Limitation: Uniqueness Is Not Enforced in Pre-existing Data

We recommend that you enable unique attributes only on empty directories or new attributes. This ensures uniqueness.

There is no DSA mechanism to find duplicates in existing directory data. Before you enable unique attributes on a running directory, you should check for duplicate attribute values.

If you load data using the DXloaddb tool, uniqueness is not enforced.
