From db60a1e654d2212fcc36145cf5e4ba0dd74ce622 Mon Sep 17 00:00:00 2001
From: Daniel J Walsh <dwalsh@redhat.com>
Date: Fri, 27 Aug 2021 08:12:56 -0400
Subject: Add support for libsubid

This will enable remote access to /etc/subuid and /etc/subgid
information from ldap services, if shadow-utils ships with a libsubid.

[NO TESTS NEEDED] Since we have no way to test this.
