Hi Peter, Here is some strangeness I have noticed to support your issue.

I?ve seen something very similar - one user in particular cannot write to some filesystems where they can on other clients (Linux, Solaris). Looking at a tcpdump/wireshark analyses of the nfs traffic seems to reveal nothing untoward. This is under Mac OS X 10.6 current patch level but has been seen at the very least since the 10.6 upgrade (around the time of migrating from Linux to OpenSolaris fileserver). Here?s a test I just did logging in and becoming that user (su - ilister): [ilister at hamilton ~]$ cd /mantara/dev [ilister at hamilton dev]$ df -h .
