Basic authentication
From ULYSSIS documentation
Because in our webserversetup PHP is installed as a common gateway interface (CGI) basic authentication will not work in its usual way. There is however a workaround. First add a .htaccess file with following code in it: <IfModule mod_rewrite.c> RewriteEngine on \n RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L] </IfModule>
Next add the following line to your script right before the authentication: list($_SERVER['PHP_AUTH_USER'], $_SERVER['PHP_AUTH_PW']) = explode(':' , base64_decode(substr($_SERVER['HTTP_AUTHORIZATION'], 6)));
Now your script should work with basic authentication.
