Attempting to mount from a Debian 6.0 box gives an "Access denied by server" message and "RPC: server requires stronger authentication" message in that machine's syslog. Using NFSv3 does work in that I can mount directories. >How-To-Repeat: Set up a NFS share in /etc/exports or via ZFS, setting sec=sys as an option Mount the share over the network using -o sec=sys,nfsv4. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
