ClientWindowsAuthenticationMembershipProvider.Logout Method

Logs out the user.

Namespace:  System.Web.ClientServices.Providers
Assembly:  System.Web.Extensions (in System.Web.Extensions.dll)

public void Logout()

For users authenticated through client application services, the static Thread.CurrentPrincipal property is set to a ClientRolePrincipal object that enables access to the configured role service. The Logout method resets the CurrentPrincipal property to a WindowsPrincipal object that contains the current WindowsIdentity. After you call this method, you can no longer retrieve roles for the user through the ClientRoleProvider class. To reauthenticate the current user, call the ClientWindowsAuthenticationMembershipProvider.ValidateUser method.

The following example code demonstrates how to use this method to log out the user.

private void LogoutUsingWindowsAuthentication()
    ClientWindowsAuthenticationMembershipProvider authProvider =
        System.Web.Security.Membership.Provider as
