I am new to FIWARE. On my Ubuntu 16.04, I have setup Fiware's KeyRock which is a combination of OpenStack Keystone Identity Management and Horizon Dashboard. I have used this guide to set up everything.
After installing Keystone (which is a RESTful API), I have used curl to send HTTP requests and everything is working fine, i.e. I can run these commands on the keystone server using curl.
However, when I run Horizon on the same server using the reference Django project located in the openstack_dashboard directory with:
sudo tools/with_venv.sh python manage.py runserver 0.0.0.0:8000,
Horizon server starts with no errors but when I access it via browser, I get the following error:
A server error occured. Please contact the administrator
On the Keystone server console, I get the following error:

I am sending a GET request via the browser but the Keystone server is receiving a POST request as indicated in its console output. I don't understand why is this so.
It looks like the Horizon server is not able to verify the credentials.
In the case of Fiware, you would get this error on Horizon server if the file local_settings.py (located in the /horizon/openstack_dashboard/local/ directory) is not properly configured. In this file, there is a dictionary named IDM_USER_CREDENTIALS where you have to set the password for the admin profile that was created when you populated the database of Keystone. It is also given in the link that you provided. Try changing the password and see if it works.
