How do I figure out whether a web application in my SharePoint 2010 farm is using claims-based or classic authentication mode? I know that authentication provider (default zone) is Windows, but according to this article http://technet.microsoft.com/en-us/library/cc262350.aspx, the authentication mode could be either (claims-based or classic) for the Windows authentication method.
The reason I am asiking this is because I believe there is a difference in setup of our staging and production environments in terms of authentication mode, which is causing issues with user profile extraction.
Thank you in advance for any help with this.
