That's what acl/noacl is for. See the user's guide:
http://cygwin.com/1.7/cygwin-ug-net/using.html#mount-table
With "acl" switched on, Cygwin uses what's returned by the file system
and in case of a Samba share the user and group are special SIDs
constructed from the OSes uid/gid values.
If you want nice entries in ls -l output, add the users and groups to
your local /etc/passwd and /etc/group files using mkpasswd and mkgroup
with the new -U options:
http://cygwin.com/1.7/cygwin-ug-net/using-utils.html#mkpasswd
http://cygwin.com/1.7/cygwin-ug-net/using-utils.html#mkgroup
For instance:
$ mkpasswd -U root,corinna -S_ -L my_samba_box
Unix User_root:unused:10000:99999:,S-1-22-1-0::
Unix User_corinna:unused:10500:99999:,S-1-22-1-500::
$ mkpasswd -U root,corinna -S_ -L my_samba_box >> /etc/passwd
$ mkgroup -U root,corinna -S_ -L my_samba_box
Unix Group_root:S-1-22-2-0:10000:
Unix Group_vinschen:S-1-22-2-11125:21125:
$ mkgroup -U root,corinna -S_ -L my_samba_box >> /etc/group
$ cd //my_samba_box/my_share
$ ls -l some_file
