Re: Cygwin ssh and Windows authentication

Hi Andrey.
So why are they not needed as your comment doesn't really explain that 
and how exactly did I screwed up my setup if I can actually access the 
server with a domain user account no problem? Perhaps it's not how it 
works but it somehow works so again would be good to know why. It's only 
domain groups that don't work. Even if I set the service account to run 
under a domain account how would this fix my problem with group access 
assuming in current setup it works for domain users but not for groups? 
Again if not the /etc/passwd or /etc/group files then what controls the 
access?
