Subject: [PATCH 8/8] negcache: do not use default_domain_suffix
When splitting the names from the filter_users and filter_groups options
do not use the default_domain_suffix because it will hide that the
original name is a short name and should be added everywhere.
Additionally this patch fixes a typo where sss_parse_name() was used
instead of sss_parse_name_for_domains().
Resolves: https://github.com/SSSD/sssd/issues/5238
