Question

Can i get the requester windows IPrincipal when he comsume WCF service?

Answer 1

Using this code, you can examine the current security context inside your WCF service.

If the user is authenticated, and the WindowsPrincipal is not null, then you’re using a Windows security model – you can access all the relevant info:

ServiceSecurityContext current = ServiceSecurityContext.Current;

if (!current.IsAnonymous && current.WindowsIdentity != null)
{
    string userName = current.WindowsIdentity.Name;
}
