> +Question:+
> Unable to authenticate users for an app in Fiware Lab KeyRock instance
> +Description:+
> I have registered two users in Keyrock (the global fiware labs instance at https://account.lab.fiware.org)
> User Robin has an organisation Robin-Cloud
> User Robin is owner of an application Babbler 
> The application Babbler has authorized users "Robin" and "Robin viewer" (see screenshot) 
> User "Robin viewer" is a member of the same organisation as user "Robin"
> Just to be sure i authorized the whole organisation that "Robin viewer" belongs to.
> Both users have the same roles.
> I can authenticate user "Robin" using a shell script to get an Access token. In the shell script i pass in the Applications Client ID and Client secret. I also pass in the username and password of User "Robin". The shell script is here (altered copy of this https://raw.githubusercontent.com/Bitergia/fiware-chanchan-docker/master/images/pep-wilma/4.3.0/auth-token.sh ):
> #!/bin/bash
> if [ $# -lt 2 ] ; then
>     echo "auth-token: missing parameters."
>     echo "Usage: auth-token <user-email> <password>"
>     exit 1
> fi
> # Retrieve X-Auth-Token to make request against the protected resource
> function get_token () {
>     if [ $# -lt 2 ] ; then
>     echo "get_token: missing parameters."
>     echo "Usage: get_token <user-email> <password>"
>     exit 1
>     fi
>     local _user=$1
>     local _pass=$2
>     # Retrieve Client ID and client Secret Automatically
>     CLIENT_ID="e2c095aa42414e75b9ac4d760f4c625a"
>     CLIENT_SECRET="****"
>     # Generate the Authentication Header for the request
>     AUTH_HEADER="$(echo -n ${CLIENT_ID}:${CLIENT_SECRET} | base64)"
>     # Define headers
>     CONTENT_TYPE="\"Content-Type: application/x-www-form-urlencoded\""
>     AUTH_BASIC="\"Authorization: Basic ${AUTH_HEADER}\""
>     # Define data to send
>     DATA="'grant_type=password&username=${_user}&password=${_pass}&client_id=${CLIENT_ID}&client_secret=${CLIENT_SECRET}'"
>     # Create the request
>     REQUEST="curl -s --insecure -i --header ${AUTH_BASIC} --header ${CONTENT_TYPE} -X POST https://account.lab.fiware.org/oauth2/token -d ${DATA}"
>     XAUTH_TOKEN="$(eval ${REQUEST})"
>     echo "Request: ${REQUEST}"
>     echo "X-Auth-Token for '${_user}': ${XAUTH_TOKEN}"
> }
> get_token $1 $2
> However 
> I cannot get an access token for User "Robin viewer". The message i get from Keyrock is:
> {"error": {"message": "The request you have made requires authentication.", "code": 401, "title": "Unauthorized"}}
> I assumed authorizing user "Robin viewer" for the Babbler app in the Keyrock user interface would be enough. What am i missing here?
