Hi all, I'm a little new to Linux, but I have the beginnings down. Here's what I'm looking to do. I need my Linux box (running Unbuntu server 7.10) to authenticate against an external Cisco ACS server. I did some research and it looks like the programs people refer to are "freeRADIUS" and "libpam_radius_auth." I need the Linux box basically to be a client, I don't need it actually be a radius server. What program can I use for that, and how would I go about configuring it correctly to auth. against the ACS?
