Description:
------------
I have called ldap_search with the optional time limit parameter set to 0 (documented as no limit) and I get this warning and no results.  The time limit parameter is #6. 

 PHP Warning:  ldap_search(): Search: Time limit exceeded in /exports/httpd_intra/ldap_test.php

I am connecting to an active directory tree.  When I first started working on the search limit on Active Directory was timing out and I was getting only a sub set of the results.  Since I had the search limit incresed I have started to get this warning.  My work arround is to set the timeout to a very long time and all of the results are returned.  But if time limit is set to 0 about half the times i get the warning and no results returned.  



Reproduce code:
---------------
ini_set('max_execution_time',20000);

$conn =  ldap_connect ("ldap://$url:3268");


$filter = '(ObjectClass=*)';
$base_dn = 'DC=foo,DC=bar';

echo "<BR>ldap bind: ". (ldap_bind($conn,$user_dn,$pass) ? ' goooooooood':'bad'

$sr   = ldap_search($conn, $base_dn,$filter,array(),0,0,0);   

$info = ldap_get_entries($conn, $sr);

print_r($info);


Expected result:
----------------
to see gooooooooood printed at the top of the page and then the text of 53000 entries.  

Actual result:
--------------
<BR>ldap bind:  goooooooood
