It seems to work - !"#ยค%&!
Combination of
-/etc/krb5.conf (though used realm for AD join)
- /etc/resolv.conf ( with the right dns sserver = tweak /etc/dhcpd/dhclient.conf +
/etc/NetworkManager.conf)
-/etc/hostname (fqdn)
-/etc/hosts (off with 127.0.1.1 fqdn shortname --> 127.0.0.1 fqdn shortname
localhost)
Without a beer ;), Thanks for help :)
