由于显然无法在我的BlackBerry App上使用LDAP进行身份验证,因此我尝试使用某种解决方法。我想在两者之间使用Web服务,而不是直接在LDAP服务器上进行身份验证。所以它看起来像这样
App --calls--> Web Service --calls--> LDAP Server
因此,Web Service应该获取应用程序提供的用户名和密码,并将其发送到LDAP服务器。如果可以登录,则Web服务将获得TRUE作为响应并将其转发给App。
它应该如何运作。但是目前,当我从应用程序调用Web服务时,我收到以下错误:
SoapFault - faultcode: 'S:Server' faultstring: 'java.lang.NullPointerException' faultactor: 'null' detail: org.kxml2.kdom.Node@21e05a11
看起来像服务器问题,但我不知道在哪里:(
好吧,这就是我正在使用的Web服务:
import javax.ejb.Stateless;
import javax.jws.WebService;
import com.novell.ldap.LDAPConnection;
import com.novell.ldap.LDAPException;
@Stateless
@WebService()
public class ldapServiceBean implements ldapService {
@Override
public String error() {
// TODO Auto-generated method stub
return null;
}
@Override
public boolean ldapLogin(String username, String password) {
int ldapPort = LDAPConnection.DEFAULT_PORT;
int ldapVersion = LDAPConnection.LDAP_V3;
String ldapHost = "dc1.somehost ";
String loginDN =
"CN="+username+",OU=employee,OU=user,DC=somehost";
byte[] passwordBytes = password.getBytes();
LDAPConnection lc = new LDAPConnection();
try {
// connect to the server
lc.connect( ldapHost, ldapPort );
// authenticate to the server
lc.bind( ldapVersion, loginDN, passwordBytes );
System.out.println("Bind successful");
return true;
}
catch( LDAPException e ) {
if ( e.getResultCode() == LDAPException.NO_SUCH_OBJECT ) {
System.err.println( "Error: No such entry" );
} else if ( e.getResultCode() ==
LDAPException.NO_SUCH_ATTRIBUTE ) {
System.err.println( "Error: No such attribute" );
} else {
System.err.println( "Error: " + e.toString() );
}
}
return false;
}
这就是调用Web服务的方法
private static final String SOAP_ACTION = "";
private static final String METHOD_NAME = "ldapLogin";
private static final String NAMESPACE = "http://ldapproxy.somehost/";
private static final String URL = "http://myIP:8080/LDAPProxy/ldapServiceBeanService";
...
public boolean login(String username, String password) {
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
//SoapObject
request.addProperty("username", username);
request.addProperty("password", password);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
//envelope.dotNet = true;
//envelope.bodyOut = request;
envelope.setOutputSoapObject(request);
HttpTransport httpTransport = new HttpTransport(URL);
try
{
httpTransport.call(SOAP_ACTION, envelope);
System.out.println("request: " + httpTransport.requestDump);
resultsRequestSOAP = (SoapObject) envelope.getResponse();
return true;
}catch(SoapFault sF){
String error = sF.toString();
Dialog.alert(error);
}
catch (Exception aE)
{
Dialog.alert("Connection failed");
aE.printStackTrace ();
}
return false;
}
到目前为止我发现了什么: 似乎webservice没有收到用户名和密码属性。当我打印出来时,我得到:
`CN=null, OU=employee, OU=...`
就像我在这篇文章Web service recieves null parameters from application using ksoap method上看到的那样,ksoap似乎有冒号问题。我改变了我的NAMESPACE但没有任何成功。也许我也需要更改我的URL。但是,当我仍然需要使用localhost时,我该怎么做呢?
答案 0 :(得分:1)
一如既往以这种方式进行LDAP绑定测试,请回想一下,标准要求绑定用户名,无密码,是成功的匿名绑定,因此您必须在登录尝试时验证此情况(空密码)。
