[Samba] Separate ISC-DHCP server updating BIND DNS

[Brandon Nishan]

I am attempting to set up a separate ISC-DHCP server to administer IP addresses for a new subnet and dynamically update the main BIND9 DNS server on DC1. I'm using the guide linked below but it appears to be for installing the DHCP server directly on the domain controller. Is there any documentation available for updating BIND9 from a completely separate machine with ISC-DHCP installed? It doesn't seem like copying over the DHCPuser keytab works (dns_tkey_negotiategss: TKEY is unacceptable).

Thanks,
