[Zope] NT Authentication?

I'm currently running Zope & ZServer on a FreeBSD 3.3 machine, and would like to be able to authenticate users via the NT server on our LAN. Is that currently possible? Is it even feasible? I'd be happy to change things around and use Apache if that'll help matters. --- Chris Christopher W. Carlson / IS Administrator CertainTeed Corporation / Waco, Texas
