Note:
If this parameter is set to true, ActiveTransfer Server expects the clients requesting a server connection to present a valid certificate. The certificate should match one of the certificates stored in the truststore. To store valid certificates, you must create a truststore file in the same location as the keystore file, with the name keystoreName _trust. For example, if the keystore file name is server_ks.jks, the truststore name should be server_ks.jks_trust. You should add all of the valid client certificates to this truststore.
