I need to do a setup which I expected to be very common:
Setup freeRadius, google-authenticator with an existing Active Directory to setup 2FA for Horizon View.
Show the qr-code generated by google-authenticator on a website after user authenticated with his Windows-credentials.
I found an ages old article on how to get this done on archive.org.
Unfortunately, the package totp-cgi mentionned there does not exist on Debian AND depends on pam_url --which apparently I cannot build on Debian, and I have no idea if the needed packages still exist on newer versions of centOS.
Displaying qr-codes on website should be problem someone has already solved.
What am I missing?
