Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

if ($_POST["submit"])
{
include ('includes/conn_ldap.php');

     $info["uid"]                       = $_POST['uid'];
     $info["userPassword"]              = $_POST['userPassword'];
	 $info["cn"]                        = $_POST['cn'];
     $info["sn"]                        = $_POST['sn'];
     $info["mail"]                      = $_POST['mail'];
     $info["objectClass"]               = "inetOrgPerson";
     $dn                                = "uid=" . $_POST['uid'] . ",dc=localhost";

$result = ldap_add($conn, $dn, $info);
}
