On Ubuntu it wouldn't, but this should:
sudo smbd -b | grep LIBDIR

Now this is interesting, in your 'samba -b | grep LIBDIR' above, the
location is /usr/local/samba, yet it then changes to /var/lib/samba.
The Samba wiki is written from the point of view of a self compiled
Samba, where the default location for everything is /usr/local/samba,
the default location for most of Samba using the Ubuntu packages
is /var/lib/samba, so what are you using, a self compiled Samba, or
the Ubuntu packages ?

Hmm, looks like Ubuntu packages.
Check if these three packages are installed: libpam-winbind libpam-krb5

Why have you got a line that should only be in a DC smb.conf ?

You should only have the 'winbind enum' lines for testing purposes.

Replace the above line with:
idmap config DOMAIN : unix_nss_info = yes

> idmap config DOMAIN : range = 50000-1000000
Does the 'Domain Users' group have a gidNumber attribute containing a
number inside the range above ?
Do your users have a uidNumber attribute containing a unique number
inside the same range ?
