ssh and chrootusers returns 'bad configuration option' please advise

Hi debian list, 

I'm not currently subscribed so please reply to the email.

i have a current woody machine with openssh 3.4p1 and it's not allowing
me to use the ChRootUsers option.  When added to the conf file, I
restart and get bad configuration option: chrootusers.  What's wrong
here?

http://www.ssh.com/faq/index.cfm?id=687 says that's the syntax.

My ssh by oreilly book says the same thing.  

The goal, you must know by now is to jail users to their home directory.

Please advise!

Regards, Justin
