We are working with a department that is trying to use the screen sharing via an iPhone/iPad within Zoom. The MAC address of the wireless device hosting the meeting is registered as a device and sharing is enabled and set to share with access points in the same classroom. We are trying to understand what triggers a device to complete an [Airgroup Authorization Service] entry within ClearPass. We have seen an issue where the sharing does not work until the Authorization is completed. This makes sense as it needs to be added to the system as an Airgroup server. We have seen a host that is not listed as an Airgroup server until we force a reauth on the host ( AAA delete user on the device from the controller). We then see the AirGroup Authorization shortly after the 802.1x for the device. We are using AOS 8.10.0.6 and ClearPass 6.9.13.138003
