[tz] iana.org ftp asks password

hello, I just noticed that ftp://ftp.iana.org/tz/releases/ asks for a password I doubt this is intended. it might be good to list ftp://ftp.iana.org/tz/releases/ on http://www.iana.org/time-zones as a way to retrieve old versions ( I hope that's still possible, it's sometime handy to see what changed) Regards, Gunther
