Description of problem:

/etc/httpd/conf.d/glpi.conf still contain this:

<Directory /usr/share/glpi/config>
    Order Allow,Deny
    Deny from all
</Directory>
<Directory /usr/share/glpi/locales>
    Order Allow,Deny
    Deny from all
</Directory>
<Directory /usr/share/glpi/install/mysql>
    Order Allow,Deny
    Deny from all
</Directory>
<Directory /usr/share/glpi/scripts>
    Order Allow,Deny
    Deny from all
</Directory>

These ACL should be replaced with an apache 2.4 aware variant,
 <IfModule mod_authz_core.c>
     Require all denied
 </IfModule>
 <IfModule !mod_authz_core.c>
     Order Allow,Deny
     Deny from all
 </IfModule>

Version-Release number of selected component (if applicable):

glpi-0.84.3-1.fc21.noarch.rpm

(affects EPEL too)
