"netbiosname" vs "netbios name". Order of parameter lookup through middleware is to (1) use libsmbconf, (2) look up in /etc/local/smb4.conf, then (3) get default through python loadparm context. Unfortunately the netbiosname->netbios name alias mapping doesn't appear to work through libsmbconf, so we fall back to the loadparm default, which is incorrect.
