WordPress 2.7 Auto-upgrade

Hi,

I see some fields to be filled about the auto-upgrade since the 2.7 version. It asks me a hostname, login and password. I guess I have to enter the information for the current FTP server where my blog is installed, is that correct?
Then, I entered everything correctly, but it tells me that my parameters are wrong. Any idea why ? Maybe there is an error log somewhere ?

If I look at the FTP server logs, it tells my password is wrong, but it’s not… maybe it’s because I have special characters in my password ?!

Thanks
