Hello again, I have the newest version of freeradius up and running. I am using rlm_perl and have setup to use Username and password. I was wondering if it's possible to initiate a challenge/response in order to prompt for another piece of data. Example. Domain Username / Domain password and then come back with a request for a one-time password. I tried to return 11; even though it's not listed as a viable return value. Any idea on if this is possible?
