property RequestDNList: TScDistinguishedNameList;
Specifies a list of Distinguished Names (DN) that the server expects in the issuer field of the client certificate. The server sends RequestDNList to the client in the certificate request.
You can use the IsClientCertificateRequired property to specify whether the client certificate is required to establish a TLS session. When IsClientCertificateRequired is set to False, RequestDNList has no effect.
