使用未绑定ID更改“活动目录”中的帐户到期日期？

我正在尝试更改account expiration dateWindows中的窗口active directory。

我可以使用以下代码更改帐户有效期中的从不选项。

final Modification mod = new Modification(ModificationType.REPLACE,
        "accountExpires", "9223372036854775807");//Can change the required date with milliseconds

LDAPResult result=connection.modify(userDN, mod);

但是，如果我尝试更改account expiry date方法，则代码将成功执行，并且成功将打印在控制台中。但日期不会在中更改AD。

这是我更改或延长帐户有效期的代码。

公共类AccountExpireSetting {

public void ChangeAccountExpires(String userDN,String password , String dateToChange) throws LDAPException
{
    LDAPConnection connection=null;
    String someDate = null;
    try {
        connection = new LDAPConnectionObject().getConnection();
    } catch (LDAPException e1) {
        e1.printStackTrace();
    }


    try{
        SimpleDateFormat sdf = new SimpleDateFormat("dd.MM.yyyy");
        Date date = sdf.parse(dateToChange);
        System.out.println("Date to MillSeconds : "+date.getTime());
        someDate = String.valueOf(date.getTime());

        Date date1=new Date(date.getTime());
        System.out.println("MillSeconds to Date : "+date1);
    }
    catch(Exception e){
        e.printStackTrace();
    }

    try{

        System.out.println("Going to replace account expires to never");
        final Modification mod = new Modification(ModificationType.REPLACE,
                "accountExpires", someDate);// 9223372036854775807 milliseconds can change the password to never expire
        // 9223372036854775807  

        LDAPResult result=connection.modify(userDN, mod);
        System.out.println("Account expires status : " + result); // Password status : LDAPResult(resultCode=0 (success), messageID=2, opType='modify')
    }catch(LDAPException e) {
        // TODO Auto-generated catch block
        System.out.println("Error in replacing account expires to never");  

        e.printStackTrace();
    }finally
    {
        System.out.println("Closing the connection.");
        connection.close();
    }  
}
public static void main(String[] args) {
    // TODO Auto-generated method stub
    String temp="CN=Anand,OU=Java,OU=Chennai,OU=Department,dc=tstdmn,dc=com";
    try {
        new AccountExpireSetting().ChangeAccountExpires(temp, "password@123","08.06.2014");
    } catch (LDAPException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}

}

希望大家能给出更好的解决方案。
