Product and Software: This article applies to ArubaOS 3.x and later.
When you import a new certificate, the current users are not kicked off. The imported certificate takes effect only after you map it to the profiles.
If the imported certificate does not work, remap it to the default profile to work around the problem.
This solution applies to any certificate uploaded to the controller. After you map the appropriate certificates for 802.1x, captive portal, and GUI, login works after the profiles are mapped.
