From c6b577caefb7ea2f9a73229f94703792b66f7a8f Mon Sep 17 00:00:00 2001 From: Arjun Shankar Date: Mon, 2 Oct 2023 14:55:18 +0200 Subject: Remove 'shadow' and merge into 'nss' The majority of shadow routines are entry points for nss functionality. This commit removes the 'shadow' subdirectory and moves all functionality and tests to 'nss'. References to shadow/ are accordingly changed.
