samba - Oct 2005 - Logging into linux machine using AD account?

Greetings. I have just started scratching the surface of using Samba to 
create a SSO environment for my network. I have been playing a bit with 
both SuSE 9.3 and CentOS 4.1 to authenticate to an AD PDM (W2K).

I've made it the farthest with the CentOS server.  I have joined it to 
the domain and been able to verify AD users and groups using wbinfo 
[-u|-g] and getent [passwd|group]. I have even been able to `su` to an 
AD user on the CentOS server, but only with errors:

# su - DOMAIN\+testuser
id: cannot find name for user ID 16777216
-bash-3.00$

It seems to pass, but with errors. (I had to manually create the homedir 
for the user: /home/DOMAIN/testuser to get `su` to work.)

I can't seem to login to the server using the account, though. I've been
using a number of documents from Samba, O`Reilly, and other sources I 
googled up, but they are all pretty much the same. Am I missing 
something? Do I have to do something else to allow an existing AD 
account to log into the machine?

Here's my config:

smb.conf:

    winbind use default domain = no
    password server = pdc.addomain.mydomain.com
    realm = ADDOMAIN.MYDOMAIN.COM
