That is the work around that I have been using and is is very icky.

What aboutthe equivalent of line +- 305 in turba/lib/ldap.php
$attributes = array_filter($attributes, array($this, 'cleanEmptyAttributes'));
    function cleanEmptyAttributes($var)
    {
        if (!is_array($var)) {
            return ($var != '');
        } else {
            foreach ($var as $v) {
                return($v != '');
            }
        }
    }

while building the dirtyPrefs array arround line 285 in 
horde/lib/Prefs/ldap.php.  I was looking at that yesterday and feel like
it would work just by not including the prefs leaving the ldap directory
as before with no value, which is what I think we are after.  AFAIK,
this is why turba and erase attributes.

I tried applying it last night and wasn't successful.  I did it quickly and
probably did something dumb.  I didn't write down the message because I 
meant to try again tonight.

Thanks,
