+The module also assigns special properties to two local groups, if
+they exist:
+
+• If the local group ‘nss-nonlocal-users’ exists, then nonlocal users
+ will be automatically added to it. Furthermore, if a local user is
+ added to this group, then that user will inherit any nonlocal gids
+ from a nonlocal user of the same name, as supplementary gids.
+
+• If the local group ‘nss-local-users’ exists, then local users will
+ be automatically added to it.
