WCF WebService: Client can't connect, as soon as request client cerficate is activated.
- by Hinek
I have an .NET 3.5 WCF WebService hostet in IIS 6 and using a SSL certificate. The communication between client and server works. Then I activate "request client certificate" and the client can't connect anymore
Exception: System.ServiceModel.Security.SecurityNegotiationException: Could not establish secure channel for SSL/TLS with authority 'polizei-bv.stadt.hamburg.de'.
Inner Exception: System.Net.WebException: The request was aborted: Could not create SSL/TLS secure channel.
The certificate, the client uses is in the certificate store (local computer), the root ca is int the trusted root certification authorities store.
Where can I check for an explanation on the server side? How can I check if the client really supplies it's certificate (client is not on my side)?
