获取用户名asp.net Windows身份验证

Question

SO i made a simple web form, set in windows auth in iis. then i deployed it on my server and i try to log in. it prompts me a login box, i enter my infos, looks likes its working fine with active directory.

if i enter something wrong it wont work etc.

obviously i need to know who is the logged on user

Response.Write(HttpContext.Current.User.Identity.Name.ToString());

i found this in other threads, but it wont work for me...

how do i get the info filled in the login box ?

Answer 1

If you using asp.net membership provider you can get the current logged user

System.Security.Principal.WindowsIdentity.GetCurrent().Name.ToString();

User.Identity.IsAuthenticated  

can be used to identify whether user successfully logged in or not

Answer 2

<identity impersonate="true" /> in web config , fixed my problem.
