vsFTPd configuration in RHEL 5.0

conf file: /etc/vsftpd/vsftpd.conf
Unlike SSH we are having two files to allow/deny users via FTP ( in SSH we did it in the main configuration file itself by AllowUsers/DenyUsers)
The main file for denial is /etc/vsftpd/ftpusers
The other file is /etc/vsftpd/user_list
But if we need to make our FTP check user_list file we need to say it in the main configuration file, like

If, userlist_enable=NO, ftp doesnt check user_list file

The behaviour of user_list depends upon the declaration inside the vsftpd.conf file

if its declared like,
userlist_deny=YES , those usernames inside user_list is denied even without prompting for a password
if its declared like,
userlist_deny=NO, those in user_list are ONLY allowed to login.

Whatever the behaviour of user_list, FTP searches for ftpusers file for users that are DENIED!
