I see....  So, you are basically exporting a single directory structure (/users) from
your RH6.2 system and mounting it on /users on several other systems and the only
system with problems is the F17 system.  And naturally you've got the same users and
groups on all systems with the same UID/GID's.

The one question that pops to mind is ....  Why have you defined the mount options as
you did on the F17 system and not the RHEL system?  Not that I would think it would
make a difference....but have you tried with the same options on the F17 system?  I'm
wondering if the sec=sys being defined isn't someone causing an issue.
