VPN PPTP or L2TP and Open Directory User Account

I called Apple support today for help with my VPN server running on Mac OS X 10.3.2. It was stated that this only works with Local Accounts and not with Open Directory Master User Accounts. It was also stated that I would have to pay extra for support with this problem. I guess my 1k was not enough to get good support. I was steaming by the end of the phone call. Well no matter what I have tried, I am unable to get local or ODMaster accounts to work with the VPN server. I would appreciate any help in this matter. Maybe I am just overlooking something simple. Just thought I would let everyone know this before they ran out and bought Panther Server for the VPN features.
