OpenStack Dashboard (Horizon) Fails to Allow Log In

I cannot log in to the OpenStack Dashboard; attempting to do so results in a re-direct back to the log-in page. Running Folsom on Ubuntu Server 12.10.

Entering the wrong details will throw an "incorrect user/pass" error; the correct details will show nothing.

I cannot see any issues in /var/log/nova-api.log or similar.

My apache2/error.log does show some 401's relating to Cinder, but I'm not sure if these are a red herring:

nova-manage service list shows smiley faces, and keystone service-list shows the expected services with no errors.

I'd appreciate some advice here—a Google hasn't helped.

Until Grizzly, Horizon would log you out if receiving a 401/403 not authorized error [0] -- so this is probably what's happening there, you are getting logged out before the page has finished loading. You should investigate what is causing the Cinder error.

This fixed it. I rectified the 401's (caused by incorrect credentials in /etc/cinder/api-paste.ini) and restarted the cinder processes.

We've seen this at CERN with Folsom. The workaround was to restart keystone.

Root cause was not understood and we'll be retesting with Grizzly to see if the problem occurs there.

Thanks for the response. Restarting keystone and/or the server doesn't seem to resolve the issue unfortunately. Keystone's own logs have nothing, either, which hasn't been helpful.

I already saw this and I same as you didn't know how to fix it, so I deleted keystone database and recreated all users, roles, services, etc. That is probably something related to keystone.

Did you try to run sync: keystone-manage db_sync

I have, with no luck. I'm trying to avoid dropping the keystone DB if possible.

Hey hassaan -- you should open a new question describing your issue, you're more likely to get answers this way. Make sure to include the error messages you're getting and any stack trace you can see in the logs.
