Bug 1012125

Cause: If a replication is configured against a sub backend instance before initializing the backend with a sub suffix entry, an RUV entry is inserted with a temporary sub suffix entryid to the entryrdn index. The temporary entryid was not updated when the real sub suffix entry was added. Consequence: Search failed to return entries under the sub suffix if a replication is configured before initializing the sub backend. Fix: When a real sub suffix is added, the temporary entry id in the entryrdn index is replaced with the real entry id. Result: Search successfully returns entries under the sub suffix if a replication is configured before initializing the sub backend.
