We will be implening Aruba solution with a pair of 7205 controllers and another with IAP Virtual Controller and a single Clearpass server.
There will be 3 SSIDs with: 1.Captive portal guest authentication, 2.AD Credentials authentication and 3.Client-Server Certificate authentication.
What will be the controllers behaviour if the ClearPass connection is lost? How long will the users stay authenticated in each of the 3 options.
