Samba Server is not accepting Domain Joins from any Clients

I have been trying to get a Samba server up and running for a while now. For some reason it is not allowing any of my clients to join the domain. The samba and ldap backend are running on the same machine. TLS is setup on the server but is not used in the ldap.conf and smb.conf since they are located on the same server. I can add/modify users/computers using the smbldap-tools with no problems. I can browse the shares from my linux clients but not from an XP client. I have posted some join commands and their respective output below. Any help would be greatly appreciated.

Server info:
OS: Ubuntu 9.04
Samba Version: 3.3.2
OpenLDAP Version: 2.4.15

smb.conf:
# Samba config file created using SWAT
# from UNKNOWN ()
# Date: 2009/06/10 16:40:47
