Question:
Fiware pep-proxy and idm communication issue

Description:
I wanted to connect pep-proxy with the idm .. so I followed the installation of pep from that link ..
https://github.com/ging/fiware-pep-proxy by building it from the source .
That was the config file i was supposed to edit

// Credentials obtained when registering PEP Proxy in app_id in Account Portal
config.pep =

i also wanted to know how could i get both the app_id and the trusted_apps parameters and i'm also confused with the meaning of the app_id whether it's the client id or not .

That was the first part of my issue.

when i put the client id with app id and put the username and password of pep proxy that i got when i registerd it on idm ,
i got keystone communication error

when i edited the idm host parameter by adding "http" at the beginning , i got no token and i get "token undefined" message .
Also when i edited the username and password by putting those of idm account , everytime i get a new token.
So i wanted to know the best way to build the fiware pep-proxy and make it communicate correctly with the idm with no problems .

Then i tried to follow the installation commands from the docker file . On building the pep-proxy with these commands , i got a new config file which is that of fiware academia

this config file is different from the first one i worked on . When i followed the steps in this video https://www.youtube.com/watch?v=dtKsjGbJ7Xc&index=10&list=PLARS-yIy9nOoBIOJS05Rpkvu1pZiNTgPT and configured the username and password by putting those of the pep-proxy , i got this error.

On putting "http" before keystone parameter as follows

config.keystone_host = 'http://cloud.lab.fiware.org';

i got this message

But on putting the username and password of idm in the configuration as shown below
config.username = 'idm_user_mail;
config.password = 'password';

i always get a new token .

Now , I want to know the best way to get the pep-proxy and the idm work together as i'm still struggling to make them communicate properly.
