I have a bit of an authentication problem. I updated some packages on my Slackware64 14.1 system yesterday. Today, when a client was trying to WS-FTP to his account, he was blocked. The WS-FTP log is below. I've tried restarting openSSH. I can ssh to this account, but the client cannot WS-FTP. I'm sure it has something to do with the update, but I don't have any idea where to look. Need help
