.net - NLog: Log the user who called the application in a WCF application in IIS -

-

i have following scenario:

  • a deployed wcf service running windows hosted service. wcf service used log specific events database (nlog v2). service uses basichttpbinding.

  • a deployed web application (different server) under iis. application pool runs under network service credentials. web application authentication windows-integrated (active directory credentials).

whenever call wcf console application can user identity system.threading.thread.currentprincipal.identity.name; when call web application expect "domain\server$" thread identity name (which occurs expected).

my problem is: i'd user called web application. i've tried set aspnetcompatibilityrequirements attribute in wcf service contract, ${asp-application}, ${aspnet-user-identity} , ${asp-request} parameters in nlog read null. httpcontext in web application ok, not being sent wcf. there's credentials property in nlog.logger class, it's read-only.

does know how solve it?

probably, need set impersonatecallerforalloperations attribute
