I got the script to run by just hacking in the line:

ini_set("include_path", ".:/srv/www/vhosts/horde/pear/php");

But now it fails with :

PHP Fatal error:  Uncaught exception 'Horde_Prefs_Exception' with
message 'This driver needs to be refactored to use Horde_Ldap.'
in /srv/www/vhosts/horde/pear/php/Horde/Prefs/Storage/Ldap.php:67
Stack trace:
#0 /srv/www/vhosts/horde/pear/horde-prefs(83):
Horde_Prefs_Storage_Ldap->__construct('adam', Array)
#1 {main}
  thrown in /srv/www/vhosts/horde/pear/php/Horde/Prefs/Storage/Ldap.php
on line 67

Looking at that class I see:
  public function __construct($user, array $params = array())
  {
    throw new Horde_Prefs_Exception('This driver needs to be refactored
to use Horde_Ldap.');
  ...

Are LDAP preferences really not implemented in Horde 5?
