The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Get Username in ASP.NET site using Windows Integrated Authentication

Asked by ideamatics in Microsoft IIS Web Server, .Net Application Servers, Programming for ASP.NET

Tags: ASP.NET, Windows, IIS

I have developed an ASP.NET 3.5 web application which is hosted on Windows 2003 Server using IIS 6.  In my application, I need to get the user name of the person accessing the site.  In IIS, I have the site configured so that it does not use Anonymous access and the Windows Integrated checkbox is checked.  So when the user enters the site, they enter their credentials.  great.  But I cannot seem to extract the user name.  I have read many posts and tried many methods, but can't seem to get it.  Take a look at the screenshot to see all the different methods I tried.  

Label1.Text = Request.ServerVariables("Auth_User")
        Label2.Text = System.Web.HttpContext.Current.Request.LogonUserIdentity.Name
        Label3.Text = HttpContext.Current.User.Identity.Name.ToString()
        Label4.Text = Request.ServerVariables("LOGON_USER")
        Label5.Text = System.Security.Principal.WindowsIdentity.GetCurrent.Name.Replace("\", "/")
        Label6.Text = Request.Form("userName")

they all result in empty strings.  Any ideas?  Please note that this site is configured with a certificate (https).  In my web.config, I have impersonate="true" in the identity tag.  I also have Authentication mode="Windows".  All ideas welcome!  Thanks
