Bug Description

I deployed multi-Keystone installation using DevStack HAProxy plugin - https://review.openstack.org/#/c/399472 and faced a caching issue.

If we enable caching in /etc/keystone/keystone.conf, tempest test tempest.api.identity.admin.v3.test_roles.RolesV3TestJSON.test_role_create_update_show_list will fail because if a role was updated using Keystone1, then Keystone2 can't see there changes.

So what kind of caching did you implement? If you are running multi-node, then you will have to have a common memcache that is shared by both nodes, to avoid exactly this problem.

Hi Henry, thank you for answer. I used oslo_cache.memcache_pool but my memcache wasn't shared.
