Custom login

Hi Peter,
To add a drop-down window, inherit from the AuthenticationStandardLogonParameters in the following manner:

Visual Basic
<NonPersistent> _  
Public Class MyStandardLogonParameters  
    Inherits AuthenticationStandardLogonParameters  
    Private objectSpace_Renamed As ObjectSpace  
    Private user_Renamed As BasicUser  
    Private availableUsers_Renamed As IList(Of BasicUser)  
    <Browsable(False)> _  
    Public ReadOnly Property AvailableUsers() As IList(Of BasicUser)  
        Get  
            If objectSpace_Renamed Is Nothing Then  
                Throw New InvalidOperationException("session")  
            End If  
            If availableUsers_Renamed Is Nothing Then  
                availableUsers_Renamed = ObjectSpace.CreateCollection(Of BasicUser)()  
            End If  
            Return availableUsers_Renamed  
        End Get  
    End Property  
    <Browsable(False)> _  
    Public Property ObjectSpace() As ObjectSpace  
        Get  
            Return objectSpace_Renamed  
        End Get  
        Set(ByVal value As ObjectSpace)  
            objectSpace_Renamed = value  
        End Set  
    End Property  
    <DataSourceProperty("AvailableUsers")> _  
    Public Property User() As BasicUser  
        Get  
            Return user_Renamed  
        End Get  
        Set(ByVal value As BasicUser)  
            user_Renamed = value  
        End Set  
    End Property  
End Class  

Also, you need to create your AuthenticationStandardLogonParameters descendant when creating your security:

Visual Basic
winApplication.Security = New SecuritySimple(GetType(BasicUser), New AuthenticationStandard(Of BasicUser, MyStandardLogonParameters)())  

See the attachment.

Marina,
I've seen your attachment but still do not completly understand how to setup.
I want an employee object (which must inherit from complexuser) which relates to a company. (1 user 1 company)
So the employee type is the one that logs on. during logon i want to display the available companies in the system (i know how to do that from your sample. However of course I do not want to see the button NEW in the popup window).
so we are authenticating Employees instead of users with roles and permissions.
After logging on I want to update an object to preserve logged in users.
can you change the sample to explain how to do this?
my 2nd question was How can we by default filter all listviews to the company related to the logged on user?
Peter

Hi Peter,
Please post separate questions in different threads. I've answered that question in the How can we by default filter all listviews to the company related to the logged on user? issue.
As for the current question, I'm still working on this issue and will post an answer as soon as possible.
Thanks,
Marina

Hi Peter,
Sorry for the delay. To hide a new button, use the ReadOnlyCollection as a container for users:

Visual Basic
<Browsable(False)> _  
Public ReadOnly Property AvailableUsers() As ReadOnlyCollection(Of BasicUser)  
    Get  
        If objectSpace_Renamed Is Nothing Then  
            Throw New InvalidOperationException("session")  
        End If  
        If availableUsers_Renamed Is Nothing Then  

            availableUsers_Renamed = ObjectSpace.CreateCollection(Of BasicUser)()  
        End If  
        Return New ReadOnlyCollection(Of BasicUser)(availableUsers_Renamed)  
    End Get  
End Property  

Also, as I see your task is rather complex and I advise that you review our AuthenticationStandard class ("C:\Program Files\Developer Express Inc\eXpressApp Framework v8.1\Sources\DevExpress.ExpressApp.Modules\DevExpress.ExpressApp.Security\AuthenticationStandard.cs" ). It might help you understand the authentication mechanism better.
Thanks,
Marina

Marina,
I came along way but not complete. I made a new module consisting of a Company Object and an Employee Object that inherits from User.
Secondly I created the customlogon class where I want to display this.
However I can not hook up the module in a new XAF Application and defining the Security in the Program.vb
I included the module

Hi,
To turn on your own classes instead of built-in ones use the WinApplication.Security property. For the ComplexSecurity, you can define a new security with 3 parameters, including the user type and authentication. Also, please review the
Security System Overview article. If this doesn't help please provide me more information on your authentication mechanism and scenario. For example, a user sees a logon window, finds his company in the drop-down editor, and then another drop-down editor is automatically populated with users from the selected company, and the user simply enters the password.
Thanks,
Marina

Hi Marina,
The link you provided did not work. I looked it up in the online help but already before but can't figure it out.
The scenario you say for example is EXACTLY what we want.
a user sees a logon window, finds his company in the drop-down editor, and then another drop-down editor is automatically populated with users from the selected company, and the user simply enters the password.
Can you alter the sample I sent you to make this work?
thanks in advance

Hi Peter,
It's a complex task and I need some time to implement it. However, I believe it's a rather useful functionality. I am working on a sample, and will post it as soon as possible. Also, we'll create a knowledge base article, or add a code snippet to our help. Please bear with us.
Thanks,
Marina

Marina,
thanks so far we are looking forward to see the solution you come up with.
Basically in every 'world class' application you need something like this.
to make the sample you also want to publish in the KB complete, maybe its nice to add a dropdown on the login form with the languages available from the model (localized) and when the user logins in and select e.g. German the thread culture is automatically set to his preference. this enables users to work e.g. in English UI eventhough they might have a German or French PC.
as you might have seen i tried to implement it as a module, so I can reuse it in all our XAF based applications (windows and web)

Hi,
I've attached a sample that helps you to implement your solution. Soon, we'll create a knowledge base. Also, please note that it's impossible to implement this functionality for the Web application yet. We have a bug (B30637) that doesn't allow it. Please track it to be notified about its status.
Thanks,
Marina
