Hi, I am testing Web Disk for suitability here but I would like to restrict each user to their own home directory (as specified in AD). I can see an option for homedir in web.xml but this still allows the user to browse the tree. It also only allows for a single server whereas my user home directories may be on 2-4 servers.
Is there anyway for me to accomplish this with Web Disk?
Thanks in advance,
