I am using JSF richfaces 3.3 on websphere server 7.x.
The problem is when
user logged in to the application using a browser window and had kept it open for more than LTPA token time out time then LTPA token expiration exception is occurring. Then page is not redirecting to the "logout" page configured. But it getting redirected to the Login page and after successful login then a weird xml page is displayed.
I understand that this is happening because on LTPA token time out when we try to access a JSF resource, as no authentication details are present page is being redirected to login page.
Then as no proper session is present Faces context is still trying to access previous session JSF tree this exception is occurring.
So Question is: How to handle this scenario of LTPA token time out in JSF richfaces3.3?
P.S.: Page is getting redirected to "logout" page on web session expiration.
Vamshi,
If the LTPA token has expired and you try to access a secured resource it will naturally take you to the login page.
That is the expected behaviour!
After you login again you go back to the page you had requested. Depending on your app, either a new HTTPSession is created or it might not even be created during this.
The application should be built to handle this. One approach could be to redirect the user to the main page of the application stating that required information is not available and that you are redirecting the user (after examining the HTTP Session for required information)

I have an existing website that I want to do a proof of concept with OAuth2 / OIDC. To this end I've configured a locally running IdentityServer4 MVC app as my demo OIDC server following the IdentityServer4 quick setup guidelines. This works fine and navigating to:
http://localhost:5000/.well-known/openid-configuration
Lets me see the discovery document.
I have created a fake login page on this OIDC app which consists of just a login button with no user credentials required.
There's no actual user database and I'm just hard coding some user details to return when the 'authentication' occurs.
In my pre-existing site I've added the OWIN middle wear and am configuring OIDC using the OpenIdConnectAuthenticationOptions. The clientId, scopes, secret etc all match as required and the authority is set to point to my locally running demo OIDC app (http://localhost:5000). The redirect url is set to return to my pre-existing site once authentication is complete.
This all appears to be fine but here's what I want to achieve and can't get working. On my pre-existing site when I navigate to any page that requires authentication I want the user to be redirected to the login page I created on OIDC app. They click the login button (no user details required) and are authenticated and redirected back to the original page.
Currently when I navigate to a protected page I am successfully redirected to the OIDC app but I am redirected to an error page and I don't know why. The error page gives me no detail, it's actually hard coded in the app.
When I look at the discovery document I see that the setting for the 'authorization_endpoint' is set to:
http://localhost:5000/connect/authorize
So I thought maybe I needed to either change that to point to Home/Login which is where I've created the dummy login form, or else I needed to actually create that connect/authorize endpoint and put my form there. Creating the end point makes no difference, it never gets hit and instead I just get the error page on my OIDC app. Changing it to home/login also appears to be ignored.
I am away from my main PC at the moment hence the lack of code snippets but essentially the set up is as per the IdentityServer4 quick setup guide and the OIDC app does appear to be working.
The issue is getting my pre-existing site to properly redirect to the login page.
I've been stuck on this for quite a while now and would like to even get to the stage of seeing the dummy login page. Any pointers are appreciated and again apologies for the lack of sample code.
UPDATE
I've got the login form appearing by setting the openidconfiguration like so:
Configuration = new OpenIdConnectConfiguration()
{
AuthorizationEndPoint = "http://localhost:5000/home/login"
}
However, this isn't logging me in when I click login. On that login action I'm doing this:
await HttpContext.SignInAsync("subjectId","username", authenticationProps);
And then redirecting back to my existing site. However it's not authenticating me and the redirect ends up being redirected back again to the login page.
UPDATE 2
I think the redirect URI should possibly be doing something more. Currently I do the following:
Try and access a restricted page -> Redirected to OIDC server -> Click Login (this sets the subject and user successfully) -> Am redirected to redirect URI which immediately bounces me back to the OIDC server.
So maybe the redirect URI is supposed to confirm login or otherwise do something?
So in the open id connect protocol, the authorize endpoint is used to validate the client information passed as query parameters (client_id, scopes, redirect_uri, etc). In your authentication server, none of that is being checked if all the endpoint does is return a form. Then again the validation can be tedious so keeping the authorize endpoint separate from the endpoint for logging in might be worth a thought.
The developers of Identity Server thought the same thing which is why they set up the endpoint (and endpoint validation) for you as part of the middleware. The validation uses the components that were injected (primarily the client_store, and your defined scopes) to be used by Identity Server.
After the framework validates your authorize request using your client store implementation, it will redirect the user to whichever login page you specify. The login page can be specified by changing it with the a delegate that can be passed in as the second parameter of 'AddIdentityServer' (that takes in something of type IdentityServerOptions that we'll refer to as just 'options'). In the delegate you can specify the login url of the page by changing the value of 'options.UserInteraction.LoginUrl' to the url of the login page.
After the user logs in and you call the signInAsync method on the HttpContext, you're actually supposed to redirect back to a query parameter passed to the login page referred to as the 'return_url' (which is basically the initial authorize endpoint request). This authorize endpoint further validates the cookie and will send the user back to the 'redirect_uri' (if consent on the client is set to false) with a code (if using the authorization code flow) or the id_token and optionally the access token (if using the implicit flow).
Assuming the implicit flow for simplicity, the tokens can be found in the request to the 'redirect_uri' and from there it's all up to you. Commonly the client will issue some kind of cookie (which can potentially contain the id or access token) to mark the successful authentication by the identity provider.
I have a problem regarding the Session Timeout handling in Spring Security in our spring application. Actually the application is configure for 1 hour session timeout in SiteMinder. So after 1 hour, the application session is timed out. After session time out if we do any operation on the page, instead of redirecting the user to invalidsession.jsp, as its configured in our security-context.xml file. Currently when we click on the submit button a search button, an ajax call is made and its giving a wrong message saying records are not found, which is confusing for the user. How to handle this issue in such a way that after session time out, instead of ajax call, the application should redirect to invalidsession.jsp
When i publish my application from my local development server to the shared hosting server i get an error the first time someone logs in.
Error in Controller Account, Action method Login. Exception: The anti-forgery cookie token and form field token do not match.
I've tried adding a machinekey but that didn't seem to make a difference. I am refreshing the login page prior to trying to login. Seems like the same issue as this
The anti-forgery cookie token and form field token do not match in MVC 4
but the machine key didn't solve it. My application is ASP.Net 4.5.1 MVC5.1
I'm using shibboleth authentication in my application, and when user clicks Logout button, he will be directed to the ~/Shibboleth.sso/Logout link, it seems like a success when button clicked, but if I try to login using shibboleth one more time, it will not redirect to the Shibboleth Login page! instead it shows the previously logged on user (that I've logged out).
So session seems to be persistent even after logout!
But if before signing in again, I closed my browser, the user is redirected normally to the Shibboleth Login page.
So it seems like a session state or cookie problem!
I've used the following code to solve it:
if (Request.Cookies["shibsession"] != null)
{
HttpCookie myCookie = new HttpCookie("shibsession");
myCookie.Expires = DateTime.Now.AddDays(-1);
Response.Cookies.Add(myCookie);
}
Response.Redirect("~/Shibboleth.sso/Logout");
But it's not working!
Can any one help?
The URL Shibboleth.sso/Logout hit at Service Provider has no control over the IdP's session, nor could it. It can send SAML logout requests, or issue proprietary redirects.
Best practice: Logout handler should be handled by Identity provider.
Closing browser is only option after doing logout. Logout doesn't work at scale and it never will unless the browser vendors cooperate and just do it themselves. So you
could assume that closing the browser is the only option and that still
requires clearing cookies on latest browsers Chrome or Firefox.
Using Spring Security preauthentication, my web app re-directs to /login_disabled.html upon hitting a InsufficientAuthenticationException.
sample of applicationContext-security-preauth.xml
<beans:property name="exceptionMappings">
<beans:props>
<beans:prop key="org.springframework.security.
InsufficientAuthenticationException">
/login_disabled.html
Based on this post, it seems that I should be able to re-direct the user to log in again.
Would I just need to re-direct the user to the webpage responsible for authentication?
It's not really clear for me what's the problem here. The redirection to the login page is automatically done without any further configuration if you have form-login set up. If the user tries to access a secured page without being authenticated, the ExceptionTranslationFilter invokes the AuthenticationEntryPoint to initiate authentication.
Using ExceptionMappingAuthenticationFailureHandler to map InsufficientAuthenticationException to a redirect-url won't work anyway because:
It's not indicating an authentication failre. It indicates the condition that the user is only anonymously authenticated while trying to access a secured resource. (As opposed to an auth failure such as entering bad credentials, or user has disabled status.)
It never even gets thrown. (Only instantiated and passed as a parameter in the above linked code.)
