This is a call to the Win32 API call NetUserGetGroups creating an exception due to an "access denied". The difference between 32 and 64 bit is probably a result of the differences in exception handling, and given that an ExceptionCode 5 will be ignored by Cygwin's exception handler, it's probably the next handler in the chain. Are you running sshd under a local cyg_server account or under a domain cyg_server account? Is it possible that this is a local cyg_server account, and as a non-domain account actually gets an "access denied" when trying to request AD user information? If your cyg_server is a local account I'd suggest to try with an AD account per https://cygwin.com/faq/faq.html#faq.using.sshd-in-domain Other than that I have a funny idea how to workaround this problem from inside Cygwin. If you want to give it a try, I'll send you a pointer to a 32 bit DLL via PM. Corinna -- Corinna Vinschen Please, send mails regarding Cygwin to Cygwin Maintainer cygwin AT cygwin DOT com Red Hat
