Rudder

On SLES12 SP2, apache (which has a version of 2.4.23-something) is not starting after a clean installation and initialization of 4.1-rc1:

start_apache2[11305]: AH00526: Syntax error on line 97 of /opt/rudder/etc/rudder-apache-relay-common.conf:
start_apache2[11305]: Invalid command 'Allow', perhaps misspelled or defined by a module not included in the server configuration
systemd[1]: apache2.service: Control process exited, code=exited status=1

In "/opt/rudder/etc/rudder-apache-relay-common.conf" there is this section:

<Directory /opt/rudder/share/relay-api/relay_api>
  # Allow access from anybody
  Allow from all
</Directory>

This should be more like something like this:

  <IfVersion < 2.4>
    Order deny,allow
    Allow From all
  </IfVersion>
  <IfVersion >= 2.4>
    Require all granted
  </IfVersion>

This patch helped me start apache2 :
