I installed SSO and the Web Client on a Windows Server in a test domain. This seemed to go fine but I found that it hadn't picked up a couple of domains or the ESX server in one of them. I added a DC from each of the missing domains as an identity source but this doesn't seem to have made any difference. The ESX server wasn't joined to the domain at the time but has been since, a DC for it's domain was also added as an Identity Source after this.
Is there any way to add it manually?
