For some reason proftpd stopped authentication for users. Anonymous access still works but when someone tries to access the server via their login it no longer authenticates them. I recently ran yum where proftpd was updated (that said, I'm not sure that caused the problem). I uninstalled the new version and and installed a prior version with no change. Below is a look at my config, a debug cut and paste and the current version I am running. This is a production server with a loss of revenue generation for the company and is imperitive that I get resolved asap. Any help would be appreciated! * Proftpd Conf:* # # This is the ProFTPD configuration file # $Id: proftpd.conf,v 1.1 2004/02/26 17:54:30 thias Exp $ ServerName "ProFTPD server" ServerIdent on "FTP Server ready."
