No password prompt on lxc exec container login


When I attempt to run the login command in a container I get no password prompt after the user prompt

root@minione-lxd-61546:~# lxc exec driven-bird login
driven-bird login: root

Login incorrect

I remember this used to work for me, thoughts ?

I’m running LXD 3.03 on ubuntu 1804 with kernel 4.15

That behavior from PAM can happen if the user is disabled or if some PAM plugin rejects the user before you even reach the password stage.
