Hello,

I am new to FIWARE and I am using KeyRock - Identity Management. I have only
Keystone and Horizon installed. I have configured Keystone on a VM which I
access through ssh. I can run commands on keystone such as create/delete
groups, users etc. using 'curl'. Now, I am trying to do the same using the
browser after installing Horizon. I run Horizon at 0.0.0.0:8000 and access
the server via 'http://[public IP]:8000' in chrome. I get the following
error in browser:

A server error occurred. Please contact the administrator.

In the Keystone ssh, I get the following:

2017-01-02 22:45:25.597 4731 WARNING keystone.common.wsgi [-] Authorization
failed. The request you have made requires authentication. from 127.0.0.1

In the Horizon ssh console, I get the following error:

UserWarning: Module novaclient.v1_1 is deprecated (taken as a basis for
novaclient.v2). The preferable way to get client class or object you can
find in novaclient.client module.

Please tell me what am I doing wrong. As I am new to this so my
understanding about its functionality is quite limited.
