One of the new features in Windows Server 2012 R2 to decrease complexity is the so called Active Directory detached cluster. This is a regular Failover Cluster, but without a computer account in Active Directory. So, when deploying the Failover Cluster there’s no need to pre-create the Computer Name Object (CNO) anymore, but please note that the individual Cluster nodes still need to be a member of the Active Directory domain though.
Since the CNO is no longer available in an Active Directory detached cluster, the Cluster Administrative Access Point (CAAP) is not available either and in turn this cluster AAP was used by the Failover Cluster Management to access and manage the cluster. Since the cluster AAP is no longer available this is also referred to as an AAP-less, cluster AAP-less or CAAP-less cluster.
