I'm on ubuntu 18.04 which is part of an active directory domain using sssd.
How can get my ubuntu to register its hostnmae to the dns server.
I saw How to get Ubuntu Host to Register Hostname With DNS Server which seems to not apply to 18.04 has it's not using dhclient ?
I did not find anything in netplan to do this.
I found a way to do it with systemd-networkd: https://unix.stackexchange.com/questions/450032/systemd-networkd-dhcp-hostname-option but it's not doing it and I don't any error message anywhere regarding the fact that networkd is trying and failing.
Any idea ?
