Grrr... This is probably a Samba issue - a known one? - but I can't seem to get AD authentications to hit multiple DCs. Everything goes to the one
This is indeed a Samba issue, and unfortunately a hard one to fix. ntlm_auth doesn't talk over the network - rather, it talks over a Unix socket to winbind. Winbind maintains a *single* open session to a DC, and sends all the domain RPCs down this pipe. Winbind discovers the DC from the AD subnet/site queries and builds an app-specific kerberos config that will show you this - see /var/lib/samba/smb_krb5/krb5.conf.<DOMNAME> If you want to force connections to separate domain controllers, you'll need separate smbd/winbindd instances running, with their own unix sockets and smb.conf setups. This will probably be hard, and fragile. My advice - don't, unless you really really need to.
