在ssl（ldaps）的支持下连接活动目录

Posted 2021-03-28

我试图在ssl的支持下与活动目录连接。

我尝试了以下网站的步骤。

http://confluence.atlassian.com/display/CROWD/Configuring+an+SSL+Certificate+for+Microsoft+Active+Directory

当我尝试从java代码连接活动目录时，它会出现以下错误。

正在使用的代码是

import java.util.Hashtable;
import javax.naming.*;
import javax.naming.directory.*;

public class ConnectActiveDirectory {

    public static void main(String[] args) throws NamingException {
        Hashtable env = new Hashtable();
        env.put(Context.SECURITY_AUTHENTICATION, "simple");
        env.put(Context.SECURITY_PRINCIPAL,"[e-mail]");
        env.put(Context.SECURITY_CREDENTIALS, "password");
        env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory");
        env.put(Context.PROVIDER_URL, "ldaps://172.16.12.4:636/cn=Users,dc=mysite,dc=com");
        try{
            java.io.InputStream in = new java.io.FileInputStream("C:\client.crt");
            java.security.cert.Certificate c = java.security.cert.CertificateFactory.getInstance("X.509").generateCertificate(in);
            java.security.KeyStore ks = java.security.KeyStore.getInstance("JKS");
            ks.load(null);
            if (!ks.containsAlias("alias ldap")) {
                ks.setCertificateEntry("alias ldap", c);
            }
            java.io.OutputStream out = new java.io.FileOutputStream("C:\keystorefile.jks");
            char[] kspass = "changeit".toCharArray();
            ks.store(out, kspass);
            out.close();        
        }catch(Exception e){
            e.printStackTrace();
        }
        System.setProperty("javax.net.ssl.trustStore", "C:\keystorefile.jks");
        DirContext ctx = new InitialDirContext(env);
        NamingEnumeration enm = ctx.list("");
        while (enm.hasMore()) {
            System.out.println(enm.next());
        }
        ctx.close();
    }
}

我有没有做错？

我在哪里可以获得与Active Directory进行ssl连接的良好教程？

http://confluence.atlassian.com/display/CROWD/Configuring+an+SSL+Certificate+for+Microsoft+Active+Directory网站是否有正确的步骤来创建和连接活动目录与ssl？

请帮助我。

答案

我的AD域名重命名后，我遇到了类似的问题。重新安装证书服务后，您需要删除并重新颁发颁发给域控制器的证书。脚步：

1. 打开MMC
2. 添加管理单元>证书>计算机>本地计算机
3. 导航到“个人”>“证书”
4. 删除发给这台机器的所有旧证书（在我的情况下，这些是由旧CA颁发的）
5. 右键单击“证书”文件夹，单击“申请新证书”。
6. 按照步骤将新证书颁发给域控制器。
7. 重新启动（不确定是否有必要，但我在它工作之前重新启动）

另一答案

我使用Atlassian Crowd和Active Directory通过SSL获得了相同的错误消息。它不适用于这个特定问题，但当我试图找出发生了什么时，这个帖子是第一个Google搜索命中，所以我会在这里写下来。

在我的情况下，我首先测试没有SSL，然后更改为SSL。结果我忘了更改Crowd Connector设置中使用的协议。

之前：ldap：//：389之后：ldaps：//：636

无意中使用ldap：//：636给了我“连接重置”错误。
