security policy export failed. the binding contains a transportsecuritybindingelement
After having a fresh installation of SharePoint 2010 i was facing the following error in my Security Token Service. I tired multiple solutions but could not fix my issue. Finally a thread helped me out to solve my problem. Note: This solution worked for me. I had a fresh installation of SharePoint 2010 without SP1 and any update. It was completely OOB. If one tries to visit standard web service such as SecurityTokenServiceApplication ( http://localhost:32843/SecurityTokenServiceApplication/SecurityToken.svc , or https://localhost:32844/SecurityTokenServiceApplication/SecurityToken.svc ), the service will respond with System.InvalidOperationException Error: Security policy export failed. The binding contains a TransportSecurityBindingElement but no transport binding element that implements ITransportTokenAssertionProvider. Policy export for such a binding is not supported. Make sure the transport binding element in the binding implements the ITransportTokenAssertionProvi
