I am in the process of installing Pike and when I logged into Horizon and selected an item in the tree on the left such as instances. I would get logged out stating that was not authorized. I figured out that the auth_uri is wrong in the [keystone_authtoken]
7 z, i8 a4 q, D" k. R6 S
6 G5 L5 f7 |% T4 D/ U+ FOriginal line: auth_uri = http://controller:5000
6 u$ @" J# A& L% T
Update line: auth_uri = http://controller:5000/v3

You can see in the admin-openrc and demo-openrc files they use the http://controller:5000/v3 for authentication.
/ p' a$ ~4 A& N: o, [$ S
Once I made this change in all of the appropriate files and rebooted i was able to log into Horizon and navigate as expected. This is an error in their documentation for installing Pike.
