I feel a bit silly. So I've gone ahead and run the following commands
as I've gathered they needed adapted from the windows commands given
in the link posted before;
samba-tool spn add HTTP/gw.domain.com at DOMAIN.COM fwuser
The last piece there is the service user I've created for the firewall.
Then I ran:
samba-tool domain exportkeytab gw.keytab --principal=fwuser

When I attempted to import the keytab into the firewall however, I was
presented with the following error:
"service principal name "fwuser" is not allowed (not start with HTTP)"

This is where I was getting hung up, and I presume something declared
in the PaloAlto docs indicates how the file/spn is formatted. But I'm
not sure how that needs to translate to the samba commands (if
possible).

Thanks,
Ralph
