Although it has this in the main script: echo -e "\n"`basename ${0}` "uses samba-tool to update DNS records in Samba 4's DNS" echo "server when using INTERNAL DNS or BIND9 DLZ plugin." I could never get my version of this script to update the internal dns server. Rowland

The Samba script was written to be used with debian and here dhcpd runs as root. It would seem that another way needs to be found to update the kerberos ticket, perhaps in root's crontab ? Rowland
