Subject: Re: Can SSH from localhost as Admin but NOT 'regular' user when using passwords
From: Evan Rowley <rowley DOT evan AT gmail DOT com>

Andrey Repin,

Some english is better than none! With Russian, I have a lot to learn still.

Interesting is that on both installations of Cygwin, /var/log/sshd.log is
empty. I've followed to basic steps to install Cygwin, setup users, and
setup sshd. Maybe there is another step for logging that I missed?

I can give the output of attempting to ssh to SFTP_User:
