I honestly haven't read up exactly how Cygwin interprets NTFS ACL/ACEs, but I remember seeing on the mailing list that a change was made in 1.7.35 was made to permission handling. It is preferable in my organization that the SYSTEM account always have full control the local file system. When using chmod under 1.7.35, it looks like permissions for SYSTEM get stripped (as well as some others). Is this the desired behavior? If so, I'll workaround it somehow but just wanted to verify before we release this much anticipated Active Directory optimized version. For context, I'm running as the default Domain Administrator on a fresh install of Windows 8.1.
