WCF / ASMX :: Read Authentication Cookie In Other Technologies Like JAVA?

Jan 12, 2011

I am having a scenario, where i need to decode ASP.NET FormsAuthentication Cookie in other language to accomplish Single Sign-On.

I am having a ASP.NET website, that also has WCF Authentication service. But I have just come know that even Java and PHP Application are also going to use my Authentication Gateway to authenticate user and so enable Single Sing-On.

I am done with the same in .NET application but to perform same in non-.NET techs, I need to decode FormsAuthentication Cookie of browser. FormsAuthentication Cookie are Encrypted so there must exist a algorithm that can decode it or a kind of dll that I can load in Java and read it.

WCF / ASMX :: Cookie Refuses To Get Set When Asking For A Cookie From Webservice

Jun 8, 2010

I'm trying to use a webservice that first expects the clients to login, to retrieve a cookie to re-use.
This is done through a login(string user, string pass) method on the webservice.

Doing this through a browser works fine, we get a cookie, and we can see the cookie via Fiddler or whatvever proxysniff thingy.

Time to do the same in ASP.Net, so we use the WSDL and generate a nice proxy class, and it works fine to call the login() method, but Never Ever does a cookie get set !

I already used the "cookiejar" technique - which means i create an instance of a CookieContainer and assign it to the proxyclass like this;

var cookies = new CookieContainer(3);

Ssl - How To Preserve Authentication For Forms Authentication Cookie

Aug 19, 2010

We have a non-SSL ASP.NET web app that allows a user to login (ASP forms authentication, inproc).

Once authenticated, we redirect their browser to an external, SSL secured page on another web site / domain altogether that we do not control.

The client is redirected back to a pre-configured url on our original http web app when done.

However, the customer is then asked to "re-login" again on our side which is undesired...

It seems the forms authentication cookie is destroyed when transitioning between HTTP and HTTPS and back again.

How can I keep the forms authentication cookie alive so that the customer does not have to re-authenticate on the round trip?

Use Forms Authentication From Java

Jan 26, 2011

We currently have a simple portal kind of functionality built based on ASP.NET Forms-based authentication. All the existing apps that make use of this authentication mechanism are ASP.NET based (and run on the same domain). So, all works fine. We have a new requirement to get some new Java-based web applications make use of the same authentication as well. All our apps are accessible over HTTPS.

Read Flash Cookie From Javascript

Oct 27, 2010

We have a flash video that was created for our project, we dont the source so we have to work around the compiled flash file. We are going to host the video on our domain and the video creates a sol cookie (flash cookie) file to store how far the user has proceeded though the video. So my plan is to access this cookie to see how far the user has progressed and then fire an event when they have finished the movie.

I have been googling for some help but haven't found to much. I have found out that its possible to do in javascript and I have found some .net sol file viewers but haven't seen any examples I can get my mind around. I have watched the traffic that gets created with fiddler and every time the next button is clicked a new request is fired with the swt file that is being accessed. I would also be happy with tracking every time one of these swt files has been accessed as well.

Adding ASMX Web Service Client In Netbeans / Java?

Jan 5, 2011

I was wondering if anything special is required to add a .NET web services to the "Services" tab in NetBeans to allow my java app to consume a .NET web service. I go and add my WSDL (simple method, 1 operation, takes a string), and I continuously get a NullReferenceError as below:

java.lang.NullPointerException
at org.netbeans.modules.websvc.saas.model.wsdl.impl.WsdlModel.getServices(WsdlModel.java:65)
at org.netbeans.modules.websvc.saas.wsdl.websvcmgr.WebServiceManager.addWebService(WebServiceManager.java:142)
at org.netbeans.modules.websvc.saas.wsdl.websvcmgr.WsdlDataManagerImpl$1.run(WsdlDataManagerImpl.java:79)
at org.openide.util.RequestProcessor$Task.run(RequestProcessor.java:1418)
[catch] at org.openide.util.RequestProcessor$Processor.run(RequestProcessor.java:1957)

Is this something common? I'm using Netbeans 6.9.1 and yes, the webservice is a stub that takes a string and displays a static message right now.

WCF / ASMX :: Invoking Java - No Access To Webservice At Dev Time

Oct 19, 2010

Here's my problem: I have an asp.net app that invokes a java/axis based webservice through a wsdl file provided by my customer. But, as i had no access to this webservice at the dev time, i've created a fake .net based webservice, with the same methods, returning some valid data, so i'd be able to test the integration interface. The problem is, when i add the service reference on my app, pointing to my fake webservice (.net), it's class has a certain name, and when i point it to my customer's wsdl file, it's class has a different name. Generated class name when i add the service reference by:

- .NET fake webservice = "TransferenciaEndpointSoapClient"
- wsdl file of the java/axis webservice = "TransferenciaEndpointClient"

I want the class i've created in my fake webservice to keep the same name of the wsdl, when i add the service reference on my app. I tried to add a "web reference" instead of a "service reference", but it did not work. I also tried to change the name of the class on the "Reference.cs" file, it works on my environment, but it doesn't when i put the generated bin on my customer's environment. I'd like to solve this without having to create a java/axis based fake webservice.

MVC Authentication Cookie Not Being Retrieved

Jun 7, 2010

I am having a hard time implementing "Remember Me" functionality in an MVC application with a custom principal. I have boiled it down to ASP.NET not retrieving the authentication cookie for me. I have included a snaphot below from Google Chrome.

Shows the results of Request.Cookies that is set within the controller action and placed in ViewData for the view to read. Notice that it is missing the .ASPXAUTH cookie Shows the results from the Chrome developer tools. You can see that .ASPXAUTH is included here.

Does anyone know what the issue may be here? Why does ASP.NET not read this value from the cookie collection?

My application uses a custom IPrincipal. BusinessPrincipalBase is a CSLA object that ust implements IPrincipal. Here is the code for that:

[Code]....

I do not think that any of this is related because the bottom line is that the Request.Cookies does not return the authentication cookie. Is it related to the size of the cookie? I heard there are issues to the size of the cookie.

UPDATE: It seems that the issue revolves around subdomains. This site was being hosted with a subdomain and the cookie domain was left blank. Does anyone have any pointers on how I can get the auth cookie to work with all domains (e.g. http://mydomain.com, http://www.mydomain.com, and http://sub.mydomain.com)?

Read And Process Data From Flash Cookie

Dec 12, 2010

I want to create a flash swf file that will store a token in Local Shared Object. What do I need to do to read that token and look it up in the database on the back end? Is this possible at all? here is a possible scenario:

User visits my web page. A token is generated on the server and stored in the database. Token is then saved in LSO. User leaves the site (maybe shuts down his computer) and comes back later. Token is read, located in the database and the user is recognized (lets say that token is a foreign key that links to other user data stored in the db). I researched this for quite a while and all I find is that flash can use LSO to store read data for flash movie. Does this mean that the data can not be accessed by the server?

Security - How To Create An Authentication Cookie

Jan 29, 2010

Do we know the algorithm that asp.net uses to create the authentication cookie (when using forms authentication?)

Can we basically create our own copy implementation? if so, how?

What does it use to generate the encrypted cookie value, I know it uses whatever you pass into the SetAuthCookie call (which is usually the userID/username).
