WCF error: The caller was not authenticated by the service

Question

If you use basicHttpBinding, configure the endpoint security to "None" and transport clientCredintialType to "None."

<bindings>
    <basicHttpBinding>
        <binding name="MyBasicHttpBinding">
            <security mode="None">
                <transport clientCredentialType="None" />
            </security>
        </binding>
    </basicHttpBinding>
</bindings>
<services>
    <service behaviorConfiguration="MyServiceBehavior" name="MyService">
        <endpoint 
            binding="basicHttpBinding" 
            bindingConfiguration="MyBasicHttpBinding"
            name="basicEndPoint"    
            contract="IMyService" 
        />
</service>

Also, make sure the directory Authentication Methods in IIS to Enable Anonymous access

I got it.

If you want to use wshttpbinding, u need to add windows credentials as below.

svc.ClientCredentials.Windows.ClientCredential.UserName = "abc";
svc.ClientCredentials.Windows.ClientCredential.Password = "xxx";

thanks

Have you tried using basicHttpBinding instead of wsHttpBinding? If do not need any authentication and the Ws-* implementations are not required, you'd probably be better off with plain old basicHttpBinding. WsHttpBinding implements WS-Security for message security and authentication.

set anonymous access in your virtual directory

write following credentials to your service

ADTService.ServiceClient adtService = new ADTService.ServiceClient();
adtService.ClientCredentials.Windows.ClientCredential.UserName="windowsuseraccountname";
adtService.ClientCredentials.Windows.ClientCredential.Password="windowsuseraccountpassword";
adtService.ClientCredentials.Windows.ClientCredential.Domain="windowspcname";

after that you call your webservice methods.

If you're using a self hosted site like me, the way to avoid this problem (as described above) is to stipulate on both the host and client side that the wsHttpBinding security mode = NONE.

When creating the binding, both on the client and the host, you can use this code:

 Dim binding as System.ServiceModel.WSHttpBinding 
 binding= New System.ServiceModel.WSHttpBinding(System.ServiceModel.SecurityMode.None)

or

 System.ServiceModel.WSHttpBinding binding
 binding = new System.ServiceModel.WSHttpBinding(System.ServiceModel.SecurityMode.None);

I was able to resolve the shared issue by following below steps:

1. Go to IIS-->Sites-->Your Site-->
2. Features View Pane-->Authentication
3. Set Anonymous Authentication to Disabled
4. Set Windows Authentication to Enabled
