Red Hat Bugzilla – Bug 1270213
sometimes I can't login into horizon
Last modified: 2015-10-30 06:33:10 EDT
Description of problem:
Sometimes I couldn't log in into Horizon with no obvious reason or any error message. It's quite confusing situation for end user, if he provide correct credentials and he is redirected to login page. I tried that with two users (demo, admin) and it doesn't work in both cases.
Version-Release number of selected component (if applicable):
1/20, quite rarely
Steps to Reproduce:
1. navigate to dashboard (like http://ip/
2. fill login form with valid credentials, click to Sign in button
User is not logged in although user/password combination was correct, also there is any displayed error message.
User should be logged in by first attempt.
Remove "sessionid" cookie (i.e. by FireBug), refresh page and try to log in again - this works in 100%.
Discovered in my local firefox v34 and openstack environment is running on RHEL 7.1
I assume, you have something in logs, esp about cookie size?
Created attachment 1081280 [details]
Part of horizon.log that is related to cookie size.
here you go.
SESSION_ENGINE = 'django.contrib.sessions.backends.cache'
to your local settings, make sure, you have a memcached installed and configured
systemctl restart httpd
I opened a bug about this a while ago on installer
