Does anyone know how to compare before and after snapshots of the AD schema when installing a product that will modify it? My customer is concerned about the schema being modified by a ?Cognos? product. My feeling is there has to be a way to do this in a test environment and export the schema before and after the changes. Then run a utility on them to find out what has been changed or ?modified?, although modifying an existing object in the schema would be extremely stupid on Cognos part, I still need to verify that its not doing it.

The only product that I work with that changes AD schema is Exchange 2000.
I don't know if the same thing will apply the Cognos product.
E2K adds over 1000 classes and attributes to the schema. It uses (as far as I can tell) LDIFDE to incorporatechanges that are contined in *.ldf files.
The presence of ldf files would be a dead giveaway...

Cognos does modify the schema, after researching their changes I found that they were not affecting the directory adversely. The 3 tools I used to check the classes and attributes installed to the schema were: Active Directory Schema Manager, Schemadoc.exe and Windiff.
