I am trying to get sharepoint services to work through the WebVPN on our ASA 5520. We are using passthrough authentication on the IIS of the sharepoint. Is there anything special I need to do to get this particular configuration to work? The closest thing I found was that Cisco fixed this with the 3000 series in 4.7 but nothing related to the ASA platform. I have searched previous threads before I posted and could not find my answer. Any help is appreciated.
