Operating system: Windows 2000 SP4
PHP version: 5.1.2
PHP Bug Type: LDAP related
Bug description: ldap_search Causes Access Violation
Description:
------------
When attempting to search a Windows 2000 Active Directory via LDAP, PHP
will crash with an Access Violation. This will only occur during certain
(reproducible) LDAP queries. For example:
Works:
$s =
ldap_search($conn,"DC=u,DC=contoso,DC=com","(&(objectCategory=group)(name=group.name.domain))",array("cn","samaccountname"));
Doesn't Work:
$s =
ldap_search($conn,"DC=u,DC=contoso,DC=com","(&(objectCategory=group)(name=group.name.domain2))",array("cn","samaccountname"));
Where the only difference is in the filter.
Server: IIS 5.1 on Windows 2000 with PHP 5.1.2. Attempted 5.1.3 (latest
snapshot) and issue still occurs.
Reproduce code:
---------------
<?
$conn = ldap_connect("rootdc.contoso.com");
ldap_set_option($conn, LDAP_OPT_PROTOCOL_VERSION, 3);
$bind = ldap_bind($conn, "[EMAIL PROTECTED]", "paSSw0rd");
$filter = "(&(objectCategory=group)(name=group.name.domain2))";
$fields =
array("member","cn","description","distinguishedname","objectcategory","samaccountname","canonicalname");
$search = ldap_search($conn,"DC=u,DC=contoso,DC=com",$filter,$fields);
$entries = ldap_get_entries($conn, $search);
var_dump($entries);
?>
Expected result:
----------------
Expected to return fields listed in the $fields array in the $entries
array.
Actual result:
--------------
The page load terminates and reports: "PHP has encountered an Access
Violation at 01CE5CE6"
Backtrace (NOTE: php.exe used for debugging. Normally use IIS5.1
