windows integrated authentication and Oracle

I realize this is a little off-topic, unfortunately there isnt an ado news group.  If someone can reply Im glad to take it offline.

My question is whether anyone has any experience (or knowledge) with an asp.net web app that interfaces with Oracle using windows integrated security.  I believe I read somewheres that its possible, but it means running the accounts under a higher-level of privileges than a normal account does, something like that.

I have a security guy at work intrigued with sql server and integrated security, and I need to be able to tell him if the same can be done with Oracle  and what the ramifications were.

Thanks, Mark
