Hello,
I'm having problems with my VSphere 5.1 setup (essentials edition, max 3 hosts). I installed the vcenter virtual appliance without any problem but I can't add AD users to the permissions configuration.
The vcenter appliance shows up in AD just fine and "domainjoin-cli query" tells me the appliance is domain joined.
I've added some screenshots to illustrate my problem.

I have no option to select AD users


My management screen seems to be limited compared to screenshots I found on the internet. When I click on "configure authentication", nothing happens. I have re-run the Setup Wizard to no avail.
I have no problem joining separate esxi hosts to AD and logging into them using AD accounts.
