network related command returning SSL Error

[Arnaud]

I'm currently installing openstack following the tutorial for ocata on ubuntu-server.
After installing and configuring neutron on the controller and the first compute-node, any command related to the network that I tried failed and returned an SSL Error.

openstack extension list --network, openstack network list and openstack network agent list all return :
'unicode' object has no attribute 'get'

openstack extension list works fine, same for openstack user/service/project list

This is the tail of /var/log/neutron/neutron-server.log

So, after some tedious investigation, I finally found a way to solve this issue. But even though it's working now, I feel this is kind of an odd solution
Anyway, after looking at the traffic using tcpdump, I realized there was a strange tra

[Arnaud (7r17r1)]

Can't edit an answer ? x)
Anyway, sorry about that....

There was a strange frame to which the server answered "SSL error", but the frame was not an SSL request, I don't really know what it was
There was no reason for the server to answer SSL request since there were no SSL or https option anywhere in all my config files related to openstack

The issue was resolved by editing neutron.conf and adding :

identity_uri = http://localhost:35357
admin_user = admin
admin_password ADMIN_PASSWORD
admin_tenant_name = admin
auth_type = password

not sure why it needed that though, since neutron is supposed to have admin credential from openstack roles

I still think that it's either a bug or a lack of information in the tutorial
