samba - Jul 2007 - Using Unix/LDAP Log in Credentials for Security = User Share Authentication

All,

I'm new to Samba so this may be a very easy fix, but I've not been able 
to find it anywhere online or in the /Samba-3 By Example/ book.

I'm currently testing Samba 3.0.23c with an OpenLDAP v3 backend on 
CentOS 5.  I am able to get OpenLDAP installed and running for 
authentication and can get Samba installed and configured well enough to 
request and accept a LDAP user name/password when browsing to a share.  
However, I would like Samba to just use the user name/password that I've 
used as my login credentials for this step as well.  Currently when I 
browse to the share I am met with a dialog box that states: "You must 
log in to access guest@centos/test."  The dialog has a spot for user 
name, domain, and password.  The user name and domain are filled in with 
the correct information, but the password is not.  When I enter my log 
in password it lets me into the share correctly.  When I log into a 
Windows 2000 machine using the same credentials I am able to browse the 
share exactly as I would like to on the Linux box.

Also, both the Windows 2000 and Linux box were able to join the domain 
TEST and have accounts in the LDAP directory.

Below is a copy of my smb.conf file (copied and edited from /Samba-3 By 
Example)/:
