Comment 2 for bug 1698455

To fix, in the keystone-install.rst file, add a grant for 'keystone'@'controller' in the "Grant proper access to the keystone database" section:

[root@controller ~]# echo "GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'controller' IDENTIFIED BY 'KEYSTONE_DBPASS';" | mysql -uroot -pDBpass
[root@controller ~]# echo > /var/log/keystone/keystone.log
[root@controller ~]# su -s /bin/sh -c "keystone-manage db_sync" keystone;
