I haven't tried it but if you put Authentication Server (Radius) onto a AD Domain controller you will be able to use AD but the comms between the concentrator and the AD domain controller will be clear text (not encrypted)
The concentrator could authenticate remote access vpn users directly to Active Directory. As long as you define the right domain name, dns name and dns ip of the domain controller. To the concentrator it is the same domain controller authentication, it is not domain controller by itself on the AD tree if that is what you are asking.
If you are operating on mixed mode, you should still be ok. If you are operating on native,
then it would be different, and I would like to clarify my previous statement that I was referring on mixed mode and not native AD. On mixed mode you would still have the same model as the the previous NT Domain, where you would have the Netbios name of the Domain controller
defined on the concentrator. If you are using Native AD. Native AD support is not yet on the current code on the concentrator, it is planned for the release 4.0 of the code. Sorry for the confusion.
