IAuthenticationModule::CanPreAuthenticate Property

Gets a value indicating whether the authentication module supports preauthentication.

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

property bool CanPreAuthenticate {
	bool get ();
}

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.

   String^ m_authenticationType;
   bool m_canPreAuthenticate;

public:

   // The CustomBasic constructor initializes the properties of the customized 
   // authentication.
   CustomBasic()
   {
      m_authenticationType = "Basic";
      m_canPreAuthenticate = false;
   }


   property String^ AuthenticationType 
   {

      // Define the authentication type. This type is then used to identify this 
      // custom authentication module. The default is set to Basic. 
      virtual String^ get()
      {
         return m_authenticationType;
      }

   }

   property bool CanPreAuthenticate 
   {

      // Define the pre-authentication capabilities for the module. The default is set 
      // to false. 
      virtual bool get()
      {
         return m_canPreAuthenticate;
      }

   }
