Creative ways to test /simulate AAA clients ?

[news2010a]

I need to work on a project to implement AAA for VPN and Wireless users.

I configured ACS 3.3 and Active Directory Groups accordingly.

I do not have a Cisco VPN 3000 concentrator or wireless access-points available in the lab.

Can someone suggest a creative way perhaps I could simulate the cisco AAA client (VPN and wireless) to demonstrate that my group mapping in ACS is working accordingly ?

Environment Win2003 AD SP1, Cisco ACS 3.3.

Under Linux use 'radclient' from freeradius. Under Windows you can try utility from radutils.com.
