TFS: how to find checked out files in different workspace

 

My machine crashed and I wanted to find which files were checked out by me on that machine.
It wasn’t obvious, but finally I found, that I can search for user.

WCF: Suppress authentication for testing on different domain.

I have a WCF service and client, which worked fine, when I debug it on my local machine.

However when I deployed the service to test server on the different domain.


I’ve started to receive error

System.ServiceModel.Security.SecurityNegotiationException: The caller was not authenticated by the service. —> System.ServiceModel.FaultException: The request for security token could not be satisfied because authentication failed.

I’ve found a few similar recommendations, e.g.
<wsHttpBinding>
                <binding name=”CustomBinding”>
                    <security mode=”None”>
                        <message establishSecurityContext=”false”/>
                        <transport clientCredentialType=”None”/>
                    </security>
                </binding>
            </wsHttpBinding>
 
 
Unfortunately, it didn’t work for me.
Fortunately, after I’ve replaced wsHttpBinding  to basicHttpBinding , my client is able to access the server.
