Comment 25 for bug 1405549

> can we create a separate bug or describe, why we need to set these options? We already have cache/backend set to "keystone.cache.memcache_pool" for both 6.0 and 6.1. Is not it enough?

You are talking about cache backend. There are many various backends in Keystone. For example, persistence drivers in tokens is one set of them. Now we use bad driver. We need to use a better one.
