Comment 2 for bug 1537076

This failure is seen only in n-cpu log, in ir-api I see the following:

2016-01-27 08:34:21.572 30788 DEBUG keystoneauth.identity.v2 [-] Making authentication request to http://127.0.0.1:35357/v2.0/tokens get_auth_ref /usr/local/lib/python2.7/dist-packages/keystoneauth1/identity/v2.py:62
2016-01-27 08:34:21.641 30788 DEBUG keystoneauth.session [-] REQ: curl -g -i --cacert "/opt/stack/data/ca-bundle.pem" -X GET http://127.0.0.1:35357/v3/auth/tokens -H "X-Subject-Token: {SHA1}6f4792750ecc5c46afececfa19849e2df8c71113" -H "User-Agent: python-keystoneclient" -H "Accept: application/json" -H "X-Auth-Token: {SHA1}f279ba41bea3ff4737634c791e70d6dbc1ba4758" _http_log_request /usr/local/lib/python2.7/dist-packages/keystoneauth1/session.py:225

So the request actually goes to v3, despite v2 is logged.
