Yeah, clarification from keystone folks would be really helpful. If Nikolay’s info is correct (I believe it is) then I actually don’t understand why trusts are needed at all, they seem to be useless. My assumption is that they can be used only if we send requests directly to OpenStack services (w/o using clients) with trust scoped token included in headers, that might work although I didn’t checked that yet myself.
So please help us understand which one of my following assumptions is correct? We don’t understand what trusts are. We use them in a wrong way. (If yes, then what’s the correct usage?) Trust mechanism itself is in development and can’t be used at this point. OpenStack clients need to be changed in some way to somehow bypass this keystone limitation?
