[Solved] another proftpd issue (authentification issue)

[yohann]

ok,
i'm sorry guys, i can't make it work!
i did the fallowing:

edit /etc/proftpd.conf

uncommented de line #Include /etc/proftpd/modules.conf" at the beggining of this file
change mypassword

then i connected as root to mysql, executed the fallowing command:
SET PASSWORD FOR 'vftp'@'localhost' = PASSWORD('nouveau_mot');

then exited mysql

tryed to reconnect with my new passowd from the shell
it worked.

then i restarted proftpd
i still can't connect.

so i stopped mysql: /etc/init.d/mysql restart.

then i started mysql --log=/var/log/mysql/mylog

then i connected again to mysql from the shell just to see loging worked.
it worked.
so i restarted proftpd again.
then try to connect from a ftpcllient.
and i can't see any new query in /vaar/log/mysql/mylog

so i guess i have a probleme to connect to the database.
but what is it?

Again thank you for helping me

edit: also i've checked the file /etc/proftpd/module.conf, and i see both LoadModule mod_sql.c and LoadModule mod_sql_mysql.c

edit: i've also tried to uncomment the MysqlBackend line, but it doesn't changed anything
