I changed the 'idmap config' block on my computer to this:

    idmap config *:backend = tdb
    idmap config *:range = 2000-9999
    idmap config SAMDOM : backend = rid
    idmap config SAMDOM : range = 10000-999999

Restarted smbd, nmbd and winbind, then:

root at devstation:~# net cache flush
root at devstation:~# getent passwd samdom\\rowland
rowland:*:11107:10513:Rowland Penny:/home/rowland:/bin/bash

root at devstation:~# getent group "samdom\\domain admins"
domain admins:x:10512:administrator,swanadmin,rowland

As you can see, it works ;-)

If it isn't working for you, you must have something misconfigured or
something missing, What do you have in /etc/hostname, /etc/hosts
and /etc/resolv.conf ?
What packages did you install with the Samba packages ? (note: not the
base OS packages, the packages installed when you installed Samba)

I’ve done exactly as you (view /etc/samba/smb.conf below) but nothing changed!

I think I understand it now ;-)

The debian Samba package used to install winbind as a dependency, it
doesn't now, try running this (as root):

apt-get install winbind libnss-winbind libpam-winbind

The last two packages are the 'glue' between winbind and nsswitch
