IMPORTANT NOTE: At
IMPORTANT NOTE: At 14:47 we want to set the authentication method to "RADIUS, None" not "None". This uses RADIUS authentication and keeps the port authenticated even if the RADIUS server is not available. Brandon Harp was kind enough to point out my misunderstanding here. Thanks Brandon!
I put together a script that can be run as a cron job on a Linux device that will generate a private key, create a CSR request, submit that request to your Windows CA, download the new certificate file and restart a service. I made it for replacing an HTTPS certificate however it should work across the board.
