[Samba] samba ldap with smbldap-tools cant join domain.

[Muhammad Reza]

Dear Lists

I have problem regarding configuring samba as domain controller with 
ldap authentication 
I use Samba-3.0.3-5 with Openldap-2.1.29 (running on Fedora Core 2).
I  follow guide from  www.idealx.org/prj/samba/smbldap-howto.en.html, 
with recent smbldap-tools for RedHat RPM,
Installation those packet was successfull,  so did  user management with 
smbldap-tools, i can login from another unix machine (ssh) with ldap 
account.
But when i try to join my windows machine to new domain controller with 
samba Administrator account and password , workstation always complain 
something about Logon Failure  "Unknown user name or Bad Password"
Log form my domain controller machine is (syslog 4) :
# tail -f log.smbd

Is there something i missed ? i assumed that samba now can connect to 
ldap service, and  i have an Adminstrator account at ldap DIT  and at 
secret.tdb with right password why still i can join my windows machine ?

Please help me, any suggest is very appriciate, and sorry for my poor 
english
