authentication with php under fastcgi

Hi,

When using php under fastcgi REMOTE_USER isn't defined.  It
is necessary
to use REDIRECT_REMOTE_USER.

So the setUsername function in auth.php should look
something like this:

        function setUsername($username)
        {
                if ($username == "") // Use the
current user
                {
                        if ($_SERVER["REMOTE_USER"]) {
                                $this->user = $_SERVER["REMOTE_USER"];
                        } elseif ($_SERVER["REDIRECT_REMOTE_USER"]) {
                                $this->user = $_SERVER["REDIRECT_REMOTE_USER"];
                        }

                }
                else
                {
                        $this->user = $username;
                }
        }
