RE: Windows authentication - Web.Config

Hi Dave,

The configuration snippet you pasted means:

===========================
<roleManager enabled="false"/>
<authentication mode="Windows">
</authentication>
<identity impersonate="true"/>
<authorization>
<deny users="?"/>
</authorization>
============================

Your ASP.NET application is using Windows Authentication, so it no longer
use Membership Service. And the role management service is still enabled
and it use the default Rolemanger provider(ASPNETSqlRoleProvider...). When
windows authentication is used, the HttpContext.CurrentUser.Identity will
become a WindowsIdentity if the IIS did forward an authenticated windows
account to the ASP.NET application. Also, if you're using Windows
Authentication, it'll be more appropriate to use WindowsTokenRoleProvider
as configured below:

==============
<roleManager enabled="true"
defaultProvider="AspNetWindowsTokenRoleProvider" >
<providers>
================

For detailed concept on role management and authorization in ASP.NET, you
can have a look at the following MSDN references:

#Understanding Role Management
http://msdn2.microsoft.com/en-us/library/5k850zwb.aspx

#Managing Authorization Using ASP.NET Roles (Visual Studio)
http://msdn2.microsoft.com/en-us/library/53s18z5c.aspx


In addition, when using Windows Authentication, the ASP.NET will also
perform FileAuthorization checking(based on the NTFS ACL on aspx page
files);

Hope this helps.
