Comment 1 for bug 1663866

Senthil debugged and figured out the following as suggestion:

there are two options to resolve the issue. Both are as below.
Soln1: is the deprecated mode where in admin_auth_url didn’t have v2.0 set under neutron section
Soln2: is the new way going forward where one has to specify auth_plugin to use and username was missing too.

[root@nodeh8 ~]# diff /etc/nova/nova.conf.soln.1 /etc/nova/nova.conf.bk

< admin_auth_url=http://10.204.217.112:35357/v2.0
