Enable LDAP Nextcloud in hosting (cannot run any commands)

Hello,
Time ago I implemented a NextCloud instance in a web-hosting environment integrated with Microsoft Entra SSO and LDAP to enable our company users to get access on it. Nextcloud Server Version 28.0.4

Now I’m trying to create a second instance (updated Nextcloud Server version 31.0.2) totally separated from the first but I cannot enable the LDAP user and group backend with the error: The library ldap is not available.

I read many post here in the support forum which I have to run commands like yum install php-ldap but, as I’m in hosting, I don’t have access to the server. The same situation in old Nextcloud which I was able to use LDAP/AD Integration application.

Thank you
