One day I needed to implement identity synchronization and federation. So, I installed dirsync, plus ADFS. All worked fine and as expected.
I deleted all those instances, the Domain Contoller, the Exchange Mailbox Role and the ADFS.
I thought it was going to be much more complex considering the ADFS doesn't exist anymore, but no.
