Geoff, your report confirms you are getting the correct behaviour. I'll assume that MNLipp is also seeing the same thing based on their comments. The issue you have reported about not being able to shutdown sounds like bug 861171. It makes sense that you can't shutdown from the greeter because another user is logged in, however the greeter should report this case and/or allow you to override this.
