I'm not quite sure whether this answers my question. To be able put a 
script into /etc/postinstall there has to exist a cygwin installation on 
the machine or /etc/postinstall wouldn't even be there to drop something 
in. I wondered if the way this previously existing cygwin installation was 
created had any influence on the outcome of the test.

Anyway, here's what I did:
W2k Server SP3, domain member, old cygwin moved out of the way, registry 
keys deleted, CYGWIN unset.
- Download setup.exe from cygwin.com (version info on welcome screen says: 
2.249.2.10),
- start setup.exe as non-privileged domain user,
- "Install program as..." box comes up,
- use credentials of local admin,
- select some packages,
- setup completes without visible warning,
- /etc/passwd and /etc/group contain all local users and groups but, as 
expected, no domain users / groups,
- most files are owned by local admin group, group is set to users (also 
local).
So, setup seems to have done it's job as good as can be expected when run 
by a user with local admin but no domain rights.

- create /etc/postinstall/testchown.sh with the contents you posted,
- chown it to 544:545,
- chmod it to a+rwx,
- start setup.exe as non-privileged domain user,
- "Install program as..." box comes up,
- use credentials of local admin,
- leave package list as is,
- setup says that nothing was to be installed,
- in /etc:
$ cat testchown
uid=500(mks) gid=513(Kein) groups=513(Kein),544(Administratoren),545(Benutzer)

(Admin account is renamed, as you see)

$ ls -l testchown
-rw-rw-rw-    1 SYSTEM   SYSTEM         79 Mar 17 22:58 testchown

I hope this will help.

Regards
   mks
