HTTP Authentication with safe_mode

Hi, When safe_mode is on, $PHP_AUTH_* (if globals are on) and $_SERVER[PHP_AUTH*]. The only other thing I find about this in the docs is this (in several places): ---- Note: If safe mode is enabled, the uid of the script is added to the realm part of the WWW-Authenticate header. ---- So, how can I do an HTTP Authentication using PHP (with no external authentication). Actually, how can I access the username and password in php? I thing that might be some other way. Nowhere in the docs or googling, I found something stating that it is not possible to do http authentication with safe_mode on. In the case it isn't possible to do such thing. Does anyone miss this feature? Regards, Raul Dias
