The last piece, last time was that the users were not in the haclient group.

I now have all of that automated during our install but the users are still
getting
an error for access for a time after this is configured, then it starts
working.
We don't have any exiting changes going into the cib.  The only thing that
I did
that might have caused this to start working but it wasn't a write:
cibadmin --query
After that command things seem to work for a role based user with read only
access.
