I use Cygwin 1.7 on my XP desktop system at work.  I like having the
same home directory on this Windows XP system as I do on our Unix
server.  The Windows XP system is a member of a domain.  The Unix
server is not.  The Unix server is running Samba and is configured
with a workgroup name.  My home directory on the Unix server is
mounted as a mapped network drive on the Windows XP system.

Everything in the above setup is working
properly from the Unix server side and from the Windows side when
working with Windows Explorer.  I can create and delete files via
Windows Explorer and they show up on the Unix side with proper
ownership and permissions (as controlled by Samba).  Conversely,
I can create and delete files under Unix and access these files
from Windows Explorer.

The problem is when I look at my mapped network home directory
with Cygwin, my home directory files are owned by nobody ('????????')
and have a group of nobody.  I am guessing that this is because my
Windows SID in /etc/passwd is the SID of my domain user and since
the Samba server is not part of this domain the files look like they
are from an unknown user.

In our Samba server there is a file (usermap) that maps unix usernames
to windows usernames.  This appears to be working when working with
Windows Explorer.  Why doesn't this work with Cygwin?  What is the
way to fix this?  Do I somehow need to map my unix username to a
windows SID?  Do I need to turn off ntsec?  Do I need to change
the mount options for /cygdrive?
