I am writing to enquire if anyone has had any exposure to testing of the following applications and can offer any advise on the use of particular techniques or tools that have proved useful.  any assistance you could offer would be most appreciated.

 - Microsoft Active Directory
 - Microsoft Active Directory Application Mode
 - Microsoft Forefront Identity Manager

The challenge
development and configuration changes made to one or more of the applications detailed above  can have far reaching/unwanted implications, both in the applications themselves and for upstream/downstream applications they interact with.   Functional/front end driven testing alone will not provide confidence from a regression perspective

The solution
A tool/technique is required that can inspect/export/compare triggered configuration/code/data changes as a result of a modification.
