From e481437ab9ebe9a8bf8fbaabe986d42b2f765991 Mon Sep 17 00:00:00 2001
From: Iker Pedrosa <ipedrosa@redhat.com>
Date: Tue, 3 Aug 2021 08:57:20 +0200
Subject: [PATCH] usermod: allow all group types with -G option
The only way of removing a group from the supplementary list is to use
-G option, and list all groups that the user is a member of except for
the one that wants to be removed. The problem lies when there's a user
that contains both local and remote groups, and the group to be removed
is a local one. As we need to include the remote group with -G option
the command will fail.
This reverts commit 140510de9de4771feb3af1d859c09604043a4c9b. This way,
it would be possible to remove the remote groups from the supplementary
list.
