You must create a user account in Active Directory to use with vCenter Server. You specify this user account when you add a vCenter Server instance in Horizon Administrator.

You must give the user account privileges to perform certain operations in vCenter Server. You can create a vCenter Server role with the appropriate privileges and assign the role to the vCenter Server user. The list of privileges you add to the vCenter Server role varies, depending on whether you use Horizon 7 with or without View Composer. See Configuring User Accounts for vCenter Server, View Composer, and Instant Clones for information on configuring these privileges.

If you install View Composer on the same machine as vCenter Server, you must add the vCenter Server user to the local Administrators group on the vCenter Server machine. This requirement allows View to authenticate to the View Composer service.

If you install View Composer on a different machine than vCenter Server, you do not have to make the vCenter Server user a local administrator on the vCenter Server machine. However, you do have to create a standalone View Composer Server user account that must be a local administrator on the View Composer machine.
