Bug #60787 [Fbk]: Windows Authentication + PHP = 500 errors since PHP 5.3.7

Edit report at https://bugs.php.net/bug.php?id=60787&edit=1 ID: 60787 Updated by: pajoye@php.net Reported by: test1 at breakin dot in Summary: Windows Authentication + PHP = 500 errors since PHP 5.3.7 Status: Feedback Type: Bug Package: IIS related Operating System: Windows Server 2008 R2 Enterpris PHP Version: 5.3.9 Block user comment: N Private report: N New Comment: I have no idea about supercache or WP in general (well, to actually know what you are referring to). But what's your configuration? Do you use impersonation? run php as a given user? Previous Comments: ------------------------------------------------------------------------ [2012-01-18 22:34:42] test1 at breakin dot in Alas, I don't have a specific script; the error I am seeing occurs within a particular setup on WordPress + some plugins. The bug clearly presents itself when rolling to PHP 5.3.7 or newer, and disappears when rolling back to PHP 5.3.0 - 5.3.6. However, I don't have a simple test case; it requires WordPress + plugins (such as WP Super Cache) as described in the original report. ------------------------------------------------------------------------ [2012-01-18 17:08:38] pajoye@php.net 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. ------------------------------------------------------------------------ [2012-01-18 10:44:15] test1 at breakin dot in Description: ------------ On a server where everything was working as expected with PHP 5.3.6, I upgraded PHP to 5.3.9 (latest official release, non-thread-safe). I run WordPress on IIS 7.5 / Windows Server 2008 R2. All versions of PHP after 5.3.7 are exhibiting problems with some WordPress plugins, where 500 errors are thrown and no PHP log is generated, when using Windows Authentication to protect sites (anonymous authentication disabled). If I roll back to PHP 5.3.6 or earlier, the problems resolve. If I turn off Windows Authentication while using PHP 5.3.7 or newer, the sites and plugins work as expected. The problem is the specific combination of Windows Authentication, some WordPress plugins, and PHP 5.3.7 or newer. An example plugin problem: I get 500 errors when using WP Super Cache with WordPress on PHP 5.3.7 or newer. If I roll PHP back to 5.3.6, the plugin again works as expected. Test script: --------------- http://wordpress.org/extend/plugins/wp-super-cache/ Expected result: ---------------- I expect the WordPress plugin to work as designed. Actual result: -------------- I receive a 500 error when using the WordPress plugin on a site with Windows Authentication running PHP 5.3.7 or newer. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=60787&edit=1
