comparing active directory username to sql databases username

[skullblock]

Okay I have a complicated one here I think. Now what I am ask to do is if someone is logged on to a workstation. And then goes to the intranet and clicks on a link that requires login. What I am ask to do is since the user is already logged in on the network is there a way I can use that information to bypass the log in on the clicked link on the intranet? Let me know if you have an answer.

Thank you
