Wondering what people are using to provide security from their Wireless
environments to their corporate networks? 2 or more factors seems to be the
accepted standard and yet we're being told that Microsoft's equipment can't
do it. Our system being a Microsoft Domain... seemed logical, but they can
only do 1 factor.
What are you guys using?
Thanks
Move to 802.1X with Radius.
Connect your APs or AP Controllers to a decent OTP system like
otpd+rlm_otp+freeradius and then connect to the Microsoft domain using LDAP.
Extend the LDAP schema to hold the private keys for the OTP system.
Many vendors offer this solution, although I suggest that you don't go with
SecurID or any token vendor that does not disclose their algorithm to you.
Go open, and use OATH.
The work being done on OATH is where future one-time, two-factor systems are
headed:

Tokens are an option but I should have been more clear.
As we're a windows shop (apologies, but that's the way it is), we were
planning on going with user credentials and the machine's domain
certificate. Your solution might still be viable, but I'm not certain if I
can get at the machine certs with LDAP that way,have to check that.
You could always take the route of not trusting the wireless network at all.
Users who get to wireless can only go to the Internet.
Put all the APs in a DMZ.
Users who can open up a VPN to your microsoft vpn servers can authenticate
and get to the corporate network.
This is the way things were done on the Apple campus for a long time.

We use wireless authentication for the purposes of protecting the link layer...
authenticated users are still outside the privileged corprate network and therefore need to vpn in.
