[Samba] Samba with LDAP -> Can't include Windows Client

Hi,

at first sorry for my horrible englisch.
My name is Benjamin Nagel and I had setup a lot of Samba Server, but 
untill now without LDAP as backend.

My data:
Suse 9.2
Samba 3.0.9-2.3-SUSE
OpenLDAP: slapd 2.2.15

I had setup Samba and OpenLDAP like the IDEALX documentation. I can 
create a linux user with the smbldap-useradd script and I can login with 
this user.
But when I want to include a Windows XP client I get a error.

Samba create the machine account.

This is a snapshot of the client logfile:

Dear Benjamin,

we have Samba running on SuSE 9.3. What we found out is that for the 
machine accounts you MUST NOT use ou=computers BUT ou=people, that means 
the same ou as you use for normal accounts. This phenomenon is also 
somewhere described in the Samba by example tutorial.

At least in our environment this works.

Hope this helps,

best

Joachim
