Getting Windows LoggedIn UserName in ASP.NET intranet application

Question

0.00/5 (No votes)

See more:

When an ASP.NET page loads, i want to log the windows account logged into the computer. I have tried

Environment.UserDomainName + "\" + Environment.UserName

but this returns the windows account that is HOSTING asp.net on the server.

I have also tried

System.Security.Principal.WindowsIdentity.GetCurrent

still with no success.

Will any one guide me on how to get the username of the person logged into windows when an asp.net page loads!

Solution 1

One problem with getting the user name is that you have a dependency on the configuration in IIS. If your website is set up to run with Anonymous Access only, then you will not get the user. You need to change the settings to allow Integrated Windows Authentication to retrieve the user name.

In the page, you can use Page.User.Identity.Name.

Solution 2

Have you disabled anonymous mode in IIS

Have you set the application to autheticate the user details

XML

<authentication mode="Windows"/>
<authorization>
  <allow users="*"/>
</authorization>

Have you used

HttpContext.Current.User.Identity.Name

You typed more code in there than I did;). Have a 5 from me.

@Reiss: the application requirements dictate that we stick with Forms Authentication, Will i only be able to achieve what i want to do only if i switch to Windows Authentication?. Switching from Forms to Windows authentication is really not applicable with this website application.

EricCiz - if you are using Forms authentication, then can't you just store the username entered in the form for later use?

@Reiss - but that would be the asp.net sql membership username, but for this particular requirement i need the windows username because some pages in application do not require signing in but i still want to know who was logged into windows when they loaded.
