Is there anyway to reset the community address book?

I changed the ldap filter to only have users in a test group for
conferencing. but prior to that on my client, I did a Fetch contacts,
and it grabbed alot of users that aren't part of our test group.
Nothing I've done so far as removed that list from my system.

tried:
running ldap-sync.sh
uninstalling client
uninstalling client and removing the meeting folder in documents and
settings/.../application data
restarting the server
turned off retrieve community address book in client, turned it back on


do I need to get into the database to fix it? I'm not familiar with
postgres, somewhat familiar with mysql.
