We are running ACS version 5.4. We've connected the ACS successfully to a Microsof Windows 2008 Active Directory.
The problem we are facing is that an AD user is not able to match authorization policy rules created. Instead the authorization policy jumps straight to the default rule which is set to deny access.
The authorization rules are meant to ensure that the AD user depending on the rule they are in, is given specific privilege levels. eg. if you re in the group NetworkAdministrators in the AD you have privilege level 15 while the users in the group JuniorNetworkAdministrators, you have leve 7 privilege access to the devices.
Attached is the output of the process from the monitoring and report viewer.
