OpenStack Dashboard (Horizon)

login to horizon fail while using keystone http mode

Asked by Liran Cohen

i am getting the following error :
unsupported operand type(s) for +: 'NoneType' and 'str'
Exception Location: /usr/lib/python2.7/dist-packages/neutronclient/client.py in authenticate

while trying to login as admin to the openstack dashboard.
The cli is working as expected but horizon is broken.
I tried to find some info related to this issue and the only related issue was due to some re-auth of neutron client.

if i switch back to the keystone standard mode (not http mode) everything is working as expected including the dashboard but i have to use the http mode cause the keystone can't handle the load with a single worker.

I just migrated from grizzly to havana (2013.2.2) running on ubuntu 12.04.3 TLS with keystone under http (ssl = false).

Not sure its related to horizon but hope i will get some information that will help me solve this issue.

Regards

Hi Liran, you might want to use http://ask.openstack.org to ask for help as Launchpad Questions are deprecated. I've only seen this happen in the case that you mention, when Horizon fails to authenticate with Neutron correctly usually because the token has expired...
