Office 365 Authentication... (Error: The connection's device credentials must be specified.)

Question

Hi Everyone.

I have a problem. I am using the Simplified connection to connect to office 365.. http://msdn.microsoft.com/en-us/library/jj602970.aspx

However, I get an error "The connection's device credentials must be specified." when I run this LINQ Query.

 public string GetConfigValue(string key, IOrganizationService service)
        {
            var ocontext = new OrganizationServiceContext(service);

            var priorityMatrix = (from itil in ocontext.CreateQuery("apitil_itilsetting")
                                  where (string)itil["apitil_key"] == key
                                        && itil["apitil_key"] != null
                                        && itil["apitil_value"] != null
                                        && ((OptionSetValue)itil["statuscode"]).Value == 1

                                  select new
                                  {
                                      priorityMx = itil["apitil_value"]
                                  }

                                 ).FirstOrDefault();

            return priorityMatrix != null ? priorityMatrix.priorityMx.ToString() : null;
        }

Do I really need the device ID and device password in my app.config file? I thought the authentication of the office365 does not need this?

Are you sure that your CRM organization uses Office365 authentication?

The device credentials are required only when connect to CRM with liveid authentication

Thanks for your reply Guido.

I presume that this screenshot says it all as it says liveid as authentication type. I presume it should say office365?
