I also came across with the above error message while using ssh. I tried ssh in 2 machines in a loop. Only 1 showed(machine 21, below) the error. And in that machine(21)i had changed the password once before i ssh. So i think the error may be because of the password change.
Please note that ssh allows to login usig private/public key pair even after the password of the machine is changed. See below the results...
