[Samba] once again reverse DNS - bind_dlz

[Jan JMPBL]

Thank you for your response.
I changed everything according to your instructions.
It looks like the problem is gone. I'll check in tomorrow's logs.

Another strange log appeared:
root: DHCP-DNS delete failed: 255: 255: 0: 0
dhcpd [17258]: execute: /usr/local/bin/dhcp-dyndns.sh exit status 256

It appeared after shutting down one computer that was not joined to a
domain.

Thanks,

Jan
