When we try to search for users to enrol into an mnet course (through the remote enrolments client) the search returns no results. We believe this is to do with the number of users (we have 30,000). Another institution we are aware of has 10,000 users and a search for them takes 2 minutes to return a result. We are running Moodle 2.4.1.
Does anyone else strike this or have a solution?
