The check for the 'nologin' files is disabled when sshd(8) is built
with USE_PAM. The current pam(8) configuration in the default system
does not check for nologin.
The pam_nologin module is not built by default in STABLE. To fix this,
you need to build the module, install it, and then edit pam.conf to
use it.
