1. LDAP_OPT_NETWORK_TIMEOUT undefined

root@300d0c415acd:/# echo '<?php var_dump(LDAP_OPT_NETWORK_TIMEOUT);' | hhvm --php

Notice: Use of undefined constant LDAP_OPT_NETWORK_TIMEOUT - assumed 'LDAP_OPT_NETWORK_TIMEOUT' in /tmp/php-wrap-lzBRdU on line 1

2. ldap_get_entries don't lower attribute name as expected

$dn = 'dc=example,dc=com';
$filter = '(&(objectClass=user)(!(userAccountControl:1.2.840.113556.1.4.803:=2)))';
$attr = array('userPrincipalName');
$conn = ldap_connect('1.2.3.4', 389) or die('Connection Error.');
ldap_set_option($conn, LDAP_OPT_PROTOCOL_VERSION, 3);
ldap_set_option($conn, LDAP_OPT_REFERRALS, 0);
$bind = ldap_bind($conn, 'ldap@example.com', 'password');
if ($bind) {
    $search = ldap_search($conn, $dn, $filter, $attr);
    if ($search) {
        $ret = ldap_get_entries($conn, $search);
        print_r($ret);
    }
}
