although this answer is 'correct' it is also not helpful. I'm not going to have every user login with the same account just to see VDP tasks. Is there no solution to this?
Furthermore, the tasks show up in the VI C# client when I'm logged in with my regular user. It makes little sense that I would have to use a different account in the web interface.
I have a vague recollection that the install guide talked about setting users as administrators on the VDP system in order to manage it and I have seen errata for some Vmware products that state if you use the wrong format for the username during registration that the tasks will not show up but I have tried both formats (user@vsphere.local and vsphere.local\user) during registration.
I'm hoping someday someone will read this and have more insight into what is going on.
