Is there currently any ACS version working with Windows Server 2008 R2 domain controllers?
Our server stuff has recently upgraded the Domain Controllers to 2008r2 and turned off the 2003 servers. This didn't make our ACS 4.1.4 really happy.
I've read now serveral posts regarding issues with ACS and Server 2008r2 and hope to find a solution (besides switching to LDAP, yukk).
ACS can not currently be installed on a server running Windows 2008 R2.
As an alternative you can install ACS on a member server. The authentication
from ACS uses the local machine net APIs so authentication against a 2008
R2 domain will work. The Remote Agent can also not be installed on a 2008 R2
server if you are running the appliances.
If you install ACS on a member server instead here is how you set up the services
to correctly authenticate with the domain:
