OpenSUSE Install :: Chroot Permissions At Login?

I'm trying to get it so that for a particular user, at login, they are chrooted to a specific directory. I've set up the directory and everything such that I think it should work. I wrote a new login shell that chroots the user and set it to be the login shell for that user in yast. Everything works great, except that when the user logs in, it asks for two passwords : the user's password, and then the root password (because chrooting requires su privileges). Is there a way around this? This is what my login shell looks like:

Code:
#!/bin/sh
/usr/bin/sudo /usr/bin/chroot /home/raid/dictation /bin/bash
