Testing WAD via ntlm_auth

Does anyone have actual examples of radclient (or other command-line tools) being used to test Freeradius using Windows Active Directory authentication via samba/ntlm_auth? I'd like to be able to test Radius authentication for various different categories of user on our Active Directory. Presumably this involves PEAP/MSCHAPv2 I can't work out how to do it without using a Windows client and a wireless infrastructure we don't have yet. (or even if it is doable) I can use radclient to test PAP and "straight" CHAP against locally defined users with cleartext passwords. Time to go one step further.
