Refer to Cisco's documentation on how to setup Radius.  They even go into how to configure Microsoft's IAS.
http://www.cisco.com/warp/public/471/cisco_vpn_msradius.pdf

IAS will use AD for the account database.  The one thing that is not in the Cisco document is that you need to make 
sure that the user account has "dial-in" permission granted as well as being a member of the AD group you setup in the 
Radius Policy.
