You want to configure Active Directory domain controller access for NetApp ONTAP cluster administration.

To enable Active Directory (AD) domain users and groups to access the cluster or SVMs for administration purposes, you need to set up an authentication tunnel through an SVM that has a CIFS server created and joined to the domain. This can be either an existing CIFS SVM or a dedicated admin SVM. You also need to use the vserver active-directory create command to create a computer account on the domain for the SVM that you want to access. This command works for both CIFS and non-CIFS SVMs. Configuring an authentication tunnel through anadmin SVM or an existing CIFS SVM are both valid actions to accomplish this task. However, using the vserver active-directory create command to create a computer account on the domain for a CIFS SVM is not necessary, as this is done automatically when the CIFS server is created and joined to the domain. References :- Configure Active Directory domain controller access overview, How to configure AD authentication for cluster when CIFS is not licensed, Create a CIFS server
