[wu-ftpd-2.6.1] ftpaccess configuration

I`ve a big problem with the configuration of the ftpaccess file. I want to create 2 guestusers with different delete permissions and a limit to enter the server. My ftpaccess looks so in the moment: --------- class accounts guest *class admin real *guestgroup mp3sguestgroup backups realuser ftpadminlimit mp3 1 Any /etc/volllimit backup 3 Any /etc/volldelete no backups delete yes mp3s--------But this doesn`t work. I`ve read this in a tut.Can you say me, what i do wrongPs: I know that wu-ftpd is not very secure, but in the moment i can`t install another one.
