FreeBSD - Creating FTP account with adduser

Hi,

I want to set remote FTP backup of one of my server to another.

So i created a system user in SSH with adduser.

I am able to FTP login with this user and password on cpanel server running CentOS.

But i can't FTP login with system user i created on FreeBSD server. I am able to SSH with the user i created, but it is not allowing to login with FTP.

I know i can create a website and use its FTP for remote backing up, but i don't want this backup again considered as a website and backup again.

Is there any way to fix this problem ?

Regards,

Yujin
