One solution to this is to use a referral server. There are a
few implementations but none that are easily available AFAIK.
The idea is to generate a indexed database that can look at the
search filter and figure which servers might contain the object
and give referrals to those. Have a look at Common Indexing
Protocol, RFC 2651.

2.0.7 seems to be reasonably stable (some claims it's more stable
than 1.2.11). 1.2.11 can only give referrals and not search
references which is what you want if you want some results from
one server but at the same time be refered to others.
In my opinion you should try 2.0.7.
