Using ProFTPD I have my users jailed to thier home via ftp and a group that can traverse all directories. I want to jail this group to /home though so members of it can't get into the rest of the file system. Any suggestions as to how I can make that happen?

Here is the line from my proftpd.conf:

# Use this to jail all users in their homes 
DefaultRoot                  ~ !ftp-super
