Use the certificate revocation list
x509-use-crl specifies that the server instance uses the certificate
revocation list (CRL). By default, instances do not use any CRLs. In this case, the CRLs
in the certificate authority store are ignored.
x509-use-crl is added, the CRLs are loaded
and participate in the client certificate verification. If the CRL
has expired, the SSL handshake is rejected.
The instance uses certificate revocation list when authenticating clients.
