Custom Siteminder Authentication Scheme

Hi,

 I have quite an interesting task at a client site. They use a SSO tool called Siteminder (from Computer Associates) that runs agents on each IIS website

and installs ISAPI filters to intercept web requests and validates them.

The validation uses custom logic developed in C/C++ from the Siteminder SDK.

I have to modify this to support dual authentication (custom + AD) so that if one scheme fails, it tries the other before returning a success or failure.

AD programming is a breeze in dotNet so I would like to convert the C/C++ code to dotNet but still allow Siteminder to be able to talk to my code.

If anyone has any guidelines on how to convert c/c++ code to .Net, it would be appreciated.

If anyone has created a custom authentication provider for Siteminder in dotNet, that would be even better.

Thanks.
