Hello,

I am using Fiware's PEP proxy with the Keyrock. After installing the PEP
Proxy, I configured my config.js as:

config.account_host = '0.0.0.0:8000'

config.keystone_host = '0.0.0.0'
config.keystone_port = '5000'

config. app_host = 'www.google.com'
config.app_port = 80

As written in the guide and shown in tutorial videos, I have registered an
application on Horizon portal and received the username
'pep-proxy-65275fc866074e04bbd22ab05ac9f971' and its password. I have
entered these values in the config.username and config.password fields.
However, whenever I start the PEP proxy server with this command 'sudo node
server.js', I get the following error on PEP proxy server:

2017-01-25 12:51:19.671 - INFO: Server - Starting PEP proxy in port 80.
Keystone authentication ...
2017-01-25 12:51:19.971 - ERROR: Server - Error in keystone communication
{"error": {"message": "object of type 'NoneType' has no len()", "code":
400, "title": "Bad Request"}}

I read on stackoverflow that PEP proxy server requests a domain-scoped
token from keystone. I have tried requesting a domain-scoped token directly
from keystone by using the username
'pep-proxy-65275fc866074e04bbd22ab05ac9f971'
and its password. I get this error on keystone server:

The same error occurs when I try to request an unscoped token. It says that
the user could not be found. However, when I list all the users using
/v3/users, the user with name 'pep-proxy-65275fc866074e04bbd22ab05ac9f971'
appears on the list and is enabled. Am I missing something? How can I start
the proxy server with the given username and password?
