Question

尝试登录时此脚本存在的问题是，用户只能使用用户名字段中的用户名登录，密码字段中没有密码。他们还可以使用正确的用户名和密码登录。但是，使用正确的用户名和错误的密码时，登录失败。我搜索了一下但找不到多少。这就是我所拥有的。

<?php 
    session_start();
    include('config/db.php');
    //echo phpinfo();
    if(isset($_REQUEST['hdn_submit']) && $_REQUEST['hdn_submit']=="1"){ 

        $ldaprdn = $_POST['username'] . '@domain';
        $uname = $_POST['username'];
        $ldappass = $_POST['password'];
        //$ldapconn = ldap_connect(" old IP address",port)or die("Could not connect to LDAP server.");
        $ldapconn = ldap_connect("IP address",port)or die("Could not connect to LDAP server.");
        //echo $ldaprdn;
        if ($ldapconn)
        {
            //ldap_set_option($ldapconn,LDAP_OPT_PROTOCOL_VERSION,3) or die("Could not set ldap protocol version");
            // binding to ldap server
            $ldapbind = @ldap_bind($ldapconn,$ldaprdn,$ldappass);
            // verify binding
            if ($ldapbind)
            {
                //login successfull 
                $_SESSION['checkin'] = date('d/m/Y h:i:s A');
                $_SESSION['user_name'] = $_REQUEST['username'];

                header('Location: index.php');

            }
            else
            {
                //echo 'hello';
                echo '<script language="javascript">alert("Invalid Login. Please try again!")</script>;';
                $_SESSION['LoggedIn'] = '0';

            }

        }

    }

Answer 1

当他们在没有密码的情况下“登录”时，后端目录服务器极有可能惹恼anonymously会话。

如果在目录服务器上禁用了匿名绑定，则应该会出现故障。
