The default process when authenticating user on OpenAM/OpenSSO works with a 302 http redirection, opening OpenAM/OpenSSO authentication formular. The original URL is stored into "goto" parameter, which allows OpenAM/OpenSSO to redirect the user back on orignal URL after correct authentication.
This works well when using HTTP GET method (i.e. when entering URL), but it is not suitable for POST method. For instance, if the session expires while the user posts a HTML form, the data are lost because HTML form inputs are not present in goto parameter.
Do you know it it is possible to configure J2EE Agent in order it re-posts user HTML form after valid authentication ?
Both the Java EE and the Web agents support post data preservation, see the documentation.

I am attempting to Login to my app with JMeter Script.
I have Cookie Manager and a Cache Manager added
My Thread Group script
GET on main login page (/app) to return session id and form fields
and cookie
POST of completed form fields with cookie (/posthandler) with "follow redirects
What happens is
POST sends initial cookie (from GET) and form fields and logs in ok
the session is established (I see a record in our app database)
the response is a redirect with a new cookie
JMeter redirects (GET) to the session url (/app?session=xxxxx)
this goes with "[no cookies]" (according to request panel)
As that request arrives without the new cookies - the app issues a second redirect back to the login page.
So is there a way to force the GET Redirect after the POST response to send the cookie?
My theory is that JMeter is that, because of the different URI path for the POST and redirect GET, JMeter is not sending the cookie.
I have tried
various Cookie Manager settings (standard, default, compatibility).
followed this Understanding and Using JMeter Cookie Manager and set check.cookies=false.
and advice SO - JMeter: Login flow involving URL redirection not working including making sure there was an init
My problem was self-inflicted !
I was running against a different environment than usual which had a different context root e.g. /test/app rather than /app. For this I amended my ${Domain} User parameter with "my.domain.com/test" rather than adjust all the Path settings.
For requests sent this approach appeared to work as the ${Domain}+${Path} resolved to the correct URL - but the Cookies created by the server were for ${Path} (as in /test/app) and JMeter was seeing this differently (as in /app).
I have now introduced a ${CtxRoot} User variable (set to /test/) and prepended this to all my Path values - and my Login is now working.
I am trying to record a simple login and logout flow for a .Net application. After I submit the login credentials the welcome page's URL has a large alpha numeric number. This number is required to continue to the next steps.
On Fiddler I have noticed that the login credential submission request results in a 302 response and this response contain an a=129characterstring that i need in my subsequent requests.
On JMeter I have added a recording controller and on the HTTP(S) Test Script Recorder I have Follow Redirects and Use KeepAlive checked (See below screenshot)
I have also recorded with Follow Redirects unchecked and different options for Grouping and HTTP Sampler Settings.
But with none of them I am able to record/capture the 302 response that i see on fiddler. Instead the login credential submission request always returns a 200 response, even if the login fails.
It is not as if that JMeter is not recording redirect requests, further down the scenario flow I have another redirect request which is captured.
I can't be the only one who is/has faced this problem. Does anyone have any suggestions on what I should be doing differently to get the 302 response?
To do this:
Record with default options, the redirect Http Request triggered by 302 will be disabled by default.
Then you will need after this to uncheck "Follow Redirect" in the first one, and add a Regular Expression Post Processor to extract the data you want.
Then enable the commented second request and inject the extracted variable.
Consider this example for authentication from PHP at https://developers.soundcloud.com/docs/api/guide#authentication seem to suggest you can pass a redirect url as a parameter when you flow a user throught the authentication process:
require_once 'Services/Soundcloud.php';
// create client object with app credentials
$client = new Services_Soundcloud(
'CLIENT_ID', 'CLIENT_SECRET', 'REDIRECT_URL');
// redirect user to authorize URL
header("Location: " . $client->getAuthorizeUrl());
Note the 'REDIRECT_URL' argument in the call to the constructor.
That seems to suggest I can pass an arbitrary redirect url as a parameter, just like you can do with Twitter (the API is quite similar).
However, if I pass an url that does not match the unique redirect url configured for the application, I get an error when the user is redirected to my url:
error=redirect_uri_mismatch&error_description=The+redirection+URI+provided+does+not+match+a+pre-registered+value.
So, what is that parameter supposed to be for, if the only valid value is the redirect url configured for the application?
And how are you supposed to handle authentication if the user can only be redirected to a single fixed url after authentication?? That makes the API completely unusable. When you have a user login into any API (e.g. Twitter or Facebook), you need them to be returned to the page from which they clicked the link to log in, and it is a ridiculous restriction that that url be unique. No other social network api that I've ever seen has this restriction.
Is SoundCloud API really so flawed or am I missing something?
I got an answer from Glen Scott, the author of the php-soundcloud library (a pretty decent wrapper around this terrible API) who provides a workaround. It's painful as it involves an additional redirect but it's all the API allows.
https://github.com/mptre/php-soundcloud/issues/36
I quote:
The API does not allow an arbitrary URL. As you noted, this is unlike
most other oAuth-backed social network API's. The workaround I can
recommend is using the state parameter to pass back your return URL.
You can do this when generating the authorization URL like this:
$client->getAuthorizeUrl(
array(
'state' => 'http://example.com/return'
) You'll get the state parameter added to the static redirect URL. For example, if you set your redirect URL to
http://example.com/callback then SoundCloud will redirect an
authenticated user to
http://example.com/callback?state=http://example.com/return
Your callback script will need to look for the state GET parameter,
and redirect using it.
I'm using FB.login on the JS client and want to verify the user's identity on the server. So, the client gets a signedRequest from facebook and sends it to the server. The server splits on the period, and decodes the second part of the signedRequest into a json object.
What should I be using for "code" when I send my server-side request to
https://graph.facebook.com/oauth/access_token?
client_id=YOUR_APP_ID
&redirect_uri=YOUR_REDIRECT_URI
&client_secret=YOUR_APP_SECRET
&code=CODE_GENERATED_BY_FACEBOOK
My decoded json looks something like:
{"algorithm":"HMAC-SHA256","code":"2.AQCPA_yfx4JHpufjP.3600.1335646800.1-5702286|l11asGeDQTMo3MrMx3SC0PksALj6g","issued_at":1335642445,"user_id":"5232286"}
Is that the code I need? Does it need to be B64 encoded? If this isn't the code, what code should I use?
_
What I've tried:
The request I'm trying to use is:
https://graph.facebook.com/oauth/access_token?client_id=295410083869479&redirect_uri=https://squaredme.appspot.com/facebookredirect&client_secret=44f1TOPSECRETbb8e&code=2.AQCPA_yfx4JHpufjP.3600.1335646800.1-5702286|l11asGeDQTMo3MrMx3SC0PksALj6g
but this returns the error:
{"error":{"message":"Error validating verification code.","type":"OAuthException","code":100}}
I can't tell if this is because I'm using a bad code, or what. Noteably, this is running on my local dev server, and squaredme.appspot.com definitely does NOT resolve to my IP. I don't know if facebook checks that or what - I'm assuming I'd get a better error message. Thanks for any direction!
You are trying to somehow combine the two flows together and that's why things don't work well.
When facebook POSTs into the iframe with your app url and a signed request there are two options, the easy one being that the user is already authenticated and then the signed request will have all the necessary data (including a signed request), then you just load the canvas page and use the JS SDK to get an access token there as well, but in this case there's no need to use the FB.login (since it opens a popup and will automatically close it), you can use the FB.getLoginStatus method which won't annoy the user.
If the user is not authenticated then the sign request will be missing the things you need to use the graph api.
You then redirect the user to the auth dialog, and since you are loaded in an iframe you'll need to return a html response which redirects the parent window using javascript, like:
top.location.href = "AUTH_DIALOG_URL";
When the use is done (accepted or rejected the app) he will be redirected to the "redirect_uri" you added as a parameter to the auth dialog.
If the user accepted your app then you'll be getting the "code" parameter in the query string.
You then take the code, exchange it with an access token as you posted in your question, and then redirect the user back to "apps.facebook.com/YOUR_APP".
When the page then loads the user is already authenticated and you'll be getting a full signed request.
I hope this clarifies things for you, recheck the Server-Side flow it pretty much covers it all.
I also had some trouble with that, then I found the solution here in StackOverflow.
There are two kinds of "code" provided by facebook. One comes inside the signedRequest in the cookie generated by the client-side flow. The Facebook's JS SDK handles this codes and get a access token without telling us anything.
The other type of code comes attached as a query to your redirect URI (http://www.yoururl.com/index.php?code=AAAgyiaus...), when you navigate to OAuth URL (server-side flow). With this code, you go to a Token URL and get your access token.
When you are using the server-side flow, you need to indicate a redirect URI both in the OAuth URL AND in the Token URL, and they have to be exactly the same, so a missing slash or a query string can be a lot of problem.
The codes are different from each other. When you use the both things together, appears to be impossible to get a access token using the code that was inside the cookie's signedRequest.
BUT, it is not. The magic is: the code from signedRequest is associated with NO URI, so as long as the redirect_uri is a mandatory field, all you have to do is to pass it blank when you navigate to the Token URL.
So the final solution is: grab the signedRequest from the cookie, parse it in your server to obtain the code, then read the Token URL:
https://graph.facebook.com/oauth/access_token?
client_id=YOUR_APP_ID
&redirect_uri=&client_secret=YOUR_APP_SECRET
&code=CODE_INSIDE_THE_SIGNED_REQUEST
It looks like a hack, so I don't know how long it's gonna work, but it's working right now.
Is there a way to go to a url without redirecting to it? Basically I want to call a url from within my application in the background so it can logout a reliant party.
Appreciate the help.
What you are trying to do does not compete us to answer as it's directly related to your own Authentication implementation.
A normal ASP.NET Authentication based in Forms Authentication you will need always to lunch the url from a browser as it is there that relies the Authentication given.
You can give yourself a try by opening your website and log in into it, after that, open other browser brand (not browser window) into your application url... you will see that you also need to login again as the Authentication is hook up into the first browser.
It's Up to you as Application Architect to make this by implementing another way of authentication, normally in this kind'a cases, this happend when consuming web services where you need a authentication code first (given by calling a Login method) and that code is always needed to be appended to the body or header of any call to the system.
This way you can easily remove the authentication code and all procedure calls will fail.
As said, this is not up to us, it's up to you to create the correct Authentication Layer.
from your comment
it's as simple as using WebClient object
WebClient client = new WebClient ();
string reply = client.DownloadString (address);
If you wish to transfer to a new url request you can still use
Server.TransferRequest()
The problem with this is that by not using a redirect the browsers address bar will not reflect the fact that you have moved their request to another URL.
To have the client visit a given URL in the background you should either make an AJAX call to it or possibly have an image with an src of your logout url (though you'd have to make sure that you return a FileResult of your image too). This is how most analytics packages call to their relevant urls in the background.
The problem here though is that neither is 100% reliable, turn off javascript or images on your browser and these results fail.
From what you've said I think what you're after is for a user to continue to any of a variety of pages rather than a specific logout page. If this is indeed the case your best solution is in fact a double redirect.
Have your application redirect to your logout url but before hand put the url of the page you want them to go to into tempdata. Then in the actionresult for the logout page you can do your logging out as required and return a redirect to the url from tempdata.
