System.ServiceModel.Security.SecurityNegotiationException in WCF RIA Service

Posted By:      Posted Date: September 12, 2010    Points: 0   Category :WCF
Good day, I created a WCF RIA service application in Visual Studio 2008. However, when I run the application it posts this exception. I set the includeExceptionDetailInFaults to true: <behaviors> <serviceBehaviors> <behavior name="serviceBehavior"> <serviceDebug includeExceptionDetailInFaults="true"/> <serviceMetadata httpGetEnabled="true"/> </behavior> </serviceBehaviors> </behaviors> However, I still get the this error in my client app..... Any idea to diagnose the issue? or any suggestion on exception handling in WCF?? Thanks in advance!!

Good Day all,

Having an issue with an outside user accessing my IIS7 box. I do not have this problem when running the website from my host machine. I found this post: Http://forums.asp.net/t/1371394.aspx. I assure you that this is not a solution because I am not storing any of my files on a network share. 

What do you think my approach should be. 

I already have read rights to IIS user to my BIN folder. 

Thanks for the help.

Windows Server 2003: Discover Improved System Info, New Kernel, Debugging, Security, and UI APIs


There's a lot to say about Windows Server 2003. First of all, it's the first operating system with built-in .NET Framework support, and it's the first 64-bit OS from Microsoft. But wait, there's more! There are lots of new features and APIs in this version as well. For instance, Windows Server 2003 features Hot Add Memory and a number of other arcane new tidbits. There are new APIs for handling threads, directories, and files, and new features like the low fragmentation heap for managing memory and system information. There's vectored exception handling and new UI APIs as well.OS internals expert Matt Pietrek takes a look at the additions he finds most interesting and useful so you'll have a good place to start when you dive into Windows Server 2003.

Windows Identity Foundation Security Token Service can't stay logged in

I'm using the Windows Identity Foundation **(WIF)** Security Token Service **(STS)** to handle authentication for my application which is working all well and good. However I can't seem to get any long running login with the STS. From my understanding I shouldn't care about the client tokens at the application level since they can expire all they want to and it should redirect me to the STS and as long as they're still logged in on the STS it should refresh their application token. Yet it doesn't seem to want to keep them signed in. Here's what occurs in my login.aspx on the STS var cookie = FormsAuthentication.GetAuthCookie(userName, persistTicket); if (persistTicket) cookie.Expires = DateTime.Now.AddDays(14); Response.Cookies.Add(cookie); var returnUrl = Request.QueryString["ReturnUrl"]; Response.Redirect(returnUrl ?? "default.aspx"); Which was taken almost directly from existing application using normal Forms Auth. From my web.config <authentication mode="Forms"> <forms loginUrl="Login.aspx" protection="All" timeout="2880" name=".STS" path="/" requireSSL="false" slidingExpiration="true" defaultUrl="default.aspx" cookieless="UseDeviceProfile" enableCrossAppRedirects="false" /> </auth

SMO System.Security.SecurityException

Hello everybody I wrote a backup procedure using smo. this procedure works great on my dev box, but once deployed to the hosting company's web server it throws above exception ("System.Security.SecurityException: That assembly does not allow partially trusted callers.") I did some research on the subject and it seems that hosting companies give you only medium trust in the config file and hence cannot access smo. My hosting admin is a great fellow (www.alsonetworks.com, recommended!) and is willing to help out, so he told me that he: A. installed smo 2008 in the GAC B. added them to the medium.config file Even so, I still receive the error. Now, I'm pretty sure he'd do anything possible to get it to work (sans giving full trust) but i'd got to tell him what to do. So can anybody advise any additional steps that can be done to get this to work? my site is built with vb asp.net 3.5 against mssql 2008, but the hosting site uses mssql 2005. I appreciate your help and advice PS. I've also read a lot about AllowPartiallyTrustedCallers, but I understand that it is irrelevant here as i have not written the assembly. it would be something ms could/should do. is that correct?   heres the code : Public Shared Sub Backup() Dim sqlCon = New SqlConnection(ConfigurationManager.ConnectionStrings("Main").ConnectionString) Dim conn As New Server

Problem with DuplexChannelFactory(System.ServiceModel.InstanceContext, System.ServiceModel.Descripti

I have derived a class from DuplexChannelFactory, and one of the constructors of the derived class takes System.ServiceModel.InstanceContext and System.ServiceModel.Description.ServiceEndpoint arguments. I simply pass them down to the base DuplexChannelFactory class, e.g.: public DerivedDuplexChannelFactory(System.ServiceModel.InstanceContext instanceContext, System.ServiceModel.Description.ServiceEndpoint endPoint) : base(instanceContext, endPoint) {} The problem I am running into that I get timeout exceptions when trying to callback the client during a service call, e.g.: Client subscribes to Service Client calls some Service method, during which call the Service will callback to the client Before I go further, if I call down to a different base constructor of DuplexChannelFactory, things work perfectly, e.g.: public DerivedDuplexChannelFactory(System.ServiceModel.InstanceContext instanceContext, System.ServiceModel.Description.ServiceEndpoint endPoint) : base(instanceContext, endPoint.Binding, endPoint.Address) {} If I use the former, I get the following exception: "This request operation sent to http://schemas.microsoft.com/2005/12/ServiceModel/Addressing/Anonymous did not receive a reply within the configured timeout (00:00:59.9820000). The time allotted to this operation may have been a portion of a longer timeout. This may be because the service is still pr
