerberos

Hello,

Looking for some additional help with setting up and configuring the Web Gateway with Kerberos.

Have read through the documentation (at the link below) and it's a good start but seems there are some details missing, or I'm not clear on. 

Questions: 

• Is there a external enterprise Kerberos server required, or is this set up contained within the local server?
•  Is there a step-by-step instructions on what to do and configure to successfully complete this?

The environment is RHEL8, with 2023.1 HealthShare.

Any help much appreciated, thank you.
