This chapter in the new Cygwin 1.7 User's Guide is supposed to
explain what's going on when switching the user context from a
service like sshd:

http://cygwin.com/1.7/cygwin-ug-net/ntsec.html#ntsec-setuid-overview

Please read it closely, especially the section
http://cygwin.com/1.7/cygwin-ug-net/ntsec.html#ntsec-nopasswd1


Hope that helps,
