AD InetOrgPerson Vs User and network mounts

I've been bashing my head against a few problems and I'm hoping some awesome person here will help me with one or more of them. I have a AD/OD setup arrived at by loosely following the Bombich paper and borrowing a bit from the Rennich paper. I am also working on Netbooting all of my lab clients and making them managed clients. Here is my setup: Windows Server 2003 SP2- Active Directory Mac OS X 10.4.10- Open Directory In the "Golden Triangle" Configuration Around 16 client Lab Macs some intel, some not, all with OS X 10.3 or higher. The mac I am using for a test lab machine is an intel imac (one of those flat panel jobs) with 10.4.10 What works: Macs authenticate against AD, Single Sign On works, my test Mac does this while netbooting. Problem #1 The macs will let a AD InetOrgPerson log in and Access both AD and OD resources however Home folders will not automount. Other automounts wont mount either. This problem does not happen for 'Users' The distinction between Users and InetOrgPerson is lost on me but for some reason my predecessor decided that certain users should be one and some should be the other. Is there a way to make Mac want to treat these two the same? Problem #2 Some of the macs in the lab will refuse to let a 'User' with a network home login with an error saying that the home folder is on a network share. The share is available and other macs can mount it no problem. I have not been able to track down what configuration is different. Again, my predecessor configured these. I could just wait till I get a working config and netboot them all, but i really want to figure out why this happens. .
