Sorry I forgot to mention that the permissions on the Linux machine running the
Samba server are more similar to the ones when I mount the network drive without
the "noacl" option in Cygwin. 

This is the ls line from the Linux machine:
-rwxrw----  1 chris tech 1014 Dec 15 14:16 amssetup

On Cygwin without "noacl":
-rwxrw---- 1 ???????? ???????? 1014 2009-12-15 14:16 amssetup

On Cygwin with "noacl"
-rw-r--r-- 1 chris None 1014 2009-12-15 14:16 amssetup

So apart from the ???????? entries, I think going without the "noacl" option
would be the way to go. But I will give it a try with "noacl" and see if it has
any undesired side-effects.

Thanks
Chris
