proftp with mysql db users quthentication
 

I'm using RH8.0
Mysql is installed and run properly
I installed proftpd 1.2.7 thru rpm package download from proftp offical ftp site

Is has no problem runninf proftpd using accounts from linux system account. i.e. /etc/passwd


Now I want to change proftpd to authenticate users from a backend database e.g. mysql


I create a user table as mentioned in proftp readme.mod_sql file

and I copied a proftpd.conf template and edit serveral directive that refer to db connection

e.g.

SQLConnectInfo proftp@localhost root


but when I restart proftp, it report an error

unknown configuration directive 'SQLConnectInfo' ...........


What's the problem ?
