Thanks! That's fixed it and root on the Linux client now has full read 
access to all the files on the OI server.

The reason I'm doing this is to back up all the ZFS datasets to tapes on 
the Linux box (which is running Bacula and has tape libraries attached) 
before upgrading the OI system from OI 148 to OI 151a5 and then building 
the bacula-fd client on the OI system.

Thanks a lot for your help & have a great weekend.
