Description Matthias Runge 2015-08-20 11:49:02 UTC 
Description of problem:
/etc/openstack-dashboard/local_settings
misses
 
SESSION_ENGINE = 'django.contrib.sessions.backends.cache'

We're currently not setting up a memcache, but not setting to use it as store for sessions

Horizon uses signed cookies by default for session storage. Unfortunately, this has a size limitation of 4k.
Comment 3 Matthias Runge 2015-09-18 19:08:22 UTC 
Better option is to set up a database for horizon session data, memcached and to use 
SESSION_ENGINE = "django.contrib.sessions.backends.cached_db"

Comment 5 Emilien Macchi 2015-12-02 19:37:41 UTC 
which installer are you taking about?
puppet-horizon already supports django_session_engine parameter in init.pp - I'm interested to know what change you want in OPM.
Comment 6 Matthias Runge 2015-12-02 20:35:57 UTC 
The last time (about a week ago) I used packstack, and the setting from comment#3 was not added (or something similar)
Comment 7 Matthias Runge 2015-12-02 20:36:55 UTC 
Oh, btw. it was rhos-8 that I installed for my local tests here; I don't have the environment to use osp-d.
Comment 9 Javier Peña 2016-05-19 16:51:03 UTC 
I have proposed https://review.openstack.org/318775 with a fix. The patch uses memcache as backend and 'django.contrib.sessions.backends.cache' as SESSION_ENGINE, since setting up a database for caching would go beyond the Packstack use case.

Fixed was merged so closing this.
