gbraux -> Application filter implementing Layer 3 authentication (25.Apr.2008 9:10:55 AM)
|
Hello,
I am in the way to build an application filter to implement layer 3 authentication in ISA 2004/2006. The authentication token will be in IP header options.
Some questions :
1. I want my APP filter to apply to all ISA protocols, but the "IFWXFilterAdmin::InstallFilter()" function wants a AssociatedProtocols array ... Is there a way to apply the filter to all protocol by defaut ?
2. The APP filter will have to get the token from all data packet incoming from the internal network. Do the SDK provide a easy way to get all incomming data packet (or at least the first packet of the session, to extract the token)?
3. After validating the token, I will get a user SID (token is linked to an Active Directory SID in a SQL database). So I want the session to be "authenticated" by ISA using the SID. I have found a function in the SDK to retrieve user informations (IFWXSession::GetAuthenticatedUser), but no one to set user information ... How to do this ?
Thanks for your replies,
Guillaume
