Hi Nicolas -
Glad you like the book! Jacek Artymiak gets all the credit for it, and
he wrote and tested it against TryStack. So for now, it uses old-style
Keystone requests as those will work against TryStack.

TryStack plans an upgrade in April, not to steal thunder or anything
from them, but I'd expect we can do updates to the guide after that.

If you wouldn't mind, could you log a doc bug to track that effort,
basically requesting Auth content updates to go with Keystone
light/redux? Log it in http://bugs.launchpad.net/openstack-manuals.

Thanks,
Anne
