Livesite Login Component

SPrakash

Hi,

I am trying to use the existing Login Component in Livesite 3.0.2. I like to know how the user authentication will be done and how the to show different pages if the login is successful.

Whether Targeting can be done using the Login component.

Can any one help me out how to use the login component.

Thanks and Regards,
Prakash.VVS

You may need to implement your own redirect controller and execute it after login. Since component controllers are executed based on iwPreActions= query parameter, you can modify the component to execute say iwPreActions="login;redirect" so after the user logs in context.getUserSession().isLoggedIn() (or something like that) will be true. In your redirect controller you check if that is the case then redirect based on whatever info you need. To redirect you return a redirect object from the redirect controller.

Hopefully that made sense.

Thanks for the reply.

I like to know how the authentication is done in the login component. Is it based on the Development and Production profiles we create or is it through some other process.

Can you explain about the Authentication process.

There is fair amount of logic associated with the login process. The current databse connection is used to query the user then validate if the user is allowed on the given site.

While you are free to write your own controller that can do alternate form of login.

Here is the code for the controller:


package com.interwoven.livesite.runtime.controller.impl;

import java.io.IOException;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;

import com.interwoven.livesite.common.web.ForwardAction;
import com.interwoven.livesite.common.web.URLRedirectForwardAction;
import com.interwoven.livesite.p13n.LoginUtils;
import com.interwoven.livesite.runtime.RequestContext;
import com.interwoven.livesite.runtime.UserSession;

public class LoginController
{
  /** the logger */
  private static final Log LOGGER = LogFactory.getLog(LoginController.class);

  /** URL redirect parameter */
  public static final String REDIRECT_LOGIN_SUCCESS_URL = "LoginSuccessUrl";

  /** URL redirect parameter */
  public static final String REDIRECT_LOGIN_FAIL_URL = "LoginFailUrl";

  /** URL redirect parameter */
  public static final String REDIRECT_LOGOUT_URL = "LogoutUrl";

  /**
   * Login the user and redirect if valid
   *   do not redirect if login invalid
   * 
   * @param context runtime context
   * @return forward action 
   * @throws IOException write exception
   */
  public ForwardAction login(RequestContext context) throws IOException
  {
 //a_Already logged in or authenticated
 ForwardAction faction = null;
 UserSession session = context.getSession();

 //a_Authenticate
 if ((null != session && session.isLoggedIn()) || LoginUtils.authenticateUser(context))
 {
   //a_Find the page that the user came from
   String redirectUrl = context.getRedirectUrl();
   if (null == redirectUrl || 0 == redirectUrl.length())
   {
  //a_No redirect page in session, try to get override in component's controller
  redirectUrl = context.getLoginUrl();
   }

   //a_If redirect page found, then redirect
   if (null != redirectUrl && redirectUrl.length() > 0)
   {
  if (LOGGER.isDebugEnabled())
  {
    LOGGER.debug(
   "Login successful, forwarding: user="
   +context.getParameterString(LoginUtils.PARAM_USERNAME, "null")
   +"  password(SHA1)="
   +context.getParameterString(LoginUtils.PARAM_PASSWORD, "null")
    );
  }
  faction = new URLRedirectForwardAction(context, redirectUrl);
  context.setRedirectUrl(null);
   }
 }
 else
 {
   String redirectUrl = context.getParameterString(REDIRECT_LOGIN_FAIL_URL);
   if (null != redirectUrl && redirectUrl.length() > 0)
   {
  if (LOGGER.isDebugEnabled())
  {
    LOGGER.debug(
   "Login failed, forwarding: user="
   +context.getParameterString(LoginUtils.PARAM_USERNAME, "null")
   +"  password(SHA1)="
   +context.getParameterString(LoginUtils.PARAM_PASSWORD, "null")
    );
  }
  faction = new URLRedirectForwardAction(context, redirectUrl);
  context.setRedirectUrl(null);
   }
 }
 return faction;
  }

  /**
   * Logout the user and redirect
   * 
   * @param context runtime context
   * @return forward action 
   * @throws IOException write exception
   */
  public ForwardAction logout(RequestContext context) throws IOException
  {
 String redirectUrl = context.getLogoutUrl();
 if (context.getSession().isLoggedIn())
 {
   LoginUtils.logout(context);
 }

 //a_Redirect somewhere else if URL parameter specified
 ForwardAction faction = null;
 if (null != redirectUrl && redirectUrl.length() > 0)
 {
   faction = new URLRedirectForwardAction(context, redirectUrl);
 }
 return faction;
  }
}

Hi,
The authentication of users can be done against an LDAP or a Database server whichever you want to use. For OOTB features, you just have to specify the connection parameters in the "default.site" of the current site implementing the login component.

SPrakash

Thanks for the reply.

I like to know how to redirect the page using the above controller class.

Can you tell me where the LoginURL and LogoutURL specified in the above example come from.

Thanks and Regards,
Prakash.VVS

rajivgupta

For redirecting to a particular url after login you have to implement "AuthNavigationIfc" class and with the help of the "getNextPage" method you can redirect to whatever page you want .
For aunthentication you can configure it to use LDAP for which settings are there in default.site otherwise you can write your own custom logic to authenticate a user.

SPrakash

Thanks for the reply.

The method getNextPage in the class AuthNavigationIfc is deprecated in 3.0.2.

Can you help me which method i need to call for redirecting the page.

Thanks and Regards,

Look at the Login.component it specifies the redirect URLs.

I have returned a URLRedirectForwardAction but my page is jsut forwarding, and not redirecting. How can i get the page to redirect? i.e. show the new URL in the browser.

you should use Http302ForwardAction as the URLRedirectForwardAction is deprecated. the 302 will issue a client 302 redirect. but not sure if this will cause the browser url to update.

you might want to test wit fire bug and see what the comms are
