Lufang,

Cygwin's login is used to switch user context.  On NT, a special privilege
is needed for that.  Without that privilege, a call to switch the user
context, even to that of the current user, will fail.  By default, only
the LocalSystem user has such a privilege (thus, login can be [and is]
used by programs like telnetd and sshd).
	Igor
P.S. Why would you want to switch the user context to that of the
*current* user, anyway?
