[Samba] IDMAP LDAP problems

[Meli Marco]

Hi,
I running samba-3.0.13-1 on RH9
(openldap-2.0.27-8,krb5-1.2.7-10,nss_ldap-202-5) and configured as show
below, my intention is only to make IDMAP storage in LDAP using winbind.
I've looked on SAMBA3 by example book and relatives official guide on the
site.
First I have try to run samba and winbind retriving users and groups from
ADS and storing them in winbindd_idmap.tdb and winbindd_cache.tdb files and
it seems to work fine.
After I have introduce the LDAP backend and relative configuration as shown
below, but I have received the errors at the bottom of the message.
Why it doesn't work? I found only example that show domains with only one
prefix could I wrong the ldap configuration?
Thanks.
Marco.
