[Samba] smbd process per user ( Samba 3 + Terminal server )

[Eric Roseme]

I would have asked if you tested on NT4 or W2000, but another Samba 
lists reader emailed me directly that EnableMultipleUsers is now 
implemented on W2003.  So I configured it on my W2003 PDC (I no longer 
have any NT4 or W2000) and it works (see below).  Both sessions 
originate from the same Terminal Server, and they start individual smbd 
daemons on the Samba server.  So maybe you do not have the hotfix or 
servicepack or something.  Here is the url to the W2003 instructions:

I'll edit my paper to include W2003 and re-post it.
