 TrueNAS uses the `pam_mkhomdir` PAM module in the pam_open_session configuration file to automatically create user home directories if they do not exist.
 `pam_mkhomedir` returns `PAM_PERM_DENIED` if it fails to create a home directory for a user, which eventually turns into a pam_open_session() failure.
 This does not impact other PAM API calls, for example, `pam_authenticate()`.
