NET_LDAP2

[dbillmark]

Hello,
I'm wondering if anyone has tried using a NET_LDAP2 package filter to filter by 'memberOf.'
I'm querying AD for 'real' people and while using a filter to make sure that both a 'sn' and 'givenName' are present works for me, I'd like some added insurance that my result set contains only real people by making sure they are members of the group 'people.'
Currently I'm using this:
$filter_sn = Net_LDAP2_Filter::create('sn', 'any');
$filter_givenName = Net_LDAP2_Filter::create('givenName', 'any');
$filter = Net_LDAP2_Filter::combine('and', array($filter_sn,$filter_givenName));
But because 'memberOf' returns an array, I'm not sure how to go about adding that filter.
Any ideas would be appreciated.
Thanks in advance

I'd still be curious to know if anyone finds a way to create this filter, but I was able to create a work around in the meantime.
After querying with a filter for 'sn' and 'givenName' I then just obtained 'memberOf' in my result set and looped the array looking for my group name string.

Thanks.
