Subject: [PATCH] service: Add "pam" and "nss" services in
 realm_sssd_config_add_domain()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

realm_sssd_config_add_domain() must setup the services line in sssd.conf
otherwise SSSD won't be able to start any of its services.

It's a regression caused by 402cbab which leaves SSSD with no services
line when joining to an ad client doing "realm join ad.example".
