RAS API

Hi,I have an application written in Visual C++ v5, running on NT4 that allows users to dial into a NT box. The users are  prompted for a username/password and then a telnet connection is automatically started to a host. As well as loginname and password authentication there are also various token passing/challenge response authentication systems that can be used. All access to the system is also logged to a SQL server.  What I would like to be able to do is keep the loginname password and token passing/challenege response system but instead of opening a telnet connection somehow start a RAS connection on the incoming port. Therefore after a user has been authenticated using my program a RAS connection is started.  Is this possible?I cannot find much infomation on the RAS api.  The info I have found allows adding entries to the RAS phone book and making outgoing ras calls.Thanks Robert

NationsBank did it this way:


Laptop user Ras's in to a server w/user and pass.  Third-party software security key starts up, asks user for password.  All communication is then secured, server is open for user.  All 700+ servers can be seen in Network Neighborhood for use.  So the third-party key-encryption started after the RAS was up and running on both server and client.

OK, So it is possible. But where do I find the infomation on the APIs to use


Commented:
There's a sample program called Rasberry on VC++ 5.0.  That's for dialling out.

As far as what you're doing goes, what ports are you using?

My idea would be to create a handle to that incoming inetaddr:port and then pass that handle to the ras API's that listen for a connection.

I think you can screw around with handles like that using CreateFile, ReadFile, WriteFile.  That's how I redirected stdout to a socket once.
