I am running Ubuntu Server 9.10 with ProFTPD, and I also have Webmin.
I have DNS setup for 3 domains, mail setup for 3 domains, as well as Apache2 setup for those domains. They work great.
Now I want to give FTP access for an incoming user, but point them to /var/www/[domain] and have them come in as something like user "ftpuser" but want this to translate to user "www-data" so that web permissions will be correct.
What is the technique to do this?
