PHP_AUTH_PW is being improperly set when external authentication is active
on Apache.

I have a directory structure that is protected via Apache authentication, according
to the PHP documentation the PHP_AUTH_PW should not be available when
external authentication is in use.  This is necessary for security concerns when you
cannot trust the php applications.  In any case, w/ php the AUTH_PW is being
set at all times.  Please fix, thanks!

This bug has been fixed in CVS. You can grab a snapshot of the
CVS version at http://snaps.php.net/. In case this was a documentation 
problem, the fix will show up soon at http://www.php.net/manual/.
In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites.
Thank you for the report, and for helping us make PHP better.
