PassportAuthentication Class

Note: This API is now obsolete.

Configures Passport-based authentication in ASP.NET applications.

Namespace:   System.Web.Configuration
Assembly:  System.Web (in System.Web.dll)


[ObsoleteAttribute("This type is obsolete. The Passport authentication product is no longer supported and has been superseded by Live ID.")]
public sealed class PassportAuthentication : ConfigurationElement


This API supports the product infrastructure and is not intended to be used directly from your code. Initializes a new instance of the PassportAuthentication class.


Gets a reference to the top-level Configuration instance that represents the configuration hierarchy that the current ConfigurationElement instance belongs to.(Inherited from ConfigurationElement.)


Gets an ElementInformation object that contains the non-customizable information and functionality of the ConfigurationElement object. (Inherited from ConfigurationElement.)


Gets the ConfigurationElementProperty object that represents the ConfigurationElement object itself.(Inherited from ConfigurationElement.)


Gets or sets a property or attribute of this configuration element.(Inherited from ConfigurationElement.)


Gets or sets a property, attribute, or child element of this configuration element.(Inherited from ConfigurationElement.)


Gets the collection of locked attributes.(Inherited from ConfigurationElement.)


Gets the collection of locked elements.(Inherited from ConfigurationElement.)


Gets the collection of locked attributes (Inherited from ConfigurationElement.)


Gets the collection of locked elements.(Inherited from ConfigurationElement.)


Gets or sets a value indicating whether the element is locked.(Inherited from ConfigurationElement.)


Gets the collection of properties.(Inherited from ConfigurationElement.)


Gets or sets the URL to which the request is redirected.

System_CAPS_protmethodDeserializeElement(XmlReader, Boolean)

Reads XML from the configuration file.(Inherited from ConfigurationElement.)


Compares the current ConfigurationElement instance to the specified object.(Inherited from ConfigurationElement.)


Gets a unique value representing the current ConfigurationElement instance.(Inherited from ConfigurationElement.)


Gets the Type of the current instance.(Inherited from Object.)


Sets the ConfigurationElement object to its initial state.(Inherited from ConfigurationElement.)


Used to initialize a default set of values for the ConfigurationElement object.(Inherited from ConfigurationElement.)


Indicates whether this configuration element has been modified since it was last saved or loaded, when implemented in a derived class.(Inherited from ConfigurationElement.)


Gets a value indicating whether the ConfigurationElement object is read-only.(Inherited from ConfigurationElement.)


Resets the internal state of the ConfigurationElement object, including the locks and the properties collections.(Inherited from ConfigurationElement.)


Resets the value of the IsModified method to false when implemented in a derived class.(Inherited from ConfigurationElement.)

System_CAPS_protmethodSerializeElement(XmlWriter, Boolean)

Writes the contents of this configuration element to the configuration file when implemented in a derived class.(Inherited from ConfigurationElement.)

System_CAPS_protmethodSerializeToXmlElement(XmlWriter, String)

Writes the outer tags of this configuration element to the configuration file when implemented in a derived class.(Inherited from ConfigurationElement.)


Sets the IsReadOnly property for the ConfigurationElement object and all subelements.(Inherited from ConfigurationElement.)


Returns a string that represents the current object.(Inherited from Object.)

System_CAPS_protmethodUnmerge(ConfigurationElement, ConfigurationElement, ConfigurationSaveMode)

Modifies the ConfigurationElement object to remove all values that should not be saved. (Inherited from ConfigurationElement.)

The PassportAuthentication class allows you to access and configure a node in the Machine.config or Web.config configuration file identified by the passport tag.

This type is part of a group that includes the AuthenticationSection, FormsAuthenticationConfiguration, and AuthenticationMode types.


The PassportAuthentication class can write information into the related section of the configuration file at machine, site, or application level only. Any attempt to write in a configuration file at a different level in the hierarchy will result in an error message generated by the parser. You can use this class to read configuration information at any level in the hierarchy.

The following code example shows how to obtain the PassportAuthentication object from the configuration file of an existing Web application. Also shown is a configuration example.

  <passport redirectUrl="Login.aspx"/>

// Get the configuration.
// Get the Web application configuration.
System.Configuration.Configuration configuration = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("/aspnetTest");

// Get the section.
System.Web.Configuration.AuthenticationSection authenticationSection = (System.Web.Configuration.AuthenticationSection)configuration.GetSection("system.web/authentication");

// Get the authentication passport element.
PassportAuthentication passport = authenticationSection.Passport;
