Description:
------------
I had installed PHP 4.3.10.
When I upgraded for PHP 4.4, the function ldap_parse_reference not worked. The third parameter (array &referral) not works. 

Reproduce code:
---------------
function get_ldap_referrals($ds, $dn, $filter) {			
                    ldap_set_option($ds, LDAP_OPT_REFERRALS, 0);
                    ldap_set_option($ds,LDAP_OPT_PROTOCOL_VERSION,3);
			
		    if ($ds) {
		       ldap_bind($ds);
			$sr=ldap_list($ds,$dn, $filter);		    
			$ref = ldap_first_reference($ds, $sr);
			$array_referral = array();
			$referrals =  array();
			$idx = 0;
			while ($ref) {   	 	
			      if (ldap_parse_reference($ds, $ref,&$referrals))      {
				 while ($referral = array_shift($referrals))	
					$array_referral[$idx++] = $referral ;		 	
			      }
			      $ref = ldap_next_reference($ds, $ref);
		        }
			return $array_referral;
		     }
		     else 
		       return false;
}

Expected result:
----------------
My function return all referrals from ldap server.
