使用PHP从LDAP验证用户

$ldap_server = "ldap.example.com";
$ldap_user = "cn=admin,dc=example,dc=com";
$ldap_password = "password";
$ldap_dn = "dc=example,dc=com";

// Connect to LDAP server
$ldap_conn = ldap_connect($ldap_server) or die("Could not connect to LDAP server.");

// Bind to LDAP server
ldap_set_option($ldap_conn, LDAP_OPT_PROTOCOL_VERSION, 3);
ldap_set_option($ldap_conn, LDAP_OPT_REFERRALS, 0);
$bind = ldap_bind($ldap_conn, $ldap_user, $ldap_password);

// Search for user
$filter = "(uid=".$_POST['username'].")";
$result = ldap_search($ldap_conn, $ldap_dn, $filter);
$entries = ldap_get_entries($ldap_conn, $result);

// Check if user exists and password is correct
if ($entries['count'] == 1 && @ldap_bind($ldap_conn, $entries[0]['dn'], $_POST['password'])) {
    // User authenticated
} else {
    // Authentication failed
}
