The following page partially addresses this:

http://www.cygwin.com/cygwin-ug-net/ntsec.html

It says that:

--------------------------
If another user (or a Windows group, treated as a user) is not present
in /etc/passwd, the uid of that user will have a special value of -1
(which would be shown by ls as 65535). The user name shown in this
case will be '????????'.
--------------------------

I would like to modify the /etc/passwd file so that it shows me
as the owner of these files instead of '????????'.  That page
shows how /etc/passwd is used to create a mapping between Windows
Security SIDs and Cygwin uids.

How do I find/list the Windows SIDs of these files so that I can
create the proper mapping in /etc/passwd?
How about:

$ mkpasswd -d >> /etc/passwd
$ ls -l <file>

and see who owns it?

mkpasswd -d would return all of the domain users (we have thousands). However, I know that these files are not owned by anyone else. The files in question are coming from a samba share (mapped network drive) served from a Linux system.

Isn't there a way so see the SID of a file?
