I added an user via the 'adduser' command but it cannot login via SSH..? When I try to login over SSH it keeps saying that the password is wrong. This is on Ubuntu Server 12.04
PS. Adding 'AllowUsers USERNAME' to /etc/ssh/sshd_config is a bad bad idea.. Was unable to connect to SSH at all aftwards (Connection Refused). Had to use OVH's Rescue mode.
