I have added the AD successfully from the vcenter console and also configured the Single Sign On.
When I try to retrieve the users from the AD, I first set the domain in the Users and Groups tab, then after a while I get the following error:
So, I attempted to do the same procedure using the Desktop client.
But, I get the following error.
Call "UserDirectory.RetrieveUserGroups" for object "UserDirectory" on vCenter Server "gspsec-vcenter" failed.
I cannot understand as to what I doing wrong. There is no firewall in between. IN fact, the AD is a VM on the same ESXi that the vCenter is managing.
