After the initial deployment of your vCenter Server Appliance and Platform Services Controller, one of the first things that you want to do if you are using Active Directory is to join your PSC to the domain. In this blog post we are going to walk through doing just that. Like Active Directory domain controllers, the PSC really depends on time being synchronized within your network. The easiest thing to do would be to point all of your devices to the same NTP source. So before beginning, make sure the time is the same on all your devices. Once you have verified that, log into the PSC web UI as the admin account.

Navigate to Appliance Settings > Manage to see the Active Directory settings. Click Join.

Enter in your domain name and a username and password that has domain admin rights. Click OK.

Navigate to Configuration > Identity Sources. Click Add.
