I am setting up freeradius on pfsense with the google authenticator option following this guide: https://blog.vonhewitt.com/2017/08/pfsense-openvpn-setup-with-freeradius3p3/
However, when I test the authentication under diagnostics > authentication I get the error "authentication failed" when entering username and PIN+OTP as the password. I have blown everything away and rebuilt to no avail. I have tried multiple TOTP google authenticator type apps for the generation of the OTP codes. No one in the #pfsense nor #freeradius IRC chans on freenode had any ideas as to why either. Help me stackexchange-kenobi, you're my only hope..
