Description:
------------
I have a script which is using the nice new SPL RecursiveDirectoryIterator.

The iterator is being asked to look at files which reside on another computer which is accessed via a drive mapping.

In terms of permissions, I have full access to the mapping.

The webserver is running with my credentials. I am using Sambar Server with php V5.0.4 ISAPI.

The script below gives a different response when using CLI and web (See results below).

I do have 2 different php.ini files - php-cli.ini and php-isapi.ini

The only difference between them is html_errors is On for the ISAPI version and Off for the CLI version and the phpmanual is NOT shown for the CLI version.

I've tried using the full UNC path to the directory and this works in both CLI and ISPAI mode. The line below works in both CLI and ISAPI modes.

$objRDI = new RecursiveIteratorIterator(new filterAutomatedEarnieIQBackup(new RecursiveDirectoryIterator("\\\\BANDACCESS\\IQ Backup")));


Reproduce code:
---------------
<?php
abstract class RecursiveFilterIterator extends FilterIterator implements RecursiveIterator
	{
	private $ref;

	function __construct(RecursiveIterator $it)
		{
		$this->ref = new ReflectionClass($this);
		parent::__construct($it);
		}

	function hasChildren()
		{
		return $this->getInnerIterator()->hasChildren();
		}

	function getChildren()
		{
		return $this->ref->newInstance($this->getInnerIterator()->getChildren());
		}
	}

class filterAutomatedEarnieIQBackup extends RecursiveFilterIterator
	{
	function accept()
		{
		return $this->getInnerIterator()->isFile() && (strpos($this->getInnerIterator()->getFilename(), 'AutomatedEarnieIQBackup') !== False);
		}
	}

$objRDI = new RecursiveIteratorIterator(new filterAutomatedEarnieIQBackup(new RecursiveDirectoryIterator("K:\\IQ Backup")));
foreach($objRDI as $sPath => $sFile)
	{
	echo number_format(filesize($sPath)) . " {$sPath}<br />\n";
	}
?>

Expected result:
----------------
249,648,640 K:/IQ Backup/AutomatedEarnieIQBackup20050728101148<br />


Actual result:
--------------
