iis 7.5 dns windows 身份验证页面用户身份不起作用

Question

In IIS 7.5 server I have a website apps.mydomain.com. Site binding for this website is:

IP: All Unassigned

Port: 80

Host name: apps.mydomain.com

In DNS there is an ip address pointing to apps.mydomain.com. Site comes up fine when browsing to this hostname.

I want to get current windows logged in username from asp.net web apps. I enabled windows authentication and disabled anonymous. Using this ASP.Net code to test:

Response.Write(Page.User.Identity.Name);

However, browsing to http://apps.mydomain.com/site/ the application pool identity shows as the Page.User.Identity.Name value and not the current windows logged in username.

If I browse to http://servername/site/ then Page.User.Identity.Name will return current windows logged in username.

Is there something else I need to configure to get the current windows logged in username when using host header?

web.config:

    <?xml version="1.0"?>
<configuration>
    <system.web>
        <authentication mode="Windows"/>
    </system.web>
</configuration>

Answer 1

Most likely, because the http://servername/site/ is working, it is because you are resolving to internal DNS servers, so Windows Auth kicks in for you. Have you tried explicitly setting the authentication method to 'Windows' in the web.config file?

<authentication mode="Windows" />

Answer 2

Change the app pool for the test application from "test" to ".NET 2.0 Apps" as the root of your site has different config from the test application. The windows athentication is setup correctly for ".NET 2.0 Apps" app pool but i think that dosn't effect the "test" app pool.

good luck
