WIF : Claims Aware Web Service exception

 

This is with the “Identity and Access Tool” / VS 2012.

When you run the sample and hit Enter, get:

Security negotiation failed because the remote party did not send back a reply in a timely manner. This may be because the underlying transport connection was aborted.

Server stack trace:
   at System.ServiceModel.Security.IssuanceTokenProviderBase`1.DoNegotiation(TimeSpan timeout)

When you click on ClaimsAwareWebService.svc in the Directory Listing, you get:

The service cannot be activated because it does not support ASP.NET compatibility. ASP.NET compatibility is enabled for this application. Turn off ASP.NET compatibility mode in the web.config or add the AspNetCompatibilityRequirements attribute to the service type with RequirementsMode setting as 'Allowed' or 'Required'.

So in the web.config, set this to “false”:

serviceHostingEnvironment aspNetCompatibilityEnabled="true"

All good!

Enjoy!
