java - 如何使用 SSL 连接到 ApacheDS？

Question

我需要帮助使用 SSL 连接到 Apache 的目录服务器。我能够连接到 LDAP 服务器，但是当我尝试连接到 LDAPS 时，我不断收到错误消息。我在服务器配置中启用了 TSLv1.2 协议(protocol)，但仍然没有成功。我完全遵循了 Apache 的用户指南，但仍然没有运气!

这是我尝试使用 Apache 的 LDAP 客户端 API 进行连接的代码:

编辑:我添加了信任管理器。

public class SecureP2P {

public static void main(String[] args) throws LdapException, IOException, NamingException {

    LdapConnectionConfig config = new LdapConnectionConfig();
    config.setLdapHost(Network.LOOPBACK_HOSTNAME);
    config.setLdapPort(10636);
    config.setUseSsl(true);
    config.setEnabledProtocols("TLSv1.2");
    config.setSslProtocol("TLSv1.2");
    config.setTrustManagers(new NoVerificationTrustManager());

    LdapConnection connection = new LdapNetworkConnection(config);
    connection.connect();
    connection.bind("uid=admin,ou=system", "secret");
    connection.unBind();
    connection.close();
}
}

来自客户端的错误消息:

我没有从服务器收到“证书未知异常”。即使我尝试使用 Apaches Directory Studio 通过 SSL 连接到服务器，它仍然无法进行身份验证!该证书是由 apacheDS 生成的，所以我不知道是什么问题。这真是令人沮丧。

Answer 1

我能够解决这个问题。我使用 Keytool 创建了一个证书并导入到 ApacheDS 配置的 keystore 中。我能够通过 LDAPS 进行连接和身份验证。我只是不明白为什么 ApacheDS 生成的证书没有被 Apache Directory Studio 的客户端接受。
