Comment 1 for bug 1113146

I suspect the CI tests on jenkins.openstack.org succeeded because it is using keystoneclient 0.2.2 rather than the latest from git.

Commit 3dfb8437 in keystoneclient introduced a flag called _use_keystone_cache in keystoneclient/middleware/auth_token.py (in _cache_store):

        # we need to special-case set() because of the incompatibility between
        # Swift MemcacheRing and python-memcached. See
        # https://bugs.launchpad.net/swift/+bug/1095730
        if self._use_keystone_cache:
            self._cache.set(key,
                            data_to_store,
                            time=self.token_cache_time)
        else:
            self._cache.set(key,
                            data_to_store,
                            timeout=self.token_cache_time)

That flag is set to false in the keystone tests even though they are using "FakeMemcache" which should use the time= kwarg rather than timeout.

Since LP 1095730 has been resolved I think the _use_keystone_cache flag can be removed altogether and this integration bug between keystone and keystoneclient will be resolved.
