How can I fix it?
Thank you

I don’t think samba has the function implemented yet?

Thank you so much for feedback, if we find a temporary solution, let’s write it here, waiting samba feature

maybe it works with a local forwarding zone where the dns server of caaf.it and the ip of the dns server as caaf.it ip is configured on the UCS Server like:

Hi, I have been configured like this @externa1, but a client that have UCS as dns server doesn’t find a external domain host in caaf.it.
Caaf.it internal DNS server are reachable by clients
