Is there anythings besides IIS that I can use to get Windows Integrated Authentication?

Question

On a Mac os x server with apache, is there any programming library, framework, etc. that I can get to allow Windows Integrated Authentication? I don't mean just LDAP because the user still has to logon the website before I can get the LOGON_USER. I am looking for something that gets the credentials of the Windows user from the browser (ie). If it uses LDAP I don't care just as long as the user doesn't have to logon to the intranet website.

I have looked for this with J2EE, PHP, Ruby, and more. I have only found unsupported and inactive mods for apache or pay for single sign on products, but nothing foss that is active.

Thank you.

EDIT: I found this. Am I reading it right that that is what I am also asking for?

EDIT: Apparently, jcifs is not supposed to be used for this.
