Using cpanel auto password generator
Took me ages to realise the script didn't like the "$" in the auto-generated password
This could probably be linked to ID 3031023.
As long as the password is put inside single quotes, the $ doesn't get interpreted as a special character. The only thing then is to quote every occurence of ' (single-quote) inside the password, i.e. \'.
Furthermore the handling of variables has been cleaned up in version 3.0_beta.
