I want to join a UCS domain with an Ubuntu 22.04 server with SAMBA.
I had no luck following this guide: Setting up Samba as a Domain Member - SambaWiki
I can join a Windows Server 2016 Active Directory Domain, but when I try to join a UCS domain, it fails:
$ realm join MYDOMAIN.LOCAL
realm: Cannot join this realm
$ net ads join -U Administrator
Failed to join domain: failed to find DC for domain MYDOMAIN - The object was not found.
I can join the system as a client with the tool univention-domain-join-cli, but I need to join the SAMBA server as a domain member, so that external clients can authenticate to the shares provided by this server with the credentials of the UCS domain.
I can’t find any specific docs on this topic. Is this even possible?
