[horde] authentification

[Peter Mueller]

hello

i added an application to horde, there will create a pdf-file. now, with the 
authentification-test from horde the file to create pdf don't functioned, 
because we can't send any thing to headers before.

authentication-test with horde:

define('IMP_BASE', dirname(__FILE__));
 require_once IMP_BASE . '/lib/base.php';

if (!Auth::getAuth()) {
    header('Location: ' . Horde::applicationUrl('login.php'), true);
    exit;
}


can we test in another way, if the user are login?

thanks in advance
peter
