Title: #128: Fix group renaming issue when "id_provider = ldap" is set
BTW I am not sure whether fix is sufficient. base on comment
called which invalidates entries + memory cache
But there were some bugs where people noticed "corrupted" memory cache after
renaming groups. And I doubt they called `sss_cache` for invalidating entries.
It would be good to check that use-case as well. I will check myself on Friday if nobody
else has a time.
Removing accepting label before such investigation.
