Thanks for the good responses so far.  I was talking with a more "open 
minded" company AD administrator and he mentioned that a product called 
Centrify is in the currently "blessed" state and deployed to numerous 
high security PCI Unix servers in the company.  If Centify was installed 
on the RHEL Linux servers we hope to run Samba on, does this change the 
mix of steps or significantly alter prospects?
