Hello, I am quite new too moodle so please be easy on me for this question.
I've been trying to find a solution for multi-tenancy but installing multiple moodles is a bit too much for now. So I come to create a category for each school. Then I set the group mode for each course inside that category as separated group. However, by having an url from to that category, unauthorized people still able to see the category name and courses names inside. What I really want to do is to make the whole category kind of invisible from people who do not belong to this category. By saying invisible I really mean invisible such that people outside does not know that it even exist, no display of category game, no course details and such. It should give a 404 respond to an unauthorized person when they try to access. Can anyone give me suggestions ? Much appreciated
