Since manually downloading and upgrading my ISPConfig 3.0 installation to 3.1 beta, all FTP users have stopped working, trying any of them leaves the following error in /var/log/messages: Code: Jun 8 12:01:47 appserver pure-ftpd: (?@10.20.30.40) [INFO] SSL/TLS: Enabled TLSv1/SSLv3 with AES256-GCM-SHA384, 256 secret bits cipher Jun 8 12:01:47 appserver pure-ftpd: (?@10.20.30.40) [INFO] PAM_RHOST enabled. Getting the peer address Jun 8 12:01:55 appserver pure-ftpd: (?@10.20.30.40) [WARNING] Authentication failed for user [ftpuser] Changing the password of an FTP account to a new one does not help. I had the web interface login error as well, so I have already executed ispconfig_update.sh (git-stable) twice, once without reconfigure database, then with reconfigure. Neither of them helped.
