GLPI has introduced a router in their configuration that displays a warning in the front page relevant to a not secure settings for web apache service
we need to leave the web folder that you know (http://IP/glpi) to a virtualhost.
For compatibility I continue to follow the web folder (/glpi) mainly also if you have configured many many glpi agent or ocs inventory
the way to go to the virtualhost is
config setprop glpi DomainName glpi.ns7loc.org
signal-event nethserver-glpi-10-latest-update
after that you will need to fix each agent with the new URL or you could live with the warning
Of course you could go back to the default web folder /glpi
by
config setprop glpi DomainName ""
signal-event nethserver-glpi-10-latest-update
