Delete a trusted root certificate for a RADIUS server only when you are certain that it is no longer required, for example, when the certificate has expired and a new one has been issued.
Before you begin
You must be a Super Admin.
Log on to the Operations Console on the Authentication Manager primary instance.
Click Deployment Configuration > RADIUS Servers.
If prompted, enter your Security Console User ID and password, and click OK.
Click the primary RADIUS server, and select Manage EAP Certificates from the context menu.
In the Manage EAP Certificates page, click the Trusted Root Certificates tab.
Click the certificate that you want to delete, and select Delete from the context menu.
When the delete process is finished, click Done.
