UsePAM, lack of permission denied messages after each failed attempting when

Hi,

Despite my best efforts, I cannot figure out how to get a "Permission 
denied" message after each failed password entry when configured with 
UsePAM.  As you can see below, it only says permission denied after 
three attempts and not after each one.

# ssh <ipaddr> -l josh
Password:
Password:
Password:
Permission denied (publickey,keyboard-interactive).

My sshd is OpenSSH_3.8.1p1, OpenSSL 0.9.7e 25 Oct 2004.

And my pam configuration looks like this:

auth    sufficient      pam_unix.so nullok_secure
auth    required        pam_radius_auth.so

Any help would be great.

Thanks,
Josh Rosen
