Sorry, works for me fine here. Are you sure you don't have a group with
the same GID on the system in /etc/group or in another domain?

Can you run a more isolated test?

service sssd stop
rm -f /var/lib/sss/db/cache_*
service sssd start
getent group -s -sss $groupname_in_description

If you still don't see the groupname you'd expect, can you examine the
cache?

yum -y install ldb-tools
ldbsearch -H /var/lib/sss/db/cache_$domain.ldb objectclass=group

The last command should show the group entry exactly as stored in the
cache.
