dgü commented on SSHD-1281:
---------------------------
According to your last Bitvise SSH Server log, only password authentication is
attempted. But, in my case, public key authentication is done first, then
password based authentication is attempted.
That means your test and mine are not same.
Anyway, I am not focusing on the authentication. The authentication problem
looks like a symptom. The root cause looks that connection is ended before
authentication.
