A required privilege is not held by the client.
Does this ring a bell? More below.

I love the last two users... Oh, what a great license does XP come with! :-)

Cygwin only uses the underlying Windows API, and thus comes with most of
its limitations (unless they are explicitly fixed, which is not the case
here).

Because normal users (read: anyone but SYSTEM) don't have enough
privileges to switch users. Starting with Win2003, not even SYSTEM has
the needed privileges by default. For more information, see
/usr/share/doc/Cygwin/openssh.README.

Run them as SYSTEM. IIRC, su is broken under Cygwin altogether. login
does work, however, as long as the user has appropriate privileges.
> Even better question: How can I switch users?
Install the openssh package, set up sshd (using ssh-host-config), and use
"ssh [EMAIL PROTECTED]" in lieu of "su - user".
