Moving to 4.1.z based on discussion w/ Mo. Frederic if there's a quick+low risk fix you can land for this before code freeze for 4.1.0, we'd still take it i think. I think this should be a fairly quick+low risk fix indeed. We're looking into it. issue is fixed with payload: 4.1.0-0.nightly-2019-05-09-182710 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.

It should only update when the role binding is different than the expected value.
