Hi Team I created an Instance of FreeRadius a few months back for my organisation. I followed the user guide for setting up certificates. http://deployingradius.com/documents/configuration/certificates.html Deploying RADIUS: Production Certificates<http://deployingradius.com/documents/configuration/certificates.html> deployingradius.com Production Certificates. Once the initial EAP testing has been performed, it is time to create the real certificates to use in your production network. These certificates will be configured on the end hosts that will be doing PEAP, TTLS, or EAP-TLS authentication. It seems the Certificates have expired, which is fine for OS X and Linux devices, which install new certificates automatically next time you connect while connecting but not for Windows10 that require the certificates be installed manually. Is it possible for me to change the certificates so they last a year?
