I wonder if anyone has come across this problem before or can point me in the right direction?
I have setup the vCenter 5 appliance and connected it to AD, I then associated the domain admins group with the Administrator role in vCenter.
When I try to login to vCenter using the vSphere Client I can't login when I select "Use Windows session credentials" however if I manually enter the username "domain\administrator" and associated AD password then I can login fine.
This is the same for any other domain account in the domain admins group. I've also tried specifically associating the administrator or other domain account with the Administrator role rather than using the domain admins group.
Many thanks
Matt
