Either on the commandline with "samba-tool user create <newuser>" or
over the RSAT from a windows-machine.

Yes, otherwise I would not seen any user with "getent passwd"

It a Debian 7 with the new SerNet Package 4.13

here is the smb.conf from a DC:

- -------
        workgroup = NTD
        realm = egf.ntd
        netbios name = SVL-V-AD1
        server role = active directory domain controller
        idmap_ldb:use rfc2307 = yes
        dns forwarder =
        wins support = yes
        local master = yes
        load printers = no
        printing = bsd
        printcap name = /dev/null
        disable spoolss = yes
