Using Memcache as storage backend for Tokens in Keystone, we hit this bug: https://bugs.launchpad.net/keystone/+bug/1242620 It generates some bugs when running Tempest framework and also failures in our QA process. After some investigation, it seems the bug will not be fixed in Havana and we should switch to SQL backend. Another work will be done also on the MySQL keystone tables to avoid useless replication for large scale deployments. Bug #379 Signed-off-by: Emilien Macchi <emilien.macchi@enovance.com>
