The AuthenticationServiceManager object that is returned by this property represents the authentication service that is registered with the page. The authentication service can be defined in the ScriptManager control or in an associated ScriptManagerProxy control.
You can use the ASP.NET authentication service or use a custom authentication service. You can add the custom service in markup by including an AuthenticationService element inside the asp:ScriptManager element on the page, as shown in the following example.
<asp:ScriptManager ID="SM1" runat="server"> <AuthenticationService Path="MyAuthenticationService.asmx" /> </asp:ScriptManager>
