Thank you so much. Seems I need to rewrite resource driver, but I didn’t find where the Keystone uses the `[resource] driver` option. The Resource Manger just creates an instance of resource_sql.Resource.
I changed the `[resource] driver` option to `sql1` in the `/etc/keystone/keystone.conf` file and everything works fine :)
