Kaltura - Renewing Your KMS SSL Certificate

You may receive a notice that a certificate for your campus' MediaSpace will be expiring soon. This document outlines the steps required to get that certificate renewed.

NOTE: This document is expressly intended for campus Kaltura Administrators.

If your campus Kaltura instance uses a custom domain rather than the default kaltura.com domain, you will need to periodically renew the SSL certificate hosted by Kaltura for your domain. This document gives an overview of the process that unfolds once renewal is necessary.

The certificate renewal process begins with the receipt of a notice that the certification on your MediaSpace instance will be expiring soon. This message can originate from Kaltura support, from your campus security office, or your certificate authority. It is good practice to be aware of the date of expiration even without these reminders, because reminders are generally sent to the email address of the person who requested the original certificate and that person may not be the same as the current administrator.
