Question:
Access SCIM API - Keyrock Fiware

Description:
I am using a fiware-idm image in a docker container (https://hub.docker.com/r/fiware/idm/) and I'm trying access the SCIM API. There is user "idm" (default user), he's provider and has all permissions. But when I try get all users:

private String getAccessToken() {
HttpServletRequest httpServletRequest = (HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();
HttpSession session = httpServletRequest.getSession();
String accessToken = (String) session.getAttribute("access_token");
return accessToken;
}

public void getUsers() throws IOException {
String accessToken = getAccessToken();

Client client = ClientBuilder.newClient();
Response response = client.target("http://192.168.99.100:5000/v3/projects")
.request(MediaType.TEXT_PLAIN_TYPE)
.header("X-Auth-token", accessToken)
.get();

setResultUsersList("-- status: " + response.getStatus() + " <br>"
+ "-- headers: " + response.getHeaders() + " <br>"
+ "-- body: " + response.readEntity(String.class) + " <br>"
+ "-- token: " + accessToken);
}

I receive an error msg:
{"error": {"message": "The request you have made requires authentication.", "code": 401, "title": "Unauthorized"}}

But the authentication works and get the user infos too:

public void authenticateUser() throws OAuthSystemException, IOException {
HttpServletResponse httpServletResponse = (HttpServletResponse) FacesContext.getCurrentInstance().getExternalContext().getResponse();

OAuthClientRequest codeRequest = OAuthClientRequest
.authorizationLocation("http://192.168.99.100:8000/oauth2/authorize")
.setParameter("response_type", "code")
.setClientId(CLIENT_ID)
.setRedirectURI("http://localhost:8080/Example-Application-Security-UI/auth")
.buildQueryMessage();

httpServletResponse.sendRedirect(codeRequest.getLocationUri());
}

public void requestUserInfo() {
HttpServletRequest httpServletRequest = (HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();
HttpSession session = httpServletRequest.getSession();
accessToken = (String) session.getAttribute("access_token");

String strJson = callWebservice("http://192.168.99.100:8000/user?access_token=" + accessToken);
JSONObject jsonObject = new JSONObject(strJson);
resultUserInfo = jsonObject.toString();
}
