IAuthenticationModule.CanPreAuthenticate Property

Gets a value indicating whether the authentication module supports preauthentication.

Namespace:  System.Net
Assembly:  System (in System.dll)

'Declaration
ReadOnly Property CanPreAuthenticate As Boolean

Property Value

Type: System.Boolean
true if the authorization module supports preauthentication; otherwise false.

The CanPreAuthenticate property is set to true to indicate that the authentication module can respond with a valid Authorization instance when the PreAuthenticate method is called.

Notes to Implementers

This is typically a fixed value; either the authentication module can preauthenticate, or it cannot.

The following example shows how to use the CanPreAuthenticate property. For a complete example refer to the AuthenticationManager class.


      Private m_authenticationType As String
      Private m_canPreAuthenticate As Boolean


      ' The CustomBasic constructor initializes the properties of the customized 
      ' authentication.
      Public Sub New()
        m_authenticationType = "Basic"
        m_canPreAuthenticate = False
      End Sub 'New

      ' Define the authentication type. This type is then used to identify this
      ' custom authentication module. The default is set to Basic.

      Public ReadOnly Property AuthenticationType() As String _
       Implements IAuthenticationModule.AuthenticationType

        Get
          Return m_authenticationType
        End Get
      End Property

      ' Define the pre-authentication capabilities for the module. The default is set
      ' to false.

      Public ReadOnly Property CanPreAuthenticate() As Boolean _
       Implements IAuthenticationModule.CanPreAuthenticate


        Get
          Return m_canPreAuthenticate
        End Get
      End Property
