I urge you to read the entire thread starting at https://sourceware.org/legacy-ml/cygwin/2016-06/msg00347.html There's a *LOT* of information in there in terms of discussing and creating the nobody/nogroup mapping. Bottom line is, there's no nobody account equivalent on Windows and no resolvable SID/Name pair. Thus, we decided to use the SID S-1-0-65534 mapped to uid/gid 65534 for this purpose. This doesn't matter to native Windows, it's just some foreign SID. But it's resolvable inside Cygwin: $ getent passwd S-1-0-65534 no+body:*:65534:65534:U-no\body,S-1-0-65534:/:/sbin/nologin $ getent group S-1-0-65534 no+body:S-1-0-65534:65534: Corinna -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
