Yes, if the public endpoint is set without a version then the service can deal with either version. http://paste.openstack.org/raw/412819/ That is not true for the admin endpoint (authentication is already done, the admin services deals only with tokens), at least for now, Keystone devs are working on it. >> 2 - openstackclient should be able to interpret v3 requests and append >> "v3/" to OS_AUTH_URL=http://keystone-server.5000/ or rewrite the URL >> if it is set as >> OS_AUTH_URL=<http://keystone-server.5000/>http://keystone-server.5000/ > > It does, if it can determine from the given authentication arguments if > it can do v3 or v2.0. > It effectively does, again, assuming the path doesn't contain a version number (x.x.x.x:5000) >> 3 - All deployments require /etc/keystone/keystone.conf with a token >> (and not simply use openrc for creating additional endpoints, users, >> etc beyond keystone itself and an admin user) > > No. What I said about this issue was "Most people using > puppet-keystone, and realizing Keystone resources on nodes that are not > the Keystone node, put a /etc/keystone/keystone.conf on that node with > the admin_token in it." > > That doesn't mean the deployment requires /etc/keystone/keystone.conf. > It should be possible to realize Keystone resources on non-Keystone > nodes by using ENV or openrc or other means. > Agreed.

I'm not sure what's the issue besides the fact keystone_puppet doesn't generate a RC file once the admin user has been created. That is left to be done by the composition layer. Although we might want to integrate that. If that issue persists, assuming the AUTH_URL is free for a version number and having an openrc in place, we're going to need a bug number to track the investigation. >> >> If anyone can speak up on these items, it could help influence the >> outcome of this patch. >> >> Thank you for your time. >> >> Best Regards, >> Matthew Mosesohn Thanks, Gilles >> >> On Fri, Jul 31, 2015 at 6:32 PM, Rich Megginson <rmegg...@redhat.com >> <mailto:rmegg...@redhat.com>> wrote: >> >> On 07/31/2015 07:18 AM, Matthew Mosesohn wrote: >> >> Jesse, thanks for raising this.
