Root cause:systemd-login service does not work in a NIS environment without nscd installed.
It ends up doing a yp call which is TCP and that is prohibited by configuration. The call fails, a rather meaningless error is returned and pam_systemd fails to setup session. It does not prevent a login because session setup is marked as optional in the corresponding pam files.
Installing nscd bypasses this because it will be going over the nscd unix domain socket which is allowed
IMHO this as a workaround is NOT stable and not guaranteed to work. The config for logind should be relaxed to allow it TCP calls in order to function correctly in PAM environments which use network authentication.
