when I crate web application with powershell script this alert message shows.
WARNING: The Windows Classic authentication method is deprecated in this release and the default be
havior of this cmdlet, which creates Windows Classic based web application, is obsolete. It is reco
mmended to use Claims authentication methods. You can create a web application that uses Claims aut
hentication method by specifying the AuthenticationProvider parameter set in this cmdlet. Refer to
the http://go.microsoft.com/fwlink/?LinkId=234549 site for more information. Please note that the d
efault behavior of this cmdlet is expected to change in the future release to create a Claims authe
ntication based web application instead of a Windows Classic based web application.
When I checked the central administration -> Web application -> Authentication Providers
The Membership Provider Name is ‘Windows’ not ‘Claims Based Authentication’
