SSL/TLS/StartTLSリスナーは、他の証明書が提供されない場合、 自己署名証明書を使用します。--tls-cipherと--tls-protoを使用して 許可する暗号を設定できます。ただし、レガシーアルゴリズムを使用するには Javaインストールのjava.security.propertiesファイルの調整が必要です。 https://www.java.com/en/configure_crypto.html を参照してください。
資格情報を傍受したり、クライアントにデータを提供したりします。
追加オプション：
--load= LDIF file with data to load
--schema= LDIF file containing schema definition
(if the server is not run --schemaless a basic default schema is applied)
