Mounting NFS Shares ... UID Problem

I have two users on a pc who mount their ~/Documents and ~/Mail from my fileserver.
For one user (UID=1000) this is fine, I created /Documents and /Mail while logged in as
that user and the mounted NFS to that place, rw'ed.

UID=1001 has slightly more problems. I create /Documents and /Mail and the NFS shares
are mounted. I then find the owner ship of this has chaged to UID=1000, and so can no longer
be written to from that user!

I log in as root and it says I don't have the permission to change the ownership of UID=1001
/Documents and /Mail!

Please help,


fstab for those who want it:
/dev/hda1 / reiserfs acl,user_xattr 1 1
/dev/hda2 swap swap pri=42 0 0
devpts /dev/pts devpts mode=0620,gid=5 0 0
proc /proc proc defaults 0 0
usbfs /proc/bus/usb usbfs noauto 0 0
sysfs /sys sysfs noauto 0 0
/dev/dvdrecorder /media/dvdrecorder subfs fs=cdfss,ro,procuid,nosuid,nodev,exec,iocharset=utf8 0 0
se:/home/ed/Users/LO/Mail /home/lo/Mail nfs defaults,rw 0 0
se:/home/ed/Users/LO/Documents /home/lo/Documents nfs defaults,rw 0 0

I had the same problem and solved it like this (by nuking nfs' poor security...)

# /etc/exports: the access control list for filesystems which may be exported
# to NFS clients. See exports(5).
/mnt/Shares (rw,anonuid=1000,anongid=1000)
/mnt/Scsi (rw,anonuid=1000,anongid=1000)
/var/www (rw,anonuid=1000,anongid=1000)

if I can remeber well, the "annouid=1000" was the key: your 1000 and 1001 users will read and write as they were both 1000.

hope it will work
