Comment 2 for bug 1742663

To clarify, I was trying to use the following environment file:

(undercloud) [stack@undercloud ~]$ cat disable_v2.yml
parameter_defaults:
  ControllerExtraConfig:
    controller_classes:
    - keystone::disable_v2_api

That Puppet class was something I copied into the guest manually, and when executed locally it functions as expected. I ran into this bug when I couldn't figure out why it wasn't being called by TripleO. Thanks for your help.
