samba - Nov 2009 - Problems with samba 3.4.3 as PDC for Windows 7

Hi all, I am testing Windows 7 Ult with Samba 3.4.3 as a PDC for Windows
7.  I am using a simple, smb.conf file, domain name is "mygroup"
without
the quotations.  Windows XP clients can join correctly and login as
normal.  However, with Windows 7, I can get the client to joint the
domain, but when I reboot, I get a machine trust error and the user can
not log onto the Windows 7 client.  

Here is the error in /var/log/message:
