General :: Setup FTP User But Won't Connect?

I have a remote virtual server for a few websites, it's running on Fedora Core release 6 (Zod). I want to setup an FTP user so I can have someone do some work for me. He only needs very limited access. I have searched for help and thought I found out what I needed to do, but when I try to test the connection, after the password is sent I get the message "530 Login incorrect", followed by "Critical Error", "Could not connect to server". (I am using FileZilla for my FTP client) Below is what I did to add the user

Code: useradd -d /var/www/vhosts/mywebsite.com/httpdocs/thisisit -s /sbin/nologin myuser

"thisisit" is the name of the directory I want to give access to and "myuser" is the user I am adding. I use passwd myuser to add a password. I've tried -s /dev/null also (to prevent this user having shell access) but it's the same. The worse thing is, I did a similar thing last year for a customer so he could upload images to my site. That login works fine. I have looked at the passwd file and both users seem to be setup the same, yet the new user does not work. What am I overlooking?The two entries in my passwd file are The one that doesn't work

myuser:x:10025:10025::/var/www/vhosts/mywebsite.com/httpdocs/thisisit/:/dev/null And below the use I created lat year that DOES work. mycustomer:x:10008:10008::/home/ftp/mycustomer/:/dev/null
