Hi all,
As everybody knows, to make APs join an aruba controller automatically, we always enable Control Plane Security and Auto Cert Provisioning both. But, since 6.4.x.x ArubaOS version released, I have encountered the same issue a few times that APs does not join Controller by enabling CPSec and Auto Cert provisioning. Everytime when I encountered this issue, I tried to disable CPSec and it worked. APs suddenly appeared on the controller. Does anybody know the reason about this issue?
