When we try to enable Claims Based Authentication we are unable to access CRM and see the following error on the CRM server;
Source: ASP.NET 4.0.30319.0
Event ID: 1309
Event code: 3005
Exception type: InvalidOperationException
Exception message: ID5002: The Issuer property on the FederatedPassiveSignIn control must be set to the address of an STS endpoint that can process WS-Federation passive protocol messages.
Can anyone suggest what the cause of this error is please?
Thanks.
