Symptoms

Deleted values reappear in multivalued attribute in a replicated Oracle Unified Directory (OUD) environment resulting in data inconsistencies as unexpected information are still present in entries and/or groups.

Attribute values that have been deleted are reappearing when multi valued attribute is updated two times (after replication purge delay time).

Steps to reproduce in a replication OUD environment:

1. Modify a multi-valued attribute with modify operation: changetype: modify / replace: attributeName  (for example, there are 20 values for the multivalued attribute, from Value1 to Value20)
2. Wait longer than the <replication-purge-delay> configured time
3. Delete values in the multivalued attribute with operation: changetype: modify / delete: attributeName (for example: delete Value10 and Value11)
4. Verify with ldapsearch that Value10 and Value11 are removed from attributeName, which they are and is expected/correct
5. Wait again longer than / past the replication-purge-delay time
6. Delete another value in the multivalued attribute with operation: changetype: modify / delete: attributeName (for example: delete Value18)
7. Verify with ldapsearch that Value18 is removed, which is expected/correct
8. Verify with ldapsearch to find that Value10 still exists when it should not, it should have remain removed / deleted but it is incorrectly re-added / reappears / returns
