I'm looking at your test case now. One thing to note, serverIDs must all be non-zero in a multi-master configuration. serverID == 0 is only valid in single-master replication.
When a "Refresh Present" phase is performed at a multi-master consumer, objects that were deleted at the provider while the consumer was down are not deleted from the multi-master consumer (if the provider is brought down and back up after the consumer is down). This problem can be duplicated as follows:
- Start provider
- Start consumer, which is configured as a multi-master server
- Add 10 records to the provider and wait until the records are replicated to
the multi-master consumer 4. Stop the consumer 5. Delete 3 of the records that were added to the provider 6. Stop the provider 7. Start the provider 8. Start the consumer 9. After giving the consumer time to perform the refresh present phase, the 3 records that were deleted at the provider while the consumer was down are still present on the consumer and were not deleted during the refresh present phase
Note: the consumer database must have a contextCSN attribute value present for itself (e.g., there should be 2 contextCSN attribute values present in the consumer database, one for the provider (in my configuration, this is serverID 000), and one value for the consumer (in my configuration, this is serverID 001). An example of the contextCSN values follows:
dn: dc=authentx objectClass: top entryUUID: 8eb6b259-ab66-49bd-b012-674c4f0fba8f contextCSN: 20101012154030.379053Z#000000#000#000000 contextCSN: 20101012141508.956053Z#000000#001#000000
OpenLDAP 2.4.23 is being used, along with Berkeley 4.6.21 (plus patches).
