Bug#429619: openssh-server: password based authentication not working following upgrade
Hello,
it is still not quite right. To work around 4.6p1-1 bug I enabled
'PasswordAuthenticaion yes' in sshd config file, and it worked great.
But for 4.6p1-2 I'm prompted for password, and then thing crashes (Works
fine with key based authentication):
petr-dev3:/var/log# ssh localhost -l petr
Password:
Read from remote host localhost: Connection reset by peer
Connection to localhost closed.
petr-dev3:/var/log# tail auth.log

After I put 'PasswordAuthentication no' back into sshd config file,
things look better... (though I do not understand how PAM can work
without PasswordAuthentication, as server definitely needs my cleartext
password to be able to send it to PAM...)
