we were replacing the securelogin.arubanetworks.com url that is used for captive portal redirect between clearpass and aruba controller.
We used the already installed certificate on the controller that has 4 common names/alternatives in it.
When doing the redirect from clearpass we get a host cannot be found DNS error. This means the controller is not picking up the dns query for some reason, We suspect that its because of the 4 common names that we have in the certificate. Did someone already try to put a cert with alternative names on the arube captive?

Subject alternative names will not be available for use during captive portal authentication. You'll need either a wildcard or standard certificate. Please see here: https://community.arubanetworks.com/t5/Controller-Based-WLANs/ArubaOS-Default-Certificate-Revocation-FAQ-Controllers/ta-p/275809
