This is covered in the FAQ somewhere I think.

Windows requires the user's password in order to do true user context
switching.  So when you log on using public key auth, Cygwin can only
partially impersonate the user account.  Things such as protected
network shares will not work.  There's no way around this short of using
password authentication, because it's a fundamental windows requirement
that the token contain the password.

You should be able to use editrights to assign the necessary
privileges.  Read /usr/share/doc/Cygwin/*openssh* and the contents of
