I can vouch for Likewise Open just working. However, it too is based
on Samba and based on the OP's information, he should be able to
achieve deterministic UID/GID numbers across his system with standard
OS packages only if that is his goal.
That said, if you have a variety of platforms and OS'es to support,
Likewise is a great option... (never tried Centrify)
