[Samba] researching options need advice

[Aaron E.]

Our current infrastructure is Openldap back end with samba3 pdc. With 
2003 terminal servers Using poledit.exe with policies..

We are in need of upgrade of our terminal servers. I cannot get the old 
way of policies to lock the server down as I need to function on Windows 
Server 2008.

What are other people doing? I can't be the first one to run across this 
and can't seem to find anything substantial in googling.

Advice Greatly appriciated.
