Windows authentication & Roles within multiple Active Directories

Posted By:      Posted Date: September 23, 2010    Points: 0   Category :ASP.Net


I am struggling to set up a web site which sits in multiple domains.

I have two AD domains - Main and Secondary.

My site is configured as below.


<authentication mode="Windows"/>
  <identity impersonate="false"/>
  <roleManager enabled="true" defaultProvider="AspNetWindowsTokenRoleProvider"/>
   <allow users="*"/>
   <deny users="?"/>


<location path="Default.aspx">
    <allow roles="Secondary\All Staff,Main\Site-Editor"/>
    <deny users="?"/>
    <deny users="*"/>

<location path="Edit.aspx">
    <allow roles="Main\Site-Editor"/>
    <deny users="?"/>

Multiple Windows Authentication options on login after Web App restore

Hi I have a question regarding SharePoint Foundation 2010 and backup / restore jobs... I'm doing nightly farm backups using PowerShell: Add-PsSnapin Microsoft.SharePoint.PowerShell Set-location $home Backup-SPFarm -Directory \\same-server\***** -BackupMethod Differential This morning I decided to try and restore a single web application, just to make sure it works. In Central Administration I selected the latest farm backup and then selected the node for the Web Application and choose restore (using option: Same configuration) because it's the same server. Restore process went fine, no failure messages, and I can see that it has restored the content I deleted for testing. BUT when I enter the site. I'm presented with a Login page (that you would see if you have also configured Forms Authentication for the same zone, which I have not) and the drop down box show two options: "Windows Authentication" and "Windows Authentication". Both let me use windows credentials to login so basically the login page is pointless and it wasn't there before. I should note: The Web Application was and is configured to use Claims Based Authentication and for Windows Authentication: Kerberos. Nothing for forms. Default sign in page. And I was never presented with this redundant login page before the restore. Anyone knows why this could be happening and how to solve it?? Than

Using Active Directory Authentication when Windows Authentication fails


I have a web application (intranet based) which uses Windows Authentication.  Unfortunately there are public computers that have public logins at some company locations.  My web app doesn't support these public logins because I need to know the user working with the app.

So, even though these public users are windows authentication users, my app will fail because I have no user account setup for that particular account.  I want to then try Active Directory Authentication.

In my Default.aspx.cs I'd have something like this:

  protected void Page_Load(object sender, EventArgs e)
    userContext = new UserContext(); // If the authenticated user isn't a user in my system then throw an exception
   catch (UILayerException)
          // This I where I want to now do Active Directory Authentication
          // Maybe I redirect to a login page or what?
          // But remember the user IS authenticated even if they aren't a user in my system so I need to do something about that.

ASP.NET forms authentication with roles

.A timeout is specified in minutes. This is "time since last request" not the "time since login". If a login is indicated to be persistent (described later) this is ignored.
.A protection method is specified for the cookie.
Next I wanted to specify a folder to which access is restricted to people who have logged in. To do this I entered the following code in the web.config file (beneath

Web Matrix + Windows Authentication


I'm curious if its possible to get windows auth working with asp.net webpages/webmatrix.

I've got it published to IIS with windows auth turned on and anonymous/forms/basic turned off.

I'm guessing the WebSecurity Helper probably won't work here but can you access User.Identity.Name etc?

Sorry for the newbie questions, I've only just started working with asp.net ^^,

Using windows authentication to access SQL when using ASP.NET 4.0 via COM+


I am using SQL Server 2008 under windows authentication, front end is ASP.NET which uses COM+ to access database.

COM+ components are configured to run as domain user.

When looking through the logs (SQL Profiler), I can see the login name as the configured identity instead of windows indentity.

I have got Website running under "Intergrated Windows Authentication" and database is running locally on webserver.

Web configure contains entry for <identity impersonate="true"/>.

My connection string is

connectionString="data source=db01\test01;initial catalog=test; integrated security=SSPI;persist security info=False; Trusted_Connection=Yes"

Any ideas?




Windows Forms: Give Your .NET-based Application a Fast and Responsive UI with Multiple Threads


If your application performs any non-UI processing on the thread that controls the user interface, it may make the app seem slow and sluggish, frustrating users. But writing multithreaded apps for Windows has long been restricted to C++ developers. Now with the .NET Framework, you can take advantage of multiple threads in C# to control the flow of instructions in your programs and isolate the UI thread for a fast and snappy user interface. This article shows you how. Also, it discusses the pitfalls of multiple threads and presents a framework for safe concurrent thread execution.

Forms based users being prompted for windows authentication login for My Sites photos in user lists

Here's an issue I didn't see coming for our forms based authentication users. 

We have a web application extended to an external url to handle forms based authentication for users outside of our domain. Our setup looks like this...

Internal Users/Windows Authentication - moss.domain.com
External Users/Forms Based - mossext.domain.com
My Site for Internal Users - mysites.domain.com

When our forms based users are accessing user lists, or discussion pages that display user pictures, they are getting a windows authentication login for our internal users (mysites.domain.com) who have populated their my site with personal photo.

How do we fix this?
