I wonder why these are masked. On a stock Debian install, if you are
installing a domain controller (not a member), then you should:

    systemctl stop smbd nmbd winbind
    systemctl disable smbd nmbd winbind
    systemctl mask smbd nmbd winbind
    systemctl unmask samba-ad-dc
    systemctl enable samba-ad-dc

Did the OP follow directions for a DC?

I'm seeing names like "FSDC" which sounds like OP is confused.
