"NOTE: If your Active Directory implementation contains subdomains, you will not be able to query for users in a sub domain using the base DN of the root domain. However, when using Active Directory, you may also query LDAP against the Global Catalog (GC) Server on TCP port 3268. The GC contains partial information for *all* objects in the Active Directory forest and provides referrals to the subdomain in question when further information is required. If you cannot "find" users in your subdomains, leave the base DN at the root and change to the GC port." - from the KB
