Keystone's preferred deployment has changed to running within Apache httpd/mod_wsgi upstream. This offers better performance, stronger authentication mechanisms, and federation capabilities over using eventlet (keystone-all).
We should deploy Keystone in httpd/mod_wsgi for RHEL OSP 6.0 via all supported installation methods.
This bug will serve as a tracker for the various sub-tasks that are needed to complete this work across components.
