I'm attempting to use the admin plugin to handle users, but have run into an interesting problem.

When I 'login', a window appears asking for my name/password.

To logout, I've created this function

function sign_out() {
    unset($_SESSION['__CurrentUser']);
    unset($this->CurrentUser);
    //$this->redirectTo(array());
}

it works, but when I login again, no window appears to prompt me for a username and password. When I do a print_r($this), I can see that my username and password are being sent in the request as PHP_AUTH_USER and PHP_AUTH_PW.

How do I unset those so I can get the username and password prompt again? (besides closing the browser window)

Ah, and I must have a short memory. Thanks anyway Kaste! I wish you merry weekend, despite posters who repeat themselves.
