I am running RHEL 6.7 with the following configuration for sshd#   $OpenBSD: sshd_config,v 1.80 2008/07/02 02:24:18 djm Exp $# This is the sshd server system-wide configuration file.

Bad configuration option: AUTOCREATE_SERVER_KEY
rhel;configuration;sshd
Because the AUTOCREATE_SERVER_KEYS is valid not in /etc/ssh/sshd_config file but in /etc/sysconfig/sshd
