Guys, I'm trying to install Liberty on Ubuntu Trusty, I'm following the doc: http://docs.openstack.org/liberty/install-guide-ubuntu/keystone-install.html And, after running: --- openstack --os-auth-url http://liberty-1.mydomain.com:35357/v3 --os-project-domain-id default --os-user-domain-id default --os-project-name admin --os-username admin --os-auth-type password token issue Password: --- I'm seeing the following error on output: --- An unexpected error prevented the server from fulfilling your request. (HTTP 500) (Request-ID: req-31b76921-71ff-4dfe-9bcd-10a395925fc1) --- And on logs: --- http://paste.openstack.org/show/476623/ --- If I comment the file: --- driver = memcached --- Under [token] in /etc/keystone/keystone.conf, then, the problem goes away. But, is it okay? Is this only a documentation bug? Am I still using Memcached somehow, by default? Thanks! Thiago
