WordPress MU

Hi,
I have the latest version of Wordpress MU installed with no plug-ins. It is configured to support subdirectories, not subdomains and is running on Lighttpd/mySQL (not my choice there).

The admin account can log in and works perfectly, but all of the users experience a redirect loop in wp-admin. I've tried changing all the salt values to kill cookies, killing cookies manually, and altering my wp-config with these values.
define('ADMIN_COOKIE_PATH', '/');
define('COOKIE_DOMAIN', '');
define('COOKIEPATH', '');
define('SITECOOKIEPATH', '');

I've also grepped around in the wp-admin directory, but didn't see anything that looked like it would cause this. Has anyone else experienced this? Does anyone know what's causing it and how to solve it? I appreciate your help!

thanks!

What is there is your error log?

Did you found a solution for that?

fix:

add following code to wp-login.php right after

//
// Main
//

if (strpos($_SERVER['SERVER_SOFTWARE'], 'lighttpd') !== false)
{
$_lighty_url = $base_url.$_SERVER['REQUEST_URI'];
$_lighty_url = @parse_url($_lighty_url);
$_SERVER['QUERY_STRING'] = $_lighty_url['query'];
parse_str($_lighty_url['query'], $_lighty_query);
foreach ($_lighty_query as $key => $val)
$_GET[$key] = $_REQUEST[$key] = $val;
}

problem goes away
