Openstack Keystone version v2 and v3: what and when to use? about coa HOT 2 OPEN

Knowing that:

• openstack unified API supports both v3 and v2 for backwards compatibility.
• python-keystoneclient only supports the Identity v2.0 API

-This explains why keystone client doesn't work with API identity v3 (NOK in 2nd table).
-The following link may suggest that swift is not properly configured for v3 auth_url (NOK1 in 2nd table).

from coa.

I've collected the result of some commands hopping to have better view of the big picture.

Identity version 2.0 (http://X.X.223.25:5000/v2.0)

NOK = Could not determine a suitable URL for the plugin

Identity version 3 (http://X.X.223.25:5000/v3)

• NOK =Authorization failed the resource could not be found (HTTP 404)
• NOK1=Authorization failed. Authorization failed the resource could not be found

Stange that keystone.conf doesn't seem to have any reference to any auth_url:

cat /etc/keystone/keystone.conf | grep -v ^# | grep -v ^$
