samba - Aug 2005 - R: Problem logon from a Windows Server 2003 by a RDPConnection

Has anyone come up with a solution to this?  I'm preparing to set up a 
Win2K3 Terminal Server on a Samba-3 domain.  I noticed at least two 
people with this same issue, but so far no documented solution.

Samba-3 on CentOS 4.1 comes with a Windows registry hack that seems to 
allow multiple users to each have their own connections, but that is the 
absolute extent of the documentation.  It doesn't indicate which version 
of Windows Server it's intended for, or if it's intended for a Samba
PDC.

Is that registry hack the solution to this problem?

Thanks!
