sshd automatically close connection after successful login

["Ling F. Zhang" <lingfengz at yahoo dot com>]

I just installed cygwin. Ran ssh-host-config -y
and cygrunsrv --start sshd

and when i attemp to log in with "ssh localhost"
I was asked for password, then a "Connection to
localhost closed"

ssh -v localhost gives:

$ ssh -v localhost

/var/log/sshd.log is empty

I have no idea what's causing this. Searching cygwin's
mailing list, i can't find related problem either.

Any ideas?
