I have just setup some new sites (on the same client). I have set the same password for 2 different FTP users for 2 different sites (let's say user FTP-A for site A and FTP-B for site B), but I gave both accounts the same password. The funny thing is that logging in with user FTP-B led to site A. After I changed the password of FTP-B, connection was properly made with site B. So there seems to be a bug in the login process on the FTP server. (I am using pure FTP from Falko's perfect server setup with Debian Lenny) => workaround: always give different FTP passwords for every single account. => possible todo for ISPC: make sure a password is not given out twice. Now I remember that I was surprised that Plesk did not allow two accounts with identical passwords - this may be the cause.
