Bug Description
This bug tracker is for errors with the documentation, use the following as a template and remove or add fields as you see fit. Convert [ ] into [x] to check boxes:

- [x] This doc is inaccurate in this way:

By following the instructions to setup the /etc/openstack-dashboard/local_settings configuration file on CentOS 7, I received a "Not Found - The requested URL /auth/login was not found on this server." error when attempting to load horizon at <controller_url>/dashboard in a browser.

It appears horizon tries to re-direct to a URL outside of the /dashboard URL, causing the 404. This is due to not having a "WEBROOT" setting in the file.

By adding the following to the config file (and restarting httpd), the horizon dashboard then loads without issue:

WEBROOT = '/dashboard'

My apologies if this is the incorrect place to request this documentation addition.

Thanks!
