我已经在我的系统上安装了 openLDAP，后端引擎为 LDAP。安装时提供的详细信息是：Port-389,IPaddress-"192.168.....", password-"secret" ,username-bindDN-"cn=name,cn=users,dc=mydomain,dc=com"

我正在尝试创建从 android 模拟器到安装的 LDAP 服务器的连接。我正在使用unboundIdD LDAP SDK for java。编写的代码如下：

public class MainActivity extends Activity implements OnClickListener {

//String address="ldap://server1.mydomain.com";
String address="192.168.....";
int port=389;
String bindDN="CN=name,CN=users,DC=mydomain,DC=com";
String password="secret";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Button bt_login=(Button)findViewById(R.id.bt_login);
    bt_login.setOnClickListener(this);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
}

@Override
public void onClick(View arg0) {

       try {
        LDAPConnection c = new LDAPConnection(address,port,bindDN,password);

    } catch (LDAPException e) {

        e.printStackTrace();
    } 


}

}

但是在模拟器上运行此代码..按下登录按钮后..我得到一个异常。我的错误日志如下：

12-09 19:57:58.968: W/System.err(392): LDAPException(resultCode=52 (unavailable), errorMessage='Proxy operation retry failed', diagnosticMessage='Proxy operation retry failed') 12-09 19:57:58.972: W/System.err(392): at com.unboundid.ldap.sdk.LDAPConnection.bind(LDAPConnection.java:1837) 12-09 19:57:58.972: W/System.err(392): at com.unboundid.ldap.sdk.LDAPConnection.<init>(LDAPConnection.java:637) 12-09 19:57:58.972: W/System.err(392): at com.unboundid.ldap.sdk.LDAPConnection.<init>(LDAPConnection.java:534) 12-09 19:57:58.972: W/System.err(392): at gemini.ldapdemo2.MainActivity.onClick(MainActivity.java:41) 12-09 19:57:58.972: W/System.err(392): at android.view.View.performClick(View.java:2408) 12-09 19:57:58.972: W/System.err(392): at android.view.View$PerformClick.run(View.java:8816) 12-09 19:57:58.972: W/System.err(392): at android.os.Handler.handleCallback(Handler.java:587) 12-09 19:57:58.972: W/System.err(392): at android.os.Handler.dispatchMessage(Handler.java:92) 12-09 19:57:58.972: W/System.err(392): at android.os.Looper.loop(Looper.java:123) 12-09 19:57:58.972: W/System.err(392): at android.app.ActivityThread.main(ActivityThread.java:4627) 12-09 19:57:58.972: W/System.err(392): at java.lang.reflect.Method.invokeNative(Native Method) 12-09 19:57:58.972: W/System.err(392): at java.lang.reflect.Method.invoke(Method.java:521) 12-09 19:57:58.972: W/System.err(392): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:868) 12-09 19:57:58.972: W/System.err(392): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:626) 12-09 19:57:58.972: W/System.err(392): at dalvik.system.NativeStart.main(Native Method)

为什么我得到这个例外。请帮助我。我是一个新人。谢谢
