IAuthenticationModule.CanPreAuthenticate Property

Gets a value indicating whether the authentication module supports preauthentication.

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

bool CanPreAuthenticate { 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.

private string m_authenticationType ;
private bool m_canPreAuthenticate ;

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

// Define the authentication type. This type is then used to identify this 
// custom authentication module. The default is set to Basic. 
public string AuthenticationType
{
  get
  {
    return m_authenticationType;
  }
}

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