[Samba] Trouble with PDC setup using Samba 3.0.23 and OpenLDAP

Hi everyone,

I am trying to setup a PDC using Samba and OpenLDAP.  For some reason, I've 
used both the examples provided in the Official Howto and also the 
smbldap-tools howto developed by IDEALX.  I am able to get the directory up 
and running.  I am able to get the following working:

1.  LDAP Directory server and successful Queries through Samba
2.  Add user and machine accounts.
3.  Login using the user account to access shares

However, after adding my machine to the domain and rebooting my Windows 2000 
Professional workstation, I am UNABLE to login to the domain using the same 
User account that I was able to use to access shares on the Samba server.  
Here is what I am getting in the logs for both OpenLDAP and Samba

I'm getting the error bdb_equality_candidates: (uniqueMember) index_param 
failed (18) when its trying to obtain the attribute gidNumber from the LDAP 
logs.  In the samba logs, Its getting a Rejecting auth request from client 
DELL machine account DELL$

Also when I do a net rpc info, I don't see any users or groups added...

net rpc info
Domain Name: POON
Domain SID: S-1-5-21-2419779023-3102034070-987042703
Sequence number: 1154241602
Num users: 0
Num domain groups: 0
Num local groups: 0

I don't know where to start...Please let me know if you have had a similar 
experience and found a solution.  I appreciate your help very much!

-Jonathan P.

I am wondering what is in /etc/ldap.conf, specifically the lines:

nss_base_passwd  
nss_base_shadow  
nss_base_group  

Are the computer accounts stored in the same ou as People?

This is likely where your problems with machine accounts and Groups is.

I would probably remove the comments from csc policy and profile acls
lines here but that isn't the issue at the moment.

The logs you have quoted above don't show what happened when the DELL$
tried to authenticate nor what happened when you tried getent group (as
far as I can tell) so I am not going to speculate further.
