Challenges while we try to use the SSL Mutual Authentication with Client Certificates for WCF service hosted on IIS.

I hope this help!
In case we are working with AMSX Web Service, all above points remains same.
1. Integrated Mode.

3. Add Client Cert Mapping on the Web Site.
4. Add Authorization rule to deny Anonymous users.
