This time replying to group as well :)
That could be it, the cluster has a nis server for user management, so I
guess I need to add the nis client to the MDS. I'd not done this as I
didn't think it would be needed and would prevent the normal users from
logging in directly to the MDS. But thinking about the way Lustre
operates, I can see why it would be needed.
Having installed nis on the MDS i can confirm that this does indeed seem
to have fixed the permissions problem.
Thanks for the speedy replies all.
