"Fri Aug  2 16:45:38 2013 : Debug:   WARNING: Unprintable characters in the password.  Double-check the shared secret on the server and the NAS!"

I really fail to see what's ambiguous about that error...

The shared secret on the NAS and the RADIUS server is wrong and it's failing to decode the user's password correctly. Make sure the shared secret is the same on the NAS and the relevant client in clients.conf.

Don't response with "but they're the same", because they're not.  You've either misconfigured the NAS or the RADIUS server.  We can't help you figure out which.
