[GeoNode-users] Recurring User 'None' Error Geofence/Geoserver

[Michael Fedak]

I am using the latest 2.8.x branch with Geoserver 2.12.2 and I keep
receiving the following error when attempting to run the updatelayers
command (Below).

I am also having trouble with users not being sync'd with geoserver. I have
gone through the documentation for security configuration, and checked that
the geonode role/user apis are accessible to geoserver. As far as I can
tell, nothing is blocking either geonode from reaching geofence or
vice-versa.
