Open Stack

Hello,

I'm trying to configure a "Kilo" server reading, step-by-step, the PDF 
manual. However, after installing and configuring dashboard, I can't 
connect with browser. Error log says: "TRACE keystone.common.wsgi 
AttributeError: 'Token' object has no attribute 'list_events'". My 
system is running only httpd.service, because I can't start 
openstack-keystone due to "Address already in use" (port 5000 and 35357)...

What am I doing wrong?

Thanks.
