Migrated CORE to SCALE 21.10.RC1 ... Existing CORE User Can No Longer sudo

Had a CORE user that could sudo ... migrated to 21.10.RC1. Cannot not execute sudo /bin/bash. in CORE I would use this to do iocage jail consoles .... was using this for zfs set mountpoint to manipulate pvc datasets.

error is:

sudo /bin/bash
sudo: unable to open /etc/sudoers: Permission denied
sudo: no valid sudoers sources found, quitting
sudo: error initializing audit plugin sudoers_audit
userid@truenas:~$ client_loop: send disconnect: Connection reset

I can provide any additional information as requested.

Cannot find for some reason SCALE 21.10-RC1 in the affects version(s) field
