I did my first production deployment of vCenter 5.1, and sure enough, there was a glitch. The admin of the system changed his mind on the VLAN scheme after Single Sign-On, the Inventory service and vCenter components were setup on a linked-mode DR vCenter. I didn’t have to do every step of KB 2033620 but it sure helped.
The new web interface sure is slick, but I keep bringing up up the old tried and true interface. VMware View sure has put me off of Flash, thats for sure.
SSO is not fun.
