If certificate-based authentication is enforced through either the "Require valid certificate" or "Require valid certificate and password" field for FTPS (implicit or explicit) and HTTPS ports, ActiveTransfer validates the client certificate against the certificate revocation list (CRL) specified in mft.server.crlUrl to permit or block client access to ActiveTransfer Server.

Set the value of mft.server.crlUrl as either as a file stored in an accessible directory or a file that can be downloaded from a URL.

Example:

If this property is not set, ActiveTransfer does not perform the CRL check.
