Shared Roaming Profile

I am setting up a demo Mac OS X Server set up, showing how we can use our current OS X servers as a Primary Domain Controller for the various PCs (all on XP) in our school district. Here’s what I need to find out. I want four roaming profiles. One for Admins, one for Teachers, another for Students, etc. This way, if students need access to another app (that is distributed via ghost), we can add a shortcut to the desktop extremely easily. My Documents is not a problem as it is mapped to an H: drive which points to that user’s Mac OS X Home directory. So, in order to do this, apparently, the user logging in must also be the owner of the profile. Is it possible to set multiple users or an entire group (preferable) as an owner? How would I do this? When the user is not set as the owner, windows XP says upon login: “Windows XP did not load your profile because a server copy of the profile folder already exists that does not have the correct security.” (Now I’m paraphrasing) “The owner of the profile must be the current user or the Administrator’s group.” I tried setting “Group:” to staff/admin as well as setting owner to root or to the Directory Administrator. Neither worked.

Any ideas would be greatly appreciated.

edit: here’s the exact error: “Windows did not load your roaming profile and is attempting to log you on with your local profile. Changes to the profile will not be copied to the server when you logoff. Windows did not load your profile because a server copy of the profile folder already exists that does not have the correct security. Either the current user or the Administrator’s group must be the owner of the folder. Contact your network administrator. “
