Creating authentication policies

Before we create policies, we need to enable DAC support for domain controllers and devices. DAC allows administrators to apply access control permissions and restrictions based on rules that can include the characteristics of the resources.

2. Edit Default Domain Controllers Policy.
3. Go to Computer Configuration | Policies | Administrative Templates | System | KDC.
4. Click on Enabled to enable KDC support for claims, compound authentication, and Kerberos armoring.
