HA Grafana, two servers one MySQL db

Grafana Configuration
1

As Grafana tutorial site: http://docs.grafana.org/tutorials/ha_setup/ is not very helpful in this matter: If I want two Grafana instances talking to single MySQL db, do I need to do anything special or just:

[database]
type = mysql
host = 1.2.3.4:3306
name = grafana
user = user
password = password

[session]
provider = mysql
provider_config = user:password@tcp(1.2.3.4:3306)/grafana

in the grafana.ini config file should be enough?

Edit:
Users are kept in LDAP if that makes any difference.

If you use v6.0 you do not need the session part either.

A shared MySQL server should be all you need
