After some debugging I found that the explanation is that sshd drops all supplementary groups from the otherwise privileged user token. This results in a minimized user token when calling initgroups, which in turn calls NetUserGetGroups, which in turn returns "Access denied". The solution is to drop back to the original process token before calling NetUserGetGroups from initgroups. I've checked in a patch which should be available in the next developers snapshot from http://cygwin.com/snapshots/ A solid workaround if you're trying to get the same with the current Cygwin: Add all users which want to log in this way to the gr_mem field of the approrpiate groups in /etc/group. In your example case, it would look like this: Test Users:S-1-5-21-4293257363-1756470469-1603820055-1123:11123:test1 Corinna -- Corinna Vinschen Please, send mails regarding Cygwin to Cygwin Project Co-Leader cygwin AT cygwin DOT com Red Hat -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
