If it knows the location of a certificate, certmonger can track the expiration date and notify you when the certificate is about to expire. If it has access to the corresponding private key and information about the CA which issued the certificate, certmonger can even attempt to automatically obtain a new certificate. Supports certificate and key storage in PEM or NSSDB formats. Can self-sign certificates, or can submit them to either certmaster or development versions of IPA.
