The following setup is required for Creating NFSv4.1 datastores with Kerberos authentication:

• For Kerberos authentication to work, you need to make sure that the ESXi hosts and the NFS server are joined to the Active Directory domain
• Create a new or select an existing AD user for NFS Kerberos authentication
• Configure the NFS server/share to allow access to the AD user chosen for NFS Kerberos authentication
