[CentOS] Kerberized NFS4 w/AD 2008 R2

Is anyone currently using CentOS 5.5 with 2008 R2 AD authentication and a 
fully Kerberized NFSv4?  If so would you mind sharing your configuration 
with me?

I have been able to successfully get it working with Windows 2003 as 
discussed earlier on the list

http://lists.centos.org/pipermail/centos/2010-July/096374.html

With the exception that I had to use dynamic UIDs on the machine since we 
don't have Services for UNIX installed.  Instead of going with a long 
drawn out certification of Windows 2003 R2 w/SFU, we plan to target our 
deployment in line with our Windows 2008 R2 campus deployment.

I have followed everything that I did with Windows 2003 to get it working 
but NFSv4 w/Kerberos doesn't seem to work with 2008 R2 at all.  No matter 
what I try I consistently get

WARNING: Client not found in Kerberos database while getting initial 
ticket for principle NFS/hostname at DOMAIN using keytab

or

ERROR: No credentials found for connection to server

any help would be appreciated.  I've been banging my head against a wall 
for a while now and may have damaged to many brain cells to see what's 
going wrong.
