Based on your last post, I am guessing there is a misconfiguration there. Pending that, you might look into possible configuration of AD preventing your version of Samba from working. Although you are using the CentOS 5 Config example, what distro and Samba package are you using? Out of curiosity, what client OS's are you supporting with this proxy?
