Jumping on this thread late but another product that is awesome for Unix AD 
integration is VAS or I guess now they are calling it Quest Authentication 
Services.  Just like Centrify only been around longer and is definitely geared 
toward the large enterprise.  

One thing I liked about is that they had a tool that resolved UID/GID conflicts.

We still have NIS+ installed across the globe, with most data for 
*everyone* (150K+ user accounts) replicated into the domain at every 
location. The exception is home directory information where we have a 
NIS+ automounter map for the home directories.

Most users have a single home directory in the location where they do 
most of the work (usually local to where they live). However, for users 
who do work in multiple theatres we can create separate home directories 
in each of those theatres. This usually happens only after someone 
complains about the speed (mounting a US-based home directory in Europe 
or India is painful!) and when authorised by management.Others just put 
up with the latency for occasional use 'across the pond'.
