I think you may have had /etc/hostname with the fqdn, whereas it
_should_ only have the hostname.

IOW:
You have to have
hostname -s
return _just_ the hostname _without_ the domain.
And:
hostname -f 
return the fqdn

I understand that you now have the domain join and sssd auth from the
keytab without either the DNS update nor the something not found errors?

Dare I mention that it is really nice with sssd v1.10 and above as it
gives us dynamic dns updates on the fly for Linux clients, just like
windows. Pero no digas nada a nadie lol.

Salu2,
