Missed predefined variables in HTTP Authentification

I'm facing somet开发者_如何学Gohing weird, after move one of my application to different server/host provider(from centOS to Ubuntu Server). So basicly, i have simple http authentification as auth module in that app. It uses predefined value, in environment variables, which is : $_SERVER['PHP_AUTH_USER'] and $_SERVER['PHP_AUTH_PW']. As you can see on my title, for somehow reason, these predefined value which i used in my auth module, is missing!

I check my environment setting, in my php.ini, since by these link : http://www.php.net/manual/en/features.safe-mode.functions.php mention that In safe mode, the variables PHP_AUTH_USER, PHP_AUTH_PW, and AUTH_TYPE are not available. I try set it on/off without different result. And REMOTE_USER var is not available too in my case.

Someone ever face something like these? Any suggestion?

Anyway, thanks.
