The logs didn't seem to give any additional info. Do you have less than
10,000 groups in your AD? You can set that as high as you want. You will
need to restart the winbind service. You probably do NOT want to clear the
id cache, this will mess up your old rids. We use idmap_hash which has 10
digits in the id and gid, so you can go very high, you just have to be
careful that some apps don't have problems. We only found a problem with a
database that stored the uid and it wasn't wide enough.
