Hi all,

here's the solution to my own question:

Permissions to /etc/samba/smb.conf were 640,
however 644 (or read access for bind/named) is required
for dlz to work.

Once found the fix is trivial, however the samba_dlz
error message didn't really point to the real cause
of this trouble :-(

Something like "/etc/samba/smb.conf: permission denied"
would be very nice.
