Lots of SSO discussion here...
Anyway, I seem to be having a slightly different problem than the others I have been seeing. When I give admin rights to my vcenter instance to "domain admins", which my account is a direct member of, I can not log in. When I give my domain admin account direct permissions to the vcenter instance I can log in no problem.
Anyway, my environment is 2008r2, everything is up to 2008 functional levels, vCenter is installed into a fresh 2008r2 instance.
Anyone else seeing this behavior? Any suggestions? I will be doing more testing.
