Users Immediately disconnected

I am using the installer for Linux on CentOS 4.4 and it starts the server just fine, the web interface works and I have created a number of users on the latest version. However, when trying to connect someone is immediately disconnected with the following message in the logs. I'm hoping that I'm missing something simple here:
