Hi,

 I'm trying to integrate an ASP.NET MVC 3 application with an existing DNN website. The reason for integration is to benefit from the Single Sign On (SSO) features of the DNN website.

In order to achieve that I publish the MVC 3 app to the DNN website; as I learned in order to have SSO in DNN I need to have the new website either as an Virtual directory or Application. I did so as well.

Considering that my MVC 3 app is empty, just a "Hello World" and I want to test the SSO, I referenced the DNN HttpModule as requested.

However when I click the link to MVC app from DNN portal, I get the following errors:

[NullReferenceException: Object reference not set to an instance of an object.]
   DotNetNuke.Common.Globals.get_Status() +146
   DotNetNuke.HttpModules.RewriterUtils.OmitFromRewriteProcessing(String localPath) +158
   DotNetNuke.HttpModules.RequestFilter.RequestFilterModule.FilterRequest(Object sender, EventArgs e) +441
   System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +79
   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +164

I appreciate any thoughts.

Thanks,
Reza
 

Hi Sebastian,

 Thanks for the reply. We followed similar approach and it didn't work. I also worked on disabling the inheritance between Web.Config from DNN to MVC app which failed also.

 The solution was to state in MVC web.config to remove all the DNN modules, then everything worked fine with Single Sign On.

 Thanks,

Reza
