FTP access for users?

Hi all,

I'm trying to get FTP to work with Alfresco Community Edition 201602 GA Release (binary installation) on a VirtualBox Machine with Linux Mint 17.3 KDE.

I can access access Alfresco with Filezilla from a client but only for the admin. When I try to access Alfresco with another account I get following error in Filezilla:

Response: 530 Access denied Error: Critical error: Could not connect to server

In alfresco-global.properties I have:
ftp.enabled=true
ftp.ipv6=disabled
ftp.port=2021
ftp.bindto=10.19.75.21

How can I give access to Alfresco over FTP for users apart from the admin?

Thanks in advance!
