AD/OD/….and Ubuntu?

Hey AFP548 Family, Im hoping this type of question is has a place in this section, forgive me if it does not. I am an admin for a complete AD/OD network. Authentication done with AD and home folders hosted via OD. I have been playing with linux for a number of years and one distro that has caught my eye as viable addition to this setup from a cost perspective is Ubuntu Hardy Heron. I have been able to join my Ubuntu system to the domain and can log in with my AD credentials. However when i log in i don't seem to see my home folders (we have AD doing folder redirection to the AFP home folders for Documents and Desktop). I would like to be able to login and see my desktop documents the same way i do in OS X and Windoze. I feel being a hybrid environment should include any type of OS being able to join the network and operate in roughly the same manner. Any help on the topic would be much appreciated.
