I would like to use L2TP instead of pptp for my vpn solution. I am wondering if it is possible to avoid the use of both a Preshared Key or a Certificate. Is it possible to just have the Active directory check the users Login and password to extablish the connection? If yes how is this setup?

sure. since you need use AD's integrated authentication to establish the secure channel, so i think you need use two Windows 2000/2003 servers connect together. for more information, please refer microsoft's vpn site at:


hope it helps,

Your answer was........ Sure
However the correct answer was No it is Not possible to avoid the use of a Pre-shared Key or certificate.
So I don't think I can accept your answer

oh, sorry for my english, hehe. :) it is not my native language. in my native language, if you are wondering or even negating something, and i agree with you, i should say 'YES' to support you; but in english i should say 'NO'. ;))

did you noticed my second sentence in my 1st post? it was "since you need use AD's integrated authentication to establish the secure channel", it was what i wanted to say, hehe.

anyway, if you can not accpet my "SURE", ok, no problem and no objection. :)

Ok, no big deal you can have the points. It was difficult digging through Microsofts Website to find out about IPSec. It seems like they really prefer us to use PPTP but now that IPSec is working I'm happy :)
Thanks for the help

thanks for your points, saunders4tom. :) as for your pptp and ipsec: on microsoft windows platforms, PPTP was implemented early than IPSEC, so you might see more articles about microsoft PPTP. the URL in my first post is microsoft's official VPN site for W2K, if you like some 3rd party solutions or documentations, you may visit here:

VPN - Virtual Private Networking
