HTTP Error 404.15 – Not Found with Windows Authentication

I have the problem, that I can't use windows authentication, because I have the same problem described here: http://www.syncfusion.com/kb/5051/how-to-resolve-the-http-error-404-15-not-found
But this is no solution, because I need windows authentication. I tried windows authentication with telerik and DevExpress controls, and ths works fine.

So what is the problem?

Hi Darius,

Thanks for contacting syncfusion support,

We are unable to identify your problem from the provided information. Could you please provide answers for the following queries?

Which version of Syncfusion assemblies are you using?

Are you creating your project using Syncfusion template?

What type of application are you using?

Are you unable to run your application after adding Syncfusion MVC assemblies?

The KB article provided in our website is just one of the possible way to rectify the windows authentication error. But there may be other reasons which could be the cause of this problem. The following methods are other possible ways to resolve this error.

You can increase the maxQueryString attribute value in the <requestLimits> in <system.webServer>.

If you use form in your application, then better to remove the method attribute instead of set that value to “get”.

If still you face the problem, please provide more information regarding this, so that we could analyze and provide a solution at the earliest.

Regards,

Francis Paul A

Can't find "<requestLimits>" or "<system.webServer>" in my project.

I attached the test project

Hi Darius,
Thanks for your patience.  
We have created the Project Templates from Visual Studio 2013 only. So we are suspected that this issue occurred since the Project Templates not compatible with VS 203 update 4 since this issue occurred in Visual Studio 2013 update 4 inconsistently. So we have modified our Project Templates and you can install the new VSIX using the below steps.
1.     From your Visual Studio 2013, navigate to the Tools->Extension and Updates.
2.     Select the Syncfusion.MVC.VSPackage.Web, and uninstall by clicking the uninstall button. In case you are not able to uninstall, open the Visual Studio in the admin mode, and try to uninstall the VSIX.  
 

Figure 1: Uninstalling the Syncfusion Project Templates
 
3.     Close the Visual Studio.
4.     Download the new VSIX for the Visual Studio 2013.
5.     Run the downloaded extension by double clicking the new VSIX, and install it. 
6.     Once installed, open the Visual Studio and continue. Now, no any error message can be seen while execution.
 
Note: This fix will be included in our upcoming Service Pack release.

Thanks,
Kanimozhi.K.P.

Hi,

What if we have been developing for the last 2 months, only to deploy to our dev server to hit this issue, how do we fix it? we cannot start the project from scratch?

Regards
Andrew

Hi Andrew,

This issue occurred with Syncfusion MVC Project Templates in VisualStudio2013 Update 4 / Update 5 installed machines inconsistently. If we didn’t face this reported issue while developing the Web Application then we can deploy successfully without errors in any machine.

If we use the Syncfusion MVC Project Templates in Visual Studio 2013 Update 4 / Update 5 machines then the Requested URL length is exceeds from limit since the Syncfusion MVC templates are generated from Visual Studio 2013 only. To avoid this issue you need to comment below mentioned codes in the Startup.Auth.cs file as like in the below screenshot,



In some machines, the login page initially returns the requested URL that exceeds with maximum length while running the Syncfusion MVC Project Template projects in Visual Studio 2013 update 4 /update 5 installed machines. So, we need to comment this line in Startup.Auth.cs file. 

Note: The above commented code will not affect the Login page functionality. 

We have logged this issue and this will be fixed in our upcoming service pack release.

Thanks,
Kanimozhi.K.P.
