Whenever you edit sshd_config, you'll want to restart sshd:  /etc/rc.d/sshd restart

Example sshd_config file, from a newly installed 6.0-RELEASE system:

 #       $OpenBSD: sshd_config,v 1.72 2005/07/25 11:59:40 markus Exp $
 #       $FreeBSD: src/crypto/openssh/sshd_config,v 1.42.2.1 2005/09/11 16:50:35

 # This is the sshd server system-wide configuration file.  See
 # sshd_config(5) for more information.
 
 # This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin 
 
 # The strategy used for options in the default sshd_config shipped with
 # OpenSSH is to specify options with their default value where
 # possible, but leave them commented.  Uncommented options change a
 # default value.
 
 # Note that some of FreeBSD's defaults differ from OpenBSD's, and
 # FreeBSD has a few additional options.

 # Change to yes if you don't trust ~/.ssh/known_hosts for

 # Set this to 'no' to disable PAM authentication, account processing,
 # and session processing. If this is enabled, PAM authentication will
 # be allowed through the ChallengeResponseAuthentication mechanism.
 # Depending on your PAM configuration, this may bypass the setting of
 # PasswordAuthentication, PermitEmptyPasswords, and
 # "PermitRootLogin without-password". If you just want the PAM account and
 # session checks to run without PAM authentication, then enable this but set
