That's what acl/noacl is for.  See the user's guide:

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:

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
  -rw------- 1 UnixUser_corinna UnixGroup_vinschen 172 2009-09-22 16:27 some_file
