How can I authenticate users using their Windows login credentials?

How can I let my Intraweb XI application authenticate users using their Windows login credenti开发者_Go百科als? The application runs as a service on Windows servers.

We need to only allow network users to access some of our Intraweb applications.

I'm not familiar with Delphi, but it sounds like you want Active Directory integration (assuming here that you already have a AD Infrastructure in place that does the authentication, since you say "Windows login credentials").

If that's the case, then perhaps Deepak Shenoy's white paper on Active Directory Service Interfaces or the Stack Overflow question about integrating Delphi with Active Directory will point you in the right direction.
