Should the group of my user be None?

Should the group of my user be None?

[Theodore Si]

Hi all,

I just installed cygwin on my Windows 8.1 laptop and I found that
the result of ls -l is like this:
-rw-rw-r--  1 Theodore None 0 Nov  8 22:44 a
And I fond that I am in several groups
$ groups Theodore
Theodore : None root Performance Log Users

This raise my curiosity because when I use git, I got some error.
Then I read this:

http://stackoverflow.com/questions/9561759/why-cannot-chmod-in-cygwin-on-windows-8-cp

I wonder why I need to use chgrp to make it right? Is this a bug?

Thanks
Theo

Shouldn't I be in the group with the same name of my username, like in 
Linux?

No.  It's Windows (same difference? ;-) ).  See:

No.  Windows isn't Linux.  Of course, if you want to make a group with your
user name and add your user to that group, Windows will probably let you do
that.  But that's not a convention for user accounts on Windows.

Thank you for your replies.

The permission of files under ~/.ssh can't be changed to 600 when their 
group owner is None. I have to chgrp -R Users (or Administrators, or any 
other group name other than None) ~/.ssh to make it possible to run 
chmod on them. I suppose this is a bug of cygwin on Windows 8/8.1 ?

I changed my GID in /etc/passwd from 513 to 544 to make my primary group 
Administrators. Now the group owner of the files are turned to ????? . 
Is it OK to do this?
