Using Integrated Windows Authentication to access Active Directory

Hi,

My ASP.NET application should use the logged-in windows user credentials to access Active Directory. Therefore, no login is required.

I have disabled "Anonymous Access" & enabled "Integrated Windows Authentication" on the web server for my ASP.NET application. My Web.config file has the following entries:
<authentication mode="Windows" />
<identity impersonate="true"/>

Now when I run the application from within Visual Studio.NET, the application successfully runs after determining the windows user in the code using "User.Identity.Name" & I am able to access the active DirectoryEntry for that User.

However, when I navigate to this new aspx page from an existing ASP page, I am prompted to login to the domain again.

Any help will be greatly appreciated!!! Is urgent for me to solve this problem.

Thanks
