How do you know sshd works?
Can you telnet into the box as a normal user?

Yes.

This starts well. login recognizes that SYSTEM exists and 
has no password.
The error comes from these lines in login.c

        if (seteuid(pwd->pw_uid)) {
		printf("Switching to user %s failed!\n", username);

So telnetd has the same problem as exim, it can't setuid, even
though in this case the setuid should be a noop. 

There is something wrong with your installation.
What version of Windows do you have? 
Does "ps -a" show that inetd has uid 18?
Does uid 18 appear several times in /etc/passwd ?

Same problem, probably.

That looks normal and not related to the problem.
Wait. What happened at 6:46 am? Did you login at the console
or did you do something else?
 
Is there anything in the application log?
Is there anything interesting in /var/log/xxx.log ?

Pierre (who sees it's 11:30 PM)
