Comment 1 for bug 1418341

Hello chenglch.

this is not problem . because the following configuration is invalid.
>[keystone_authtoken]
>password = secretservice
>username = ironic

the correct configuration is bellow.
>[keystone_authtoken]
>admin_password = secretservice
>admin_user = ironic
>admin_tenant_name = service

But if the invalid configuration file is created by devstack , Please display your version of devstack.
At least I have confirmed that current master branch of devstack is working well.
