InfoPath 2013 Getting current user details error

Question

I have SharePoint server 2013 and a custom list I want to get current user details in InfoPaht form 2013

I followed post from: https://spvee.wordpress.com/2013/04/10/auto-populate-user-information-in-infopath-with-claims-based-authentication-part-1-of-3/

but when I preview my form I get bellow error:

The SOAP response indicates that an error occurred on the server:

Server was unable to process request. ---> Attempted to perform an  unauthorized operation.

when I open the form in browser I get bellow error:

 An error occurred while trying to connect to a Web service.


 An entry has been added to the Windows event log of the server.
