OpenFire IM Server LDAP config for SBS2003 AD

I need to correctly configure LDAP for using OpenFire (IM server) on a Windows SBS2003 server.  I have the LDAP configured to the point where I can see the user templates, but I cannot figure out how to change the LDAP config to see actual domain users.  The config I am using was designed for Server 2003, not SBS2003, so the AD tree for Server 2003 is somewhat different.  What do I need to change in the following to get this to work properly?

Current LDAP config (from openfire.xml)
<ldap>

    <port>389</port>  
    <baseDN>cn=SBSUsers, cn=Users,cn=MyBusiness,dc=RushTechnologiesInc,dc=local</baseDN>

    <adminPassword>calista</adminPassword>

    <sslEnabled>false</sslEnabled>
