I don't know what "HTTP authentification" is. In config/horde.php I can 
see these authentification types:

// What backend should we use for authenticating users to Horde? Valid
// options are currently 'imap', 'ldap', 'mcal', 'sql', and 'ftp'.
$conf['auth']['driver'] = '';

doesn't mention http.

In my case it is empty because I have set in config/registry.php:
$this->registry['auth']['login'] = 'imp';
$this->registry['auth']['logout'] = 'imp';

So, what do you mean by "HTTP authentication"?
