I have to setup 2fa on our Cisco equipment. We are currently using Privacy Idea to authenticate our VPN users. Currently our Cisco equipment is configured to use ACS 5.8 for authentication. I want the second factor to use Privacy Idea and the OTP tokens. I am new to Privacy Idea. I have added some test devices to the /etc/raddb/clients.conf file. One problem is I can’t seem to get ACS and Radius to talk. I can ping between ACS and Privacy Idea. I’m not sure of what all needs to be configured for this to work. Any and all assistance is greatly appreciated. Thanks.
