Public Class SecurityStrategyComplex

    Implements ISecurityComplex,

               IRoleTypeProvider

Remarks

In the SecurityStrategyComplex security strategy, each user can belong to one or more groups. These groups are called Roles (see XPO PermissionPolicyRole or EF PermissionPolicyRole). Roles are characterized by an associated permission set. An application administrator creates users and roles, and assigns roles to users. An application developer can create a set of predefined users and roles that can be extended later by an administrator (see Client-Side Security (2-Tier Architecture)).

By default, a newly created XAF application uses no security. To enable to the SecurityStrategyComplex security strategy, invoke the Application Designer and drag the SecurityStrategyComplex component from the ToolBox's DX.19.2: XAF Security page to the designer's Security pane.

You can specify a custom user and role type by changing the SecurityStrategy.UserType and SecurityStrategyComplex.RoleType values in the Properties window.

Then, specify the authentication type that will accompany the security strategy. Drag either the AuthenticationStandard or AuthenticationActiveDirectory component from the toolbox to the Security pane of the designer. You can also use a custom authentication (see How to: Use Custom Logon Parameters and Authentication).

Alternatively, you can enable the SecurityStrategyComplex Security Strategy in code. It is required to instantiate the SecurityStrategyComplex class and assign this instance to the XafApplication.Security property. In a Windows Forms application project, modify the Program.cs (Program.vb) file in the following manner.

public static void Main(string[] arguments) {
    MySolutionWinApplication winApplication = new MySolutionWinApplication();
    winApplication.Security = 
        new SecurityStrategyComplex(typeof(PermissionPolicyUser), typeof(PermissionPolicyRole), 
            new AuthenticationStandard());
    // ...
}

Public Shared Sub Main(ByVal arguments() As String)
    Dim winApplication As New MySolutionWinApplication()
    winApplication.Security = _
    New SecurityStrategyComplex( _
    GetType(PermissionPolicyUser), GetType(PermissionPolicyRole), New AuthenticationStandard())
    ' ...
End Sub

In an ASP.NET application project, modify the Global.asax.cs (Global.asax.vb) file in the following manner.

protected void Session_Start(Object sender, EventArgs e) {
    WebApplication.SetInstance(Session, new MySolutionAspNetApplication());
    WebApplication.Instance.Security = 
       new SecurityStrategyComplex(typeof(PermissionPolicyUser), typeof(PermissionPolicyRole), 
            new AuthenticationStandard());

    // ...
}

Protected Sub Session_Start(ByVal sender As Object, ByVal e As EventArgs)
    WebApplication.SetInstance(Session, New MySolutionAspNetApplication())
    WebApplication.Instance.Security = _
    New SecurityStrategyComplex( _
    GetType(PermissionPolicyUser), GetType(PermissionPolicyRole), New AuthenticationStandard())
    ' ...
End Sub

As a result, in a WinForms application you can see the User, Role and My Details navigation items. The active user name is displayed in the status bar.
