AD Kerberos Ticket not functioning

OK, So I have finally got my AD binding for Leopard functioning properly. The first thing I then tried to do was single single sign on to an SMB share located on one of my 2003 Windows servers. I am immediately prompted for my username and password. I took a look at my Kerberos ticket agent and it looks like I received my ticket but my client is not password the information on to the server. Anyone run into this?
