## Summary by CodeRabbit
* **Bug Fixes**
* End User Authentication and lock end-user info settings now
synchronize correctly when one is updated without explicitly setting the
other.

authentication must be enabled before locking end-user info.
* **Tests**
* Expanded test coverage for MDM configuration handling and related
scenarios.
