This bug report put me on the right track: https://bugs.freedesktop.org/show_bug.cgi?id=66867, with

/var/log/messages: gnome-session-binary[12345]: ERROR: Failed to connect to system bus: Exhausted all available authentication mechanisms

and associated YPPROC_DOMAIN not found entries.

The NIS domain must be defined and correct in /etc/sysconfig/network so that it's known to dbus when it starts. This is different from CentOS6 and before where the contents of this file largely didn't matter for NIS and /etc/yp.conf was sufficient.
