WCF Identity check failed

I keep getting this error when connecting to my web service

The identity check failed for the outgoing message. The expected identity is 'identity(http://schemas.xmlsoap.org/ws/2005/05/identity/right/possessproperty: http://schemas.xmlsoap.org/ws/2005/05/identity/claims/upn)' for the 'http://qbes:3790/Bullfrog/QBService/QBService' target endpoint.

The only time I can get it to work is if I set my identity to my email address. I don't know why this works I was just trying things and it worked. But when I publish the client app to my web server that email ide开发者_Go百科ntity no longer works and I get the same error. What am I doing wrong here? Here is my config section. Thank you!!!

Your client endpoint configuration specifies expected identity of the service. User principal name identity checks the user account used to run the service. The account has to be specified in UPN format which is indeed the same format as email: userName@domain. I expect that the service is running under your user account so that it is the reason why it works when you type your email.
