I am about to start testing a massive project which is using Microsoft Forefront Identity Manager and shibboleth.

Has anyone tested these sort of setups and if so got any advice.My thinking currently is:

1)Testing to make sure the servers are setup correctly.

2) Then look at making sure all the servers are integrated correctly.

3)Look at customer portal facing side and

4)Then finally load testing.

Any advice on specifics I should look out for in terms of testing would be greatly appreciated.
