Authenticate against a domain?

[Chopsaki]

I have an app that uses web services. For someone to login to the app they need to be authenticated (duh). Currently I have a db with un/pwds. I want to use our domain to manage the un/pwds. Is there a way I can make a request for authentication against the domain? I mean if I have the username and password, can I validate it against the domain?

If you guys can give me any pointers on this it would be very helpful!

Thanks in advance.

One thing you can do is client certificate mapping. Your requester includes a client X.509 cert along with their request, and you can map that to a domain user. If it doesn't map, they don't get in.
