We have recently implemented air server into our network at our school on the teachers stations, we have the PC's setup to broadcast themselves, we have found the problem with this is that students can see the PC's and can request a code to connect to them which displays the code on the screen and will disrupt lessons and if they are in the room they would be able to see the code enter it in and display their idevice. This will cause a lot of problems and i was wondering if there is a way to authenticate which users can request codes, or maybe change it so it isnt an open broadcast and it can be contained or even if only specific devices can be connected and we have to program in their mac address??
