programmatic retrieval of authenticated VPN user

[DancingGeek]

Greetings,

Is it possible to get back from a VPN connection the status of a user, i.e. the user has been verified? Not the password, but that a particular user has already been authenticated via the VPN connection, in order to prevent the user from dealing with another logon? If I am posting in the wrong area, please let me know - I'm not sure where to ask this question, but I'm thinking there might be some sort of standard interface.

Cheers!
Sheri

What are you using for a VPN server? What are the clients?

Well, I was hoping for a somewhat generic solution so that it could be used with multiple types of vpns. Am I crazy?

thanks!

Yep. Pretty much. Different types of VPN servers use different forms of authentication. Also, availability of the user status would depend upon what point in the network the connection is made and the type of server.

Should work with radius, either MS native or FreeRadius on linux. Other than that, can't really think of an environment where this would be possible.
