MAC Book unable to operate with Kerberos authentication. If working, provide configuration details.

I'm not really sure if this is related to your firewall or not. Does Kerberos auth work on your MacBook at all or is the firewall failing to identify the user logged into the MacBook authenticated by Kerberos? There are very strict steps that you need to take to make Kerberos auth work on a MacBook.

can you elaborate on what exactly is not working ?
is your Mac having issues reaching the Kerberos server through the firewall, or are you authenticationg to the firewall with your mac and is the firewall set to use kerberos to authenticate the session (captive portal, global protect , ....)
as @BPry mentions the steps to configure Kerberos on the Mac itself are very strict, but on the firewall you should simply allow the necessary applications to allow kerberos through, you should see these in the traffic log (kerberos and possibly some rpc/netbios)
