Linux VPN / NT Domain

[Mark Knecht <mknecht controlnet com>]

Hi all,
   This might be slightly off topic. If someone can point me at a better
reflector I would appreciate it.

   We've set up a Linux based VPN server where users can dial in and connect
to our network using a M$ VPN client. This seems to work fine. It's faster
than the equivalent M$ VPN Server and so far everything look promising.

   However, we are unable to get it to authenticate users via the NT domain
PDC. The only way we've been able to get this to work is a set of passwords
on the VPN server itself, which I would rather not do.

   Has anyone set up something like this before? Is it possible to have the
Linux VPN server carry no passwords and get it's OK from the NT PDC?

Thanks in advance,
Mark
