Re: [Rdo-list] Autoscaling stack croaks warning messages about trustee

You also need to configure heat to use keystone v3. Packstack,
at least as of Kilo, was still configuring keystone v2.0 by default,
see https://bugs.launchpad.net/packstack/+bug/1464371 (my bug report)
Trust delegation requires the v3 API, unless I've missed something.

There appear to be a number of issues with globally enabling keystone v3
being addressed in Red Hat OpenStack Liberty version, many of the bugs
in this query are related to keystone v3 bugs:
https://bugzilla.redhat.com/buglist.cgi?quicksearch=keystone%20v3

It doesn't look like you want to globally set Keystone v3 while these
are bugs outstanding, but you can change it in the Heat config file directly
to only affect the Heat service.

Trust delegation requires the v3 API in the line above
