PDC Functions

Well I am just trying to get the username mapping from SFU to work properly. 
  If I have a local user (ie: Administrator) to the machine, and create a 
mapping of any sort for it- no issues.  Maps perfectly.  If I try and do it 
with a domain user, it shows up in the list, I can even make an advanced 
mapping... however it will always create files as nobody if the user I'm 
trying to map with is in the domain.

Any way to emulate the functions of this said DLL in Samba?
