Ron - I cannot find any evidence that 
MultiUserEnabled/EnableMultiUser/MultipleUsersOnConnection has been 
rolled forward into Windows 2008.  It's possible that the functionality 
was embedded in 2008 - but very unlikely.  Can you verify that your 60 
TS users are being serviced from one Samba smbd?  If you do not have any 
non-TS users connecting, then that is easy enough by doing a "ps -ef | 
grep smbd" and seeing if there are 61 processes or 2.  In the 
whitepaper, there are several workarounds suggested.

I'll see if I can find out from MS what the story is about 2008, but for 
2000 and 2003 it was a 3-year delay each time, as I recall.
