In the course of our 802.1x deployment, we have found that we need to account for the ability for users to authenticate to a system they have never used before, meaning they do not have a local profile. To do this, we have implemented an unauthenticated VLAN that Windows systems will be a part of, which will be replaced by the roles that are handed back upon successful Active Directory authentication. But, the issue we are seeing is that the MAC address is constantly being passed to CPPM, sometimes multiple times in a 1 minute period (just looked at one sequence, 35 times in one minute).
Is this an effect of Windows trying to authenticate the systm onto the network, or maybe the Aruba 2920 switch configuration missing something that would prevent this from happening?
