              Because PAM challenge-response authentication usually serves an
              equivalent role to password authentication, you should disable
              either PasswordAuthentication or ChallengeResponseAuthentication.
 
              If UsePAM is enabled, you will not be able to run sshd(8) as a
              non-root user.  The default is ``no''.
 
+     UsePAMCheckLocks
+             When set to ``yes'', the checks whether the account has been
+             locked with `passwd -l' are performed even when PAM authentication
+             is enabled via UsePAM.  This is to ensure that it is not possible
+             to log in with e.g. a public key (in such a case PAM is used only
+             to set up the session and some PAM modules will not check whether
+             the account is locked in this scenario). The default is ``no''.
+
      UsePrivilegeSeparation
              Specifies whether sshd(8) separates privileges by creating an
              unprivileged child process to deal with incoming network traffic.
              After successful authentication, another process will be created
              that has the privilege of the authenticated user.  The goal of
              privilege separation is to prevent privilege escalation by
              containing any corruption within the unprivileged processes.  The
              default is ``yes''.  If UsePrivilegeSeparation is set to
