For this to work you need a system-auth file in /etc/pam.d, which would
have lines for auth/account/required etc, and not just "includes".

PAM seems to be another area on which Linux distributors have been
diverging wildly for a long time; for example here on Debian the include
lines look like

auth    requisite       pam_nologin.so
auth    required        pam_env.so
@include common-auth
@include common-account
session required        pam_limits.so

so I doubt one distro's config files are applicable to any other.
