Java 如何使用Apache LDAP客户端连接到LDAP？

我按照Apache的LDAP客户端API的用户指南连接到ApacheDS LDAPS服务器。但它无法连接。我什么都试过了。我能够连接到LDAP服务器。用户指南并没有真正的帮助，因为它们遗漏了示例中使用的一些函数。我正在使用ApacheDS生成的证书

import static org.junit.Assert.assertTrue;

import org.apache.directory.api.util.Network;
import org.apache.directory.ldap.client.api.LdapConnection;
import org.apache.directory.ldap.client.api.LdapConnectionConfig;
import org.apache.directory.ldap.client.api.LdapNetworkConnection;
import org.apache.directory.ldap.client.api.NoVerificationTrustManager;

public class SecureP2P {

public static void main(String[] args) throws Exception {

    LdapConnectionConfig sslConfig = new LdapConnectionConfig();
    sslConfig.setLdapHost(Network.LOOPBACK_HOSTNAME);
    sslConfig.setUseSsl(true);
    sslConfig.setLdapPort(10636);
    sslConfig.setSslProtocol("SSLv3");
    sslConfig.setTrustManagers(new NoVerificationTrustManager());

    try (LdapConnection connection = new LdapNetworkConnection(sslConfig)) {
        connection.bind("uid=admin,ou=system", "secret");

        assertTrue(((LdapNetworkConnection) connection).getConfig().isUseSsl());
        assertTrue(connection.isAuthenticated());
    }
}
}

以下是ApacheDS服务器日志文件中的错误：

运行客户端时出现错误消息：

摆脱SSLv3，或在两端使用支持它的JRE。@EJP I删除了SSLv3，但仍然无法连接。不知道你说的两端都有JRE是什么意思。
