Red Hat Bugzilla – Bug 1264572
periodically a user gets logged out and cannot log back in (horizon)
Last modified: 2016-02-18 10:20:48 EST
Description of problem:
Every 10-60 minutes a user gets logged out and referred back to the login screen. At this point, every subsequent login attempt with proper creds fails.
Version-Release number of selected component (if applicable):
Not immediately reproducible.
The customer says that by opening up a private window each time this occurs, the logins are then accepted. They can also delete the cookies and then it works.
Actual results: Logins attempts only result in being sent back to the login screen.
Expected results: Login.
I can confirm this on my rdo kilo installation.

Cases are different. If I understand you right, you can not log in any more after being logged out. For that issue, one of two patches were merged upstream.
This is not an problem for RHOS, since that includes already a fix for that "value must be integer" issue.
I believe, this is due to a mis-configuration.
Session cookies become quite big; My assumption is, they get too big.
The situation becomes worse, when lots of services are enabled (service catalog is stored in cookie, or when using PKI tokens)
Changing session engine
and taking care, there is a cache like memcached enabled solved this issue for me.
FWIW, I filed a bug on openstack-puppet-modules to fix this some time ago:
We're already carrying the mentioned fix for a long time. I'm closing this bug, as I wasn't able to reproduce at all, and I haven't seen any other reports of this.
Please re-open, if you can reproduce.
