Ignore create ftp user and pass after create vhost

Hi All
I create Master ftp account to log to all domains that I created
every time I create vhost, they ask me to create ftp user name and password, so how I create vhost without create ftp user and pass

I try to stop ftp by this 2 commands

service pure-ftpd stop
chkconfig pure-ftpd off

after I do this I created a new vhost but ask me again to create ftp username and pass for this vhost
