these scripts do not work in synology active directory / DSM7

[TingYsf]

Thank you all very much for these scripts.

I am running AD in synology DSM7, same issue with DHCP not talking to DNS, and I tried this script but does not work.

I remember when I was using DSM6, I used a script and follow the instruction from following link, but now I am using DSM7, somehow I can not find synology's script dhcpd-script.sh under /usr/share/dhcpd/, this folder is no longer there.

Here was old link talking about a new script for DHCP and DNS at AD condition:

Wondering anybody have some good ideas?
