[horde] Authenticate with Horde

[Peter Mueller]

Hello

I made an application that will use the horde authentication. With Horde 2.1 
and IMP 3.1 all works well. But now with Horde 2.2.4 and IMP 3.2.2. it doesn't 
functione any more. We put the following lines in my script, but with the 
newer version of Horde and IMP it didn't recognize the authentication:

Perhaps do you know where the problem is?

With regards
Peter


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

if (!Auth::getAuth()) {
    header($hd_domain);
    exit;
}
