Windows Identity Foundation (WIF) & Azure AppFabric Access Control Service (ACS) v2 - Mapping User to ASP.NET Profile In Claims Aware Applications

  • Artikel

I have captured quick steps for creating Claims Aware ASP.NET Web Site that utilize ASP.NET Profile feature.

  • Open VS 2010 in elevated mode as Administrator. Needed for WIF integration.
  • File-> New -> Web Site. Give it a name, https://localhost/ClaimsMappedToProfile.
  • Configure IIS to load user profile.
  • Click on Website, and then on ASP.NET Configuration on the menu.
  • IE should open ASP.NET Web Site Administration Tool.
  • Click on provider tab.
  • Click on Select a single provider for all site management data link
  • Click on test link next to AspNetSqlProvider. You should see Successfully established a connection to the database message. Click Ok to discard it.
  • Add the following entries to the web.config.

<profile enabled="true" defaultProvider="AspNetSqlProfileProvider">
       <providers>
             <clear/>
             <add name="AspNetSqlProfileProvider" type="System.Web.Profile.SqlProfileProvider" connectionStringName="ApplicationServices" applicationName="/"/>
       </providers>
       <properties>
             <add name="PostalCode" type="System.String"/>
       </properties>
</profile>

  • Add Textbox, Button, and Label controls to the Default.aspx page.
  • Add the following code to the page’s code behind:

string user = string.Empty;
protected void Page_Load(object sender, EventArgs e)
{
    user = User.Identity.Name;
}
protected void Button1_Click(object sender, EventArgs e)
{
    Profile.PostalCode = Server.HtmlEncode(TextBox1.Text);
}
protected override void OnPreRender(EventArgs e)
{
    base.OnPreRender(e);
    Label1.Text = Profile.PostalCode + " " + user;
}

  • Go to ACS and get WS-Federation metadata URL.
  • In Visual Studio 2010 Run FedUtil by right clicking on the project and choosing  Add STS reference…
  • Provide the WS-Federation metadata URL obtained from ACS management portal.
  • Test your work by running the application and getting authenticated by different IdP’s
  • NOTE: if you have the same name on different IdP’s – you will get the same profile data for both. If you store sensitive data in the ASP.NET profile it might introduce a security breach.
