package com.mvnforum.auth;

import javax.servlet.http.HttpServletRequest;

 * #@todo Expand guide about the overall authentication process
 * If the user is authenticated, then the memberID equals 0
 * See ForumUserServlet#process : uncomment the comment code for the hint
public interface Authenticator {

     * This method will be called by mvnForum's authentication system
     *   to authenticate the customized user
     * With this generic interface, developer could integrate their own
     *   authentication to the mvnForum system
     * NOTE: The user should already be in the Member table of mvnForum database
     *       Developer could use this implementation strategy if the user's
     *       information is in other place (such as LDAP):
     *       - Check if user is login
     *       - If no, then return null
     *       - If yes, check if user is in the mvnForum's mvnforumMember
     *          - If yes, return the username
     *          - If no, create the user
     * If you are successful, shareing your knowledge and experience to other
     * members of mvnForum community is highly appreciated
     * @see OnlineUserManager#setAuthenticator(Authenticator)
     * @param request the servlet request
     * @return the username of the current user associated with this request
     *         If no user has been authenticated in this request, then null should be return
    public String getRemoteUser(HttpServletRequest request);
