Once the CA's certificate is in place, we are able to issue new certificates with it.
In order to do so, we fill the form which appears on the top of the module's page. The mandatory data are the certificate's common name and the number of days until its expiration. This last value is limited by the duration of the CA's certificate.
When the certificate has been issued, it will appear in the certificate's list and it will be available to the remainder eBox modules to use it.
