NIS users are unable to authenticate unless Jenkins services is started as root:

I have tried adding "jenkins" to group "shadow" and granting read permissions to /etc/shadow for the group but having no luck.  Tried also to downgrade to v1.6 but that didn't help.  We do have it working on a Redhat box when run as "jenkins" with Jenkins v2.204.6.  Do we need to downgrade Jenkins on the Ubuntu box to the older version?
