Interesting (and something to remember in the future) but in my case the -mapall directive should be forcing all NFS users to be creating files a nobody:nobody, but it doesn't seem to be doing that. Not even for root@SGI (who is the only user able to write to the NFS share at all) Hmmm ... -Bill To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
