  We outline how the Wald entropy formula naturally arises in loop quantum
gravity based on recently introduced dimension-independent connection
variables. The key observation is that in a loop quantization of a generalized
gravity theory, the analog of the area operator turns out to measure, morally
speaking, the Wald entropy rather than the area. We discuss the explicit
example of (higher-dimensional) Lanczos-Lovelock gravity and comment on recent
work on finding the correct numerical prefactor of the entropy by comparing it
to a semiclassical effective action.
