I am running a router connected to an ASA connected to my Windows domain. I am setting up VPNs on the ASA and I was hoping to get some suggestions and opinions on authentication. Should I use IAS (RADIUS) or is there a way to pass authentication directly to Active Directory? Is that was IAS does? I am new to this. We have a small office and have no more then 25-30 clients that will VPN in for remote access.
Thanks for any and all suggestions.
