Testing Proxy as per readme.md gives an unexpected response

[YatinArora-NEC]

Hi All
I am facing issue in this command curl --header "X-Auth-Token:z2zXk...ANOXvZrmvxvSg" http://proxy_host.
I am confused what proxy_host means here .

I tried with curl --header "X-Auth-Token:<oauth2_token>" http://pep-proxy-ip:port-no and received response as "User Token not authorized".

But from here "https://github.com/ging/fiware-pep-proxy" curl --header "X-Auth-Token:z2zXk...ANOXvZrmvxvSg" http://proxy_host it gives result as

"Once authenticated, the forwarded request will include additional HTTP headers with user info:

X-Nick-Name: nickname of the user in IdM
X-Display-Name: display name of user in IdM
X-Roles: roles of the user in IdM
X-Organizations: organizations in IdM "

How can i get the above result from this command curl --header "X-Auth-Token:z2zXk...ANOXvZrmvxvSg" http://proxy_host
