A call to SSPI failed? service that does not support .Net Framing? HTTP endpoint

Hii,

I have ASP.Net web application that is consuming Dynamics AX 2012 R2 inbound LedgerServices web services. 

This web app is running on IIS on the same server having AOS.

When we run the application it gives following errors..

1. A call to SSPI failed, see inner exception. 

2. You have tried to create a channel to a service that does not support .Net Framing. It is possible that you are encountering an HTTP endpoint.

Explored other posts related to this but not getting resolved. 

Please guide step by step to solved the problem.

Thanks,
