By Design certificates have an expiration date, when a certificate is approaching its expiration date, it is necessary to renew it to not lose access to the resources the certificate was used to authenticate to.
If a certificate is created in one of the locations that EZCA supports auto rotation, the certificate can be set to be auto renewed automatically by EZCA. If the certificate is set for auto renewal, EZCA will take care of the renewal automatically and will email the domain owners when the certificate is renewed.
If the certificate is created and maintained in a Key Management System that EZCA supports auto rotation of certificates but it is not set for auto renewal, an approved requester of the domains contained in that certificate will have to do the following steps:
If a certificate was created and stored in a location that is not managed by EZCA (For Example: a CSR was imported or a Certificate was created on the browser) an approved requester of the domains contained in that certificate will have to do the following steps:
