I'm not sure if this is possible or not. I'm running an Ubuntu Server 11.10 and have set up a Subversion repository in /home/svn and I have an sftp folder in /home/ftp.
My users can access each fine from the client side using ssh keys. I found that when using the ftp client they could browse the entire server, so I added these lines to my sshd_config file to have my users jailed to the ftp folder.

The problem is they can't access the subversion repository. Is there anyway of getting something like this working?
Here is the sshd_config file
