I'm splitting this issue into a separate bug report, since it is not
directly related to the v44 to v204 incompatibility.

The attached patch simulates an error condition, and returns
PAM_SESSION_ERR.

As a result, I can no longer login on the console. We should investigate
why, since the pam module is setup as
 session optional pam_systemd.so
in /etc/pam.d/common-session, so this shouldn't happen
