yes, that's what I meant earlier with the missing view entry in the
cache. SSSD tries to figure out if a view name changed at startup time
and if it happened it removes the old view data. This does not work
properly because of the  issue we have and hence SSSD needs some help by
either doing a fresh view name change with the fixed version or remove
the existing cache.

yes, this is expected, but you do not have to add the group to
/etc/group but you can add a new group with the overridden GID to IPA as
well.
