I came across a problem attempting to install the SCSM prerequisite "Authorization Manager Hotfix" when installing SCSM on Server 2008 R2 with SP1. It said that it is not applicable, but it still shows a warning.
IT IS NOT NEEDED. What is my source? Well, unfortunately, a comment made by Travis Wright. But it is good enough for me, and it seems to work fine without it.
I quote "The Authorization Manager hotfix is not required on Win2k8 R2 SP1"
