If that is how it should be working, then either I am doing something very wrong or there are a few bugs.
With the following settings:
nethserver ad host: ip 192.168.0.5
nethserver ad host: DNS set to 22.214.171.124 in Networking settings.
samba container IP: 192.168.0.6
Random DHCP server in network supplying 192.168.0.5 as DNS, clients can not ping eachother by hostname. The entries that end up in the samba container DNS are not propagated to the nethserver ad host. Due to this being so, I added this specific part to my guide, and just repeated it
Let me know where I fubar or what I dont get here.
When I use the 192.168.0.6 for DNS for clients, entries on the DNS page of the nethserver host are not functional for clients.
