[BusyBox] Chroot problem

[Stéphane Esté-Gracias]

	Hello,

I'm using BusyBox and Tinylogin. A special user have to be chrooted 
to /var/captive.

I have set 'suid' to /sbin/chroot without an error occured (permission 
denied).

I have created an user with command :
	# adduser -h /var/captive -s /sbin/captive

Where "/sbin/captive" script is following :
	#!/bin/sh
	exec /sbin/chroot /var/captive /bin/sh

User is rightly chrooted but it has 'root' privileges.

I don't want this user have 'root' privileges : what have I missed ?

	Regards
