I joined some ubuntu clients to UCS domain controller. Is it possible to change the nameserver in /etc/resolv.conf on the clients to another DNS server? That DNS server runs dnsmasq, and forwards all requests to either UCS master or an external DNS server.
I did a grep in /etc on the linux clients, and the only place where the IP of ucs master appears is /etc/resolv.conf. So I think it should work, as long as dnsmasq replies to the queries with the same result as the UCS master would. But I am interested in learning from other fellows and UCS staff.
