I got a web service working for core_user_get_users_by_id. But the username doesn't show up. I see that it's due to Moodle's default security config. Where can I go to change that security config so that the username shows up?
I'm trying to get the username for my LTI external tool. Since the basic LTI doesn't provide the username by default, I'm trying to use a web service to get it. Or is there any other way to get the username for the LTI external tool?
