Troubleshoot user creation issues with HR provisioning

15 September 2026Doc update+11 / −13 lines

In brief

The documentation now explains how to configure attribute value clearing, fallback values, or ignored values when HR applications return null or empty attributes during provisioning.

What Entra admins need to know

Review mappings where HR attributes may be empty. Enable clearing for both the source and target mapping when target attributes should be cleared; otherwise use a fallback or ignore expression as appropriate.
