Hi, we are testing PHP7 with our Moodle 3.3 installation. It seems that everything is fine, but we are having problems with user validation. We use the CAS plugin. And the plugin is deactivated and it does not let users authenticate.
Apparently, it happens when it is deactivated for security when it has a certain number of validation failures. The failures must be some incompatibility with PHP 7. Do you have the problem?
Our installation is the typical nginx + apache + fpm. We thought that it could be due to use Redis for the sessions but with the sessions in file also happens.
The system Os is debian stretch with the system packages.
Greetings and thanks in advance.
