I should have mentioned in the patch:

According to [1] the "authenticate" signal returns FALSE when credentials are not set, returns TRUE when they are set, I don't see a way how to "forward" info why they weren't set.
However the "CANCELLED" error exists in librest [2] so maybe implementing new signal / api in librest and handling REST_PROXY_ERROR_CANCELLED in libgovirt is possible solution
