【问题描述】:
从以下网站,我找到了执行 java AD 身份验证的代码。
http://java2db.com/jndi-ldap-programming/solution-to-sslhandshakeexception
以下是代码:
MySSLSocketFactory.java
import java.io.IOException;
import java.net.InetAddress;
import java.net.Socket;
import java.net.UnknownHostException;
import java.security.SecureRandom;
import javax.net.SocketFactory;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSocketFactory;
import javax.net.ssl.TrustManager;
public class MySSLSocketFactory extends SSLSocketFactory {
private SSLSocketFactory socketFactory;
public MySSLSocketFactory() {
try {
SSLContext ctx = SSLContext.getInstance("TLS");
ctx.init(null, new TrustManager[]{new DummyTrustmanager()}, new SecureRandom());
socketFactory = ctx.getSocketFactory();
} catch (Exception ex) {
ex.printStackTrace(System.err);
}
}
public static SocketFactory getDefault() {
return new MySSLSocketFactory();
}
@Override
public String[] getDefaultCipherSuites() {
return socketFactory.getDefaultCipherSuites();
}
@Override
public String[] getSupportedCipherSuites() {
return socketFactory.getSupportedCipherSuites();
}
@Override
public Socket createSocket(Socket socket, String string, int num, boolean bool) throws IOException {
return socketFactory.createSocket(socket, string, num, bool);
}
@Override
public Socket createSocket(String string, int num) throws IOException, UnknownHostException {
return socketFactory.createSocket(string, num);
}
@Override
public Socket createSocket(String string, int num, InetAddress netAdd, int i)
throws IOException, UnknownHostException {
return socketFactory.createSocket(string, num, netAdd, i);
}
@Override
public Socket createSocket(InetAddress netAdd, int num) throws IOException {
return socketFactory.createSocket(netAdd, num);
}
@Override
public Socket createSocket(InetAddress netAdd1, int num, InetAddress netAdd2, int i) throws IOException {
return socketFactory.createSocket(netAdd1, num, netAdd2, i);
}
}
DummyTrustmanager.java
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import javax.net.ssl.X509TrustManager;
public class DummyTrustmanager implements X509TrustManager {
public void checkClientTrusted(X509Certificate[] cert, String string) throws CertificateException
{
}
public void checkServerTrusted(X509Certificate[] cert, String string) throws CertificateException
{
}
public X509Certificate[] getAcceptedIssuers()
{
return new java.security.cert.X509Certificate[0];
}
}
TestAD.java
import java.util.Hashtable;
import javax.naming.Context;
import javax.naming.directory.DirContext;
import javax.naming.directory.InitialDirContext;
public class TestAD {
public static void main(String[] args) {
try {
//String url = "ldaps://abc.company.com:636";
String url = "ldaps://xyz.group.com:636";
String conntype = "simple";
// String id = "abc@abc.company.com";
String id = "xyz.group.com";
//String password = "abcpassword";
String password = "xyzpassword";
Hashtable<String, String> environment = new Hashtable<String, String>();
environment.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
environment.put(Context.PROVIDER_URL, url);
environment.put("java.naming.ldap.factory.socket", "MySSLSocketFactory");
environment.put(Context.SECURITY_AUTHENTICATION, conntype);
environment.put(Context.SECURITY_PRINCIPAL, id);
environment.put(Context.SECURITY_CREDENTIALS, password);
DirContext ldapContext = new InitialDirContext(environment);
System.out.println("Bind successful");
} catch (Exception exception) {
exception.printStackTrace();
}
}
}
我的公司有几个子公司,他们有自己的 LDAP。当我针对我公司 ABC 的 LDAP 运行 TestAD 时,它运行良好。但是当我针对子公司 XYZ 的 LDAP 运行它时,我得到了以下异常:

失败的原因可能是什么?我没有将 ABC 或 XYZ 的证书导入我的信任库。为什么它适用于 ABC 但不适用于 XYZ?会不会是 XYZ 期待我的证书?
【问题讨论】:
-
补充一下,我可以远程登录到 xyz.group.com 636,所以连接不是问题。
-
从“
java.security.cert.CertificateException: No subject alternative DNS name matching xyz.group.com found”异常中反映的情况来看,您的应用程序中使用的证书中不存在 DNS“xyz.group.com”的主题备用名称。请确保您使用的是其他 AD 环境信任的证书进行通信。 -
您的意思是“一个 LDAP server 失败,但另一个 LDAP server 通过了”? LDAP 是一个协议,而不是一个东西。
-
@user207421 大声笑.. 希望协议是正确的? ;) 在这里(再次)感谢您的贡献(居高临下的态度)。
