A file has an owner, which is any security principal (again, can be a group). A file also has a primary group, but I think NTFS enforces this to actually be a group and not a user. By default, Win32 frequently makes the Administrators *group* the owner of any file created by any member of the Administrators group. Typical ACLs would have two entries: an ACE for the Administrators group and an ACE for Everyone. Cygwin has to somehow map those two ACEs into the classical Unix mode bits; something someplace is *always* going to appear odd when an ACL doesn't have exactly an ACE for the owner, an ACE for a group, and an ACE for everyone/authenticated users/whatever cygwin thinks "Unix Other" maps to.
