ADSIEDIT replacement and tools, LDAP Export/Backup, ldifde
When people have done things wrong or not ended Migrations as they should that may be the time you use ADSIEDIT to remove wrong attributes or even restore them. Most of the times when we have cases with MS Support MPSS they compare their test labs or reference db with the customers and delete or add Attributes, Classes or keys.

Systernals Active Directory Explorer (AD Explorer) is an advanced Active Directory (AD) viewer and editor. You can use AD Explorer to easily navigate an AD database, define favorite locations, view object properties and attributes without having to open dialog boxes, edit permissions, view an object’s schema, and execute sophisticated searches that you can save and re-execute.
AD Explorer also includes the ability to save snapshots of an AD database for off-line viewing and comparisons. When you load a saved snapshot, you can navigate and explore it as you would a live database. If you have two snapshots of an AD database you can use AD Explorer’s comparison functionality to see what objects, attributes and security permissions changed between them.
