Hi
We are using passive claims based authentication on a load balanced app with sticky sessions enabled. We want to get rid of sticky sessions and to do this As suggested by some article on msdn site, I added this piece of code to my global.asax file to change the encryption from DPAPI to RSA.
void FederatedAuthentication_ServiceConfigurationCreated(object sender,Microsoft.IdentityModel.Web.Configuration.ServiceConfigurationCreatedEventArgs e)
{ Log.Debug("FederatedAuthentication_ServiceConfigurationCreated"); List<CookieTransform> sessionTransforms = new List<CookieTransform>(new CookieTransform[] { new DeflateCookieTransform(), new RsaEncryptionCookieTransform(e.ServiceConfiguration.ServiceCertificate), new RsaSignatureCookieTransform(e.ServiceConfiguration.ServiceCertificate) }); SessionSecurityTokenHandler sessionHandler = new SessionSecurityTokenHandler(sessionTransforms.AsReadOnly()); e.ServiceConfiguration.SecurityTokenHandlers.AddOrReplace(sessionHandler); Microsoft.IdentityModel.Web.FederatedAuthentication.WSFederationAuthenticationModule.AuthorizationFailed += WSFederationAuthenticationModule_AuthorizationFailed; }After adding this code, I receive the below error:
Server Error in '/' Application.
Value cannot be null.
