Project Overview

TopCoder is implementing a Web-based Arena by using Web Socket protocol, AngularJS Framework (http://angularjs.org, http://docs.angularjs.org/guide) and Bootstrap 3 (http://getbootstrap.com/getting-started).

The frontend application is using AngularJS Framework (http://angularjs.org, http://docs.angularjs.org/guide) and Bootstrap 3 (http://getbootstrap.com/getting-started), and using web socket protocol to exchange data with backend web socket listener.

The backend web socket listener is ready for exchanging messages over web socket protocol.

Competition Task Overview

For the previously implementation of SSO Login, it has the following problems:

1. It directly talking to database, which we are using LDAP instead.
2. It didn't properly setup user based on the roles.

For this contest, we'd like to make update for the old logic to fix the above problems.

Following are the suggested changes.

Authenticator interface and its implementations

Please remove the authenticateUser(DBServices s_dbServices,String sso) method, the login for SSO will leverage authenticateUser(DBServices s_dbServices, String username, String password, String newHandle) method.

DBServices interface and DBServicesBean

authenticateUserSSO is wrongly implemented to authenticate user against database, but the user role can not be properly set then.

So we'd like to rename the method name like validateSSOToken(String sso), and it will return the username (userId) and password, so we can do against LDAP.

CoreServices Update

For authenticateUser(String sso) method, it will get the username and password from DBServices, and then call authenticateUser(String username, String password, String newHandle) for authentication.

SSOLogin Functionality Verification

Please setup the web arena to make sure the SSO login is still working properly.

How to Setup

Please check https://github.com/cloudspokes/app/wiki/TopCoder-Competition-Engine---Build-and-Run to setup the services and https://github.com/cloudspokes/arena-web to setup the web arena for testing.

Local Setup

If you want to have a better way for debugging the problems, you can setup your own local environment, please check https://github.com/cloudspokes/app/wiki/TopCoder-Competition-Engine-Setup-on-CentOS-6.x-x64

Winner Responsibility

Winner will be responsible to create a pull request in final fix phase for merging.
