[389-devel] Please review: [389 Project] #47523: Set up replcation/agreement before initializing the sub suffix, the sub suffix is not found by ldapsearch

https://fedorahosted.org/389/ticket/47523 https://fedorahosted.org/389/attachment/ticket/47523/0001-Ticket-47523-Se... Bug description: If a replication is configured against a backend before initializing the backend with a suffix entry, an RUV entry is inserted first with the entryid 1. The RUV entry's entryrdn is added to the entryrdn index with a suffix entry which is a parent entry of the RUV entry having a temporary entryid 0, which was to be replaced with the real entryid when the real suffix entry is added. But the replacement code was not executed. Fix description: When a real suffix is added to the entryrdn index, it returns DB_KEYEXIST, which used to be ignored by resetting 0 (== SUCCESS). This patch returns DB_KEYEXIST to the caller and let _entryrdn_insert_key use the info to replace the temporary entryid with the real one. The error code is ignored by the other callers.
