You'll need to set CYGWIN=smbntsec (plus whatever else you might be 
using) and "nt acl support = yes" in smb.conf for the affected shares.
Samba uses the "Take Ownership" nt property as a placeholder for no 
permissions, 0, when mapping unix permissions to ntacl's.  That gets 
interpreted by Cygwin as readable when CYGWIN=nosmbntsec the default 
behavior in 1.3.21 (what I have) contrary to what is documented.
