Hello,

Discovering myself unable to authenticate to one of my systems and
investigating, I found that Duo has made a change that renders the version of
libpam-duo in all current Debian distributions unable to authenticate.

See https://help.duo.com/s/article/9451?language=en_US for more information.

The minimum supported version is now 2.1.0.
