10545 is usually "Domain Users" (the domain user and group ids are offset
by 10000 by default).  545 is local "Users".  4294967295 is really "-1" --
see <http://cygwin.com/cygwin-ug-net/ntsec.html#ntsec-ids> for an
explanation.  "getfacl" (or NT's "cacls") should give you the actual
owner/group.

To get the domain groups into /etc/group, use "mkgroup -d >> /etc/group"
(warning -- may take a *long* time in large domains).  You can give the
"-g" flag to mkgroup to extract specific domain groups.  Similarly, for
domain users, use "mkpasswd -d >> /etc/passwd" (same warning applies).
See "man mkpasswd" and "man mkgroup" for more information.
