Does OpenSSH have tcp_wrappers *built-in* or just compatibili ty?

On solaris 8, that would probably be something we could do. We're
looking into how we can limit specific users from being able to ssh out
of a box, and someone mentioned tcp_wrappers being built into OpenSSH. 

We'll check it out and see. Any ideas around limiting users from sshing
out btw? :) TIA
