Answer 1

我知道这是一个相当老的问题，如果您仍然需要答案，那么如果您在单个 php 文件中运行此代码会发生什么？

$username = 'hello';
$password = '123123';
$server = '192.168.32.4';
$domain = '@yourdomain.local';
$port = 389;

$connection = ldap_connect($server, $port);
if (!$connection) {
    exit('Connection failed');
}

// Help talking to AD
ldap_set_option($connection , LDAP_OPT_PROTOCOL_VERSION, 3);
ldap_set_option($connection , LDAP_OPT_REFERRALS, 0);

$bind = @ldap_bind($connection, $username.$domain, $password);
if (!$bind) {
    exit('Binding failed');
}

// This is where you can do your work
echo 'Hello from LDAP';

ldap_close($connection );

Answer 2

我使用了这些函数：

function authenticate($username, $password){
    include 'conf/config.inc.php';

    $ldap_Userdn = getUserDN($username);

    if($ldap_Userdn!=""){
        $ldap_con = ldap_connect($ldap_hostname,$ldap_port);
        ldap_set_option($ldap_con, LDAP_OPT_PROTOCOL_VERSION, 3);

        if(ldap_bind($ldap_con, $ldap_Userdn, $password)){
            return true; 
        } else  {
            //echo "<br>Error bind checkPassword function<br>";
            return false;
        }
    } else {
        echo "Error to find user DN" . ldap_error($ldap_con);
    }

    ldap_close($ldap_con);
}

function getUserDN($username){
    include 'conf/config.inc.php';

    $data = "";

    $ldap_con = ldap_connect($ldap_hostname,$ldap_port);
    ldap_set_option($ldap_con, LDAP_OPT_PROTOCOL_VERSION, 3);
    ldap_set_option($ldap_con, LDAP_OPT_REFERRALS, 0);

    if(ldap_bind($ldap_con, $ldap_dn, $ldap_password)){
        $filter="(cn=$username)";
        $dn=$ldap_search; //even if it seems obvious I note here that the dn is just an example, you'll have to provide an OU and DC of your own

        $res = ldap_search($ldap_con, $ldap_search, $filter);
        $first = ldap_first_entry($ldap_con, $res);
        $data = ldap_get_dn($ldap_con, $first);

    } else {
        echo "<br>Error bind getUserDN function<br>" . ldap_error($ldap_con);
    }

    ldap_close($ldap_con);
    return $data;
}

这是我的 config.inc.php：

<?php
$ldap_hostname = "my openldap IP";
$ldap_port = "389";
$ldap_dn = "cn=Manager,dc=mydomain,dc=com";
$ldap_search = "dc=mydomain,dc=com";
$ldap_password ="my password";
?>

Answer 3

检查您的登录和密码是否正确。
并在登录之前添加域。请参阅示例底部（总部\登录）：

<?php
$login = 'HQ\student';
$password = 'MYPASS';
        
$ldap_link = ldap_connect('pdc.bc') or die("Sorry, could not connect to LDAP server.");

$ldapbind = @ldap_bind($ldap_link, $login, $password) or die ("Error trying to bind: ".ldap_error($ldap_link));
?>
