[Bug 1513216] Re: Mismatched keystone api version produces cryptic 'Error: Openstack'

 

This is mostly fixed with our transition to keystoneauth:

stevemar@ubuntu:/opt/stack/keystone$ openstack user list
Could not determine a suitable URL for the plugin
stevemar@ubuntu:/opt/stack/keystone$ export OS_AUTH_URL='http://172.16.240.199:5000/v3'

Title:
  Mismatched keystone api version produces cryptic 'Error: Openstack'

Status in OpenStack Identity (keystone):
  Invalid
Status in python-openstackclient:
  Fix Released

Bug description:
  The 'openstack' cli tool defaults to keystone version 2.0.  When
  pointed to a v3 endpoint, it fails like this:

  $ openstack service list
  ERROR: openstack 

  This can easily be resolved by setting OS_IDENTITY_API_VERSION=3 --
  that's not obvious from the error message, though, and isn't even
  obvious from log- and code-diving.

  I propose that we actually detect the api version mismatch and error
  out with a helpful message.
