Credentials passing between two WCF windows Services

Question

Hi All,

I have 2 windows based services. Lets asume Service-A and Service-B.

Service-A internally calls Service-B. But all users uses Service-A. Service-A provides response based on called user (based on windows account). At the same time Service-B also provides the response based on called user.

Now my querry is, how can I pass called user credentials to Service-B from Service-A. Currently I am using below code to pass client creditials from one servie to another service. But its not working. Let me know if you have any idea.

this.serviceobj.ClientCredentials.Windows.ClientCredential = OperationContext.Current.ServiceSecurityContext.PrimaryIdentity as System.Net.NetworkCredential;

Answer 1

Add this to your method implementation:

[OperationBehavior(Impersonation = ImpersonationOption.Required)]

This will impersonate the caller fron Service A to Service B

Or

Add this to your service behavior:

<serviceAuthorization impersonateCallerForAllOperations="true" />

What i'm talking about comes from this article:
