how to get NT authentication information

[Cynthia Yao]

I need to redirect the user to a specific portion of another web server based on that user's username. And the username information is stored on the other web server as NT authentication. Is there a way to pull out this information? I heard about JAAS and PAM, but not sure that is what I looking for. Or does anyone has better idea to implementing this?
Thanks

I think LDAP can solve your problem perfectly.
Try it.
