Unattended installation of a Centreon Remote

Is is possible to use unattended.sh to install a remote server?https://github.com/centreon/centreon/blob/develop/unattended.shReading both documentation and code, I see one difference:During web installation, it is not necessary to install Autodiscovery module:https://docs.centreon.com/current/en/installation/installation-of-a-remote-server/using-packages.html#web-installationIn the code, I see ‘process_step8.php’ with something about Autodiscovery:https://github.com/centreon/centreon/blob/a609307ce94937b06157f479b66a14ae5ec465bf/unattended.sh#L647There are other difference or attention point?

Using AD groups for Permissions to Centreon

This might be a silly question, but we are trying to get permissions working with AD groups. We’ve got everything setup and if we add by user account everything works fine with the Access Groups, Resources, etc.. However if we try and add a AD group, no one can login. I’ve tried many different combinations and locations where to add this group but nothing seems to work. I assume based on the Users, and the filter string that groups do not work, is that correct? Or is it something I am just missing on how to assign permissions to AD groups?Thanks in advance, Matt

Problème "La connexion a été réinitialisée" sur l'interface web Centreon

Bonjour,Je suis en train de tester des plugin packs sur mon serveur de test, jusqu’à hier tout marche bien.Mais depuis ce matin j’ai un problème étrange en modifiant un hôte ou un service. En fait si je clique sur “sauvegarder” après avoir modifié la conf d’un service ou d’un hôte, j’aurai un écran comme ça :Par contre je peux modifier les conf de “Notification”, “Utilisateurs”,etc. Ce n’est que la conf dans la partie “Service” et “Hôte” qui me pose problème.Est-ce qu’il s’agit d’un problème niveau BDD?Merci d’avance.

Installation phpmyadmin

Bonjour,Ma question n’est pas directement liée à centreon mais je pense pourra aider les non expert de Centos.J’utilise Centreon 21.10 (ISO 21.04 de base).Il y a quelques mois j’avais réussi à installer phpmyadmin non sans mal …En utilisant les packages rh-php73 etc… j’ai supprimé php 7.3 depuis, j’avais plusieurs versions de php en fait. J’avais du mettre une conf php ici : /opt/rh/httpd24/root/etc/httpd/conf.d sinon phpmyadmin ne marchait pas. J’aimerais éviter d’avoir de nouveau plusieurs versions de php.Tout semble fonctionner normalement, je suis en php 8, sauf que phpmyadmin n’interprète plus le php (page blanche, juste le html)Comment faire pour que phpmyadmin trouve php correctement ?Merci

Apache security vulnerabilities CVE-2021-44790 & CVE-2021-44224 impact on Centreon's product

SummaryA zero-day exploit for a vulnerabilities in Apache versions less than 2.4.52 (CVE-2021-44790 & CVE-2021-44224) was publicly released on December 23rd, 2021. A detailed description of the vulnerabilities can be found here:CVE-2021-44790 CVE-2021-44224Centreon conducted an initial assessment across the codebase to determine the impact of this vulnerability. Impact CVE-2021-44790 A carefully crafted request body can cause a buffer overflow in the mod_lua multipart parser (r:parsebody() called from Lua scripts). The Apache httpd team is not aware of an exploit for the vulnerabilty though it might be possible to craft one. This issue affects Apache HTTP Server 2.4.51 and earlier. Centreon does not use mod_lua for its default Apache configuration. If you have not added a third-party configuration, no impact is to be reported. CVE-2021-44224 A crafted URI sent to httpd configured as a forward proxy (ProxyRequests on) can cause a crash (NULL pointer dereference) or, for configuratio

When I configure my configs.xml file, I add an input like this:<preference label="List Host Name" name="list_host" defaultValue="" type="hostMulti" header="Test"/>When i fill it in like this and click on apply, host id are sent. But when I go back to widget preferences,  hosts I entered have disappeared and I get this kind of error :You should know that when I only put one host in the input, no error is displayed the input of the hosts does not work, but the input of the hostgroups (bellow) works very well.<preference label="List Hostgroup Name" name="list_hostgroup" defaultValue="" type="hostGroupMulti" header="Test"/>Do you have any idea where the problem comes from?
