LogonUser/CreateProcessAsUser need special user rights.  This rights
are not given to user accounts, not even to admins.  Only SYSTEM has
that user rights by default.  That's the reason that login only
works when started from telnetd or rlogind, started from inetd which
itself is running as service under SYSTEM account.

login(1) is not intended for use on the command line under Cygwin.

Shouldn't we create a FAQ for that?
