Dear all, in this guide ( https://github.com/cloudkeep/barbican/wiki/Barbican-Options:-authentication-with-Keystone) I see two uses of Keystone: 1 - Configuring Keystone for use with barbican<https://github.com/cloudkeep/barbican/wiki/Barbican-Options:-authentication-with-Keystone#configuring-keystone-for-use-with-barbican> ; 2 - running Openstack Keystone Authentication Middleware on the Barbican API node<https://github.com/cloudkeep/barbican/wiki/Barbican-Options:-authentication-with-Keystone#running-openstack-keystone-authentication-middleware-on-the-barbican-api-node> . So, what is the exactly difference between the two uses of Keystone? Thank you so much. I wish you a happy new year!
