Hi there. Just saw your post about LDAP against 2 AD's. Shouldn't be a problem. We are a Novell shop and LDAP against 2 NDS trees. In LDAP configuration, specify the separate contexts to search separated by a ";" as shown in the example. The ability is there for the subcontext search, but we often search specific containers of objects so our search list is quite lenghty. The response time is very quick.
