I'll try asap on 2.2 but in the meantime, can you tell us if you managed to reproduce the problem on a 2.4.x version of httpd? Moreover, if you have a simple script or way to reproduce your backend (returning 401) please share it with us so we'll be able to track down the issue quickly. Thanks! Luca
